Security Orchestration, Automation and Response

Security Orchestration, Automation and Response (SOAR) is an IT stack helping companies and organizations to deal with security threats. In a collection of physical and digital security tools, SOAR provides an architecture for optimal security response. For example, a SOAR resource set could include new kinds of software packages that run on top of firewalls or perimeter security hardware, arranging new and more sophisticated processes beyond simple perimeter security.

Asynchronous Transfer Mode

Asynchronous transfer mode (ATM) is a switching technique used by telecommunication networks that uses asynchronous time-division multiplexing to encode data into small, fixed-sized cells. This is different from Ethernet or internet, which use variable packet sizes for data or frames. ATM is the core protocol used over the synchronous optical network (SONET) backbone of the integrated digital services network (ISDN).

Cheezburger

The word "cheezburger," misspelled with a "z", is based on the idea that cats, if they could write to humans, would have a primitive control of the English language, and would misspell most words. This kind of language has been called "lolspeak" after the phenomenon of "lolcatz" hit the Internet in the mid-2000s.

Data Bleed

The term “data bleed” is now somewhat popular, but also a little hard to define, since the term itself is not well defined on the internet. In general, data bleed occurs when there is not transparency into data use, and users or other parties experience mysterious data quantification, or where data transfers happen without the express permission of the user.

Easter Egg

An Easter egg is a hidden video game feature or surprise. Easter eggs are usually unlocked by using certain techniques to complete in-game tasks, entering specific button combinations or acquiring access to secret game or game file areas.

Hackathon

A hackathon is a gathering where programmers collaboratively code in an extreme manner over a short period of time. Hackathons are at least a few days - or over a weekend - and generally no longer than a week. While working on a particular project, the idea is for each developer to have the ability and freedom to work on whatever he/she wants. A hackathon is also known as a hackfest or hack day.

Yoyo Mode

Yoyo mode refers to a situation wherein a computer or a similar device seems stuck in a loop -- turning on briefly, then turning off again. The idea is that the rapid restart and shut off patterns can be compared to the down and up cycles of a yoyo.

Lexeme

A lexeme is a sequence of alphanumeric characters in a token. The term is used in both the study of language and in the lexical analysis of computer program compilation. In the context of computer programming, lexemes are part of the input stream from which tokens are identified. An invalid or illegal token produces an error. A lexeme is one of the building blocks of language.

Cyber Kill Chain

A cyber kill chain is a collection of processes related to the use of cyberattacks on systems. Some experts describe the cyber kill chain as representing the "stages" of a cyberattack. In general, the cyber kill chain is a step-by-step description of what a complex attack does.

Mechatronics

Mechatronics is a broad engineering field that is based on evaluating mechanical and electrical engineering systems, and working with mechanical and electrical systems. Mechatronics blends mechanical skills and tasks with electronic design. It is sometimes seen as a field similar to robotics.

Evolutionary Algorithm

An evolutionary algorithm is considered a component of evolutionary computation in artificial intelligence. An evolutionary algorithm functions through the selection process in which the least fit members of the population set are eliminated, whereas the fit members are allowed to survive and continue until better solutions are determined. In other words, evolutionary algorithms are computer applications which mimic biological processes in order to solve complex problems. Over time, the successful members evolve to present the optimized solution to the problem.

OpenDNS

OpenDNS is the name of a Domain Name System (DNS) service as well as of the company that provides that service. The OpenDNS service extends the DNS by incorporating features such as content filtering and phishing protection. It is also touted as faster, more reliable and having zero downtime because of its global network of DNS servers that ensures that, if one or two servers are down, the others can still carry the slack.

Cloud Spanning

Cloud Spanning is a type of cloud delivery model in which an application is deployed and executed over multiple simultaneous cloud platforms and infrastructure. Cloud spanning enables a cloud application to distribute its computations and components across one or more cloud environments.

Always On

The tech term "always on"or "always-on" refers to systems that are continuously available, plugged in, or connected to power sources and networks. Always on may also refer to systems that are continually operational - that do not take breaks, but continue to hum along through all hours of the day.

Brute Force Attack

A brute force attack is a trial-and-error method used to obtain information such as a user password or personal identification number (PIN). In a brute force attack, automated software is used to generate a large number of consecutive guesses as to the value of the desired data. Brute force attacks may be used by criminals to crack encrypted data, or by security analysts to test an organization's network security. A brute force attack is also known as brute force cracking or simply brute force.

Hakspeak

Hakspeak is a type of alternative text representation for certain words or characters. It involves substituting numbers or symbols for letters of the English or western alphabet. Other hakspeak systems may also exist for other world languages and alphabets. Based on the term hacker, hakspeak has evolved into a kind of common code used to transmit messages in secret ways geared toward confusing those who are not knowledgeable about the hakspeak system. Hakspeak is also known as leetspeak, leet speak and leetspeek.

Runtime Error

Runtime error refers to an error that takes place while executing a program. As opposed to the compilation errors that occur during a program compilation, runtime errors occur only during the execution of the program. Runtime errors imply bugs in the program or issues that the developers had expected but were unable to correct. For example, insufficient memory can often trigger a runtime error. Runtime errors usually appear in a message box that includes a specific error code coupled with its corresponding description. It is quite common that the computer becomes noticeably slow prior to the appearance of a runtime error.

Bitmap

Bitmap (BMP) is an image file format that can be used to create and store computer graphics. A bitmap file displays a small dots in a pattern that, when viewed from afar, creates an overall image. A bitmap image is a grid made of rows and columns where a specific cell is given a value that fills it in or leaves it blank, thus creating an image out of the data.

Internet Protocol Security

Internet protocol security (IPsec) is a set of protocols that provides security for Internet Protocol. It can use cryptography to provide security. IPsec can be used for the setting up of virtual private networks (VPNs) in a secure manner. Also known as IP Security.

Internet of Things

The internet of things (IoT) is a computing concept that describes the idea of everyday physical objects being connected to the internet and being able to identify themselves to other devices. The term is closely identified with RFID as the method of communication, although it also may include other sensor technologies, wireless technologies or QR codes.

The IoT is significant because an object that can represent itself digitally becomes something greater than the object by itself. No longer does the object relate just to its user, but is now connected to surrounding objects and database data. When many objects act in unison, they are known as having "ambient intelligence."

Internet of Everything

The Internet of Everything (IoE) is a broad term that refers to devices and consumer products connected to the Internet and outfitted with expanded digital features. It is a philosophy in which technology's future is comprised of many different types of appliances, devices and items connected to the global Internet. The term is somewhat synonymous with the Internet of Things (IoT).

Outlier Detection

Outlier detection is the process of detecting and subsequently excluding outliers from a given set of data. An outlier may be defined as a piece of data or observation that deviates drastically from the given norm or average of the data set. An outlier may be caused simply by chance, but it may also indicate measurement error or that the given data set has a heavy-tailed distribution.

Here is a simple scenario in outlier detection, a measurement process consistently produces readouts between 1 and 10, but in some rare cases we get measurements of greater than 20. These rare measurements beyond the norm are called outliers since they "lie outside" the normal distribution curve.

Hyperconverged Infrastructure

A hyperconverged infrastructure is an infrastructure model that utilizes a software-centric architecture and has a tight integration with the storage, networking, computing and virtualization software and hardware resources. A hyper-converged infrastructure enables the management of all the integrated resources from a single common toolset. A hyper-converged infrastructure is an improvement over a converged infrastructure, where the vendor provides a preconfigured bundle of software and hardware as a single unit. This type of infrastructure reduces complexity and helps simplify management of resources. A hyper-converged infrastructure is also known as hyperconvergence.

3V's

3V's is a term used to define the different attributes of big data: volume, variety and velocity. In 2001, the 3V's term was coined to define the constructs or attributes that make up an organization's stored and owned data repositories. 3V's is now used to define the trends and dimensions of big data.

Bit Stuffing

Bit stuffing is the process of inserting noninformation bits into data to break up bit patterns to affect the synchronous transmission of information. It is widely used in network and communication protocols, in which bit stuffing is a required part of the transmission process. Bit stuffing is commonly used to bring bit streams up to a common transmission rate or to fill frames. Bit stuffing is also used for run-length limited coding.

Kali Linux

Kali Linux is a Linux distribution that is specialized for cybersecurity. It is an open-source product that involves a lot of customization for penetration testing, which helps companies to understand their vulnerabilities.

Informatics

Informatics is the study of the behavior and structure of any system that generates, stores, processes and then presents information; it is basically the science of information. The field takes into consideration the interaction between the information systems and the user, as well as the construction of the interfaces between the two, such as the user interface.

DNA Digital Data Storage

DNA digital data storage is the idea of encoding binary data in a DNA molecule and strand. It is a cutting-edge theory of data storage that represents the new frontier of where technology is going in the 21st century along with other major theoretical advances like quantum computing. DNA digital data storage is also known as DNA-based data storage, DNA data storage or DNA storage.

Cloud Sprawl

Cloud sprawl is the uncontrolled proliferation of an organization’s cloud instances or cloud presence. It happens when an organization inadequately controls, monitors and manages its different cloud instances, resulting in numerous individual cloud instances which may then be forgotten but continue to use up resources or incur costs since most organizations pay for public cloud services.

Business Continuity Management

Business continuity management (BCM) refers to the management of core conceptual resources that address future threats to a business and help business leaders handle the impacts of these threats. This term is in the same vein of others, like business continuity planning (BCP), where business leaders try to identify and address potential crises before they occur.

Asynchronous Method Call

An asynchronous method call is a method used in .NET programming that returns to the caller immediately before the completion of its processing and without blocking the calling thread. When an application calls an asynchronous method, it can simultaneously execute along with the execution of the asynchronous method that performs its task. An asynchronous method runs in a thread separate from the main application thread. The processing results are fetched through another call on another thread.

Asynchronous methods help optimize the execution of resources resulting in scalable application. These are used to execute time-consuming tasks such as opening large files, connecting to remote computers, querying a database, calling Web services and ASP.NET Web forms. Asynchronous method call may also be referred to as asynchronous method invocation (AMI).

Stack Environment Control Dump Machine

A Stack Environment Control Dump machine (SECD machine) is an abstract machine made for the implementation of functional programming. A SECD machine contains registers "stack control and dump" and what experts refer to as an associative array in terms of environment, to help with the compiling of functional programming languages.

Superconverged Cloud Infrastructure

A superconverged cloud infrastructure, or superconvergence, is an approach to IT resources that integrates network, storage, compute, virtualization and management in a single platform. Driven by the need for increased operational efficiency, superconvergence reduces performance, resource and usage limitations identified in previous IT infrastructure management approaches. It represents a significant step in the evolution of data center technology.

Cryptographic Key

A cryptographic key is a string of bits used by a cryptographic algorithm to transform plain text into cipher text or vice versa. This key remains private and ensures secure communication. A cryptographic key is the core part of cryptographic operations. Many cryptographic systems include pairs of operations, such as encryption and decryption. A key is a part of the variable data that is provided as input to a cryptographic algorithm to execute this sort of operation. In a properly designed cryptographic scheme, the security of the scheme is dependent on the security of the keys used.

Web of Things (WoT)

The Web of Things (WoT) is a computing concept that describes a future where everyday objects are fully integrated with the Web. The prerequisite for WoT is for the "things" to have embedded computer systems that enable communication with the Web. Such smart devices would then be able to communicate with each other using existing Web standards.

Future Proof

Future proof is a buzzword that describes a product, service or technological system that will not need to be significantly updated as technology advances. In reality, very few things are truly future proof. In any field that depends heavily on technology, a regular cycle of replacing and updating appears to be the norm.

Cardinality

The term “cardinality” in database design has to do with counting tables and values. With that said, cardinality has three main definitions. It can relate to counting the number of elements in a set, identifying the relationships between tables, or describing how database tables contain a number of values, and what those tables look like in general. Cardinality between tables can be one-to-one, many-to-one or many-to-many.

Biometric Engine

A biometric engine is the core program that controlls the different hardware and components of a biometric system. The biometric engine controls the enrollment, capture, extraction, comparison and matching of biometric data from a user. It is based on a set of algorithms that facilitate the steps in the recognition process, as well as the intermediary processes like image enhancement, determining quality and the extraction of distinguishing features.

Minification

Minification is a computer science term for changing code to remove unnecessary characters and elements. By taking out comments and extraneous characters, as well as phrases and elements of a codebase, minification makes files smaller. It is a general best practice in many kinds of coding and codebase handling. Minification is also known as minimization.

Database Column

In the context of relational databases, a column is a set of data values, all of a single type, in a table. Columns define the data in a table, while rows populate data into the table. Most databases also allow columns to contain complex data like images, whole documents, or even video clips. So, a column allowing data values of a single type does not necessarily mean it only has simple text values like. Some databases go even further and allow the data to be stored as a file on the Operating System, while the column data only contains a pointer or link to the actual file. This is done for the purposes of keeping the overall database size manageable -- a smaller database size means less time taken for backups and less time to search for data within the database

Zerg Rush

Zerg rush is a term used in several real-time strategy games (RTS) to describe an overpowering attack by a player against his opponent, usually early in the game. This term was popularized by "StarCraft". The Zerg, the most well-known playable race in the game, has the ability to rapidly produce small and cheap offensive units called zerglings in a short period of time, allowing the player to overwhelm his opponents forces very early in the game.

Ideavirus

An ideavirus is an idea that spreads through various networks like the Internet and grows rapidly within a target population. It usually comes from a single person. The term ideavirus was coined by marketer Seth Godin in his book, "Unleashing the Ideavirus." Like a virus, an ideavirus infects and changes every individual it touches, even in just a very small way. The outcome of this infection may not be noticeable, or it can lead to the creation of new products or companies. With each person influenced, the idea is interpreted, modified and often improved before it is passed on. Viral marketing is based on an ideavirus about a product or service. Technology has made spreading an ideavirus much faster and more powerful than in the past.

B3 Security

B3 security is a security rating used to evaluate the security of computer applications and products to be used within government and military organizations and institutes.

Quux is a meta-syntactic variable name invented only as a kind of nickname or placeholder. Like other variable names such as foo, quux may be used in computer programming as a variable name.

Don't Be Evil

Don't be evil is an informal slogan for Google. This motto was conceived by two Google employees, Paul Buccheit and Amit Patel, in an attempt to promote a corporate culture that put long-term gains and user satisfaction above short-term profits. The company believes this philosophy benefits both users and shareholders and that Internet companies don't need to exploit users to make money. Don't be evil is also incorrectly referred to as do no evil.

A random forest is a data construct applied to machine learning that develops large numbers of random decision trees analyzing sets of variables. This type of algorithm helps to enhance the ways that technologies analyze complex data.

Binhex

BinHex is an encoding system used in converting binary data to text, used by the Macintosh OS to send binary files through email. Conversion of binary data into ASCII characters is done to easily transfer the files from one platform to another, as almost all the computers can handle ASCII text files. BinHex was originally the idea of Tim Mann. He wrote it for the TRS-80 as a stand-alone version of an encoding system. BinHex is similar to Uuencode (Unix to Unix encode) and is a common format for Macintosh files. BinHex files need more space than the original format files and are less likely to be corrupted while in transit between older protocols.A BinHex file generally has a .hqx extension at the end of its filename. Earlier versions had the extension .hex. This term is also known (referenced) as .hqx.

WannaCry

WannaCry is a type of ransomware attack that developed in the spring of 2017 and brought the idea of ransomware threats further into the mainstream. This global attack disabled many systems, including public-service systems such as those supporting hospitals and law-enforcement offices. Experts classified WannaCry as a cryptoworm. The security community responded with a "kill switch" and patches that largely stopped the infection of computers with WannaCry.

Test Set

A test set in machine learning is a secondary (or tertiary) data set that is used to test a machine learning program after it has been trained on an initial training data set. The idea is that predictive models always have some sort of unknown capacity that needs to be tested out, as opposed to analyzed from a programming perspective. A test set is also known as a test data set or test data.

Data Boomerang

A data boomerang is when in-house IT staff are asked to manage a project that was previously deployed on the cloud. The term is used by analogy with the "boomerang generation" of young adults moving back in with their parents.

Query Analysis

Query analysis is a process used in databases which make use of SQL in order to determine how to further optimize queries for performance. Query analysis is an important aspect of query processing as it helps improve overall performance of query processing, which will speed up many database functions and aspects. To do this, a query optimizer analyzes a specific query statement and generates both remote and local access plans to be used on the query fragment, based on the resource cost of each plan. The database will then choose whichever plan it believes will process the query with the least cost in resources.

Extract Transform Load

Extract transform load (ETL) is the process of extraction, transformation and loading during database use, but particularly during data storage use. It includes the following sub-processes:

Retrieving data from external data storage or transmission sources
Transforming data into an understandable format, where data is typically stored together with an error detection and correction code to meet operational needs
Transmitting and loading data to the receiving end

Sandbox

A sandbox is a style of game in which minimal character limitations are placed on the gamer, allowing the gamer to roam and change a virtual world at will. In contrast to a progression-style game, a sandbox game emphasizes roaming and allows a gamer to select tasks. Instead of featuring segmented areas or numbered levels, a sandbox game usually occurs in a "world" to which the gamer has full access from start to finish. A sandbox game is also known as an open-world or free-roaming game.

Decoupled

Decoupled, or decoupling, is a state of an IT environment in which two or more systems somehow work or are connected without being directly connected. In a decoupled microservices architecture, for example, software services have none or very little knowledge about the other services. In theory, this means that a change can be made to one service without the developer having to worry about how the change will impact other services -- as long as the service's application programming interface (API) remains the same.

A decoupled architecture allows software development teams to build, execute, test and debug application modules independently. This approach also allows each module to be developed and maintained by a different team of software developers.

Term of the day - 3

Hot Data

Hot data is data that is frequently accessed and transferred within a given system. Hot data is always in demand and in transit, not stored for long periods of time, and archive requirements for dealing with hot data may be more than those for cold data that is likely to be collected and then sit in a static archive.

Cloud Capitalist

A cloud capitalist is a company that has a business model delivering a product or service that is based entirely in a virtual environment accessed through the internet, or is moving toward that model with its existing business. The products and services offered by cloud capitalists are a break from traditional models in that they are not meant to be downloaded or installed to a computer or wireless device. Instead, the user pays for access to the virtual environment where the product or service can be used. Alternatively, access to the virtual environment may be free, but the product or service is pay per use.

Death by Tweakage

Death by tweakage (DBT) is a slang term that refers to last-minute changes to a product that result in its becoming less functional than it would have otherwise been. Death by tweakage is most often used to refer to software that undergoes major changes or has features added just before the release date. Late-stage changes are usually driven by a desire to match the features and capabilities of similar software that has recently been released.

Swarm intelligence is the idea of coordinating massive numbers of individual technology entities to work together. It is a fundamental concept in IT that has been useful and interesting, as well as a bit threatening, throughout the development of modern technological progress.

JavaBeans

JavaBeans are reusable software components that can be manipulated visually. Practically, they are Java classes that follow certain conventions. Like Java, JavaBeans also follow the "write once run anywhere" paradigm. They are persistant, and have the ability to save, store and restore their state. They are also used to encapsulate many objects in a single bean. Thus, they can be passed around in a single bean object instead of multiple individual objects. JavaBean features such as properties, events and methods are managed by the builder tool. These properties can be customized at design time.

Apache Ant

Apache Ant is a Java-based, open-source software build tool developed by the Apache Software Foundation. It is similar to the "make" utility, but is mainly functional on the Java platform. Unlike make, Ant scripts are written in XML to describe the build process and its dependencies. Portability and simplicity of use are two of the main benefits of Ant.

Virtual Telecommunications Access Method

Virtual Telecommunications Access Method (VTAM) is an IBM application programming interface that allows application programs to communicate or exchange data with external devices such as mainframes, communications controllers, terminals, etc. VTAM helps to abstract these devices into logical units so that developers do not need to know the underlying details of the protocols used by these devices.

Predictive Maintenance

Predictive maintenance plays an important role in industries that requires high availability (HA) for machine parts. PdM can be contrasted with reactive maintenance and preventive maintenance.

Reactive Maintenance – Run equipment until it breaks and then fix or replace it.

Preventive Maintenance – Replace parts and schedule equipment repairs on a time- or machine-run-based schedule.

Predictive Maintenance – Use intelligent sensors to monitor machine parts in operations and machine learning to determine when data has deviated from desired parameters.

Predictive maintenance software uses data produced by Internet of Things (IoT) and Industry 4.0 edge nodes to monitor the condition of mechanical assets as they are operating. Consumer-grade predictive maintenance software apps will typically issue an alert when data suggests a replacement part or maintenance appointment is needed.

In contrast, some enterprise-level PdM software applications are able to connect to other business systems and actually order replacement parts and set up appointments so repairs can be made. Popular enterprise PdM vendors include Fxix, UpKeep and eMaint.

State Machine

A state machine is a concept used in designing computer programs or digital logic. There are two types of state machines: finite and infinite state machines. The former is comprised of a finite number of states, transitions, and actions that can be modeled with flow graphs, where the path of logic can be detected when conditions are met. The latter is not practically used.

A state machine is any device storing the status of something at a given time. The status changes based on inputs, providing the resulting output for the implemented changes. A finite state machine has finite internal memory. Input symbols are read in a sequence producing an output feature in the form of a user interface.

State machines are represented using state diagrams. The output of a state machine is a function of the input and the current state. State machines play a significant role in areas such as electrical engineering, linguistics, computer science, philosophy, biology, mathematics, and logic. They are best used in the modeling of application behavior, software engineering, design of hardware digital systems, network protocols, compilers, and the study of computation and languages.

Air Gap

An air gap is a security measure in which computers, computer systems or networks are not connected in any way to any other devices or networks. This is used in instances requiring airtight security without the risk of compromise or disaster. It ensures total isolation of a given system — electromagnetically, electronically and, most importantly, physically — from other networks, especially those that are not secure. In other words, data can only be transferred by connecting a physical device to it, such as a flash drive, external hard disk or DVD.

The term “air gap” is a merely metaphoric description of the conceptual gap required by the physical separation between the computers. Air-gapped networks and computers are used when maximum security of that system or the data stored in it must be ensured. Air gaps protect systems from malware, keyloggers, ransomware or other unwanted accesses. Typical examples include life-critical power plant controls, military and aviation computers, government networks, financial computer systems or computerized medical equipment, among others.

A lot of traditional electronic equipment like thermostats and home appliances have always been air-gapped due to their inherent limits rather than for security reasons. However, with the widespread diffusion of wireless components and “smart” devices, these products are no longer air-gapped, as they are connected to the internet.

Technically, even a simple desktop PC that is not connected to the internet could be considered an air-gapped system. An air gap is also known as an air wall.

Self-Supervised Learning (SSL)

Self-supervised learning (SSL) is an approach to machine learning allows machine learning algorithms to use observed inputs to predict unknown inputs. An important goal for self-supervised learning is to programmatically change unsupervised learning models into supervised learning models by developing pre-training deep learning systems that can learn to fill in missing information.

BERT (Bidirectional Encoder Representations from Transformers) and Q Learning are perhaps two of the most well-known applications of self-supervised learning in AI. During the pre-training phase, each system is shown a short example of text in which some of the words are missing. The systems are then trained how to extract supervisory signals from the input data in order to predict the missing words accurately. SSL and has played an important role in the development of natural language processing (NLP). It is one of several approaches being studied to reduce the need for massive amounts of data to train AI learning algorithms.

Distro

Distro is IT vernacular for a Linux operating system (OS). It is a shortened version of the term distribution. The singular and the plural (distro vs distros) are often used synonymously.

Blind Drop

A blind drop is a hidden location where a malware program, Trojan or virus drops information gathered from a host. The automatically gathered data remains in that location until it is retrieved by the attacker. The data could be credit card or bank account details, usernames and passwords or any personal information the attacker may use to hack into the host's accounts. It is very hard to detect where data is coming from or where it is going, even if the location is discovered.

Fog Computing

Fog computing is a term for an alternative to cloud computing that puts some kinds of transactions and resources at the edge of a network, rather than establishing channels for cloud storage and utilization. Proponents of fog computing argue that it can reduce the need for bandwidth by not sending every bit of information over cloud channels, and instead aggregating it at certain access points, such as routers. This allows for a more strategic compilation of data that may not be needed in cloud storage right away, if at all. By using this kind of distributed strategy, project managers can lower costs and improve efficiencies.

Symmetric encryption is a form of computerized cryptography using a singular encryption key to guise an electronic message. Its data conversion uses a mathematical algorithm along with a secret key, which results in the inability to make sense out of a message. Symmetric encrpytion is a two-way algorithm because the mathematical algorithm is reversed when decrypting the message along with using the same secret key. Symmetric encryption is also known as private-key encryption and secure-key encryption.

One-Time Password

A one-time password (OTP) is type of password that is valid for only one use. It is a secure way to provide access to an application or perform a transaction only one time. The password becomes invalid after it has been used and cannot be used again.

Multithreading

Multithreading is a CPU (central processing unit) feature that allows two or more instruction threads to execute independently while sharing the same process resources. A thread is a self-contained sequence of instructions that can execute in parallel with other threads that are part of the same root process. Multithreading allows multiple concurrent tasks can be performed within a single process. When data scientists are training machine learning algorithms, a multithreaded approach to programming can improve speed when compared to traditional parallel multiprocessing programs.

Even though it’s faster for an operating system (OS) to switch between threads for an active CPU task than it is to switch between different processes, multithreading requires careful programming in order to avoid conflicts caused by race conditions and deadlocks. To prevent race conditions and deadlocks, programmers use locks that prevent multiple threads from modifying the value of the same variable at the same time.

Flash Storage

Flash storage describes any type of long-term storage repository supported by flash memory. Flash storage may also be referred to as solid state storage. Unlike traditional hard disk drive storage, flash storage has no mechanical parts which makes it a good choice for storage in mobile technology. Flash storage comes in a variety of formats and prices, ranging from inexpensive consumer-grade USB drives to enterprise-level all flash arrays.

Fixed Wireless Access (FWA)

Fixed wireless access (FWA) is an alternative way for an Internet Service Provider (ISP) to provide small businesses and homes with last mile connectivity. Fixed Wireless Access uses radio waves to create a connection between a Point-of-Presence cell tower and an external antenna located on the customer's home or business. When the antenna picks up a radio signal, it forwards the signal wirelessly to a special type of modem that converts the radio waves into WiFi signals.

As 5G coverage expands, FWA is expected to provide ISPs with a cost-effective alternative to DSL, fiber optics and cable, especially in geographical locations where it has been cost-prohibitive for ISPs to lay cable or fiber. Because FWA can provide high speeds with low latency, it's expected to compete with satellite connections in many parts of the world and help reduce the digital divide now that 97% of the world's population lives within reach of a mobile cellular signal.

Software as a Service (SaaS)

Software as a service (SaaS) is a software distribution model that delivers application programs over the Internet. End users can access SaaS cloud apps with a web browser. The SaaS provider is responsible for hosting and maintaining the application throughout its lifecycle.

A graph database is a type of NoSQL database that stores data in collections of nodes and edges instead of a series of columns and rows. Each node represents a data point and each edge defines a relationship between two nodes. Graph databases use graph theory models to illustrate how data points are related. This type of database is useful for storing data that has complex, indirect relationships and querying the shortest path between two data points. A graph database may also be referred to as a knowledge graph or graph-oriented database. Popular graph database platforms include Neo4j, Tigergraph and Amazon Neptune.

Session Cookie

A session cookie is a file containing an identifier (a string of letters and numbers) that a website server sends to a browser for temporary use during a limited timeframe. Session cookies are enabled by default. Their purpose is help individual web pages load faster and improve navigation through a website. Each time the browser requests a web page from the server, it includes the session cookie file with its request. The cookie lets the server know which page components the browser has already been sent, so the server doesn't waste time re-sending them. When the browser closes at the end of a session, the file is deleted.

A session cookie is also known as transient cookie. This type of cookie is stored in temporary memory and is only available during an active browser session. End users can adjust browser settings to decline session cookies, however this often results in a poor user experience.

Finally Block

A finally block, in the context of C#, refers to a block of statements that are always executed, regardless of unexpected events or exceptions that may occur during an application's execution. It is used optionally with the "try/catch" block and guarantees the execution of any code that must be executed before exiting the "try" block, regardless of the success or failure of the application's execution. The execution of a finally block is intended to release resources, such as database connections, which are usually available in limited quantities. By this mechanism, the disposal of resources occurs earlier than the garbage collector's finalization operation, thereby optimizing memory.

Capsule Network

A capsule network is a kind of shorthand term for a specific kind of neural network pioneered by Stanford scientist Geoffrey Hinton. In the capsule network, specific methodology is applied to image processing to try to affect an understanding of objects from a three-dimensional spectrum.

Network as a Service

Network as a service (NaaS) is a term that has arisen in the pantheon of software as a service (SaaS) options that are now popular in today's enterprise IT world. Network as a service consists of offering network functionality on a subscription basis, often through the cloud. Network as a service providers virtualize the network setup and give customers the ability to utilize a network that is not really set up in on-premises hardware.

Blockchain Economy

Blockchain economy is a term for a move toward cryptocurrencies and digital ledger systems, and away from traditional national hard currencies and legacy ledger systems. In the blockchain economy, technologies like bitcoin and blockchain are the typical tools for financial management, rather than traditional software programs managing national currencies.

Omnidirectional Treadmill

An omnidirectional treadmill is a mechanical construction that allows for multidirectional movement in a three-dimensional space. Unlike a traditional treadmill that only works in one direction, the omnidirectional treadmill registers movement in all directions and responds to it
with the equivalent treadmill motion.

Progressive Web App

A progressive web app (PWA) is a browser-based application that has become an alternative to a native mobile app. Experts describe PWAs as web apps that “look and feel” similar to a native mobile app.

Autoencoder

An autoencoder (AE) is a specific kind of unsupervised artificial neural network that provides compression and other functionality in the field of machine learning. The specific use of the autoencoder is to use a feedforward approach to reconstitute an output from an input. The input is compressed and then sent to be decompressed as output, which is often similar to the original input. That is the nature of an autoencoder – that the similar inputs and outputs get measured and compared for execution results. An autoencoder is also known as an autoassociator or diabolo network.

Cryptocurrency Exchange

A cryptocurrency exchange is any system that operates on the basis of trading cryptocurrencies with other assets. Like a traditional financial exchange, the cryptocurrency exchange's core operation is to allow for the buying and selling of these digital assets, as well as others. A cryptocurrency exchange is also known as a digital currency exchange (DCE).

Business Continuity Plan

A business continuity plan (BCP) is a plan to help ensure that business processes can continue during a time of emergency or disaster. Such emergencies or disasters might include a fire or any other case where business is not able to occur under normal conditions. Businesses need to look at all such potential threats and devise BCPs to ensure continued operations should the threat become a reality.

A business continuity plan involves the following:

    Analysis of organizational threats
    A list of the primary tasks required to keep the organization operations flowing
    Easily located management contact information
    Explanation of where personnel should go if there is a disastrous event
    Information on data backups and organization site backup
    Collaboration among all facets of the organization
    Buy-in from everyone in the organization

Access Modifiers

Access modifiers are keywords used to specify the accessibility of a class (or type) and its members. These modifiers can be used from code inside or outside the current application. Access modifiers in .NET are used to control the accessibility of each of the members of a type from different possible areas of code. This can be handled from within the current assembly or outside it. An assembly represents a logical unit of functionality and consists of types and resources located in one or more files.

The purpose of using access modifiers is to implement encapsulation, which separates the interface of a type from its implementation. With this, the following benefits can be derived:

Prevention of access to the internal data set by users to invalid state.
Provision for changes to internal implementation of the types without affecting the components using it.
Reduction in complexity of the system by reducing the interdependencies between software components

Non-Deterministic Turing Machine

A non-deterministic Turing machine is a theoretical type of computer in which specific commands may allow for a range of actions, rather than a specific command leading to only one allowable action in the deterministic model of computing. Where deterministic programming is a simple condition of "input X leads to action Y", a non-deterministic Turing machine setup would theoretically allow for input X to lead to a variety of actions Y(array).

Real-Time Strategy

Real-time strategy (RTS) refers to a time-based video game that centers around using resources to build units and defeat an opponent. Real-time strategy games are often compared to turn-based strategy games, where each player has time to carefully consider the next move without having to worry about the actions of his opponent. In real-time strategy games, players must attempt to build their resources, defend their bases and launch attacks while knowing that the opponent is scrambling to do the same things. A real-time strategy game may also be referred to as a real-time simulation or a real-time war game.

The business intelligence architect will generally be responsible for creating or working with these architectures, which serve the specific purpose of maximizing the potential of data assets.

Narrow Artificial Intelligence (Narrow AI)

Unlike general artificial intelligence, which seeks to mimic complex thought processes, narrow AI is designed to successfully complete a single task without human assistance. Popular applications for narrow AI include language translation and image recognition.

Most AI applications in use today can be categorized as being narrow AI. Narrow AI may also be referred to as weak AI.

Narrow Continuous Integration Learning

In software development, continuous integration (CI) is the practice of regularly committing code changes to a version control system that can test and deploy code automatically. The term is often mentioned in tandem with continuous delivery, an approach in which code is tested automatically, but is released into production manually. CI/CD uses an iterative approach to releasing code and can be contrasted with the traditional waterfall method of software development.

Integration Platform as a Service (iPaaS)

Integration platform as a service (iPaaS) is a cloud service that allows software developers to automate how on-premises and cloud-based applications securely share data. An important goal of iPaaS is to simplify management of complex hybrid cloud and multi-cloud architectures. The challenge is that even when simplified, real-time data flows in hybrid and multi-cloud environments can still be very complex.

iPaaS cloud services provide customers with access to an executive dashboard that can easily be customized with pre-built connectors and business rules. The service provider is responsible for handling the back-end services that support hardware management and data governance, including encryption. To accommodate small and mid-size businesses, an increasing number of iPaaS vendors are offering low-code/no-code (LCNC) versions of their iPaaS services. LCNC dashboards allow non-technical line of business (LOB) employees to connect on-premises and cloud applications and synchronize data flows without help from their IT department.

Appending Virus

An appending virus is a type of virus that adds its code to the end of the file of a host program. Its goal is not to destroy the host program, but to slightly modify it so that it will hold the virus code while continuing to operate.

The appending virus copies the first bytes of its code to a safe location and then adds a jump to its code at the beginning of the program that is to run just before the host takes control. Contrary to an overwriting virus, this virus does not permanently destroy any part of the host program, which makes it more difficult to detect the infection.

ACCDB File Format

The .accdb file format is the default file-saving format for the Microsoft Access 2007 and 2010 database applications. Previous versions of Microsoft Access, like 2000 and 2003, use the .mdb file format by default.

Candidate Key

A candidate key is a column, or set of columns, in a table that can uniquely identify any database record without referring to any other data. Each table may have one or more candidate keys, but one candidate key is unique, and it is called the primary key. This is usually the best among the candidate keys to use for identification. When a key is composed of more than one column, it is known as a composite key.

Banker Trojan

A banker Trojan is a piece of malware intended to get financial information or hack users through a banking or financial system, commonly through an online banking or brokerage interface.

Rotoscoping is a technique used in physical animation. This technique allows human users to trace drawings frame by frame. It can also bring a sense of realism to projects and was heavily used in developing the kinds of modern physical animation used today.

Operating System Virtualization

Operating system virtualization (OS virtualization) is a server virtualization technology that involves tailoring a standard operating system so that it can run different applications handled by multiple users on a single computer at a time. The operating systems do not interfere with each other even though they are on the same computer. In OS virtualization, the operating system is altered so that it operates like several different, individual systems. The virtualized environment accepts commands from different users running different applications on the same machine. The users and their requests are handled separately by the virtualized operating system. Also known as operating system-level virtualization.

Self-Replicating Machine

Self-replicating machines are a category of autonomous robot that can make copies or reproduce themselves autonomously with help of raw materials from the existing environment.

The goal of Web mining is to look for patterns in Web data by collecting and analyzing information in order to gain insight into trends, the industry and users in general.

Bitcoin (BTC)

Bitcoin is a digital cryptocurrency made up of processed data blocks used for online and brick-and-mortar purchases. Because bitcoins are limited and their value is determined by market forces, bitcoins are also traded like stocks on various exchanges. Relatively new and experimental, bitcoin is described as “the first decentralized digital currency.”

Whaling

Whaling is a specific kind of malicious hacking within the more general category of phishing, which involves hunting for data that can be used by the hacker. In general, phishing efforts are focused on collecting personal data about users. In whaling, the targets are high-ranking bankers, executives or others in powerful positions or job titles.

Hand Coding

Hand coding involves writing functional code or layout directions in the basic languages in which they are compiled. The alternative is to use various kinds of tools to implement coding conventions without having to hand code them in the original languages.

Node

A node is a point of intersection/connection within a data communication network. In an environment where all devices are accessible through the network, these devices are all considered nodes. The individual definition of each node depends on the type of network it refers to. For example, within the physical network of a smart home domotics system, each home appliance capable of transmitting or receiving information over the network constitutes a node. However, a passive distribution point such as a patch panel would not be considered a node.

Nodes create, receive and communicate information and store it or relay it to other nodes. For example, a scanner in a computer network creates images and sends them to a computer, while a router organizes data received from the internet and distributes it to the individual devices within the network. The concept of nodes works on several levels, but the big-picture view defines nodes as the major centers through which internet traffic is typically routed. This usage is somewhat confusing, as these same internet nodes are also referred to as internet hubs.

In general, POS refers to the place where purchases happen, for instance, at a cashier�s kiosk or at a hostess desk (or side table) at a restaurant.

Data Exhaust

Data exhaust refers to the data generated as trails or information byproducts resulting from all digital or online activities. These consist of storable choices, actions and preferences such as log files, cookies, temporary files and even information that is generated for every process or transaction done digitally. This data can be very revealing about an individual, so it is very valuable to researchers and especially to marketers and business entities.

Hidden Markov Model

A hidden Markov model (HMM) is a kind of statistical model that is a variation on the Markov chain. In a hidden Markov model, there are "hidden" states, or unobserved, in contrast to a standard Markov chain where all states are visible to the observer. Hidden Markov models are used for machine learning and data mining tasks including speech, handwriting and gesture recognition.

Zombie VM

A zombie VM is a virtual machine that is not functioning properly in a software environment, but continues to operate, sucking up resources and providing no value.

Van Eck Phreaking

Van Eck phreaking is a form of digital espionage whereby an eavesdropper detects and analyzes digital signals using equipment that can pick up the electromagnetic emissions put out by a cathode ray tube (CRT) or LCD display. This makes it possible for someone to read the images on another person's display from a distance. There are ways to obscure or reduce display emission in order to thwart Van Eck phreaking, but they are not commercially viable because the security risk that Van Eck phreaking poses to the general public is considered to be very small. This is because Van Eck phreaking requires specialized knowledge and decoding equipment that is not widely available. Highly sensitive computer networks do, however, use Faraday cages to prevent any possibility of a breach via Van Eck phreaking.

Virtual To Physical

Virtual to physical (V2P) is the process of converting or porting a virtual machine (VM) onto and/or as a standard physical machine. V2P allows a VM to transform into a physical machine without losing its state, data and overall operations. Virtual to physical is also known as virtual to physical migration (V2P migration).

Machine-oriented high-level language primarily enables building programs in assembly language or machine language to gain more control over the underlying hardware architecture.

Collaboration Data Objects

Collaboration Data Objects (CDO) is an application programming interface (API) built into Microsoft Server products. CDO provides access to the global address list, mailbox content, public folders and other server objects related to messaging and Microsoft Outlook. CDO cannot be used to directly program added functionality to MS Outlook. The function library of CDO gives developers a convenient way to create, manipulate and send Internet messages, which is not possible with applications such as Microsoft Outlook. Collaboration Data Objects was previously known as OLE Messaging or Active Messaging.

Machine-Generated Data

Machine-generated data are information that is the explicit result of a computer process or application process, created without human intervention. This means that data manually entered by an end-user are definitely not considered as machine-generated. These data cross all sectors, which make use of computers in any of their daily operations and humans increasingly generate this data unknowingly, or at least cause it to be generated by the machine.

Edge Computing

Edge computing in IT is defined as the deployment of data-handling activities or other network operations away from centralized and always-connected network segments, and toward individual sources of data capture, such as endpoints like laptops, tablets or smartphones. Through this type of network engineering, IT professionals hope to improve network security and enhance other network outcomes.

Containerization

Containerization is a type of virtualization strategy that emerged as an alternative to traditional hypervisor-based virtualization. As with the latter, container-based virtualization involves creating specific virtual pieces of a hardware infrastructure, but unlike the traditional approach, which fully splits these virtual machines from the rest of the architecture, containerization just creates separate containers at the operating system level.

Digital Forensics

Digital forensics is the process of uncovering and interpreting electronic data. The goal of the process is to preserve any evidence in its most original form while performing a structured investigation by collecting, identifying and validating the digital information for the purpose of reconstructing past events. The context is most often for usage of data in a court of law, though digital forensics can be used in other instances.

Virtual Infrastructure

A virtual infrastructure is a software-based IT infrastructure being hosted on another physical infrastructure and meant to be distributed as a service as in cloud computing's Infrastructure as a Service (IaaS) delivery model. It provides organizations, particularly smaller ones, that cannot afford to build their own physical infrastructure, access to enterprise-grade technology such as servers and applications. The distribution is often done via the cloud, meaning over large networks such as the Internet.

Robotic Process Automation

Robotic process automation (RPA) is the practice of automating routine business practices with "software robots" that perform tasks automatically. These tasks include transaction processing, IT management and automated online assistants. These software robots could replace human beings for common tasks.

Snowshoe Spamming

Snowshoe spamming is a strategy in which spam is propagated over several domains and IP addresses to weaken reputation metrics and avoid filters. The increasing number of IP addresses makes recognizing and capturing spam difficult, which means that a certain amount of spam reaches their destination email inboxes. Specialized spam trapping organizations are often hard pressed to identify and trap snowshoe spamming via conventional spam filters. The strategy of snowshoe spamming is similar to actual snowshoes that distribute the weight of an individual over a wide area to avoid sinking into the snow. Likewise, snowshoe spamming delivers its weight over a wide area to remain clear of filters.

Metadata

Metadata is data about data. In other words, it is data that is used to describe another item's content. The term metadata is often used in the context of Web pages, where it describes page content for a search engine.

Cryptocurrency Exchange

A cryptocurrency exchange is any system that operates on the basis of trading cryptocurrencies with other assets. Like a traditional financial exchange, the cryptocurrency exchange's core operation is to allow for the buying and selling of these digital assets, as well as others. A cryptocurrency exchange is also known as a digital currency exchange (DCE).

FTP Server

The primary purpose of an FTP server is to allow users to upload and download files. An FTP server is a computer that has a file transfer protocol (FTP) address and is dedicated to receiving an FTP connection. FTP is a protocol used to transfer files via the internet between a server (sender) and a client (receiver). An FTP server is a computer that offers files available for download via an FTP protocol, and it is a common solution used to facilitate remote data sharing between computers.

An FTP server is an important component in FTP architecture and helps in exchanging files over the internet. The files are generally uploaded to the server from a personal computer or other removable hard drives (such as a USB flash drive) and then sent from the server to a remote client via the FTP protocol.

An FTP server needs a TCP/IP network to function and is dependent on the use of dedicated servers with one or more FTP clients. In order to ensure that connections can be established at all times from the clients, an FTP server is usually switched on; up and running 24/7.

An FTP server is also known as an FTP site or FTP host.

Delegated Proof of Stake (DPoS)

Delegated proof of stake (DPoS) is a verification and consensus mechanism in the blockchain. It competes with other proof of work and proof of stake models as a way to verify transactions and promote blockchain organization.

Clustering

Clustering, in the context of databases, refers to the ability of several servers or instances to connect to a single database. An instance is the collection of memory and processes that interacts with a database, which is the set of physical files that actually store data. Clustering offers two major advantages, especially in high-volume database environments:

Fault tolerance: Because there is more than one server or instance for users to connect to, clustering offers an alternative, in the event of individual server failure.

Load balancing: The clustering feature is usually set up to allow users to be automatically allocated to the server with the least load.

Soft Robotics

Soft robotics is the subset of robotics that focuses on technologies that more closely resemble the physical characteristics of living organisms. Experts describe the soft robotics approach as a form of biomimicry in which the traditionally linear and somewhat stilted aspects of robotics are replaced by much more sophisticated models that imitate human, animal and plant life.

Brooks' Law

Brooks’ Law refers to a well-known software development principle coined by Fred Brooks in The Mythical Man-Month. The law, "Adding manpower to a late software project makes it later," states that when a person is added to a project team, and the project is already late, the project time is longer, rather than shorter.

Cluster Analysis

Cluster analysis is a statistical classification technique in which a set of objects or points with similar characteristics are grouped together in clusters. It encompasses a number of different algorithms and methods that are all used for grouping objects of similar kinds into respective categories. The aim of cluster analysis is to organize observed data into meaningful structures in order to gain further insight from them.

Distributed System

A distributed system is any network structure that consists of autonomous computers that are connected using a distribution middleware. Distributed systems facilitate sharing different resources and capabilities, to provide users with a single and integrated coherent network. The opposite of a distributed system is a centralized system. If all of the components of a computing system reside in one machine, as was the case with early mainframes such as Von Neumann machines, it is not a distributed system.

Hashing

Hashing is the process of translating a given key into a code. A hash function is used to substitute the information with a newly generated hash code. More specifically, hashing is the practice of taking a string or input key, a variable created for storing narrative data, and representing it with a hash value, which is typically determined by an algorithm and constitutes a much shorter string than the original. The hash table will create a list where all value pairs are stored and easily accessed through its index. The result is a technique for accessing key values in a database table in a very efficient manner as well as a method to improve the security of a database through encryption.

Hashing makes use of algorithms that transform blocks of data from a file in a much shorter value or key of a fixed length that represent those strings. The resulting hash value is a sort of concentrated summary of every string within a given file, and should be able to change even when a single byte of data in that file is changed (avalanche effect). This provides massive benefits in hashing in terms of data compression. While hashing is not compression, it can operate very much like file compression in that it takes a larger data set and shrinks it into a more manageable form. Suppose you had "John's wallet ID" written 4000 times throughout a database. By taking all of those repetitive strings and hashing them into a shorter string, you’re saving tons of memory space.

Breadcrumb Navigation

Breadcrumb navigation is a tool used in Web searches that allows users to retrace their steps, or go back to a point in time that relates to their original search. Breadcrumb navigation derived its name from the fairy tale "Hansel and Gretel", in which the two main characters used a breadcrumb trail to find their way back home. Breadcrumb navigation links the user back to the prior website page in the overall online route. In other words, the breadcrumb trail will allow the user to backtrack through the previous pages. Breadcrumb navigation may also be called a breadcrumb trail or a cookie crumb trail.

Empowered Edge

Empowered edge is a term in IT that is used to talk about empowering computing centralization that is distributed toward the edge of a network, toward the end user and the end user device. It is a key concept in device management in the cloud and big data age. Empowered edge is also known as device democracy.

In computer science, undefined behavior happens when a computer language does not handle a certain operation that is coded into a codebase. Some experts describe this as “assumptions made by translators of a source code,” suggesting that when there is not a procedure for a certain syntax, that leads to a problem that is hard to predict in terms of its resolution.

Bandwidth Shaping

Bandwidth shaping is the process of allocating parts of network connections as well as establishing bandwidth usage amounts that correspond to activity types. As it relates ISPs, the term refers to the limitations they set to manage the amount of bandwidth individual consumers use so that no one user can obtain a disproportionate amount of control over the Internet gateway.

Cross-Browser

Cross-browser refers to the ability of a website, HTML construct, application or even client-side script to work in several different environments, ones that provide its required features. Similar to the way a cross-platform program is one that can run across multiple computer platforms, cross-browser websites are capable of running in several browsers.

Embedded Intelligence

Embedded intelligence is a term for a self-referential process in technology where a given system or program has the ability to analyze its own operations.

Typosquatting is a questionable technique used by a cybersquatter to attract website traffic by redirecting common typos of popular search terms or major websites to their own sites. Cybersquatters may try to sell products, install malware on a user's machine or even make an opposing political statement. The extreme version of typosquatting is similar to phishing, where an impostor website mimics a real site, thus providing the user with a false impression that he or she has accessed the correct web page.

Zombie Cookie

A zombie cookie is an HTTP cookie that returns to life automatically after being deleted by the user. Zombie cookies are recreated using a technology called Quantcast, which creates Flash cookies to trace users on the internet. The Flash cookies are then used to recreate browser cookies, becoming zombie cookies that never die.

Ransomware

Ransomware is a type of malware programming that infects, locks or takes control of a system. The attacker then requests a financial payment to undo the malicious action. Ransomware attackers typically encrypt files and demand digital currency in exchange for the correct decryption key. The attacker may threaten to leak exfiltrated data to the public or post it for sale on the dark web if the ransom is not paid. Ransomware is distributed through malicious email attachments, infected downloads and compromised websites. The attacker will typically demand payment in a specific cryptocurrency, such as Bitcoin, to avoid detection through conventional follow-the-money tracing methods used by law enforcement. Ransomware may also be referred to as a crypto-virus, crypto-Trojan or crypto-worm.

Microservices

A microservice is a modular software component that does one defined job. Microservices, which have become the default architecture for software development, can run as processes in application servers, virtual machines (VMs) and containers. Each microservice is a mini-application that has its own business logic and adapters for carrying out functions such as database access and messaging. Microservices typically communicate with each other using Application Programming Interfaces (APIs).

Edge Computing

Edge computing is the practice of processing data as close to its source as possible in order to reduce network latency by minimizing communication time between clients and servers. In an edge computing network architecture, data that was traditionally sent to the cloud or a central data center is processed locally, close to where the data originated. The benefits of edge computing include data-stream acceleration and real-time data processing without latency. This approach to processing data at the edge of the network also allows threat monitoring and network analytic tools to be deployed where they’re needed most.

Blockchain

Blockchains are lists of records that are linked together using cryptography. Each record is called a block. The blocks contain the record data and a cryptographic hash to the previous block in the chain. The cryptographic hash is created using the data in the record. So, if any of the data is changed, the link to that data will no longer be valid. This linking creates a secure record history because it is not possible to change a record without altering all the subsequent blocks attached to it, referred to as an immutable ledger. Blockchains are used to record cryptocurrency transactions. The structure of blockchains allows both parties to efficiently verify the transaction.

Because it is the structure of the data that secures the information, blockchains allow transaction records to be open and distributed. All parties can access the entire record of transactions. This allows users to verify that funds are available before a transaction and blockchains create a secure record of the transaction. This makes it harder for someone to make a fraudulent payment. The transaction ledger can also be stored on peer-to-peer systems because the blocks include the location of the next record. No central intermediary is required. The distributed nature of blockchains makes it harder for hackers to gain access to the system. There is no one central point that is vulnerable to attack.

Composable Infrastructure

A composable infrastructure is a type of infrastructure that is pieced together conceptually, where individual elements such as compute, storage and network elements are treated as individual services. The composable infrastructure is meant to operate independently of a single hardware platform, and resource pooling helps to provide what individual elements need to perform well. The use of application programming interfaces (APIs) can help companies to create these types of infrastructures.

Radio Frequency Identification

Radio Frequency Identification (RFID) refers to technologies that use wireless communication between an object (or tag) and interrogating device (or reader) to automatically track and identify such objects. The tag transmission range is limited to several meters from the reader. A clear line of sight between the reader and tag is not necessarily required. Several industry groups, including the International Standards Organization (ISO) and International Electrotechnical Commission (IEC), regulate and define RFID interoperability standards.

Intelligent Sensor

An intelligent sensor, as the name suggests, is a sensor device that is able to perform a number of intelligent functions as part of its task or duty. An intelligent sensor is able to self-test, self-validate and self-adapt as well as self-identify. These sensors understand the environment they are put into and they can manage a wide range of conditions.

Supply Chain Risk Management (SCRM)

Supply Chain Risk Management (SCRM) is a strategic approach to lowering the probability that an organization’s reputation and/or profitability will be harmed by an untrustworthy supply chain component.

A sandbox game is also known as an open-world or free-roaming game.

Neuro Symbolic Artificial Intelligence

Neuro Symbolic Artificial Intelligence, also known as neurosymbolic AI, is an advanced version of artificial intelligence (AI) that improves how a neural network arrives at a decision by adding classical rules-based (symbolic) AI to the process. This hybrid approach requires less training data and makes it possible for humans to track how AI programming made a decision.

In image recognition, for example, Neuro Symbolic AI can use deep learning to identify a stand-alone object and then add a layer of information about the object’s properties and distinct parts by applying symbolic reasoning. This way, a Neuro Symbolic AI system is not only able to identify an object, for example, an apple, but also to explain why it detects an apple, by offering a list of the apple’s unique characteristics and properties as an explanation.

Neuro Symbolic AI is expected to help reduce machine bias by making the decision-making process a learning model goes through more transparent and explainable. Combining learning with rules-based logic is also expected to help data scientists and machine learning engineers train algorithms with less data by using neural networks to create the knowledge base that an expert system and symbolic AI requires.

Phishers use social engineering techniques to fool email recipients and Web users into believing that a spoofed email or website is legitimate and genuine. In actuality, the phishing victim later discovers their personal identity and other vital information have been stolen and exposed.

Artificial Intelligence (AI)

Artificial intelligence (AI), also known as machine intelligence, is a branch of computer science that focuses on building and managing technology that can learn to autonomously make decisions and carry out actions on behalf of a human being. AI is not a single technology. It is an umbrella term that includes any type of software or hardware component that supports machine learning, computer vision, natural language understanding (NLU) and natural language processing (NLP).

Today’s AI uses conventional CMOS hardware and the same basic algorithmic functions that drive traditional software. Future generations of AI are expected to inspire new types of brain-inspired circuits and architectures that can make data-driven decisions faster and more accurately than a human being can.

AI initiatives are often talked about in terms of their belonging to one of four categories:

Reactive AI relies on real-time data to make decisions.
Limited Memory AI relies on stored data to make decisions.
Theory of Mind AI can consider subjective elements such as user intent when making decisions.
Self-Aware AI possesses a human-like consciousness that is capable of independently setting goals and using data to decide the best way to achieve an objective.
A good way to visualize these distinctions is to imagine AI as a professional poker player. A reactive player bases all decisions on the current hand in play, while a limited memory player will consider their own and other player’s past decisions.
A Theory of Mind player factors in other player's behavioral cues and finally, a self-aware professional AI player stops to consider if playing poker to make a living is really the best use of their time and effort.

Although it was just one of many IRC clients, mIRC rapidly became the most popular, especially among gamers, who used it for decades to gather in groups and guilds. One of its most appreciated features was its ability to share files via the DCC protocol and built-in file server.

SaaS Sprawl (Software-as-a-Service Sprawl)

SaaS sprawl (Software-as-a-Service sprawl) is a phenomenon that occurs when the number of third-party cloud applications being used on a network reaches a point where administrators can no longer manage them effectively. SaaS sprawl typically occurs when project teams and individual users download and install cloud apps to meet an immediate work need without waiting for their IT department to review and approve the cloud vendor’s software product. The ease of procuring, deploying, and using software-as-a-service (SaaS) applications has made this type of shadow IT easier to deploy than ever before.

(Note also that Individuals can also use Cloud-based SaaS applications directly on the web without installing any software. This can lead to Data Loss Prevention (DLP) issues and place unauthorized business data outside of your normal operating environment or jurisdiction.)

COVID-19 work-from-home mandates inspired many business departments to allow the unsupervised use of cloud apps without stopping to consider how the apps would fit into the organization's workflows. Although the large majority of cloud apps are used in isolation, it’s still important for IT departments to manage the data that moves in and out of them.

Proof of importance (PoI) is a cryptocurrency term defined as a blockchain consensus technique – essentially, proof of importance works to prove the utility of nodes in a cryptocurrency system, so that they can create blocks.

Programming Language

A programming language is a computer language engineered to create a standard form of commands. These commands can be interpreted into a code understood by a machine. Programs are created through programming languages to control the behavior and output of a machine through accurate algorithms, similar to the human communication process. A programming language is also known as a programming system, computer language or computer system.

Functor

A functor is a type of class in C++ that acts like a function. Experts point out that a functor is created by overloading the operator and passing one argument the way that one would to a conventional function, albeit with different results.

Common Language Infrastructure

Grace Hopper

Grace Hopper was a pioneering computer scientist who helped create the field of computer programming. Hopper and her team created the first compiler, so that programmers could program with English commands. Hopper also heavily influenced the creation and standardization of COBOL, one of the first programming languages that was compatible with different computers.

Greedy Algorithm

A greedy algorithm is an algorithmic strategy that makes the best optimal choice at each small stage with the goal of this eventually leading to a globally optimum solution. This means that the algorithm picks the best solution at the moment without regard for consequences. It picks the best immediate output, but does not consider the big picture, hence it is considered greedy.

Syntax

In programming, syntax refers to the rules that specify the correct combined sequence of symbols that can be used to form a correctly structured program using a given programming language. Programmers communicate with computers through the correctly structured syntax, semantics and grammar of a programming language.

Binary Tree

A binary tree is a tree data structure where each node has up to two child nodes, creating the branches of the tree. The two children are usually called the left and right nodes. Parent nodes are nodes with children, while child nodes may include references to their parents.

Visual Basic (VB)

Visual Basic (VB) is a well-known programming language created and developed by Microsoft. VB is characterized by its simple format, which is easy to understand. Beginning programmers often consider VB the starting point in software development. VB is the visual form of BASIC, an earlier language originally developed by Dartmouth professors John Kemeny and Thomas Kurtz.

Power User

A power user is an individual that operates a computer or device with advanced skills, knowledge, experience and capabilities. A power user has the ability to reap multiple benefits and functionalities of a computer, software application or the Internet. A power user is also known as a super user.

Volatile Variable

A volatile variable is a variable that is marked or cast with the keyword "volatile" so that it is established that the variable can be changed by some outside factor, such as the operating system or other software. A volatile variable is useful in multithreaded applications or in other situations where programmers must anticipate changes to the variable other than those that are common within the code module.

Backward Chaining

Backward chaining is an inference method widely used in artificial intelligence, automated theorem provers and proof assistants. Backward chaining methodology can be described as working back from a goal. Many programming languages support backward chaining within their inference engines. Backward chaining is also referred to as backward reasoning.

Low-Level Language

A low-level language is a programming language that deals with a computer's hardware components and constraints. It has no (or only a minute level of) abstraction in reference to a computer and works to manage a computer's operational semantics. A low-level language may also be referred to as a computer’s native language.

High-Level Language (HLL)

A high-level language is any programming language that enables development of a program in a much more user-friendly programming context and is generally independent of the computer's hardware architecture. A high-level language has a higher level of abstraction from the computer, and focuses more on the programming logic rather than the underlying hardware components such as memory addressing and register utilization.

Metalanguage

From a programming language perspective, a metalanguage is a language used to make statements regarding statements made in another language, known as an object language. Metalanguage helps in describing the concepts, grammar and objects associated with a particular programming language. Metalanguage is widely used in language design, analysers, compilers and theorem provers. It is also used in financial systems, bioinformatics and in other similar applications.

Global Variable

A global variable is a programming language construct, a variable type that is declared outside any function and is accessible to all functions throughout the program. A group of global variables is called a global state or global environment because when combined, they define various aspects of a program or the environment when the program runs. A global variable is usually declared on top of all functions and is kept to a minimum, as all functions can manipulate them during the program’s run time, which is considered dangerous by most programmers because they may accidentally be changed, resulting in bugs.

IoT Solutions Architect

An IoT solutions architect is a professional role involved in developing practical uses and applications of internet of things technology. The IoT solutions architect typically works with engineers and salespeople to facilitate process development.

Hashed Table

A hashed table or hash table is a special type of internal table used in ABAP programs, where by using the hash functionality, the necessary table record is obtained. Like other types of internal tables, hashed tables are also used to extract data from standard SAP database tables by means of ABAP programs or ABAP objects. However, unlike other types of internal tables like standard or sorted, hash tables cannot be accessed using an index. As with database tables, hashed tables also require a unique key.

Low Earth Orbit (LEO)

Low earth orbit (LEO) is a designation for communication satellites whose locus extends from approximately 300 miles above the earth’s surface up to an altitude of 1,491 miles. A non-terrestrial network (NTN) of LEO satellites is called a constellation or swarm. LEO constellations can provide satellite broadband service to areas where it otherwise would be too costly or even impossible to lay land lines. LEOs, which are not fixed in space in relation to the planet's surface, are known for providing faster throughput and having less latency than traditional geostationary (GEO) satellites because they orbit over 60 times closer to the Earth's surface.

LEO orbits are typically less than 2,400 km (1,491 mi) in altitude. Geostationary (GEO) satellites orbit around the equator roughly 36,000 km (22,369 mi) above the Earth. Geosynchronous Transfer (GTO) is an elliptical orbit into which satellites are often first launched in order to reach GEO.

Fixed Wireless Access (FWA)

Blockchain (Distributed Ledger)

A blockchain is a tamper-resistant distributed ledger that's used to validate and store digital transactional records. No single authority is responsible for maintaining a Blockchain. Instead, computers in a peer-to-peer (P2P) network each store a copy of the ledger and transactions are verified through a decentralized consensus mechanism.

Transactions are stored in permanent, time-stamped units called blocks and each block is connected (chained) to the previous block with a cryptographic hash that is created by using the previous block's contents. The hash links make it impossible to alter data in one block without making changes to each subsequent block in the chain at the exact same time. Essentially, this means that any attempt to alter or delete information will break the cryptographic chain and immediately alert all nodes in the network that there is a problem.

Blockchains can be public or private. In a public blockchain, anyone can view the ledger and participate in the consensus mechanism. In a private Blockchain, the consensus mechanism is restricted to certain nodes on the network and views of the private ledger may also be restricted.

Originally created for digital currency, Blockchain is now being used by many types of businesses as a decentralized database technology to support smart contracts as well as records management for health care and identity and access management (IAM).

Internet of Behaviors (IoB)

The Internet of Behaviors (IoB) is an area of research and development (R&D) that seeks to understand how, when and why humans use technology to make purchasing decisions. IoB combines three fields of study: behavioral science, edge analytics and the Internet of Things (IoT).

IoB platforms are designed to gather, aggregate and analyze data generated from a wide variety of sources, including household digital devices, wearable computers and human online activities. The data is then analyzed in terms of behavioral psychology to look for patterns that can be used by marketing and sales teams to influence future consumer behavior.

An important goal of the IoB is to help marketers understand and monetize the massive amount of data produced by network nodes in the Internet of Things.

USB-C Connector

USB-C (Universal Serial Bus Type-C) is an industry-standard for transmitting both data and power over a single cable. The benefits of USB-C include increased data transfer rates (DTRs) and faster charging capabilities. USB-C connectors have a small rectangular shape with rounded edges. Its design is symmetrical and each end of a USB-C cable has both downstream and upstream connectors. This means that end users do not need to be concerned with orientation when plugging in a USB-C cable. USB Type-C supports the 3.2 and 3.1 versions of the USB specification. It is also backward compatible with both USB 3.0 and USB 2.0.

Predictive Maintenance

Predictive maintenance (PdM) is an approach to asset management that relies on operational data to determine when a physical asset requires service. An important goal of PdM is to minimize maintenance costs by preventing equipment failures before they occur. Predictive maintenance plays an important role in industries that requires high availability (HA) for machine parts. PdM can be contrasted with reactive maintenance and preventive maintenance.

Reactive Maintenance – Run equipment until it breaks and then fix or replace it.

Preventive Maintenance – Replace parts and schedule equipment repairs on a time- or machine-run-based schedule.

Predictive Maintenance – Use intelligent sensors to monitor machine parts in operations and machine learning to determine when data has deviated from desired parameters.

With the growth in volume as well as complexity of cyber attacks, cyber defense is essential for most entities in order to protect sensitive information as well as to safeguard assets.

Security Architecture

Security architecture is a unified security design that addresses the necessities and potential risks involved in a certain scenario or environment. It also specifies when and where to apply security controls. The design process is generally reproducible. In security architecture, the design principles are reported clearly, and in-depth security control specifications are generally documented in independent documents. System architecture can be considered a design that includes a structure and addresses the connection between the components of that structure.

Data Modeling

Data modeling is a representation of the data structures in a table for a company’s database and is a very powerful expression of the company's business requirements. This data model is the guide used by functional and technical analysts in the design and implementation of a database. Data models are used for many purposes, from high-level conceptual models to physical data models.

Predictive Model Markup Language (PMML) is an XML-based markup language designed to provide a method of defining application models related to predictive analytics and data mining. PMML attempts to eliminate proprietary issues and incompatibility from application exchange models.

Predictive Modeling

Predictive modeling is a process through which a future outcome or behavior is predicted based on the past and current data at hand.
It is a statistical analysis technique that enables the evaluation and calculation of the probability of certain results related to software, systems or an entire IT environment.

Bi-Directional Predictive Frame (B-Frame)

A bi-directional predictive frame (B-Frame) is part of an MPEG video compression standard. In this method, groups of sequential pictures are aggregated to form a group of pictures (GOP), which are displayed in sequence to provide video. A single bi-directional predictive frame relates to other frames directly preceding or following it. By recording just the information that differs from a preceding picture or a following picture, the data storage requirements for each individual picture become much lower than in a technique that would store each successive image completely. A bi-directional predictive frame may also be known as a bi-directional frame.

Predictive Analytics Tools

Predictive analytics tools provide business owners a way to predict how their customers and potential audiences are reacting to promotions and other strategies or campaigns that the businesses might be running. Predictive analytics tools work by providing well-tracked historical data and real-time insights.

Business Analytics (BA)

Business analytics (BA) refers to all the methods and techniques that are used by an organization to measure performance. Business analytics are made up of statistical methods that can be applied to a specific project, process or product. Business analytics can also be used to evaluate an entire company. Business analytics are performed in order to identify weaknesses in existing processes and highlight meaningful data that will help an organization prepare for future growth and challenges. The need for good business analytics has spurred the creation of business analytics software and enterprise platforms that mine an organization’s data in order to automate some of these measures and pick out meaningful insights.

Customer Relationship Management Analytics (CRM Analytics)

Customer relationship management analytics (CRM analytics) refers to applications used to evaluate an organization’s customer data to facilitate and streamline business choices. CRM analytics also may be used for online analytical processing (OLAP) through the use of data mining. CRM analytical tools use a variety of applications that help measure the effectiveness of customer related processes and ultimately provide customer categorization, such as profitability analysis, event monitoring, what-if scenarios and predictive modeling.

Customer Analytics

Customer analytics is an activity within of e-commerce whereby customers' online shopping and internet search behavior is examined by software with the results used by teams of marketing professionals looking to increase revenues for online merchants. Customer analytics uses data collection and subsequent software analysis to zero-in on customers' online order transactions for the purpose of sorting out specific customer demographics, shopping patterns, internet usage and applying predictive analyses to allow marketers to take measures to increase online business profit margins. Other commonly used terms for customer analytics include Customer Relationship Management analytics, or CRM analytics.

Real-Time Customer Analytics

Real-time customer analytics is a type of analytics which concentrates on real-time data captured from customers as they are performing their actions rather than on older historical data like traditional analytics, which use historical data to predict future trends. Real-time customer analytics also gives more emphasis to customer interaction and usage data rather than page views and other similar statistics, giving a more customer-centric view rather than a demographic one.

Real-Time Web Analytics

Real-time Web analytics is a technology in which the owner/manager of a website has the ability to monitor a website's users and activities in an instantaneous (or almost instant) fashion. The term encompasses all facets of a website, from visitors, pageviews, clicks, sales and other metrics, and generally implies immediate updating of dashboards and reporting.

Analytical Engine

Analytical engine most often refers to a computing machine engineered by Charles Babbage in the early 1800s. It is considered an early and very important step toward modern computer design. This term can also be used to refer to any comprehensive internal system for analytics.

Big Data Mining

Big data mining is referred to the collective data mining or extraction techniques that are performed on large sets /volume of data or the big data. Big data mining is primarily done to extract and retrieve desired information or pattern from humongous quantity of data.

Real-Time Predictive Analytics

Real-time predictive analytics is the process of extracting useful information from data sets in real time. This is done to determine and predict future outcomes. Real-time predictive analytics does not precisely predict what will happen in the future; instead, it forecasts what might happen on the basis of certain "if" scenarios.

Predictive Alerting

Predictive alerting is technology that is able to provide predictions of certain events or inputs. It is related to machine learning because the technology is able to learn from the data it is regularly processing and based on its learning, is able to make predictions which are actionable. The technology is used in many industries such as telecommunications, banking and finance, and defense.

Distributed File System

A distributed file system (DFS) is a file system with data stored on a server. The data is accessed and processed as if it was stored on the local client machine. The DFS makes it convenient to share information and files among users on a network in a controlled and authorized way. The server allows the client users to share files and store data just as if they are storing the information locally. However, the servers have full control over the data, and give access control to the clients.

Backpropagation Mean

Backpropagation is an algorithm used in artificial intelligence (AI) to fine-tune mathematical weight functions and improve the accuracy of an artificial neural network's outputs. A neural network can be thought of as a group of connected input/output (I/O) nodes. The level of accuracy each node produces is expressed as a loss function (error rate). Backpropagation calculates the mathematical gradient of a loss function with respect to the other weights in the neural network. The calculations are then used to give artificial network nodes with high error rates less weight than nodes with lower error rates.

Backpropagation uses a methodology called chain rule to improve outputs. Basically, after each forward pass through a network, the algorithm performs a backward pass to adjust the model’s weights. An important goal of backpropagation is to give data scientists insight into how changing a weight function will change loss functions and the overall behaviour of the neural network. The term is sometimes used as a synonym for "error correction."

Social Networking Site (SNS)

A social networking site is an online platform that allows users to create a public profile and interact with other users. Social networking sites usually allow a new user to provide a list of people with whom they share a connection, and then allow the people on the list to confirm or deny the connection. After connections are established, the new user can search the networks of connections to make more connections. A social networking site is also known as a social networking website or social website.

Cyclic Redundancy Check

The cyclic redundancy check (CRC) is a technique used to detect errors in digital data. As a type of checksum, the CRC produces a fixed-length data set based on the build of a file or larger data set. In terms of its use, CRC is a hash function that detects accidental changes to raw computer data commonly used in digital telecommunications networks and storage devices such as hard disk drives.

Wireless Local Area Network (WLAN)

A wireless local area network (WLAN) is a wireless distribution method for two or more devices. WLANs use high-frequency radio waves and often include an access point to the Internet. A WLAN allows users to move around the coverage area, often a home or small office, while maintaining a network connection. A WLAN is sometimes called a local area wireless network (LAWN).

File Management System

A file management system is used for file maintenance (or management) operations. It is is a type of software that manages data files in a computer system. A file management system has limited capabilities and is designed to manage individual or group files, such as special office documents and records. It may display report details, like owner, creation date, state of completion and similar features useful in an office environment. A file management system is also known as a file manager.

Data Definition Language (DDL)

A data definition language (DDL) is a computer language used to create and modify the structure of database objects in a database. These database objects include views, schemas, tables, indexes, etc. This term is also known as data description language in some contexts, as it describes the fields and records in a database table.

Database Security

Database security refers to the collective measures used to protect and secure a database or database management software from illegitimate use and malicious cyber threats and attacks. Database security procedures are aimed at protecting not just the data inside the database, but the database management system and all the applications that access it from intrusion, misuse of data, and damage. It is a broad term that includes a multitude of processes, tools and methodologies that ensure security within a database environment.

Processor

A processor is an integrated electronic circuit that performs the calculations that run a computer. A processor performs arithmetical, logical, input/output (I/O) and other basic instructions that are passed from an operating system (OS). Most other processes are dependent on the operations of a processor. The terms processor, central processing unit (CPU) and microprocessor are commonly linked as synonyms. Most people use the word “processor” interchangeably with the term “CPU” nowadays, it is technically not correct since the CPU is just one of the processors inside a personal computer (PC). The Graphics Processing Unit (GPU) is another processor, and even some hard drives are technically capable of performing some processing.

Constructor

A constructor is a special method of a class or structure in object-oriented programming that initializes a newly created object of that type. Whenever an object is created, the constructor is called automatically. A constructor is like an instance method that usually has the same name as the class, and can be used to set the values of the members of an object, either to default or to user-defined values. However, although it resembles it, a constructor is not a proper method since it doesn’t have a return type. Instead of performing a task by executing code, the constructor initializes the object, and it cannot be static, final, abstract, and synchronized.

Network Layer

The network layer is a portion of online communications that allows for the connection and transfer of data packets between different devices or networks. The network layer is the third level (Layer 3) of the Open Systems Interconnection Model (OSI Model) and the layer that provides data routing paths for network communication. Data is transferred to the receiving device in the form of packets via logical network paths in an ordered format controlled by the network layer. Logical connection setup, data forwarding, routing and delivery error reporting are the network layer’s primary responsibilities. Layer 3 can be either able to support connection-oriented or connectionless networks (but not both of them at the same time).

Macro

A macro is an automated input sequence that imitates keystrokes or mouse actions. A macro is typically used to replace a repetitive series of keyboard and mouse actions and used often in spreadsheets and word processing applications like MS Excel and MS Word. The file extension of a macro is commonly .MAC. The concept of macros is also well-known among MMORPG gamers (Massively Multiplayer Online Role-Playing Games) and SEO (Search Engine Optimization) specialists. In the world of programming, macros are programming scripts used by developers to re-use code. The term macro stands for “macro-instruction” (long instruction).

Ethereum

Ethereum is a contract management platform created by the Ethereum Foundation, a Swiss nonprofit group. It uses the digital financial ledger technology blockchain to create contracts that the foundation calls “smart contracts” that utilize blockchain to provide a static and consistent ledger record.

Broadband Wireless Access

Broadband wireless access (Wireless broadband, or WiBro) refers to inherent network mobility in a geographical area and managed mobility between fixed networks. Broadband wireless access facilitates and ensures mobile device connectivity and communication. Broadband wireless access is also known as wireless local loop (WLL), fixed-radio access (FRA), fixed wireless access (FWA), radio in the loop (RITL) and metro wireless (MW).

Public Cloud Storage

Public cloud storage is a cloud storage model that enables individuals and organizations alike to store, edit and manage data. This type of storage exists on a remote cloud server and is accessible over the internet under a subscription-based utility billing method where the users pay only for the storage capacity being used. Public cloud storage is provided by a storage service provider that hosts, manages and sources the storage infrastructure publicly to many different users. Public cloud storage service is also known as storage as a service, utility storage and online storage.

Kubernetes

Universal Serial Bus

A Universal Serial Bus (USB) is a common interface that enables communication between devices and a host controller such as a personal computer (PC) or smartphone. It connects peripheral devices such as digital cameras, mice, keyboards, printers, scanners, media devices, external hard drives and flash drives. Because of its wide variety of uses, including support for electrical power, the USB has replaced a wide range of interfaces like the parallel and serial port.

A USB is intended to enhance plug-and-play and allow hot swapping. Plug-and-play enables the operating system (OS) to spontaneously configure and discover a new peripheral device without having to restart the computer. As well, hot swapping allows removal and replacement of a new peripheral without having to reboot.

There are several types of USB connectors. In the past the majority of USB cables were one of two types, type A and type B. The USB 2.0 standard is type A; it has a flat rectangle interface that inserts into a hub or USB host which transmits data and supplies power. A keyboard or mouse are common examples of a type A USB connector. A type B USB connector is square with slanted exterior corners. It is connected to an upstream port that uses a removable cable such as a printer. The type B connector also transmits data and supplies power. Some type B connectors do not have a data connection and are used only as a power connection.

Today, newer connectors have replaced old ones, such as the Mini-USB (or Mini-B), that has been abandoned in favor of the Micro-USB and USB-C cables. Micro-USB cables are usually used for charging and data transfer between smartphones, video game controllers, and some computer peripherals. Micro-USB are being slowly replaced by type-C connectors, which are becoming the new standard for Android smartphones and tablets.

A constructor is like an instance method that usually has the same name as the class, and can be used to set the values of the members of an object, either to default or to user-defined values. However, although it resembles it, a constructor is not a proper method since it doesn’t have a return type. Instead of performing a task by executing code, the constructor initializes the object, and it cannot be static, final, abstract, and synchronized.

Internet Service Provider (ISP)

An Internet service provider (ISP) is a company that provides customers with Internet access. It is often referred to as just “the provider.” Data may be transmitted using several technologies, including dial-up, DSL, cable modem, wireless or dedicated high-speed interconnects. Typically, ISPs also provide their customers with the ability to communicate with one another by providing Internet email accounts, usually with numerous email addresses at the customer’s discretion. Other services, such as telephone and television services, or personal websites or home pages may be provided as well. The services and service combinations may be unique to each ISP.

Today, ISPs are usually cable companies or mobile phone companies that offer Internet subscriptions in addition to TV or mobile communications services. An Internet service provider is also known as an Internet access provider (IAP).

Cache Memory

Cache memory is a small-sized type of volatile computer memory that provides high-speed data access to a processor and stores frequently used computer programs, applications and data. A temporary storage of memory, cache makes data retrieving easier and more efficient. It is the fastest memory in a computer, and is typically integrated onto the motherboard and directly embedded in the processor or main random access memory (RAM).

Peripheral Device

A peripheral device is an internal or external device that connects directly to a computer or other digital device but does not contribute to the computer's primary function, such as computing. It helps end users access and use the functionalities of a computer. Since it’s not a core device for the system, the computer can still function without the peripheral, which simply provides extra functions. However, some peripherals such as a mouse, keyboard, or monitor tend to be pretty much fundamental to the interaction between the user and the computer itself. A peripheral device is also called a peripheral, computer peripheral, input-output device, or I/O device.

Mobile Application

A mobile application, most commonly referred to as an app, is a type of application software designed to run on a mobile device, such as a smartphone or tablet computer. Mobile applications frequently serve to provide users with similar services to those accessed on PCs. Apps are generally small, individual software units with limited function. This use of app software was originally popularized by Apple Inc. and its App Store, which offers thousands of applications for the iPhone, iPad and iPod Touch. A mobile application also may be known as an app, web app, online app, iPhone app or smartphone app.

Physical Layer

The physical layer is the first and lowest layer of the Open System Interconnection Model (OSI Model.) The physical layer (also known as layer 1) deals with bit-level transmission between different devices and supports electrical or mechanical interfaces connecting to the physical medium for synchronized communication. This layer plays with most of the network’s physical connections—wireless transmission, cabling, cabling standards and types, connectors and types, network interface cards, and more —as per network requirements. The physical layer does not deal with the actual physical medium (like copper, fiber, etc.)

Resolution

Resolution is a measure used to describe the sharpness and clarity of an image or picture. It is often used as a metric for judging the quality of monitors, printers, digital images and various other hardware and software technologies. The term is popular in the mobile industry for describing a mobile device's display capabilities, and also in the entertainment media to distinguish the visual quality of movies to distinguish between high definition and standard definition movies. It is also used to determine the resolution of a screen, monitor, or TV. Resolution is also referred to as screen resolution.

Production Environment

Production environment is a term used mostly by developers to describe the setting where software and other products are actually put into operation for their intended uses by end users. A production environment can be thought of as a real-time setting where programs are run and hardware setups are installed and relied on for organization or commercial daily operations.

Remote Direct Memory Access

Remote direct memory access (RDMA) is a term used in IT to describe systems that allow different networked computers to send one another data without impacting the operating system of either machine.

Secondary Storage Device

A secondary storage device refers to any non-volatile storage device that is internal or external to the computer. It can be any storage device beyond the primary storage that enables permanent data storage. A secondary storage device is also known as an auxiliary storage device, backup storage device, tier 2 storage, or external storage.

Data Redundancy

Data redundancy is a condition created within a database or data storage technology in which the same piece of data is held in two separate places. This can mean two different fields within a single database, or two different spots in multiple software environments or platforms. Whenever data is repeated, it basically constitutes data redundancy. Data redundancy can occur by accident but is also done deliberately for backup and recovery purposes.

Interpreter

An interpreter is a computer program that is used to directly execute program instructions written using one of the many high-level programming languages. The interpreter transforms the high-level program into an intermediate language that it then executes, or it could parse the high-level source code and then performs the commands directly, which is done line by line or statement by statement.

Automated Treatment Plan

An automated treatment plan is composed of a series of electronic forms and software specifically designed to help medical professionals and health care providers in treating their patients. These forms are usually customized to meet the various needs and demands of individual practitioners particularly those who are in the behavioral health care practices.

Patient data is usually captured and stored for further retrieval and report generation with relation to their corresponding medical treatment plans. An IT professional is usually needed to assist in the process of developing the automated treatment plan. On most cases, vendors and OEMs are hired to implement automated treatment plans for organizations that do not have their own IT staff.

Storage Device

A storage device is any type of computing hardware that is used for storing, porting or extracting data files and objects. Storage devices can hold and store information both temporarily and permanently. They may be internal or external to a computer, server or computing device. A storage device may also be known as a storage medium or storage media depending on whether it is seen as discrete in nature (for example, “a hard drive” versus “some hard drive space.”)

Cybercrime

Client/Server Architecture

Client/server architecture is a computing model in which multiple components work in strictly defined roles to communicate. The server hosts, delivers and manages most of the resources and services to be consumed by the client. This type of shared resources architecture has one or more client computers connected to a central server over a network or internet connection.

Client/server architecture is also known as a networking computing model or client/server network because all the requests and services are delivered over a network. It’s considered a form of distributed computing system because the components are doing their work independently of one another.

Query

Normalization

Normalization is the process of reorganizing data in a database so that it meets two basic requirements: There is no redundancy of data, all data is stored in only one place. Data dependencies are logical,all related data items are stored together. Normalization is important for many reasons, but chiefly because it allows databases to take up as little disk space as possible, resulting in increased performance. Normalization is also known as data normalization.

Data Dictionary

A data dictionary is a file or a set of files that contains a database's metadata. The data dictionary contains records about other objects in the database, such as data ownership, data relationships to other objects, and other data. The data dictionary is a crucial component of any relational database. It provides additional information about relationships between different database tables, helps to organize data in a neat and easily searchable way, and prevents data redundancy issues. Ironically, because of its importance, it is invisible to most database users. Typically, only database administrators interact with the data dictionary. A data dictionary is also called a metadata repository.

Network

A network, in computing, is a group of two or more devices or nodes that can communicate. The devices or nodes in question can be connected by physical or wireless connections. The key is that there are at least two separate components, and they are connected.

The scale of a network can range from a single pair of devices or nodes sending data back and forth, to massive data centers and even the global Internet, the largest network in existence. What all of these networks have in common, from the smallest ones to the largest, is that they allow computers and/or users to share information and resources. Networks may be used for:

Communications such as email, instant messaging, chat rooms, etc.
Shared hardware such as printers and input devices.
Shared data and information through the use of shared storage devices.
Shared software, which is achieved by running applications on remote computers.

Software Development Life Cycle (SDLC)

A software development life cycle (SDLC) model is a conceptual framework describing all activities in a software development project from planning to maintenance. This process is associated with several models, each including a variety of tasks and activities. Software development is a cumbersome activity requiring proper identification of requirements, their implementation, and software deployment. However, the activities do not end there. After the distribution of the software, proper maintenance has to be provided in a timely manner. This term is also known as the software development process model.

C++ Programming Language

C++ is an object oriented computer language created by notable computer scientist Bjorne Stroustrop as part of the evolution of the C family of languages. Some call C++ “C with classes” because it introduces object oriented programming principles, including the use of defined classes, to the C programming language framework. C++ is pronounced "see-plus-plus."

Business Intelligence Analyst (BI Analyst)

A business intelligence analyst works with data assets and data mining processes on the key concept of business intelligence or insights. Over time, as technology world evolves, there's the growing mentality that data is one of a company's biggest assets, and that by utilizing certain systems and processes, companies can glean valuable business intelligence to guide decision-making and improve business process results. A business intelligence analyst is a front-line worker in this exciting field.

Scripting Language

A scripting language is a language that uses a sophisticated method to bring codes to a runtime environment. In key ways, scripting languages are made for specific runtime environments, and they automate some of the code implementation. In that sense, they are modernizations of a system that previously used compilers to interpret inputs.

Network Identity (Network ID)

A network ID, in the world of Transmission Control Protocol/Internet Protocol or TCP/IP, is the portion of the TCP/IP address which identifies the network for a given host, usually composed of three octets with dotted decimal representation. The term “network ID” can also be applied in different ways to local network resources, for user authentication, but the classic use of the term relates to the TCP/IP address itself, how that is used to route information, and how it is used in the context of modern cybersecurity. A network ID is also known as network identification or NetID.

Amdahl's Law

Amdahl's law, named after a computer architect named Gene Amdahl and his work in the 1960s, is a law showing how much latency can be taken out of a performance task by introducing parallel computing. In parallel computing, Amdahl's law is mainly used to predict the theoretical maximum speedup for program processing using multiple processors. This term is also known as Amdahl’s argument.

Color Saturation

Color saturation refers to the intensity of color in an image. As the saturation increases, the colors appear to be more pure. As the saturation decreases, the colors appear to be more washed-out or pale. A highly saturated image has vivid, rich and bright colors, while an image with a low saturation will veer towards a scale of grey. In most monitor devices, televisions and graphic editing programs there’s an option to increase or decrease saturation. Color saturation ultimately is one of the three color properties, the other two being hue and value. Saturation is sometimes called “chroma” although the two terms have a slightly different meaning. While chroma defines the brilliance of a color in absolute terms according to the Munsell Color System, saturation is relative to pure gray. However, in nearly all instances, this difference is quite negligible in practice.

Static Method

In Java, a static method is a method that belongs to a class rather than an instance of a class. The method is accessible to every instance of a class, but methods defined in an instance are only able to be accessed by that object of a class. A static method is not part of the objects it creates but is part of a class definition. Unlike instance methods, a static method is referenced by the class name and can be invoked without creating an object of class. In simpler terms, they are methods that exist even if no object has been constructed yet and that do not require an invocation object.

Digital Video Broadcasting

Digital video broadcasting (DVB) is a standard for digital television and video that is used in many parts of the world. Various DVB standards cover satellite, cable and terrestrial television as well as video and audio coding for file formats like MPEG. Digital video broadcasting may also be referred to as digital television.

Automatic Machine Learning

Automatic machine learning (AutoML) is a general discipline that involves automating any part of the entire process of machine learning application. By working with various stages of the machine learning process, engineers develop solutions to expedite, enhance and automate parts of the machine learning pipeline. Automatic machine learning is also known as automated machine learning.

Firewall

A firewall is software or hardware that can be configured to block data from certain locations, applications, or ports while still allowing relevant and necessary data to pass through. Firewalls are used to block unauthorized access to or from networks that have different levels of trust. They work by enforcing security policies and are used to prevent malicious actors from gaining access to private networks connected to the Internet. A firewall may be implemented through hardware, software or a combination of both.

Firewalls at the perimeter of a network can be augmented by Zero Trust policies to ensure network access is granted appropriately and securely at every access layer of the OSI Model.

Microservices

A microservice is a modular software component that does one defined job. Microservices, which have become the default architecture for software development, can run as a process on an application server, virtual machines (VM) or container. Each microservice is a mini-application that has its own business logic and adapters for carrying out functions such as database access and messaging. The resulting application will have small, loosely-coupled components that communicate with each other using lightweight communication protocols. Microservices typically communicate with each other using Application Programming Interfaces (APIs).

Communication Streaming Architecture (CSA)

Communication Streaming Architecture (CSA) is a communication interface developed by Intel that links the memory controller hub (MCH) on the chipset to the network controller. The device is an individualized connection that does not use the peripheral component interconnect (PCI) bus on the input/output (I/O) controller hub. The CSA offloads network traffic from the PCI bus and reduces bottlenecks by freeing up bandwidth for other I/O processes. The CSA was only used for the Intel chipset that was manufactured in 2003. It was discontinued a year later and replaced by the PCI Express.

Computer-Mediated Communication

Computer-mediated communication (CMC) is a process in which human data interaction occurs through one or more networked telecommunication systems. A CMC interaction occurs through various types of networking technology and software, including email, Internet Relay Chat (IRC), instant messaging (IM), Usenet and mailing list servers. CMC technology saves time and money in IT organizations by facilitating the use of all communication formats.

Real Time Streaming Protocol

Real Time Streaming Protocol (RTSP) is a protocol which provides framework for real time media data transfer at the application level. The protocol focuses on connecting and controlling the multi data delivery sessions on lines of time synchronization for continuous media like video and audio. In short, real time streaming protocol acts as a network remote control for real time media files and multimedia servers. Real Time Streaming Protocol is also known as RFC 2326.

Stream Control Transmission Protocol

The Stream Control Transmission Protocol (SCTP) association is an SCTP endpoint uniquely identified by transport addresses. Only one SCTP association occurs between two endpoints at a time. The SCTP protocol is specified by RFC 4960, which updates RFC 2960 and RFC 3309.

Stream Control Transmission Protocol Endpoint

The Stream Control Transmission Protocol (SCTP) endpoint is an SCTP designated packet sender or receiver with eligible combined and unique transport addresses. SCTP endpoint addresses may not be used by other SCTP endpoints. SCTP enables single endpoint capability for multiple Internet Protocol (IP) addresses known as multi-homing. This provides better data survivability during network failure. SCTP multi-homing is only used for redundancy.

Internet Streaming Media Alliance

The Internet Streaming Media Alliance (ISMA) was a nonprofit corporation operating in the early 21st century to help standardize and explore open standards for streaming media. ISMA was a corporate collective, with participants such as Apple, Cisco and Sun Microsystems.

Deep Learning

Deep learning is a collection of algorithms used in machine learning, used to model high-level abstractions in data through the use of model architectures, which are composed of multiple nonlinear transformations. It is part of a broad family of methods used for machine learning that are based on learning representations of data.

Advance Encryption Standard

The Advanced Encryption Standard (AES) is a symmetric-key block cipher algorithm and U.S. government standard for secure and classified data encryption and decryption. In December 2001, the National Institute of Standards (NIST) approved the AES as Federal Information Processing Standards Publication (FIPS PUB) 197, which specifies application of the Rijndael algorithm to all sensitive classified data. The Advanced Encryption Standard was originally known as Rijndael.

Encryption Algorithm

An encryption algorithm is a component for electronic data transport security. Actual mathematical steps are taken and enlisted when developing algorithms for encryption purposes, and varying block ciphers are used to encrypt electronic data or numbers. Encryption algorithms help prevent data fraud, such as that perpetrated by hackers who illegally obtain electronic financial information. These algorithms are a part of any company’s risk management protocols and are often found in software applications.

Hybrid Encryption

Hybrid encryption is a mode of encryption that merges two or more encryption systems. It incorporates a combination of asymmetric and symmetric encryption to benefit from the strengths of each form of encryption. These strengths are respectively defined as speed and security. Hybrid encryption is considered a highly secure type of encryption as long as the public and private keys are fully secure.

Robotic Process Automation (RPA)

Robotic process automation (RPA) is the practice of automating routine business practices with software agents (bots) that perform tasks automatically. RPA programming plays an important role in data preprocessing and can be thought of as a more sophisticated version of macros. In the past, if an electronic form was missing a price, traditional automation software would flag the form as having an exception and issue an alert. An employee on the receiving end of the alert would then handle the exception by looking up the correct price and entering it manually on the form. With RPA technology, however, the software is able to look up the missing information and complete the form without human assistance.

Today, RPA technology is one of the fastest growing categories of enterprise application automation and sophisticated RPA bots can be taught a workflow that encompasses multiple steps, including:

Receiving forms.
Issuing a receipt for the form.
Checking the form for completeness.
Filling in missing information.
Forwarding a completed, validated form to its next destination.

Wireless Bridge

A wireless bridge is a type of networking device that enables an over-the-air connection between two different segments of a local area network (LAN). Wireless bridges use radio signals in the microwave or laser spectrum to provide fixed wireless access. A wireless bridge, which may also be referred to as a Wi-Fi bridge, works much like a wired network bridge. They play an important role in connecting LAN segments that are logically separated or located in different physical locations.

Narrow Artificial Intelligence

Narrow artificial intelligence (narrow AI) is a specific type of artificial intelligence in which a learning algorithm is designed to perform a single task, and any knowledge gained from performing that task will not automatically be applied to other tasks. Unlike general artificial intelligence, which seeks to mimic complex thought processes, narrow AI is designed to successfully complete a single task without human assistance. Popular applications for narrow AI include language translation and image recognition. Most AI applications in use today can be categorized as being narrow AI. Narrow AI may also be referred to as weak AI.

Quantum as a Service (QaaS)

Quantum as a service (QaaS) is a cloud service that provides customers with access to quantum computing platforms over the internet. QaaS uses the software as a service (SaaS) delivery model. Quantum computing is based on the qubit, which can superimpose binary positions and support artificial intelligence (AI) beyond today's narrow AI functionality. An important goal of quantum computing is to make artificial general intelligence a reality.

Although much of the theory and operational detail has been solved for quantum computing, business use for this type of computing is still very expensive. The QaaS model allows researchers to experiment with quantum computing on an on-demand basis with minimal financial output.

Cloud Application Programming Interface (Cloud API)

When a cloud provider creates an application or service, they also create APIs so that other software can communicate with that software or service.

Cloud API protocols
The protocols that support Cloud APIs include:

REST -- RESTful APIs use the HTTP protocol to perform functions such as creating, reading, updating, archiving and deleting records.

GraphQl -- GraphQL pulls all relevant data from multiple sites with a single request.

SOAP (Simple Object Access Protocol) -- SOAP APIs use the XML protocol to transfer data.

JSON-RPC -- This type of remote procedure call uses JSON formatting instead of XML to transfer data.

Data Encryption Standard

The data encryption standard (DES) is a common standard for data encryption and a form of secret key cryptography (SKC), which uses only one key for encryption and decryption. Public key cryptography (PKC) uses two keys, i.e., one for encryption and one for decryption.

Machine Learning Operations

Machine learning operations (MLOPs) is a set of practices that combines developing and maintaining machine learning (ML) seamlessly. The goal is to establish reliable communication and collaboration between data scientists and machine learning operations professionals in order to properly manage and shorten an artificial intelligence (AI) product’s lifecycle. The three main components of MLOps are machine learning, DevOps (IT), and data engineering. It achieves that by implementing automation as often as possible, settling on the balance between improving product quality and meeting business and market requirements.

MLOps works on the same principles that run DevOps. In addition to the software developers (Devs) and IT operations teams, MLOps includes data scientists and ML engineers. The result is a continuous production loop that starts with collecting data and modeling in the MLOps segment. The workflow then proceeds to the devs, where they handle the product’s verification and packaging before sending it to the IT operations team to release, configure, and monitor the result. The loop continues as the feedback is used to plan and create a new update to the machine, going back to data experts.

MLOps is able to produce noticeable results because it bridges the gap between data scientists and ML engineers, and devs and IT teams. MLOps was developed with the knowledge that not all data scientists and ML engineers are experienced in programming languages and IT operations. But instead of older models, where every section in ML development is independent, MLOps creates a continuous feedback loop between the three departments, enabling a faster development cycle and higher product quality, all whilst allowing professionals to focus solely on what they know best instead of having to learn skills on the opposite end of the spectrum.

Massively Multiplayer Online Role-Playing Game

A massively multiplayer online role-playing game (MMORPG) is a video game that takes place in a persistent state world (PSW) with thousands, or even millions, of players developing their characters in a role-playing environment. The virtual world in which the game takes place is never static. Even when a player is logged off, events are occurring across the world that may impact the player when he or she logs in again.

First Person Shooter

A first person shooter (FPS) is a genre of action video game that is played from the point of view of the protagonist. FPS games typically map the gamer's movements and provide a view of what an actual person would see and do in the game.

A FPS usually shows the protagonist's arms at the bottom of the screen, carrying whatever weapon is equipped. The gamer is expected to propel his avatar through the game by moving it forward, backward, sideways and so on using the game controller. Forward movements of the controller result in the avatar moving forward through the scenery, usually with a slight left-right rocking motion to properly simulate the human gait. In order to increase the level of realism, many games include the sounds of breathing and footsteps in addition to the regular sound effects.

FPS games can be played in two general modes, mission or quest mode and multiplayer mode. The mission mode is usually the default mode for a single player. It usually involves the player battling through progressively harder game levels towards some ultimate goal. The multiplayer mode involves multiple gamers participating via a network and playing in a shared game environment. The multiplayer mode can take many forms, including:
Deathmatches
Capture the flag
Team deathmatch
Search and destroy
Base (a.k.a assault or headquarters)
Last man standing

Grinding

Grinding refers to the playing time spent doing repetitive tasks within a game to unlock a particular game item or to build the experience needed to progress smoothly through the game. Grinding most commonly involves killing the same set of opponents over and over in order to gain experience points or gold. Although other game genres require some grinding, role-playing games (RPG) – specifically massively multiplayer online role-playing games – are the most notorious for requiring this type of time investment from players. A game level at which a lot of grinding is required may be called a treadmill level.

Emergent Gameplay

Emergent gameplay is a game design term that refers to video game mechanics that change according to the player's actions. Emergent gameplay includes a number of relatively simple decisions that a player must make, the sum of which lead to more complex outcomes. Emergent gameplay can also be created by adding multiple players to the same game environment and having their individual actions impact the overall game narrative. Similarly, more complex artificial intelligence capable of impacting the storyline in unpredictable ways can be used in lieu of additional players.

Massively Multiplayer Online Game

A massively multiplayer online game (MMOG) refers to videogames that allow a large number of players to participate simultaneously over an internet connection. These games usually take place in a shared world that the gamer can access after purchasing or installing the game software. The explosive growth in MMOGs has prompted many game designers to build online multiplayer modes into many traditionally single-player games.

Secure File Transfer Protocol

Secure File Transfer Protocol (SFTP) is a file protocol for transferring large files over the web. It builds on the File Transfer Protocol (FTP) and includes Secure Shell (SSH) security components. Secure Shell is a cryptographic component of internet security. SSH and SFTP were designed by the Internet Engineering Task Force (IETF) for greater web security. SFTP transfers files security using SSH and encrypted FTP commands to avoid password sniffing and exposing sensitive information in plain text. Since the client needs to be authenticated by the server, SFTP also protects against man-in-the-middle attacks.

SFTP can be handy in all situations where sensitive data needs to be protected. For example, trade secrets may not be covered by any particular data privacy rule, but it can be devastating for them to fall into the wrong hands. So a business user might use SFTP to transmit files containing trade secrets or other similar information. A private user may want to encrypt his or her communications as well. This term is also known as Secure Shell (SSH) File Transfer Protocol.

Cryptomining

Cryptomining is the process of validating cryptocurrency transactions. The foundation of cryptocurrencies is distributed public ledgers that record all financial transactions. The records are saved in the form of blockchains. Each transaction is linked to the subsequent transaction creating a chain of records. The records are linked using cryptographic hashes.

Because the ledger is public, a record needs to be validated before being added to the ledger. Otherwise, it would be too easy to forge fraudulent payments. Cryptocurrencies use Proof-of-Work (PoW) as a security measure.

In order to post a transaction to the ledger, a problem that is difficult to solve, but easy to verify must be computed. The problems are computationally complex and require brute force to solve. A network of computers will compete to solve the problem first. This process is called cryptomining.

The computer that solves the problem first earns the right to post the transaction to the ledger. The goal is to make the cost of solving the complex problem higher than the gain of posting a fraudulent transaction. The benefit to the cryptominer is that for every transaction posted, the winner receives a small reward. The reward is often a combination of a fee associated with the transaction and newly created cryptocurrency.

Integrated Services Digital Network (ISDN)

Integrated Services Digital Network (ISDN) is a set of communication standards for digital telephone connection and the transmission of voice and data over a digital line, and is a development of the plain old telephone service (POTS). These digital lines are commonly telephone lines and exchanges established by the government. They are used instead of the traditional circuits of the classic switched telephone network since they can integrate data and speech on the same line. Before ISDN, it was not possible for ordinary telephone lines to provide fast transmission over a single line.

ISDN was designed to run on digital telephone systems that were already in place. As such, it meets telecom’s digital voice network specifications. Originally, it was largely used by businesses that needed to support many desk phones and fax machines. However, it took so long for ISDN to be standardized that it was never fully deployed in the telecommunications networks it was intended for.

ISDN was formally standardized in 1988 and gained some significant popularity in the 1990s as a faster (128 Kbps) alternative to the 56 Kbps dial-up connection for internet access. However, as soon as telecom companies switched from analog to digital infrastructures, modern long-distance networking and broadband internet technologies eventually made it an obsolete technology.

Deep Learning

Deep learning is currently the most sophisticated AI architecture in use today. Popular deep learning algorithms include:

Recurrent neural networks - the algorithm is able to remember sequential data. Used for speech recognition, voice recognition, time series prediction and natural language processing.

Long short-term memory networks - the algorithm can learn order dependence in sequence prediction problems. Used in machine translation and language modeling.

Generative adversarial networks - two algorithms compete against each other and use each other's mistakes as new training data. Used in digital photo restoration and deepfake video.

FileMaker Pro

FileMaker Pro is a cross-platform relational database application that is currently being marketed as a low-code/no-code (LCNC) database management system (DBMS) and rapid application development (RAD) software development tool. Data can be easily exported and imported to and from FileMaker Pro, and the graphical user interface (GUI) is designed to help non-technical line of business (LOB) professionals easily search, filter and sort specific data sets.

Each file in a FileMaker Pro database can consist of multiple tables, layouts, fields, menu sets, scripts, functions, logical relationships, calculations and embedded multimedia objects. Data in one table can be linked to data in other tables and multiple views for each table can easily be created, saved and shared. In the technology marketplace, FileMaker's competitors include MySQL, Libre Office Space and Zoho. It's possible to connect FileMaker to these other database systems by using a RESTful API called Claris Connect.

Firmware

Firmware is a type of software that is etched directly into a piece of hardware. It operates without going through APIs, the operating system, or device drivers—providing the needed instructions and guidance for the device to communicate with other devices or perform a set of basic tasks and functions as intended. Without firmware, the most basic of devices would not function. That is why it is often stored on a Read-Only Memory (ROM) chip, ensuring it does not get erased by accident, all while remaining as close as possible to the metal of the device.

Firmware comes in various complexities and can be found in simple devices, like keyboards and hard drives, to more complex ones, like graphics cards and Basic Input/Output System (BIOS). In Android operating systems, the firmware is different depending on the manufacture, that is, it is the operating software is device-specific. When a device is powered on, firmware is the first part to run and starts sending instructions to the device's processor to execute. If the device is as simple as a keyboard, the firmware does not stop working as there is no software to replace it. However, in more complex devices, such as PCs, laptops, and tablets, there are often multiple firmware sets that interact to achieve a common goal; load the operating system.

Regardless of the type of device, firmware can only work with a basic or low level, binary language known as machine language. While the firmware's code could be written in a high level language for ease and versatility, it needs to be translated into a low level language before getting etched into the device. The same firmware cannot run on processors it was not designed for, as different processors can only identify certain instructions. If a device’s firmware were to get corrupted—during an update, for example—it cannot be fixed, as there is no way to communicate with the machine to install a replacement.

Hyperautomation

Hyperautomation is a strategic approach to scaling automation within an enterprise. The strategy involves identifying what tasks to automate and choosing the most appropriate automation tools for each task. An important goal of hyperautomation is to optimize ways that robotic process automation (RPA) can be used to improve productivity. Gartner and some big companies in the tech space are promoting hyperautomation as the next wave of automation or “automation 2.0.”

Hyperparameter

A hyperparameter is a machine learning parameter whose value is chosen before a learning algorithm is trained.

Hyperparameters should not be confused with parameters . In machine learning, the label parameter is used to identify variables whose values are learned during training. The prefix hyper is used to identify higher-level parameters that control the learning process.

Every variable that an AI engineer or ML engineer chooses before model training begins can be referred to as a hyperparameter -- as long as the value of the variable remains the same when training ends.

It’s important to choose the right hyperparameters before training begins because this type of variable has a direct impact on the performance of the resulting machine learning model. Examples of hyperparameters in machine learning include:

Model architecture
Learning rate
Number of epochs
Number of branches in a decision tree
Number of clusters in a clustering algorithm

Robotic Process Automation (RPA)

Robotic process automation (RPA) is a technology that uses software agents (bots) to carry out routine clerical tasks without human assistance. RPA is useful for automating business processes that are rules-based and repetitive.

RPA bots can follow a workflow that encompasses multiple steps across multiple applications. Unlike traditional automation projects that require extensive developer help, RPA projects simply use an organization's existing applications.

Essentially, RPA can be thought of as a more sophisticated version of macros. Initially, the technology requires a human to record themselves carrying out a specific business process. This creates a script that a bot uses to replicate workflow.

RPA is often used for data preprocessing tasks, including data entry, data reconciliation and spreadsheet manipulation. Additional uses at the enterprise-level include data analytics, data reporting and event-driven customer outreach.

Popular commercial off-the-shelf (COTs) RPA tools include Blue Prism, Automation Anywhere and UiPath.

Synthetic Data

Synthetic data is input that is generated mathematically from a statistical model. Synthetic data plays an important role in finance, healthcare and artificial intelligence (AI) when it is used to protect personally identifiable information (PII) in raw data and fabricate massive amounts of new data to train machine learning (ML) algorithms.

Synthetic data is created by executing sequential statistical regression models against each variable in a real-world data source. Any new data collected from the regression models will statistically have the same properties as the originating data, but its values will not correspond to a specific record, person or device.

Synthetic data provides data scientists and analysts with quick access to additional data and frees them from having to worry about compliance. Its varied uses include:

Machine learning (ML) -- synthetic data can be used to quickly create additional data that statistically resembles the originating raw data.
Analytics -- synthetic data can be used to build large datasets by extrapolating information from relatively small datasets.
Compliance -- synthetic data can be used to provide data privacy by de-coupling the information a record contains from its originating source.
Information security -- synthetic data can be used to populate honeypots with fabricated data that's realistic enough to attract attackers.
Software development -- synthetic data can be used in quality assurance (QA) to test code changes in a sandbox environment.

Transport Layer

The transport layer is the fourth layer in the open systems interconnection (OSI) network model. The OSI model divides the tasks involved with moving information between networked computers into seven smaller, more manageable task groups. Each of the seven OSI layers is assigned a task or group of tasks.

The transport layer's tasks include error correction as well as segmenting and desegmenting data before and after it's transported across the network. This layer is also responsible for flow control and making sure that segmented data is delivered over the network in the correct sequence. Layer 4 (the transport layer) uses the transmission control protocol (TCP) & user data protocol (UDP) to carry out its tasks.

Overfitting

Overfitting is a condition that occurs when a machine learning or deep neural network model performs significantly better for training data than it does for new data. Overfitting is the result of an ML model placing importance on relatively unimportant information in the training data. When an ML model has been overfit, it can't make accurate predictions about new data because it can't distinguish extraneous (noisey) data from essential data that forms a pattern.

For example, if a computer vision (CV) program's task is to capture license plates, but the training data only contains images of cars and trucks, the learning model might overfit and conclude that having four wheels is a distinguishing characteristic of license plates. When this happens, the CV programming is likely to do a good job capturing license plates on vans, but fail to capture license plates on motorcycles.

The most common causes of overfitting include the following:

The data used to train the model is dirty and contains large amounts of noise.
The model has a high variance with data points that are very spread out from the statistical mean and from each other.
The size of the training dataset is too small.
The model was created by using a subset of data that does not accurately represent the entire data set.

Computer Vision

Computer vision (CV) is the subcategory of artificial intelligence (AI) that focuses on building and using digital systems to process, analyze and interpret visual data. The goal of computer vision is to enable computing devices to correctly identify an object or person in a digital image and take appropriate action.

Computer vision uses convolutional neural networks (CNNs) to processes visual data at the pixel level and deep learning recurrent neural network (RNNs) to understand how one pixel relates to another.

Uses for computer vision include:

Biometric access management -- CV plays an important role in both facial and iris recognition.
Industrial robots and self-driving cars -- CV allows robots and autonomous vehicles to avoid collisions and navigate safely.
Digital diagnostics -- CV can be used in tandem with other types of artificial intelligence programming to automate the analysis of X-rays and MRIs.
Augmented reality -- CV allows mixed reality programming to know where a virtual object should be placed.

Personally Identifiable Information (PII)

Personal Identifiable Information (PII) is a label used to describe data that directly or indirectly identifies a specific individual.

Examples of PII include names, addresses, biometrics and alphanumeric account numbers.

Name -- includes full names, maiden names, mother‘s maiden names, nicknames and aliases.
Address -- includes street addresses, email addresses, IP addresses and MAC addresses.
Biometrics -- includes photographs, x-rays and other types of bio-based data such as fingerprints.
Alphanumeric account numbers -- includes telephone numbers, driver‘s license numbers, taxpayer IDs, patient IDs, vehicle registration numbers and credit card numbers.
In many parts of the world, personally identifiable data has to be collected, stored and destroyed in accordance with compliance rules and regulations. Because non-PII can easily become PII if additional information is made publicly available, this type of data should be periodically reviewed to determine whether its IT risk management level has changed.

Risk impact levels (low, medium, high) for PII are subjective and based on the potential harm that inappropriate access, use or disclosure of the personally identifiable information would cause. The likelihood of risk is greatly reduced if an organization minimizes the amount of PII it collects, stores and shares.

Logistic Regression

Logistic regression is a supervised learning algorithm used in machine learning to predict the probability of a binary outcome. A binary outcome is limited to one of two possible outcomes. Examples include yes/no, 0/1 and true/false. Logical regression is used predictive modeling to analyze large datasets in which one or more independent variables can determine an outcome. The outcome is expressed as a dichotomous variable that has one of two possible outcomes. Essentially, logistic regression works by estimating the mathematical probability that an instance belongs to a specified class -- or not.

DevRel (DeveloperRelations)

Developer Relations (DevRel) is a strategic approach to improving business-to-business (B2B) communications between a software company’s internal programmers and the external programmers who will be using the company’s open APIs. Just as DevOps strives to improve communication between an organization’s developer and operations teams, DevRel seeks to improve communication between proprietary and open-source developer communities.

Typically, a DevRel team is made up of employees from the software company's product, engineering and marketing teams. In addition to serving as developer evangelists, team members are responsible for gathering metrics that can be used to quantify user engagement and help the software company's internal developers understand their end users' pain points.

Artificial Intelligence Engineer

An artificial intelligence engineer is someone whose job is to identify the right approach to using AI to solve a specific business problem. In the enterprise, AI engineers typically work closely with machine learning engineers to develop and deploy learning algorithms that can use historical and real-time data to predict future events. In smaller companies, the same person (AI/ML engineer) may be responsible for both AI strategy and implementation.

AI engineers need a strong background in math and statistics. Ideally, they are also familiar with Python and R, as well as their most commonly-used libraries and packages. Basic responsibilities for an AI engineer include the following:

Establish business objectives for implementing AI.
Brainstorm with other IT team members to explore how machine learning concepts can be used solve specific business problems.
Develop proof of concepts (POCs).
Identify obstacles that could potentially put an AI-driven project at risk and research workarounds.
Create metrics to measure an AI project’s return on investment (ROI).
Promote best practices for data wrangling, data processing and project documentation

Machine Intelligence

Machine intelligence is an umbrella term that's used to describe the accuracy of a machine learning (ML), deep learning (DL) or classical algorithm output.

In business-to-business (B2B) marketing, the term is also being used to describe a growing market segment for information technology (IT) vendors who specialize in machine learning and artificial intelligence as a service (MLaaS and AIaaS).

Data Wrangling

Data wrangling is a process that data scientists and data engineers use to locate new data sources and convert the acquired information from its raw data format to one that is compatible with automated and semi-automated analytics tools. Data wrangling, which is sometimes referred to as data munging, is arguably the most time-consuming and tedious aspect of data analytics.

The exact tasks required in data wrangling depend on what transformations the analyst requires to make a dataset useable. The basic steps involved in data wranging include:

Discovery -- learn what information is contained in a data source and decide if the information has value.
Structuring -- standardize the data format for disparate types of data so it can be used for downstream processes.
Cleaning -- remove incomplete and redundant data that could skew analysis.
Enriching -- decide if you have enough data or need to seek out additional internal and/or 3rd-party sources.
Validating -- conduct tests to expose data quality and consistency issues.
Publishing -- make wrangled data available to stakeholders in downstream projects.

In the past, wrangling required the analyst to have a strong background in scripting languages such as Python or R. Today, an increasing number of data wrangling tools use machine learning (ML) algorithms to carry out wrangling tasks with very little human intervention.

Digital Twin
A digital twin is a digital version of an entity or system that exists in the physical world. They allow users to learn how a change will impact a physical object or system by testing the change first on a virtual model.

Digital twins can be either static or dynamic. Static twins, which are also referred to as simulations, represent an entity or system at a specific point in time. Dynamic twins are linked to the physical entity or system they represent in order to accurately depict the state of the entity or system in real time.

Digital twins play an important role in research and development (R&D), system integration, change management and enterprise risk management. Popular uses for digital twins include:

Forecasting the health of an entity or system under specific conditions.
Training staff how to use/manage a physical entity or system.
Capturing requirements for a new entity or sytem.
Predicting how a change will affect a real-world entity or system.
Comparing two different lifecycle plans for an entity or system.
Understanding an entity or system's dependencies prior to building it in the real world.

Data Purging
Data purging is the process of permanently removing obsolete data from a specific storage location when it is no longer required.

Common criteria for data purges include the advanced age of the data or the type of data in question. When a copy of the purged data is saved in another storage location, the copy is referred to as an archive.

The purging process allows an administrator to permanently remove data from its primary storage location, yet still retrieve and restore the data from the archive copy should there ever be a need. In contrast, the delete process also removes data permanently from a storage location, but doesn’t keep a backup.

In enterprise IT, the compound term purging and archiving is used to describe the removal of large amounts of data, while the term delete is used to refer to the permanent removal of small, insignificant amounts of data. In this context, the term deletion is often associated with data quality and data hygiene, whereas the term purging is associated with freeing up storage space for other uses.

Strategies for data purging are often based on specific industry and legal requirements. When carried out automatically through business rules, purging policies can help an organization run more efficiently and reduce the total cost of data storage both on-premises and in the cloud.

Graphics Processing Unit (GPU)
A graphics processing unit (GPU) is a parallel processor that allows repetitive calculations within an application to run simultaneously. GPUs were introduced towards the end of the last century to help central processing units (CPUs) keep up with the huge number of calculations required by animated video games. The GPU carried out repetitive calculations concurrently, while the rest of the application continued to run on the CPU.

As the demand for graphic applications increased towards the end of the last century, GPUs became more popular. Eventually, they became not just an enhancement but a necessity for optimum performance of a PC. Today, GPUs are powerful enough to perform rapid mathematical calculations in parallel for deep learning algorithms and are used in just about every type of computing device, including mobile phones, tablets, display adapters, workstations and game consoles.
