Computer Science

A cache -- pronounced CASH -- is hardware or software that is used to store something, usually data, temporarily in a computing environment.

A laser is a coherent and focused beam of photons; coherent, in this context, means that it is all one wavelength, unlike ordinary light which showers on us in many wavelengths.

A mebibyte (MiB) is a unit of measurement used in computer data storage.

Electromagnetic induction is the creation of an electro-motive force by way of a moving magnetic field around an electric conductor and, conversely, the creation of current by moving an electric conductor through a static magnetic field.

A laser is a coherent and focused beam of photons; coherent, in this context, means that it is all one wavelength, unlike ordinary light which showers on us in many wavelengths.

Apple HomePod is the company’s Wi-Fi connected smart speaker that supports multi-room setups.

A motor vehicle record (MVR) is the documentation of a person’s driving history. The information in an MVR includes personally identifiable information (PII) as well as information about the driver's traffic citations, vehicular crimes, accidents, driving under the influence (DUI) convictions and the number of points on the individual’s driver’s license.

United States Department of Energy (DOE) is a federal cabinet agency that is tasked with overseeing the energy economy, energy policies and energy security of the U.S. The agency creates policies for nuclear power, fossil fuel and alternative energy sources.

The Cloud Security Alliance (CSA) is a nonprofit organization that promotes research into best practices for securing cloud computing and the use of cloud technologies to secure other forms of computing.

LTO (Linear Tape-Open) tape is an open-format tape storage technology created by Hewlett-Packard (HP), International Business Machines (IBM) and Seagate Technology.

The Sarbanes-Oxley Act of 2002 is a federal law that established sweeping auditing and financial regulations for public companies.

Grid computing (or the use of a computational grid) is applying the resources of many computers in a network to a single problem at the same time

Quick Network Security & Hardware Refreshers School is out for college students across the US, but the learning never stops for IT professionals.

In mathematics, combination and permutation are two different ways of grouping elements of a set into subsets. In a combination, the elements of the subset can be listed in any order. In a permutation, the elements of the subset are listed in a specific order.

Kinematics is the study of the motion of mechanical points, bodies and systems without consideration of their associated physical properties and the forces acting on them.

Random walk hypothesis is a mathematical theory where a variable does not follow an apparent trend and moves seemingly at random.

Cache memory, also called CPU memory, is high-speed static random access memory (SRAM) that a computer microprocessor can access more quickly than it can access regular random access memory (RAM).

An AI accelerator is a microchip designed specifically to enable faster processing of artificial intelligence (AI) tasks.

The Intel Xeon D-2100 processor is a system on a chip (SoC) designed with low power requirements for computing data at the device-level of Internet of Things (IoT) and smart devices.

A digital pill is a capsule with embedded sensors that send healthcare-related data to external parties.

A smart machine is a device embedded with machine-to-machine (M2M) and/or cognitive computing technologies such as artificial intelligence (AI), machine learning or deep learning, all of which it uses to reason, problem-solve, make decisions and even, ultimately, take action.

Superposition is the ability of a quantum system to be in multiple states at the same time until it is measured.

In the SearchVoIP.com videocast, Whatis.com's Alex Howard discusses the differences between unified messaging and unified communications, the features each option allows users and the development of UM to UC. Whether you are considering UC or have already implemented unified communications, this videocast embedded on the right explains the differences between the technologies and how UC will continue to impact the future of communications.

In this WhatIs.com podcast, you'll learn about this attempt to modernize existing banking practices in the context of new online threats like phishing. To learn more about FFIEC compliance, Assistant Site Editor Alex Howard interviewed Patrick Audley, the CTO of risk adaptive software provider Cogneto.

In this podcast you will learn what service-oriented architecture (SOA) is, how it relates to other programming approaches and what standards and tools you need to be aware of before implementing SOA. (Continued...)

IPsec, also known as the Internet Protocol Security or IP Security protocol, defines the architecture for security services for IP network traffic.

Multiprotocol Label Switching (MPLS) is a protocol-agnostic routing technique designed to speed up and shape traffic flows across enterprise wide area and service provider networks.

The data link layer is the protocol layer in a program that handles the moving of data into and out of a physical link in a network.

Cognitive computing systems use computerized models to simulate the human cognition process to find solutions in complex situations where the answers may be ambiguous and uncertain.

A collaborative robot, also known as a cobot, is a robot that is capable of learning multiple tasks so it can assist human beings.

VR locomotion is technology that enables movement from one place to another (locomotion) within a virtual reality environment. Locomotion through a virtual environment is enabled by a variety of methods including head bobbing and arm swinging, as well as other natural movements that translate to in-game movements.

Videogrammetry is the extraction of an object’s measurements from a video; measurements may be gathered from multiple angles or multiple videos.

A digital evidence presentation system (DEPS) is a system with an overhead camera and a liquid crystal display (LCD) used in courts to present and record evidence digitally.

A video display unit (VDU) consists of:A computer output device that uses a cathode ray tube or other technology to present visual imagesOne or more input devices, such as a keyboard, a mouse, or both.
