Computer Science

Information technology (IT) is the use of any computers, storage, networking and other physical devices, infrastructure and processes to create, process, store, secure and exchange all forms of electronic data.

A server is a computer program or device that provides a service to another computer program and its user, also known as the client.

Software is a set of instructions, data or programs used to operate computers and execute specific tasks.

A logic gate is an elementary building block of a digital circuit. There are seven basic logic gates: AND, OR, XOR, NOT, NAND, NOR, and XNOR.

RFID tagging uses small radio frequency identification devices to track and identify objects.

A delivery drone is a type of unmanned aerial vehicle (UAV) used for distributing packages to consumers through advanced AI technology.

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.

RIP (Routing Information Protocol) is a protocol used to enable routers to share information about IP traffic routes as they move traffic within a larger network made up of separate LANs linked through routers.

Alphanumeric, also referred to as alphameric, is a term that encompasses all of the letters and numerals in a given language set.

Calculating the mean, median, mode and range of a set of numbers allows you to track changes over time and set acceptable ranges and variance. Here's how to find your data's mean, median, mode or range, and what it tells you.

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

How to select the right firewall for your needs

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

Data analytics (DA) is the science of examining raw data with the purpose of drawing conclusions about that information.

Binomial distribution is a type of formula in mathematics and statistics for predicting probabilities where there are two possible outcomes over a set of instances.

Hysteresis is the tendency for a system to change or react based on a trend of how it has already transformed leading up to a specific point in time.

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).

A smart card is a physical card that has an embedded integrated chip that acts as a security token.

A neuromorphic chip is an analog data processor inspired by the biological brain.

Quantum as a service (QaaS) is the offering of quantum compute facilities as an on demand service.

Bionics is the replication of biological systems by mechanical and electronic systems. Physician and researcher Jack Steele coined the term bionics in 1958 to describe the study of biological organisms to solve engineering problems.

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

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...)

RIP (Routing Information Protocol) is a protocol used to enable routers to share information about IP traffic routes as they move traffic within a larger network made up of separate LANs linked through routers.

TCP/IP, or the Transmission Control Protocol/Internet Protocol, is a suite of communication protocols used to interconnect network devices on the internet. TCP/IP can also be used as a communications protocol in a private network (an intranet or an extranet).

A network protocol is a set of established rules that dictates how to format, transmit and receive data so computer network devices -- from servers and routers to endpoints -- can communicate regardless of the differences in their underlying infrastructures, designs or standards.

A chatbot (sometimes referred to as a chatterbot) is a computer program that attempts to simulate the conversation or "chatter" of a human being via text or voice interactions.

A delivery drone is a type of unmanned aerial vehicle (UAV) used for distributing packages to consumers through advanced AI technology.

Drone services, also known as unmanned aerial vehicle (UAV) services, is the emerging market for services built around flying robots that can be remote-controlled or flown autonomously using software-controlled flight plans in their embedded systems.

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.
