Computer scientist

A computer scientist is a researcher who develops theories, models, and solutions to fundamental computer and information science problems, typically holding a master's degree or PhD.

Computer security

Computer security, also called IT security or digital security, is the protection of computer systems and the information they hold from unauthorized access, disruption, modification, or destruction.

Computer terminal

A computer terminal, also called a video terminal or glass teletype, is a keyboard and screen or printer for interacting with a distant computer, key to time-sharing.

Computer virus

A computer virus, a term now often used for malware generally, is malicious software that copies itself into other programs and runs when the host program is invoked.

Computer vision

Computer vision is the field of computing concerned with visual perception by computers, extracting information from images and video to recognize objects and reconstruct scenes.

Computer vision dazzle

Computer vision dazzle, also called CV Dazzle or anti-surveillance makeup, is bold makeup and hairstyling created by artist Adam Harvey in 2010 to defeat face detection and facial recognition software.

Computer worm

A computer worm, also called a network worm, is self-contained malware that copies itself across computer networks without a host program, often without user intervention, as the 1988 Morris worm first showed.

Computer-aided design

Computer-aided design (CAD) is the use of computer software to create, modify, and document 2D drawings and 3D models of parts and buildings, supporting engineering design since around 1960.

Computer-aided dispatch

Computer-aided dispatch (CAD) is a real-time software system that emergency communications centers use to receive, prioritize, and route 911 calls and assign and track responding units; St. Louis police pioneered it in 1965.

Computer-aided engineering

Computer-aided engineering (CAE) is the use of software to simulate product performance, covering structural, thermal, fluid, electromagnetic, and acoustic analysis, so engineering decisions come from mathematical models before physical testing.

Computer-aided manufacturing

Computer-aided manufacturing (CAM), also written computer-assisted manufacturing, uses computer systems to plan, manage, and control plant operations, typically converting CAD designs into G-Code for CNC machines.

Computer-aided process planning

Computer-aided process planning (CAPP) is a manufacturing engineering method that uses software to convert a CAD model into operation sequences and routings, treated as the bridge between CAD and CAM.

Computer-assisted translation

Computer-assisted translation (CAT), also called machine-aided translation, uses software like translation memories and termbases to help a human translator, who reviews and decides on the final translation.

Computer-generated imagery

Computer-generated imagery (CGI), also known as computer imagery, creates still or animated visual content with imaging software, spanning 3D modeling, animation, and rendering in film and games.

Computer-integrated manufacturing

Computer-integrated manufacturing (CIM), a term coined by Joseph Harrington in 1973, uses networked computers and a common database to coordinate all phases of manufacturing, from design to quality control.

Computer-use agents

A computer-use agent is software that operates a computer's graphical interface for a user, reading screenshots with a vision-language model and issuing clicks, keystrokes, and scrolls.

Computing

Computing is the use of machines and organized procedures to process information automatically, and the engineering discipline designing the hardware, software, and systems that do it.

Computing Curricula 2001

Computing Curricula 2001 (CC2001) is an undergraduate computer science curriculum report published in 2001 by the ACM and IEEE Computer Society, the first focused solely on computer science.

Computing platform

A computing platform, also called a computer platform, is the environment on which software is installed and run, such as hardware with an operating system or a virtual machine.

Computing with words

Computing with words (CWW) is a fuzzy-logic methodology, introduced by Lotfi Zadeh in 1996, in which words rather than numbers are computed and reasoned with.

Compuware

Compuware was an American software company headquartered in Detroit, founded in 1973, best known for mainframe development, testing, and performance tools until BMC acquired it in 2020.

COMSOL Multiphysics

COMSOL Multiphysics, first released as FEMLAB in 1998, is a commercial finite element simulation environment for modeling coupled physics, the flagship product of the Swedish company COMSOL.

Comstar (satellite)

Comstar was a series of four American geostationary domestic communications satellites built by Hughes Aircraft for Comsat General, launched from Cape Canaveral between 1976 and 1981.

Con Air

Con Air is a 1997 American action film directed by Simon West, in which hijacking prisoners on a prison transport plane are opposed by a paroled Army Ranger.

Conagra Brands

Conagra Brands, formerly ConAgra Foods, is an American packaged-food company headquartered in Chicago whose brands include Birds Eye, Slim Jim, Duncan Hines, and Healthy Choice.

Concealed carry

Concealed carry is the practice of carrying a hidden handgun or other weapon in public, in most US states with no permit required and elsewhere under a state permit.

Concentrated electrolyte

A concentrated electrolyte is a battery electrolyte with salt so concentrated that anions join the solvation shell, changing interfacial chemistry and enabling higher-voltage lithium and sodium batteries.

Concentrated solar power

Concentrated solar power, also called concentrating solar-thermal power, uses mirrors to focus sunlight onto a receiver, heating a fluid that drives a turbine; molten salt storage lets plants generate after sunset.

Concentrated winding

A concentrated winding is a stator winding for electrical machines in which each non-overlapping coil is wound around a single stator tooth, also called a fractional-slot or tooth-coil winding.

Concentration polarization

Concentration polarization is the buildup of rejected solute in a boundary layer at a membrane surface, lowering water flux and increasing solute leakage in membrane separations.
