A computer is a programmable device for processing, storing, and displaying information. Learn more in this article about modern digital electronic computers and their design, constituent parts, and applications as well as about the history of computing.
A computer is a machine that can store and process information. Most computers rely on a binary system, which uses two variables, 0 and 1, to complete tasks such as storing data, calculating algorithms, and displaying information.
Computer, device for processing, storing, and displaying information. Computer once meant a person who did computations, but now the term almost universally refers to automated electronic machinery.
Computer - History, Technology, Innovation: A computer might be described with deceptive simplicity as “an apparatus that performs routine calculations automatically.”
Computer - Technology, Invention, History: By the second decade of the 19th century, a number of ideas necessary for the invention of the computer were in the air.
Computer science is the study of computers and computing, including their theoretical and algorithmic foundations, hardware and software, and their uses for processing information.
Computer art, manipulation of computer-generated images (pictures, designs, scenery, portraits, etc.) as part of a purposeful creative process. Specialized software is used together with interactive devices such as digital cameras, optical scanners, styli, and electronic tablets.
Computer software is divided into two basic types—the operating system and application software. The operating system controls how the different parts of hardware work together. Application software gives the computer instructions for doing specific tasks, such as word processing or playing games.
Malware (a portmanteau of the terms malicious and software) consists of computer viruses, spyware, computer worms, and other software capable of stealing devices’ data or running harmful code.
