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.
Before Babbage there is no evidence that anyone had ever conceived of such a device, let alone attempted to build one. The machine was designed to consist of four components: the mill, the store, the reader, and the printer. These components are the essential components of every computer today.
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 science is the study of computers and computing, including their theoretical and algorithmic foundations, hardware and software, and their uses for processing information.
The physical elements of a computer, its hardware, are generally divided into the central processing unit (CPU), main memory (or random-access memory, RAM), and peripherals.
A computer programming language is any of various languages for expressing a set of detailed instructions for a computer. The earliest programming languages were assembly languages, not far removed from instructions directly executed by hardware.
