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. 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. Personal computer (pc), a digital computer designed for use by only one person at a time. 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.
Printers are a common example of output devices New multifunction peripherals that integrate printing, scanning, and copying into a single device are also popular Computer monitors are sometimes treated as peripherals.
