Computer Meaning and Definition in Wikipedia


A computer is a machine (mostly electronic) that is able to take information (input), do some work on or make changes to the information (process), to make new information (output). Computers have existed for much of human history. Examples of early computers are the astrolabe and the abacus. There are four main processing steps in a computer, and they are: inputting, outputting, storage and processing.

Modern computers are very different from early computers. They can do billions of calculations per second. Most people have used a personal computer in their home or at work. Computers do many different jobs where automation is useful. Some examples are controlling traffic lights, vehicle computers, security systems, washing machines and digital televisions.

A computer user can control it by a user interface. Input devices include keyboard, mouse, buttons, touch screen. Some very new computers can also be controlled with voice commands or hand gestures or even brain signals through electrodes implanted in the brain or along nerves.
