A computer keyboard is a typewriter-style input device that uses an arrangement of buttons or keys that act as electronic switches.[1]
Keyboard keys (buttons) typically have a set of characters engraved or printed on them, and each press of a key (or combination of keys) typically corresponds to a single written symbol or or other interrupt request.[2] While most keyboard keys produce letters, numbers or symbols (characters), other keys or simultaneous key presses can prompt the computer to execute system commands, such as such as the Control-Alt-Delete combination used with Microsoft Windows.[3][4] In a modern computer, the interpretation of key presses is generally left to the software: the information sent to the computer, the scan code, tells it only which key (or keys) on which row and column, was pressed or released.[5]
In normal usage, the keyboard is used as a text entry interface for typing text, numbers, and symbols into application software such as a word processor, web browser or social media app.
Although a keyboard is a hardware device, it is modelled in software in the computer.
