In computing, a computer keyboard is a typewriter-style device which
uses an arrangement of buttons or keys to act as a mechanical lever or electronic switch.
A keyboard typically has characters engraved or printed on the keys and each press of a key typically corresponds to a single written symbol.
In normal usage, the keyboard is used as a text entry interface to type text and numbers into a word processor, text editor or other programs.
