Keyboard (computing) - In computing, a keyboard is an input device partially modelled after the typewriter keyboard which uses an arrangement of buttons, or keys which act as electronic switches.

A keyboard layout is any specific mechanical, visual, or functional arrangement of the keys, legends, or key–meaning associations (respectively) of a computer, typewriter, or other typographic keyboard.
