Arrays of keys or buttons used to input information into computers or to play musical instruments. The primary interface between humans and digital devices.
Compound of 'key' + 'board', first used for musical instruments in the 1820s, then adopted for typewriters and later computers. The concept transfers the physical action of pressing keys to generate symbols or sounds.
Keyboards represent one of humanity's most successful interface designs - the same basic layout we use for typing was designed for typewriters in the 1870s and remains virtually unchanged despite radical technological evolution. They're essentially the bridge between human thoughts and digital expression.
