Keyboard
A Keyboard (pronounced: /ˈkiːbɔːrd/) is a device with a series of keys that an individual presses to input characters to a computer or other devices.
Etymology
The term "keyboard" comes from the Old English word "key", meaning a tool for opening or closing a lock, and "board", meaning a flat piece of material. The term was first used to describe the musical instrument, and later applied to the typing device due to the similar arrangement of keys.
