Detailed explanation-1: -A keyboard contains many mechanical switches or push-buttons called “keys". When one of these are pushed, an electrical circuit is closed, and the keyboard sends a signal to the computer that tells it what letter, number or symbol it would like to be shown on the screen.
Detailed explanation-2: -With a computer keyboard, a key is one of the keyboard’s buttons. Letters, numbers, functions, and symbols are all represented on keys. For example, the picture shows the Windows key, a keyboard key found on most keyboards today.
Detailed explanation-3: -Why are the buttons on keyboards called ‘keys’? Because they were originally based on mechanical typewriters which had levers with letters at the end connected to them. They also look a lot like the “keys” on a piano which just pushes the question back a couple of centuries.
