Computer keyboard

A computer keyboard is an input device that allows a person to enter characters such as numbers, letters, and other symbols into a computer.

There are different ways the keys on a keyboard are laid out, usually to deal with different regions and languages. The most popular layout is called QWERTY, which is based on the first six letters on typewriter keyboards. However, other layouts have been developed – one such layout is Dvorak, which puts the most common letters in the places that are easiest to reach.
