Computer keyboard is an input device, partially modeled after the typewriter keyboard, which uses an arrangement of buttons or keys, to act as mechanical levers or electronic switches in computing. It has characters engraved or printed on the keys and each press of a key typically corresponds to a single written symbol on the monitor. To produce some symbols requires pressing and holding several keys simultaneously or in sequence on the keyboard. Most keyboard keys produce letters, numbers or signs (characters), other keys or simultaneous key presses can produce computer commands or actions.

The keyboard is used to type text and numbers into a word processor, text editor or other program in the normal usage. The interpretation of key presses is generally left to the software in the modern computer. Computer keyboard distinguishes each physical key from every other and reports all key presses to the controlling software of the computer. These keyboards are also used for computer gaming, either with regular keyboards or by using keyboards with special gaming features, which can expedite frequently used combinations by keystroke. Computer keyboard is also used to give commands to the operating system of a computer, such as Windows' Control combination, which brings up a task window or shuts down the computer.

There are types of computer keyboards like:
Chorded Keyboard is a computer input device that allows the user to enter characters or commands formed by pressing several keys together.

Others are Virtual Keyboard, Touch screen keyboard, Foldable Keyboard and Laser or Infrared Keyboard.
