Keyboard

The most common input device is the keyboard. The keyboard allows a user to communicate with the PC through keystrokes that represent character data and commands. Virtually every PC sold has a keyboard included as a part of its standard package. In fact, most people take their keyboard for granted and rarely even think about it. As long as the keys work and the user is able to enter data, the keyboard is just fine.

The keyboard, despite its many variations and ergonomic (human engineering) styles is very much a standardized device. Virtually all keyboards, have a standard keyboard layout, connect to a PC with primarily one connector, and are for the most part interchangeable between manufacturers.
