The keyboard is the primary user input device. It enables you to communicate with your computer. While the mouse is also a fundamental device to control the PC, the keyboard goes one step further by allowing you to enter specific information as opposed to simply pointing and clicking.
The keyboard connects to the computer through a wire, although wireless keyboards are also available. Variations of the classic keyboard include the addition of action specific buttons, most commonly for Internet features, and split keyboards which angle the two halves of the keyboard to reduce stress on your wrists as you type.
