A keyboard is an arrangement of rectangular buttons or keys. The characters are printed or engraved on the keys. Almost all keyboard keys produce letters, numbers or signs. Other actions are available by simultaneously pressing more than one key. One such example is the Control-Alt-Delete combination. This command brings up a window on most versions of Microsoft Windows.


Different layouts for the keyboards are available depending on varied needs of people. These needs may vary depending on the language of people or the purpose for which the keyboard is being used. The best alternative layout for the keyboard is the Dvorak Simplified Keyboard. However, this layout is not in widespread use.
