 | Mouse
A
computer mouse is a pointing device (hand control) that detects
two-dimensional motion relative to a surface. This motion is typically
translated into the motion of a pointer on a display, which allows for
fine control of a graphical user interface. |
 | Keyboard
A
computer keyboard is a typewriter-style device which uses an
arrangement of buttons or keys to act as mechanical levers or
electronic switches. |
 | Speaker
Computer
speakers, or multimedia speakers, are speakers sold for use with
computers, although usually capable of other audio uses, e.g. for an
MP3 player. |
 | Controller
A
game controller is a device used with games or entertainment systems to
provide input to a video game, typically to control an object or
character in the game. A controller is usually connected to a game
console or computer by means of a wire or cord, although, since the
mid-2000s, wireless controllers have become widespread. |
