Remote Control

A remote control is an electronic device used for the remote operation of a machine.

The term, sometimes abbreviated to “remote” and also called a “controller”, “flipper”, “clicker”, or “changer” is most commonly used to refer to a remote control for televisions or other consumer electronics such as stereo systems and DVD players, and to turn on and off a mains plug/socket. Remote controls for these devices are usually small wireless handheld objects with an array of buttons for adjusting various settings such as television channel, track number, and volume. In fact, for the majority of modern devices with this kind of control, the remote contains all the function controls while the controlled device itself only has a handful of essential primary controls. Most of these remotes communicate to their respective devices via infrared (IR) signals and a few via radio signals. They are usually powered by small AAA or AA size batteries.
