|Appareil de communications|
A communications appliance transmits and receives electronic or digital information as data or sound.
Communication appliances may be fixed in place or may be able to be moved from one space to another. Communication appliances require an electrical supply that may be supplied either by an electrical circuit or provided from a local battery source.
