simplex communication









































simplex communication is a communication channel that sends information in one direction only.









































the international telecommunication union definition is a communications channel that operates in one direction at a time, but that may be reversible; this is termed half duplex in other contexts. a duplex communication channel requires two simplex channels operating in opposite directions.

communication channel









































a communication channel or simply channel refers either to a physical transmission medium such as a wire, or to a logical connection over a multiplexed medium such as a radio channel in telecommunications and computer networking. a channel is used to convey an information signal, for example a digital bit stream, from one or several "senders" (or transmitters) to one or several "receivers". a channel has a certain capacity for transmitting information, often measured by its bandwidth in hz or its data rate in bits per second.
