Duplex, or two-way communication, refers to an electronic communication system that exchanges information between two points.
In duplex communication, using two communication lines, one for each transmission direction, is simple, but various transmission methods are used to save on transmission paths.
Communication modes in electronic communication
Full duplex (Full Duplex)
A communication mode in which two terminals simultaneously use separate, independent lines to send and receive data. Typical examples are telephone networks and high-speed data communication.
