An example of a duplex is a house with two living units with a common wall. 1  double; twofold.  designating or of a system of telegraphy in which two messages may be sent simultaneously in opposite directions over a single circuit.
To compensate, analog signals are amplified, ad digital signals are regenerated through repeaters. In a Half-duplex transmission, signals can travel in both directions over a medium BUT in only one direction at a time. When signals can travel in both directions over a medium simultaneously, the transmission is considered full duplex. A form of transmission that allows multiple signals to travel simultaneously over one medium is known as multiplexing. In multiplexing, the single medium is logically separated into multiple channels, or sub channels. Throughput is the amount of data that the medium can transmit during a given period of time.
