Half-Duplex - Telecommunications

Half-duplex data transmission means that data can be transmitted in both directions on a signal carrier, but not at the same time. For example, on a local area network using a technology that has half-duplex transmission, one workstation can send data on the line and then immediately receive data on the line from the same direction in which data was just transmitted. Like full-duplex transmission, half-duplex transmission implies a bidirectional line (one that can carry data in both directions).
