Full-duplex

Full-duplex communication transmission is a term

At the same time transitions is only allowed either party may transmit information, and other one party cannot transmit to party

Full-duplex is in microprocessor and peripheral equipment by sending line between independent and accept line method, can make the data in both directions simultaneously transmit operation. To send data refers in the also able to receive data, both synchronously, it seems we usually call is same, also can hear speaking the voice on the other. The current nic generally support full-duplex.

Half-duplex, so-called half-duplex refers to a period only an action happens, give a simple example, a narrow road, also can have a car through, when there are two car folio volume at present, this kind of circumstance can only a car first, wait until after the other one head again, this example is the description of the image of half-duplex principle. Early interphone, as well as early hubs etc equipment are based on half-duplex products. As technology advances, half double union gradually withdraw from the stage of history.

Full-duplex Ethernet use two cables, rather like the half-duplex mode that USES a pair of cable. Full-duplex mode in sending equipment of the sender and the receiver between the receiving device adopt point-to-point connections, this means that in full-duplex transmission mode, can get higher data transfer rate.
