Full-Duplex Communication
Unlike half-duplex, full-duplex Ethernet supports simultaneously
communication by providing separate transmit and receive paths. This
effectively doubles the throughput of a network interface.
Full-duplex Ethernet was formalized in IEEE 802.3x, and does not use
CSMA/CD or slot times. Collisions should never occur on a functional fullduplex
link. Greater distances are supported when using full-duplex over
half-duplex.
Full-duplex is only supported on a point-to-point connection between two
devices. Thus, a bus topology using coax cable does not support full-duplex.
Only a connection between two hosts or between a host and a switch
supports full-duplex. A host connected to a hub is limited to half-duplex.
Both hubs and half-duplex communication are mostly deprecated in modern
networks.
