full-duplex
This is the
communication mode in which a device simultaneously sends and receives over the same link,
doubling the bandwidth. Thus, a full-duplex 100 Mbps connection has a bandwidth of 200 Mbps,
and so forth. A device either automatically adjusts its duplex mode to match that of a
connecting device or you can configure the duplex mode; all devices at 1 Gbps or higher run
only in full-duplex mode.
