Like the
half duplex system, the full duplex system requires two frequencies, one to transmit and one to receive.
Full duplex flow control per IEEE802.3X and
half duplex back pressure, symmetric and asymmetric
This processor's dual Fast Ethernet controllers function at full or
half duplex at 10/100 Mbps.
Supporting full and
half duplex mode with flow control, the device allows reliable and simultaneous data transmission.

half duplex back pressure, symmetric and asymmetric
The switches are available for 10/100Base-T, 4/16 token ring, and 10/100Base-T switched
half duplex. --Digitech-LeCroy
As a result, they blocked the exchange of auto-sensing information, making it necessary to manually configure the hub, switch, or router port to either full or
half duplex. In the best case, this required time-consuming intervention at the management console (or removing the cover to configure dip switches).
Most medium- and low-speed (T1 and below) bridges are already full duplex; however, virtually all high-speed bridges are
half duplex.
