Mode
Only unidirectional communication is practicable on half duplex mode, and bidirectional
communication is practicable on full duplex mode. By transmitting packet for two ways,
Ethernet bandwidth is enlarged two times- 10Mbps to 20Mbps, 100Mbps to 200Mbps.

5.2.5 Flow
Control
Ethernet ports on the switches use flow control to restrain the transmission of packets to
the port for a period time. Typically, if the receive buffer becomes full, the port transmits a
pause packet that tells remote ports to delay sending more packets for a specified period
time. In addition, the Ethernet ports can receive and act upon pause packets from other
devices.
