Question 16

What is the difference between operating in half-duplex mode or full-duplex mode and why does it eliminate collisions?

Accepted Answer

Half-duplex communication means a station can transmit and receive data but not at the same time,much like a two-way radio.Full-duplex mode,by definition,means a NIC can transmit and receive simultaneously.Therefore,when an Ethernet NIC is operating in full-duplex mode connected to a switch,CSMA/CD isn't used because a collision can't occur in full-duplex mode.Because fullduplex mode eliminates the delays caused by CSMA/CD and allows double the network bandwidth,most Ethernet LANs now operate in this mode using switches.
