Difference between Half Duplex and Full Duplex

Half duplex can not send and receive at the same time. It also has algorithms to detect and handle collisions (CSMA-CD). Think of it like a walkie talkie or a CB radio, only on a network. Full duplex can send and receive at the same time. Think of it as a telephone. One issue that can arise is sometimes you will see a 100 Mbps half duplex connection which should almost never happen. Since the 100 Mbps connection will most likely not be detecting collisions (it expects to be full duplex)
