3.7.5 Simplex, Half-Duplex, and Full-Duplex Operation
The data channels over which a signal is sent can operate in one of three ways: simplex,
half duplex, or full duplex. The distinction among these is in the way the signal can travel. Simplex
transmission, as its name implies, is simple. It is also called unidirectional because the signal
travels in only one direction, just like traffic flows on a one-way street.
Television or radio transmission is an example of simplex communication, as illustrated
in Figure 3-17.
