Data flow--
The communication between two devices is:-
1)Simplex:-In simplex mode, the communication is unidirectional, as on a one-way street. Only one of the two devices on a link can transmit; the other can only receive .
Keyboards and traditional monitors are examples of simplex devices. The keyboard can only introduce input; the monitor can only accept output.
2.)Half-Duplex:-In half-duplex mode, each station can both transmit and receive, but not at the same time.:
When one device is sending, the other can only receive, and vice-versa.
The half-duplex mode is like a one-lane road with traffic allowed in both direct
ions. When cars are traveling in one direction, cars going the other way must wait.
3)Full-Duplex:-In full-duplex mode (duplex), both stations can transmit and receive simultaneously .
The full-duplex mode is like a two-way street with traffic flowing in both direct
ions at the same time. In full-duplex mode, signals going in one direction share the
capacity of the link with signals going in the other direction. This sharing can occur in
two ways: Either the link must contain two physically separate transmission paths, one
for sending and the other for receiving; or the capacity of the channel is divided.
between signals traveling in both directions.
One common example of full-duplex communication is the telephone network.
