Answer:
There
are three ways, or modes, for transmitting data from one point to another. The
names are shown down__
1. Simplex.
2. Half
Duplex.
3. Full
Duplex.
Simplex mode:
If transmission mode is simplex, communication can take place in only
direction. Devices connected to such a circuit are either a sender or only a
receiver.
Half Duplex mode:A
Half Duplex system can transmit data in directions, but only in one direction
at a time. Thus a half duplex line can alternately send and receive data. It
requires two wires.
Full Duplex:
A full duplex is use that allows information to flow simultaneously in both
directions on the transmission path.
