here are three possible ways of data exchange. These are:
1. Simplex: in this, data is transmitted in one direction only. this means one end will always be a transmitter and the other end will always be a reciever.
2. Half-Duplex: in this, data is permitted to flow in either direction, but not silmultaneously. At a given time, the transmission can take place only in one direction.
3. Full-duplex: A transmission system in which data can be transmitted in both directions simultaneously.
