Their are three basic types of communication SYSTEM, which are-

1) Simplex Communication System:

Here, the communication system that is capable of transmitting INFORMATION through, CALLED simplex transmission system. In simplex type, one unit is equipped with a transmitter and the other side is equipped with only one receiver but communication is done only one way by transmitter.

For Example: T.V. broadcast system.

2) Half-Duplex Communication System: 

Here, the communication system that is capable of transmitting information in both directions but the flow is only one way at a GIVEN time that why it is known as half-duplex. In HDX type, one unit is equipped with transmitter as well receiver at one end and a transmitter-receiver at the other end but information can’t flow simultaneously in both the directions.

For Example: Walkie-Talkie”

3) Full Duplex Communication System:

Here the flow of communication takes place in both the direction simultaneously. Full-duplex Ethernet connections work on the principles of full-duplex where data packets are received and sent simultaneously at a given time.

For Example: Phone
