1. Half-duplex mode :
Half duplex mode is when sender can send the data and also can receive the data but one at a time. It is two-way directional i.e bi-directional communication but one at a time.
2. Full duplex mode :
Full duplex mode is when sender can send the data and also can receive the data simultaneously. It is two-way directional i.e bi-directional communication simultaneously.
Difference between Half duplex Transmission Modes and Full Duplex Transmission Modes :
|Sr.No||Half-duplex mode||Full duplex mode|
|1.||The sender can send as well as receive the data but does one task at a time.||The sender can send as well as receive the data at the same time.|
|2.||In Half duplex data flow is two-directional but one at a time.||In Full Duplex data flow is two directional and is simultaneous.|
|3.||Half duplex mode provides less performance than full duplex mode.||Full duplex provides better performance than half duplex mode.|
|4.||In this there is less utilization of bandwidth during transmission.||In this bandwidth utilization is doubled.|
|5.||In this, two systems are connected by a point to point link to transmit and receive signal. Both ends can transmit signal but one at a time.||In this, signals are transmitted in both directions; both end stations can receive and send data at the same time. Full duplex mode requires two independent channels for transmission, one for receiving the data and the other for transmitting the data.|
|6.||Walkie-Talkies and Text message are example of half duplex mode.||Telephone, Instant Chat rooms, Audio Video Calls are example of full duplex mode.|
