Difference between Simplex, Half duplex and Full Duplex Transmission Modes

Prerequisite – Transmission Modes in Computer Networks

There are 3 types of transmission modes which are given below: Simplex mode, Half duplex mode, and Full-duplex mode. These are explained below.

1. Simplex mode: In simplex mode, Sender can send the data but the sender can’t receive the data. It is a unidirectional communication.
   
2. Half-duplex mode: In half-duplex mode, Sender can send the data and also can receive the data one at a time. It is two-way directional communication but one at a time.
3. Full duplex mode: In full-duplex mode, Sender can send the data and also can receive the data simultaneously. It is two-way directional communication simultaneously.

Difference between Simplex, Half duplex, and Full Duplex Transmission Modes:

S. No.	Parameters	Simplex	Half Duplex	Full Duplex
1.	The direction of communication	Simplex mode is a uni-directional communication.	Half Duplex mode is a two-way directional communication but one at a time.	Full Duplex mode is a two-way directional communication simultaneously.
2.	Sender and Receiver	In simplex mode, Sender can send the data but that sender can’t receive the data.	In Half Duplex mode, Sender can send the data and also can receive the data but one at a time.	In Full Duplex mode, Sender can send the data and also can receive the data simultaneously.
3.	Channel usage	Usage of one channel for the transmission of data.	Usage of one channel for the transmission of data.	Usage of two channels for the transmission of data.
4.	Performance	The simplex mode provides less performance than half duplex and full duplex.	The Half Duplex mode provides less performance than full duplex.	Full Duplex provides better performance than simplex and half duplex mode.
5.	Bandwidth Utilization	Simplex utilizes the maximum of a single bandwidth.	The Half-Duplex involves lesser utilization of single bandwidth at the time of transmission.	The Full-Duplex doubles the utilization of transmission bandwidth.
6.	Suitable for	It is suitable for those transmissions when there is requirement of full bandwidth for delivering data.	It is suitable for those transmissions when there is requirement of sending data in both directions, but not at the same time.	It is suitable for those transmissions when there is requirement of sending and receiving data simultaneously in both directions.
7.	Examples	Example of simplex mode are: Keyboard and monitor.	Example of half duplex mode is: Walkie-Talkies.	Example of full duplex mode is: Telephone.
