Prerequisite – Transmission Modes in Computer Networks
1. Simplex Mode :
Simplex mode is as on a one-way street, the communication is unidirectional, as on a one-way street. In this, only one of the two devices on a link can transmit, and the other can only receive. This mode uses the entire capacity of the channel to send data in one direction.
Example:- keyboard and monitor.
2. Half-duplex mode:
Half-duplex mode is when the sender can send the data and also can receive the data one at a time. It is two-way directional i.e. bi-directional communication but one at a time.
Example:- Walkie-Talkies.
Difference between Simplex Transmission Modes and Half Duplex Transmission Modes :

Parameters |
Simplex Mode |
Half-duplex mode |
1. |
Definition |
The sender can send the data but that sender can’t receive the data. |
The sender can send as well as receive the data but does one task at a time. |
2. |
Data Flow |
In simplex mode data flow is Unidirectional. |
In Half duplex data flow is two-directional but one at a time. |
3. |
Bandwidth Utilization |
In this bandwidth utilization is maximum. |
In this there is less utilization of bandwidth during transmission. |
4. |
Performance |
Simplex mode provides worst performance than full-duplex mode. |
Half-duplex mode provides less performance than full-duplex mode. |
5. |
Data Transmission |
In this, one station is the transmitter and the other is the receiver. Here, information is one way, that is, it is only the transmitter that sends data or information. |
In this, two systems are connected by a point-to-point link to transmit and receive signals. Both ends can transmit signals but one at a time. |
6. |
Communication Channel |
Utilization of communication channel capacity in delivering data in one side. |
Bandwidth gets saved by exchanging it alternately between both sides on a single communication channel. |
7. |
Suitable for |
This transmission is suitable when data sending is required in one way only. |
This transmission is suitable when data is sent in both directions, but in opposite directions. |
8. |
Examples |
Keyboard and traditional monitors are an example of simplex mode. |
Walkie-Talkies and Text messages are examples of half-duplex mode. |
