The communication is bi-directional, or the data flow in both ways, in full-duplex mode. The message can be sent and received simultaneously by both stations.
In this article, we will look more into Full-Duplex Mode in Computer Networks according to the GATE Syllabus for (Computer Science Engineering) CSE. We will read ahead to find out more about it.

What is Full-Duplex Mode in Computer Networks?
Both stations can transmit as well as receive at the same time in full-duplex mode. Full-duplex mode allows signals travelling in opposite directions to share the link’s capacity. This sharing can take place in one of the following two ways:
- Two physically distinct transmission pathways, one for transmitting and the other for receiving, must be present on the link.
- Alternately, signals that are moving in both directions share the available capacity.
Uses
When constant communication in both directions is needed, the full-duplex mode is employed. But the channel’s capacity needs to be split between the two directions. As an illustration, consider a telephone network where two people can speak and listen to each other at the same time over a phone line.
Channels
There are two simplex channels in full-duplex mode, one with traffic going in one way and the other in the other direction. The quickest method of device communication is the full-duplex mode.
Example
Switches are the most typical example of the full-duplex mode. A switch can both send as well as receive data at the same time.
Advantage
Data can be sent and received simultaneously by both stations.
Disadvantage
The capacity of a communication channel is split into two parts if there is no dedicated path between the devices.
