Half Duplex Transmission vs. Full Duplex Transmission: What's the Difference?

Edited by Sawaira Riaz || By Sumera Saeed || Updated on October 26, 2023
Half duplex transmission allows communication in both directions, but not simultaneously, while full duplex transmission allows simultaneous two-way communication.

Key Differences

Half duplex transmission supports two-way communication, but data can flow in only one direction at a time. Full duplex transmission allows simultaneous two-way data flow.

In half duplex transmission, a device must wait for the other to finish transmitting before responding. In full duplex transmission, both devices can send and receive at the same time.
