What’s the difference between half-duplex and full-duplex?

Full-duplex means that speech can be simultaneously transmitted & received (As you would on talking a phone call).

Half-duplex requires transmission to communicate (Push-to-talk switch).

What is Half-Duplex?

Half-duplex communication is a communication method where information can be transmitted in both directions, but only in one direction at a time. This means that the communication channel can either transmit or receive information, but not both simultaneously.

In other words, when one device is transmitting data, the other device can only receive data, and vice versa. This is in contrast to full-duplex communication, where both devices can transmit and receive data simultaneously.

Examples of half-duplex communication include two-way radio, walkie-talkies and CB radios, where only one person can talk at a time and the other person must wait until the first person has finished speaking before they can transmit their own message. Another example is the Ethernet bus topology, where nodes can send and receive data, but only one node can send data at a time.
