What is the most traditional mode of communication?

The communication mode of traditional walkie-talkie is half duplex.

Simplex communication refers to the mode that data transmission can only be transmitted in one direction. For example, point A can send information to point B, but point B cannot send information to point A. ..

Full duplex communication is the opposite of simplex communication. Point A can send information to point B, and point B can also send information to point A. Both parties can send messages to each other at the same time. The biggest advantage of this communication method is that it is very efficient, but its disadvantages are also obvious. It requires both the receiver and the sender to have the ability to receive and send information.

Half-duplex works in a similar way to full duplex, but it is definitely different from full duplex because it is "half-duplex". The same point is that point A can send messages to point B, and point B can also send messages to point A ... The difference is that half duplex can't let two points send and receive messages at the same time, but can only transmit messages in one direction at the same time.
