Meaning – In the context of computing and networking, the word duplex, refers to the type of communication, in which data can be transmitted and received at the same time.
Duplex transmission is classified into two types – half-duplex transmission and full-duplex transmission.
In half-duplex mode, each station can both transmit and receive, but not at the same time. When one device is sending, the other can only receive, and vice versa.
In full-duplex mode, both stations can transmit and receive simultaneously. In full_duplex mode, signals going in one direction share the capacity of the link with signals going in another direction.
Example of usage – “One of the best examples of duplex communication, is the telephone, as people can listen and talk to the person on the other end of the line, simultaneously.”
