Full duplex (FDx) is a bidirectional type of communication system where two end nodes send and receive data signals at the same time, and a single carrier is simultaneously used for dual communication.
Full duplex is also known as double duplex.
To send or receive data, the participating nodes in a FDx system do not have to wait for a free carrier/medium. This type of system typically employs a medium that has at least two internal channels – one for sending and one for receiving.
One of the most common examples of FDx is a phone system, which enables bidirectional communications. Another common example is a computer modem, which may be used to receive and send data at the same time.
