Communication System

Communication over a mobile phone is an example of Full-Duplex communication. In a Full-Duplex system, both parties can communicate with each other simultaneously. This means that while one person is speaking, the other can listen and respond at the same time, without any delay in switching between listening and speaking modes.

In contrast, a Simplex mode allows communication in only one direction, like a traditional radio broadcast where messages are transmitted but not received. Half-Duplex allows two-way communication but not simultaneously; each party must take turns to send messages, typical in walkie-talkies. Double-Duplex is not a standard term used in the context of communication modes.
