Full- and Half-Duplex Communications


Hi Everybody,

Today we are idea gather  Full- and Half-Duplex Communications means………….


Full-duplex mode communications permit simultaneous two-way communications. A device can both send and receive at the same time, which means that neither device can use the full bandwidth. Half-duplex mode communications permit two-way communications, but in only one direction at a time. When one device sends, the other must receive; then they can switch roles to transfer information in the other direction. Each device can use the full bandwidth when it is sending.


Example:  Full- and Half-Duplex Devices

Telephone communications are full-duplex. Both parties can talk and hear at the same time. Walkie-talkies or CB radios are half-duplex; one party talks while the other listens.
