Question, comment or suggestion?Full-Duplex
It is the type of communication where data can travel in both directions at the same time. It's similar to a phone call where you can talk and listen at the same time without waiting for the other person to finish.
A full-duplex (FDX) system allows communication in both directions, and, unlike half-duplex, allows this to happen simultaneously. Land-line telephone networks are full-duplex since they allow both callers to speak and be heard at the same time. Full-duplex operation is achieved on a two-wire circuit through the use of a hybrid coil in a telephone hybrid. Modern cell phones are also full-duplex.
