    Which data communication method is used for sending data in both directions at the same time?

    A)  Super duplex                

    B)  Simplex

    C)  Half duplex      

    D)         Full duplex  

    Correct Answer: D

    Solution :

     A full-duplex (FDX), or sometimes double-duplex system, allows communication in both directions, and, unlike half-duplex, allow 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. Examples: Telephone, Mobile Telephone, etc.
