Explanation:
It is the duplex mode. In this mode, communication is in both directions at the same time. And it is different from the simplex or the semi duplex types in which the communication is one way only or one way at a time only. Thus, duplex mode seems to be requiring more bandwidth certainly but it can be advantageous definitely, and in situations like real tine communication, when we don't have the time and want to send as well receive the message at the same time.
