duplex- two way transmission.Both transmission and reception takes place.

2 types of duplex:

Half duplex:-both transmission and reception takes place,bt nt at d same time.single channel is used .
Full duplex:-both txn and recep...takes place simultaneously using 2 different channels.one for txn and other 4 reception.
