Detailed explanation-1: -In telecommunication, duplex communication means that both ends of the communication can send and receive signals at the same time. Full-duplex communication is the same thing.
Detailed explanation-2: -The channel capacity, C, is defined to be the maximum rate at which information can be transmitted through a channel. The fundamental theorem of information theory says that at any rate below channel capacity, an error control code can be designed whose probability of error is arbitrarily small.
Detailed explanation-3: -In the event of a half-duplex, the capacity of a network is equal to the bandwidth multiplied by the propagation delay. In the event of a full duplex, the capacity is twice the multiplication of the bandwidth and the propagation delay.
Detailed explanation-4: -Full duplex transmission mode is like a two-way road, in which traffic can flow in both directions at the same time. For example, in a telephone conversation, two people communicate, and both are free to speak and listen at the same time.
Detailed explanation-5: -A commonplace example of full duplex communications is a telephone call where both parties can communicate at the same time. Half duplex, by comparison, would be a walkie-talkie conversation where the two parties take turns in speaking.
