Detailed explanation-1: -In other words, each station can both transmit and receive the data but not at the same time. When one device is sending the other can only receive and vice-versa.
Detailed explanation-2: -Full-duplex data transmission means that data can be transmitted in both directions on a signal carrier at the same time. For example, on a local area network with a technology that has full-duplex transmission, one workstation can be sending data on the line while another workstation is receiving data.
Detailed explanation-3: -Half-duplex devices can only transmit in one direction at one time. So although data can move in two directions, it cannot be at the same time. Both devices are capable of transmitting and receiving so when one device is sending, the other is receiving.
Detailed explanation-4: -As already mentioned above, the Simplex Mode supports a UniDirectional flow of data. The Half-Duplex Mode supports a BiDirectional flow of data but in one direction at a time. The Full-Duplex Mode supports a BiDirectional flow of data in both directions at the same time (simultaneous flow).
