Detailed explanation-1: -Simplex is the data transmission mode in which the data can flow only in one direction, i.e., the communication is unidirectional. In this mode, a sender can only send data but can not receive it. Similarly, a receiver can only receive data but can not send it.
Detailed explanation-2: -Simplex transmission can be thought of as a one-way road in which the traffic travels only in one direction-no vehicle coming from the opposite direction is allowed to drive through.
Detailed explanation-3: -In simplex mode, the communication is unidirectional. In half-duplex mode, the communication is bidirectional, but one at a time. In full-duplex mode, the communication is bidirectional. A device can only send the data but cannot receive it or it can only receive the data but cannot send it.
