Explanation:
Half-Duplex :
In a half-duplex transmission mode, the communication between sender and receiver occurs in both the directions but, one at a time. The sender and receiver both can transmit and receive the information but, only one is allowed to transmit at a time.
Half duplex is still a one way road, in which a vehicle traveling in opposite direction of the traffic has to wait till the road is empty. The entire channel capacity is utilized by the transmitter, transmitting at that particular time.
Example - An example of a half-duplex device is a walkie-talkie, a two-way radio that has a push-to-talk button. Examples are broadcast radio and television, garage door openers, baby monitors, wireless microphones, and surveillance cameras. In these devices, the communication is only in one direction.
Simplex:
In a simplex transmission mode, the communication between sender and receiver occur only in one direction. That means only the sender can transmit the data, and receiver can only receive the data. The receiver can not reply in reverse to the sender. Simplex is like a one-way road in which the traffic travels only in one direction, no vehicle from opposite direction is allowed to enter. The entire channel capacity is only utilized by the sender.
Example - Examples of Simplex mode are radio, keyboard, and monitor.
