Right Answer is: C
SOLUTION
Concept:
The data flow between the two devices can be in simplex, half-duplex, and full-duplex modes.
Simplex:
- In Simplex, communication is unidirectional. Only one of the devices sends the data and the other one only receives the data.
- The channel capacity is used by only one device all the time.
Example: A CPU sends data while a monitor only receives data.
Half Duplex:
- In half-duplex, both the stations can transmit as well as receive but not at the same time. When one device is sending others can only receive and vice-versa
- The channel capacity is shared by both the devices but at a time only once the device uses the full capacity.
Example: A walkie-talkie
Full Duplex:
- In Full-duplex mode, both stations can transmit and receive at the same time.
- The channel capacity is shared by both communicating devices at all times.
Example: Mobile phones
