  • Simplex
  • Half-duplex
  • Full-duplex
  • Extended duplex
Show Solution

The Correct Option is B

Solution and Explanation

In half-duplex mode, devices can communicate in both directions, but only one at a time. When one device transmits, the other must wait until transmission concludes before sending data.
Alternative transmission modes:

  • Simplex: Unidirectional data flow.
  • Full-duplex: Simultaneous bidirectional data flow.

Half-duplex is typical for walkie-talkies and certain network setups requiring two-way communication without simultaneous transmission.
