In _________ data transmission mode, messages can be sent in both directions, but only in one direction at a time.
Show Hint
- Simplex
- Half-duplex
- Full-duplex
- Extended duplex
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.
