Which transmission allows data to travel in both directions but only one direction at a time?
Correct answer: B. Half duplex
- A. Simplex
- B. Half duplex
- C. Full duplex
- D. Reverse duplex
Explanation
Half duplex transmission allows data to travel in both directions, but only in one direction at a time. Walkie-talkies are a common example of half-duplex communication. With walkie-talkies, only one person can transmit at a time, and the other person must wait until the first person is finished speaking before they can reply.
