Question
In _______ transmission, both devices may transmit simultaneously.
Select one:
- duplex
- half-duplex
- simplex
- half-simplex
Solution
The correct answer is duplex transmission.
Explanation
-
Duplex Transmission: This allows both devices to communicate with each other simultaneously. There are two types of duplex communication:
- Full Duplex: Both devices can transmit and receive data at the same time (e.g., a telephone conversation).
- Half Duplex: Devices can both send and receive information, but not at the same time (e.g., walkie-talkies).
-
Half-Duplex: As mentioned, this allows for communication in both directions, but not simultaneously.
-
Simplex: In this mode, data transmission occurs in only one direction (e.g., a keyboard to a computer).
Based on the question’s requirement for simultaneous transmission, duplex is the appropriate choice.
