[#395] The method of communication in which transmission takes place in both directions, but only one direction at a time is called
Correct Answer
(D) Half Duplex
Explanation
Solution: A. Simplex: Simplex communication is a method of communication where transmission occurs in only one direction. It does not support two-way communication. B. Four wire circuit: A four-wire circuit refers to a communication channel that uses separate wires for transmission and reception, allowing for simultaneous two-way communication. However, this option does not describe the scenario where only one direction is allowed at a time. C. Full Duplex: Full duplex communication is a method where transmission can occur simultaneously in both directions. It allows for two-way communication simultaneously, which is not the case in the given scenario. D. Half Duplex: Half duplex communication is the correct answer. In this method, transmission can take place in both directions, but only one direction can occur at a time. The communication switches between the two directions, allowing communication in both directions but not simultaneously. Therefore, the correct answer is: D. Half Duplex
