In which communication mode can data be transmitted in both directions simultaneously?

  • Full-Duplex
  • Simplex
  • Half-Duplex
  • None of the Above
Correct Answer: A. Full-Duplex

Detailed Explanation

Full-duplex is a communication mode in which data can be transmitted in both directions simultaneously. This means that two connected devices can send and receive data at the same time. Therefore, Option A (Full-Duplex) is the correct answer.


A full-duplex communication channel provides two-way communication without requiring either device to wait for the other to finish transmitting. Telephone conversations are a common everyday example because both people can speak and listen at the same time.


There are three main communication modes:


Simplex allows data to travel in only one direction. The receiving device cannot send data back through the same communication channel. Traditional television broadcasting is an example of simplex communication.


Half-duplex allows communication in both directions, but not simultaneously. Devices take turns transmitting and receiving. A walkie-talkie is a common example.


Full-duplex allows communication in both directions at the same time, making it suitable for interactive communication where simultaneous transmission and reception are required.


Key Points:



  • Full-Duplex → Both directions simultaneously 

  • Half-Duplex → Both directions, but one at a time

  • Simplex → One direction only

  • Telephone communication is a common example of full-duplex communication.
