Data Transmission modes in a networkGiven : (i) Simplex            (ii) Half - Duplex            (iii) Full Duplex Network

Data transmission modes refer to the ways in which data is transmitted between devices in a network. Here’s a breakdown of the three main modes:

1. Simplex:

   • In simplex mode, data transmission occurs in one direction only. For instance, a keyboard sends data to a computer but does not receive anything back. Examples include TV broadcasting and traditional keyboard-to-computer connections.

2. Half-Duplex:

   • Half-duplex allows for two-way communication, but not simultaneously. Devices can send and receive data, but one must wait for the other to finish before the next transmission can occur. A common example is a walkie-talkie, where one user must finish speaking before the other can respond.

3. Full Duplex:

   • In full-duplex mode, data transmission can occur simultaneously in both directions. This means that both devices can send and receive information at the same time, similar to a telephone conversation. An example of full-duplex communication is a standard phone call where both parties can talk and listen simultaneously.

Summary

• Simplex: One-way communication (e.g., keyboard to computer).
• Half-Duplex: Two-way communication, one direction at a time (e.g., walkie-talkies).
• Full Duplex: Two-way communication, both directions simultaneously (e.g., phone calls).
