Transmission Mode

The way in which data is transmitted from one device to another device is known as transmission mode.
It is divided into 3 categories - Simplex Mode, Half-Duplex, Full-Duplex

1. Simplex Mode

Definition: Data Flow in one direction
Example: Keyboard and monitor - Keyboard can only accept data from the users. Monitor can only display data from the users.
Advantage: The station can utilize the entire bandwidth of the communication channel.
Disadvantage: Communication is unidirectional.

2. Half-duplex Mode

Definition: Data transmission in either direction but not simultaneous.
Example: Walkie-talkie.
Advantage: Both the device can send and receive data.
Disadvantage: When one device is sending data, another has to wait.

3. Full-duplex Mode

Definition: Communication is birectional.
Example: Telephone Network
Advantage: Both the device can send and receive data simultaneously.
Disadvantage: Capacity of communication channel is divided into two parts.
