TRANSMISSION
Transmission mode means transferring data between two devices.
It is also known as a communication mode.
Buses and networks are designed to allow communication to occur between individual devices that are interconnected.
Simplex Mode –
In Simplex mode, the communication is unidirectional, as on a one-way street.
Only one of the two devices on a link can transmit, the other can only receive.
The simplex mode can use the entire capacity of the channel to send data in one direction.
Example: Keyboard and traditional monitors. The keyboard can only introduce input, the monitor can only give the output.
Advantages:
- Simplex mode is the easiest and most reliable mode of communication.
- It is the most cost-effective mode, as it only requires one communication channel.
- There is no need for coordination between the transmitting and receiving devices, which simplifies the communication process.
- Simplex mode is particularly useful in situations where feedback or response is not required, such as broadcasting or surveillance.
Disadvantages:
- Only one-way communication is possible.
- There is no way to verify if the transmitted data has been received correctly.
- Simplex mode is not suitable for applications that require bidirectional communication.
