Modes of Data Transmission: Simplex, Half Duplex, Full Duplex

Modes of Data Transmission:

A data transmission mode defines how the data travels from sender to receiver. There are three ways or modes of transmitting data from one point to another. These are Simplex, Half-duplex and Full-duplex.


In this mode data can be transmitted in one way only, means devices connected to such a circuit is either send only or a receive only device. For Example TV and Radio station sends out electromagnetic signals. The station does not monitor for the return signal from the television set. This type of channel design is easy and inexpensive to set up.simplex

Half Duplex:

In Half duplex mode data transmission can take place in both direction but not at the same time. This is the most common type of transmission for computers over telephone network because only one person is supposed to speak at a time. It is also used to connect terminal with a computer. Fax transfer is another example of half-duplex communication mode. Another example of half duplex communication is Willkie talkie communication.half duplex

Full Duplex:

This is the best mode of transmission because signals can be transmitted in both the directions at the same time. This is the fastest mode of transmission. Telephone signals,full duplex

Mobile, computer transmissions are the examples of full duplex mode of transmission. In this type of mode, both the end devices are sender as well as receiver.
