The way in which data is transmitted from one place to another is called data transmission mode. There are three types of data transmission modes:
• Simplex mode
• Half duplex mode
• Full duplex mode
1. Simplex Mode
In simplex mode, data can flow only in one direction. It cannot be moved in both directions. It operates in a manner similar to a one-way street. The direction of flow never changes. A device with simplex mode can either send or receive data. It cannot perform both actions.
An example is a traditional television broadcast. The signal is sent from the transmitter to TV antenna. There is no return signal.
2. Half-Duplex Traffic
In half-duplex mode, data can flow in both directions but not at the same time. It is transmitted one-way at one time. A device with half-duplex mode can send or receive data but not at the same tune. That is why the speed of half-duplex mode is slow.
Internet surfing is an example of half-duplex communication. The user issues a request for a web page. The web page is downloaded and displayed before user issues other request,
3. Full-Duplex Mode
In full-duplex mode, data can travel in both directions simultaneously. Full duplex mode is a faster way of data transmission as compared to half duplex. Time is not wasted in changing the direction of data flow.
A telephone is a full duplex device. Both persons can talk at the same time. Another example of full-duplex communication is automobile traffic on a two-lane road. The traffic can move in both directions at the same time.

Why mobile phone is the example of full duplex transmission mode? If both data will go through the same path then the data can be colloide.
