Data Transmission Modes:
"The path in which data is transmitted from one place to another is called data transmission modes".
![]()
There are three types of data transmission modes:
Simplex Mode
In simplex mode, data is transferred 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 only can send or receive data . It cannot perform both.
Example:
An example is a traditional television broadcast. The signals are sent from the transmitter to TV antenna. There is no return signal.
Half-Duplex Traffic
In half-duplex mode, data can flow in both directions but not at the time. It is transmitted one-way at at one time. A device with half-duplex mode can perform both functions of sending and receiving data but not at the same time. That is way speed of half-duplex mode is slow.
Example:
Internet surfing is an example of half-duplex communication. The user issue a request for a web page. The web page is downloaded and displayed before issuing another request.
Full-Duplex mode
In half-duplex mode, data can flow in both directions but not at the time.Full duplex mode is a faster way of sharing data as compared to other modes of data transmission. time is not wasted in changing the directions of flow.
Example:
A mobile/telephone is a full-duplex device. Both persons can talk at the same time. Another example of full-duplex communication is automobile traffic on the two-lane road. The vehicles can move in both directions at the same time.
