Data Transmission Modes

Data communication is concerned specifically with the issues that must be considered when communicating data between two devices, generally computers. There are basically 3 modes of data communication.


1. Simplex - In simplex data transmission, data is directed one way. There is no any space for data transmission to be directed the other way. The best examples which can be mentioned here are television and radio transmission.

2. Half-Duplex - In Half-Duplex data transmission, data can be directed one way at a time. Though data can be transmitted both ways here, till the data transmission to one direction is ended, data cannot be transmitted to the other direction. The best example which can be shown here is Walkie-talkie.

3. Full Duplex - In duplex data transmission, data can be transmitted both ways at a time. The best example which can be shown here is the telephone.
