The manner in which the communications take place between sender and receiver is called transmission mode. In the language of communications transmission mode is said to be Simplex, Half duplex, Full duplex and Full/full duplex. There are four ways for transmitting data from one point to another.
- Simplex
- Half-Duplex
- Full-duplex
- Full/full-duplex
Simplex
Simplex is the one-way process of data transmission and one-way communication. In simplex mode communication can take place only in one direction. The receiver receives the signal from transmission device. In this mode the flow of information is uni-directional. Examples: TV, Radio, Newspaper etc.
Half-Duplex
In half-duplex we use two ways process of data and two way communication but the restriction is that we use only one way at a time. Examples: Wire less, fax machine etc
Full Duplex
In this technique of networking modes we have two ways data transmission and communication. There is no any restriction we can use both directions at the same time. In full duplex transmission two stations can send and receive data from each other. Examples: Telephone, cell phone etc.
Full/Full-Duplex
In full/full-duplex we use two way communications. In full/full-duplex transmission mode two stations will communicate with each other but with the help of third station. Example: Internet.
