Data Flow


Data Flow
Communication between two devices can be-
1.      Simplex- In simplex mode, the communication is unidirectional (in one direction). Only one of the two communicating devices on a link can send the data: the other can only receive. See the figure.





2.      Half-Duplex – In half-duplex mode, each station(device) can send and receive the data, but not at the same time i.e., when one device is sending, the other can only receive, and vice versa




.


3.      Full-Duplex- In full-duplex mode, both communicating devices can send and receive the data simultaneously (at the same time). It is also called duplex mode. See the figure-
