• Simplex


• Half duplex


• Full duplex

Simplex

In the simplex mode of the data flow,the data will be transferred in only one direction i.e.,From the transmitter to the receiver

Half duplex

In the half duplex the data can be transfered in both the direction i.e from transmitter to receiver and from receiver to transmitter.Here the limitation is that the data will be transfered in only on direction at a time either from transmitter to receiver or from receiver to transmitter

Full duplex

in Full duplex communication the data is transfered in both the direction at the same time
