Modes of Data Communication
By the end of the lesson you should be able to: State and define the three modes of data Communication
Simplex Mode: it is used when data is transmitted in one direction only. For example, in radio broadcasting, the listener cannot communicate back through the radio receiver.
Half Duplex: Used when two interconnected devices wish to exchange data alternately, that is, the two devices switch between send and receive modes after each transmission. An example is a radio call
Full Duplex/Duplex transmission: Here data is exchanged between the devices in both directions simultaneously.An example in communication through cell phone
