“Multimedia” indicate that the informationdata being transferred over the network may be composed of one or more of the following media types: Text Images Audio Video The are three ways or media of data communication: Simplex, Half duplex (HDX), Full duplex (FDX): Simplex: In Communication Networks, Communication can take in one connected to such a circuit. The is no mechanism for information to be transmitted back to the sender. Communication is unidirection
