Related Post: Difference between Analog and Digital Circuit – Digital vs AnalogĬommunication is mainly classified into two main types Analog and Digital communication.It is the most common mode of communication being used in the Telecommunication engineering world. It uses two individual channels for sending and receiving the signal. For example walkie-talkieįull Duplex Communication: It is a two-way communication where the information or signal can travel in both directions at the same time. It can either send the signal or receive the signal at a time. Half Duplex communication: It is a two-way communication using a single channel but the information can travel in only one direction at a time. The receiver cannot transmit back the signal. The sender sends the signal and the receiver receives it using a single channel. Simplex communication: it is a one-way communication that allows the transfer of information in only one direction. The communication can be classified into simplex, half-duplex and full-duplex modes of transmission.

The medium used for the transfer of signal could be a wire (for wired communication) or radio signals (for wireless communication).

The information being sent could be an audio, video, or any other encoded data. In Electrical and Electronics engineering, communication means the exchange of any kind of information in the form of the electrical signal between two devices through a transmission medium.

Main Differences between Serial and Parallel CommunicationĬommunication is the process of exchange of any useful information between two participants.
