Question 6 - General Network Communication Model Flashcards
Describe the elements of a general network communication model.
Communication takes place between a message source and a destination. The object of the process is that the destination receives a message in a format that it can understand. Message sources and destinations can be people or electronic devices. A communication channel connects the sender and receiver and provides a pathway over which the message can travel. This channel is also called the transmission medium. A device is required at each end of the channel to convert the message from the source to a suitable format for transmission, with the reverse process carried out at the destination. At the source this device is called an encoder and sends a signal to a transmitter. At the destination a receiver sends a signal to a decoder, which outputs the message sent.
