Communication between source and destination:
The key elements of a communication model are as follows:
Source: The device which generates the data to be transmitted. Examples telephone, computers.
Transmitter: A transmitter transforms and encodes the information in such a way as to produce ectromagnetic signals that can be transmitted across some sort of transmission system, For example, a modem takes a digital bit stream from an attached device such as a personal computers and transforms that bits stream into an analog signal that can be handled by the telephone network.
Transmission System: This can be a single transmission line or a complex network connecting source and destination.
Receiver: The receiver accepts the signal from the transmission system and converts it into a form that can be handled by the destination device.
For example, a modem will accept an analog signal coming from a network or transmission line and convert it into a digital bit stream.
Destination: Takes the incoming data from the receiver.
