Communication Model and Tasks

A Communications Model

The communication process is as follows:

• The source is where the data is generated. Serves as an input to the transmitter.
• The transmitter transforms the data from the source (eg. 1s and 0s) into electromagnetic signals (energy).
• The transmission system (or transmission medium) is where the information, encoded as electromagnetic signals, travels to reach the destination.
• The receiver takes the signal from the transmission system and tries to transform it back into the source data form (eg. 1s and 0s). Serves as the input to the destination.
• The destination takes the incoming data from the receiver.

Communications Tasks

• Transmission system utilization
