These intermediates play a role in regulation and control of the message being transmittedand received . The fundamental units of any telecommunication system are: transmitter, transmission medium and receiver. The role of transmitter is to convert the transmissible information into a readable signal. The transmission medium is a physical channel that carries the signal. The receiver converts this signal in to a readable form. A telecommunications network is a collection of these transmitters, receivers and communication channels. The communication channel can be physical and through the atmosphere. Electromagentic signals like radio waves, infrared waves, visible light, ultra violet light are examples of communication through atmosphere. Optical fibers and coaxial cables are examples of physical communication.
