What is the function of telecommunication systems?

Three parts make up a very simple telecommunications system:

Transmitter. It converts information into an appropriate signal for transmission.

Transmission medium. It is the medium that transmits the signal from the transmitter to the receiver.

Receiver. The receiver converts the received signal into information that can be used.

This is the basic structure that makes up, for instance, the internet. The signals are created by converting the messages from every computer using a “protocol stack” ( transmitter). The messages are then broken into packets, which is a smaller data chunk. The packets receive a port and IP address. They are then converted into electronic signals and sent along the telephone line. The IP address is used by a router to determine where the data should be sent. The packets are then reassembled by the protocol stack of the destination computer (receiver), into the message originally sent by the computer.
