What is telecommunication?

•The transmission of information that allows for communication between people who are separated by distance.

Examples of Telecommunication :•telephone system•satellite communication system •mobile cellular system •radar and sonar systems •microwave radio systems •TV and radio broadcasting systems •space discovery using telecommunications •oil exploration using radio frequency analysis warfare communications•information and intelligent gathering

Three units of telecommunication:A) A transmitter that takes information and converts it to a signal.B) A transmission medium, also called the “physical channel” that carries the signal.C) A receiver that takes the signal from the channel and converts it back into usable information.

Basic Elements of Telecommunication

Sender•who uses a transmitter which converts the message into a signal.Transmitter• transmits the information through a medium to the receiver which transmits the signals into information that can be used and understood by people.

Transmission medium• carries the signal

Sender• receives the signal and converts it back into usable information

Channel • responsible to transfer the information from the source to the destination without distortion or loss of information. Channels tend to be affected by external signals or noise. To achieve this a variety of "protocols" or rules are used.

Telecommunication network• represent all the players that make telecommunication possible, from the transmitters and receivers to the communication mediums that make it possible for the messages to be transmitted.

Telecommunication medium•refers to the channel that carries the signal between a transmitter and a receiver. Examples of telecommunication media in our modern times are optical fibre as well as cables.
