Communication is an act of conveying a signal or a message. It must involve a sender and a receiver and their reactions. Face to face communication is done daily but there is a limitation. This is only applicable when the distance over the communication is short.
Telecommunication is a kind of communication that uses devices. This was discovered when there was a need to improve communication in long distances. How is it possible for people to communicate with each other, one from the east end of the earth and one from the west end of the east, only by shouting or even reaching the maximum volume of voice?
To solve this need of people, pioneer of telecommunications came up with an idea. It is the use of electric devices to connect the signals or message to the sender and receiver even in long distance. Alexander Graham Bell is known for inventing the first telephone. After years, telecommunication developed from telephone to mobile phone, to radio, to television, to internet and so on. Now, it is usually called telecommunications ( in plurality) since so many electric devices are used. In telecommunication, signals, audio, visuals, sounds are emitted through wires and other electromagnetic systems.
Conclusively, telecommunication is the exchange of ideas between sender and receiver with the involvement of technology.
In the history, long distance communication began from smoke signals but it is a bit inconvenient when the weather is foggy. Over time, communication satellites and networks had been established. Other electromagnetic devices used in telecommunication include cables, telegraphs, etc.
