What is the Meaning & Definition of telecommunication

The concept of telecommunications encompasses all forms of remote communication. The Word includes the Greek prefix tele, which means 'distance' or 'far '. That said, the telecommunication is a technique that consists of the transmission of a message from one point to another, usually with the particularity of being bi-directional. Telephony, radio, television and data transmission with computers are part of the telecommunications sector. It is the English physicist James Clerk Maxwell, who has set up bases for the development of the telecommunication, by introducing the concept of electromagnetic wave to describe using maths the interaction between electricity and magnetism. Thus, Maxwell would have said that it was possible to propagate waves by free space through electric shocks, which was certified later by Heinrich Hertz in 1887.
The history of telecommunications began to expand towards the first half of the 19th century, with the electric telegraph (which allowed to send messages with letters and numbers). Later appeared the grace phone to which it has become possible to communicate by making use of the voice. With radio waves, wireless communication has come to revolutionize the habits of humanity.
It is clear that the technological innovations in the field of telecommunications are never arrested. The modem has made possible the transmission of data between computers and other devices, thus constituting the starting point for the development of Internet and other computer networks.
At present, telecommunications are part of an industry that makes brewing millions of euros each year worldwide.
