What is Telecommunications.

Telecommunications are an important pillar of the information society. Whether it is in human social and economic activities, or in all aspects of people's daily life, telecommunications are inseparable from this efficient and reliable means.

What is "telecommunications"? ITU defines it as: "Communications using wire, radio, optical or other electromagnetic systems."

According to this definition, any process in which the sender transmits information to one or more receivers using any electromagnetic system, including wired telecommunications systems, wireless telecommunications systems, optical communication systems, and other electromagnetic systems, in any form of representation, including symbols, words, sounds, images, and various visible, audible, or usable signals formed by these forms, is called telecommunications. It includes not only traditional telecommunications such as telegraph and telecommunications, but also modern telecommunications such as optical fiber communications, data communications, and satellite communications, which not only include the above-mentioned two-way transmission of information, but also include one-way information transmission such as radio and television.

The history of human beings using electricity to transmit information began with the telegraph. The telegraph is a way of transmitting information in symbols, the so-called digital method, but after the invention of the telegraph in 1876, in the field of telecommunications, the analog method has an absolute advantage. In the 50s of the 20th century, the emergence of PCM technology made the digital communication mode see a ray of light.

But its real growth and development, and even its domination of the world, mainly relied on the power of electronic computers. Therefore, some people regard "c c" (that is, the convergence of communication and computers) as an important symbol of a new revolution in the history of human information. Today, when we talk about "telecommunications," we cannot but talk about the wide range of applications of computers in various telecommunications fields.

It not only plays a key role in realizing the intelligence of telecommunications, but also makes telecommunications no longer simply "transmit" information, but also increases the function of information processing and storage.

Telecommunications began with wired communication using metal wires, and by the end of the 19th century, wireless telegraphy appeared, making wireless communication methods a whim. However, due to some inherent weaknesses in wireless communication, it was difficult to overcome under the technical conditions at that time, so for a long time, it was generally in a "standby" position, except for specific conditions such as navigation and disaster relief. Due to the development of technology, not only the wireless mode has made a comeback, but also a new communication mode with optical fiber as the transmission.

This not only brings about the diversification of telecommunication transmission methods, but also lays a material foundation for the high-speed and personalization of telecommunications.

From the above, it can be seen that over the past 100 years, although the basic concept of telecommunications has not changed, its extension has undergone great changes. The dominance of the ** has been shaken, the information superhighway, the Internet is coming, they have brought an unprecedented impact on the concept and way of traditional telecommunications.
