What is Telecommunication?

With the development of technology, telecommunication has started to gain more importance in our security. Telecommunication basically provides any type of text, signal, video or audio transmission. Therefore, it is an important technology to implement information exchange. Communication participants provide this flow of information through cables provided by telecommunications or electromagnetic radiation methods.

The telephone, internet and fiber optic technology that we frequently use in our security are the most concrete examples of telecommunication.

Radio

Marconi (Marconi), who started some important developments in radio waves in 1901, & uuml; nl & uuml; He is one of the Italian inventors. After proving that radio waves could be transmitted to the Atlantic Ocean, it paved the way for wireless communication. To some extent, wireless telegraphy is considered to be the beginning of the radio.

Although in the early 1900s various voices and melodies emerged, this did not bring the desired success. However, during the First World War, the use of radios greatly improved. After the war, commercial publishing achieved great success. Whether it's news or entertainment, broadcast adds a great color to life. In the United States, stereo FM broadcasting gained momentum in the early 1930s.

Telegram and Phone

In 1837, the first commercial telegram sample was created. The device is not considered a new invention. However, it is regarded as an exciting development in electromagnetics. The transatlantic telegraph cable was created in 1866. The telephone was invented in 1876 by A. Bell in a customized working environment. Of course, A. Meucci created the first device that transmits sound and electricity to the device. In 1878, the first commercial telephone service organization was established in London.

Television

Telecom attracts people's attention, mainly because it is based on French. & quot; Tele & quot; Distance in Greek, from Latin & quot; Coommunicare & quot; means sharing. The term telecommunication was first used in 1904 by E. Estaunie. In 1923, after people flashed to the ionosphere, radio waves were transformed back into the radiation. they noticed. More precisely, the claims of some scientists on this subject have been proven. These evidences, somehow, the & ouml; n & uuml; n & uuml; It started to grow. In the same year, television was invented by J. Baird. Flickering nozzles; r & uuml; nt & uuml; after a number, it is filtered. To begin with, Baird opted for mechanical discs; however, its competitors did various researches on TV and their focus was on electronic processing. After 1930, it started to protect the world with white goods.

Computers and the Internet

In 1940, G. Stibitz got used to using the teletypewriter on his son calculator in the United States and achieved successful results. Stibitz obtained the results of the totality calculation from another area. Host configuration was very popular in the 1970s. At that time, some researchers began to explore ways to send messages without using a central server. The results of these exercises should be considered as a solution. created a network. The number of these splits reached over 200 in 1980. With these developments, ARPANET was born. ARPANET and other networks gave birth to the Internet.

Companies that mediate general communications via telephone and the internet form part of the telecommunications community. The company has accelerated the infrastructural work to ensure the flow of information and data. Satellite companies, Internet provider companies or wireless operators are considered the most important group.
