Modern technologies allow quick access to information. But sometimes it becomes interesting: how it all began, who stood at the origins and what path of development did the means of communication go.
A bit of history
Human development is impossible without the exchange of information. For several hundred years, mail remained practically the only way to deliver a message from point A to point B. However, with the discovery of electricity and electromagnetic fields, the situation began to change.
The emergence of wire and radio communications had a positive impact on the development of the world community. At the end of the 19th century, new means of data transmission appeared, which sharply increased the speed of information exchange over long distances. Moreover, a permanent connection between continents became possible. And yet, where did it all start?
Chronology of the development of communications
Telegraph. In 1837, William Cook introduces the first wired electric telegraph with its own coding system. Later, in 1843, the famous Morse code will present his development of the telegraph and develop his own coding system - Morse code. And already in 1930, a full-fledged teletype appeared, equipped with a telephone dialer and a keyboard like a typewriter.
Telephone. Alexander Bell patented in 1876 a device capable of transmitting speech over wires. By the way, the first telephones appeared in Russia in 1880. And in 1895 the Russian scientist Alexander Popov conducted the first radio communication session.
The discovery of the possibility of transmitting a signal by radio made a real revolution in the development of communications. Now it is possible to create a true global communication network. Indeed, with all the advantages of the first telephones and telegraphs, they had one drawback - wires. Now, thanks to the radio, it was possible to establish constant communication with mobile objects (ships, planes, trains) and establish intercontinental data transmission.
Pager and mobile phone. In 1956, the American company Motorola released the first pagers. This gadget has already been forgotten and is not used now, and once it was a breakthrough in the communications industry. In 1973, the first mobile phone from Motorola appears. It weighs more than a kilogram and has impressive dimensions.
Computer network. Serious development of computers began after World War II. Already in 1969, the first computer network, ARPANET, was created. It is generally accepted that this particular network served as the basis for the modern Internet.
Global information network. At the moment, all means and types of communication are combined into one global telecommunications structure. The development of modern technologies allows you to connect to the worldwide network from almost anywhere on earth and get access to any necessary information.
