Do you know how the Internet works?

How does the Internet work? An interesting fact: the Internet was born only during the Cold War as a project of an American military research organization called ARPA. Developers were tasked to: somehow technologically connect military computers with each other so that the network continued its correct work even in the event of the outbreak of nuclear war or the disruption of most of the communication centers. The topology called "star" was immediately discarded, it is possible to build a network, but if the central node were to be disrupted, then the connection would be lost and the network would stop working. It was also impossible to connect each individual computer using separate lines, because too many resources would have to be used.

The researchers spent a lot of time, but still managed to find a brilliant solution to this problem. That's what they did: they connected the computers to the network and connected them to each other with several communication channels. In this case, the information was transmitted over the network by packets (i.e., portions) between the designated nodes. One such packet contains all the information about the destination and moves directly to the target by another node, while finding the shortest path. In the event that the communication channel that provided the shortest route was disabled or inactive, the information traveled along a different, longer but more active path that worked correctly. But the most important advantage in this model is that there is no control center, therefore it was extremely difficult and practically impossible to disable the whole system. If someone asks how the Internet is arranged, then it's safe to answer - like a web.

After a while, American universities were connected to such a network, which at that time were engaged in research on defense technologies, then organizations in allied countries, followed by various commercial organizations. Broadband Internet has conquered the whole world with its simplicity and convenience of information exchange.

It is thanks to the decentralization of its structure and the absence of the main control center for the "web" that the worldwide Internet has become so popular. At the moment there is no developed country that does not use all its advantages, but if there was some central element in this system, no one would be interested in such a project.

After all, if you analyze: which corporation would develop an internal computer network, if competitors did not need to figure out how the Internet is arranged, get the main console to disconnect everything and disable it. In this case, the enterprise would risk stopping production and disrupting the timing, and in the worst case scenario, leakage of confidential information.

A vivid example of the durability of the modern web of the Internet: during the hostilities of the United States against Iraq, the United States tried to disable or restrict access to the Internet for Iraqis. What was the result of this? Nothing. Although the bodies that coordinate the work of the entire network are located in America.

The next advantage of the Internet is the cost. The work of the network is provided by the latest technologies, which give the cheapness of this service in most countries of the world.

The Internet network can be called a random invention, which was not designed for public consumption by all population groups of most countries around the world. Its popularity, it earned by simplicity, banality and the way the Internet is arranged: there is no center for managing all processes - there are no problems. Moreover, many people, when they go on vacation, are sure to check whether they have Internet access at the hotel so that they can contact their relatives and friends.
