What is a global network?

Almost everyone today is familiar with the Internetby hearsay. The Internet in the modern world plays an important role and is simply necessary for mankind. On the question of what a global network is, many people know the answer. At its core, the global network is the union of a large number of computers that can work at a distance.

At the moment, there are rules by whichcomputers can communicate with each other. All this can be done only with the help of the World Wide Web. So what is a global network-Internet? The Internet assumes the same way for all computers to connect to the global network, a single coding for data transmission and a single system for identifying data.

What is the system for?

This system was created, first of all,so that people from all corners of the earth have a constant opportunity to communicate with each other, and that at the same time some disruptions in the system are not fatal. To understand what a global computer network is, just imagine the web. In the middle of the web, weaving is known to be more dense - these are the so-called host computers that constantly receive and send data that come to them from different ends of the web. Since there are a lot of host computers, neither viruses, hacker attacks, nor power outages can ever "put" such a global network.

If some host computer suddenly stopswork, then all data is automatically forwarded to another host, so that all data remains secure. There is a huge number of host computers in the modern global network, and the number of users connected to them is even greater, although probably no ordinary person, going to the Internet, even imagines which part of the global system he is becoming.
