What is the Internet

The Internet is a world-wide computer network that unites many local networks and individual computers. Information stored in a variety of local networks and in separate computers connected by the Internet forms a kind of giant electronic library, access to resources for individuals and businesses can be either paid or completely free. Now it is clear what the Internet is.

The amount of data stored on the Web and distributed between the networked computers connected to the Network is so large that it is sometimes difficult to access them - this is because the necessary information can simply be lost in the whole ocean of other information - useful, useful and absolutely Useless.

To facilitate the search for necessary information, there are so-called search engines (Search Engines), which use the search algorithm among a significant number of documents for keywords. Yandex and Rambler are the most known among the search engines in the Russian part of the Internet, and Yandex provides a huge number of additional services for webmasters, including the keyword statistics service, and for "ordinary" users who can use the postal service or Yandex payment system - Money is along with other modern electronic services.

To the question "What is the Internet", one can give the following answer: The Internet is the most dynamic and rapidly developing system of information exchange in history. The Internet never stands still, the number of users is constantly growing. This is largely due to the emergence of the possibility of access to the Internet through mobile phones and modern televisions.

And when did the Internet appear? How did this happen? The Internet appeared as the result of strictly secret research conducted by the United States Department of Defense in order to develop and test methods that would help computer networks survive in the event of hostilities. The very first such network was ARPAnet, which brought together three networks in the state of California and a network in Utah. The union did not happen just like that, but following a certain set of rules, which was called the IP - Interne Protocol or, in Russian, the Internet protocol.

In the year of 1972, universities and research organizations got access to the Network, ARPAnet grew somewhat and began to unite already 50 universities and research organizations that were contracted by the United States Department of Defense. Already in 1973 the network became international. At the same time networks were united in England and in Norway. That's when the Internet appeared.

The emerging WWW, otherwise known as the World Wide Web or the World Wide Web, gave a powerful impetus to the further development and popularization of the Internet. The system of hypertext documents that appeared at the same time made the journey through the Internet a fast, understandable and safe.

In general, the idea of transferring documents through hypertext appeared in the sixties and was proposed by Ted Nelson, but at that time it was not implemented, because the level of development of computer technology could not in any way facilitate its implementation. That's about when the Internet came.

What is now understood by the term WWW, or rather, its foundations, was laid by Tim Berners-Lee at the time when he was working on the creation of a hypertext system, which resulted in the appearance of the very first text browser, which allowed viewing text files related to each other With other hyperlinks. In 1991, access to the browser was provided to the general public, but only outside of scientific circles the browser spread very slowly.

Now what is the Internet is known not so much by many, but, perhaps, by all. When it comes to what is the Internet, immediately refer to the most popular and most common services, among which, as the definition of the Internet says, the most important are e-mail, search, browsing and downloading to your computer A variety of multimedia information using one of the available browsers on the market, e-commerce and on-line real-time communication.

It is possible to define Internet or WWW, which is almost identical, and therefore in speech it is used almost identically, approximately as an association of distributed in the world through the Network of multimedia and text files and various services in such a way that they become available for universal access. That's what the Internet is.
