the level of support distributed computing and incredibly easy to spread tabiruyutsya. Second, the protocol that establish ways the "web" is a very simple and at the same time allowing servers the frame was acceptable to cope with the extremely intensive traditional network timetable (flow data networks). In addition, much of the WWW realized the fact that dozens of years ago, people were predicting like Ted Nelson (Ted Nelson), in particular, interactive books, and hyperlinks.

Perhaps because of the birth of their Internet bound computer Science, it was always like a magnet, attracted by a talented hackers - programmers who for a variety of reasons (who sake of "sports interests sa, who in criminal purposes) vzlamyvayut other people's computer systems.
For example, November 2, 1988, thousands of computers together into the network, suddenly slowed dramatically speed. Many of them even briefly basis tanovilis. All data fortunately survived, but until administrators computer systems were trying to re-establish control over their machines, computer time worth millions of dollars have been squandered vpus- Oceano. It is in connection with this history and the first time the general public heard on the Internet. As it turned out later, was the cause of all the harmful a computer program, named "chervyakom." She transmitted on the network with one computer to another and incidentally "razmnozhalas" to copy itself. ( "Chervyakom" and not a virus called her because she did not infection other programs). unnoticed She enjoyed the "crevices" in the system software and receives direct memory access attacked her computers. There she hiding podsovyvala and incorrect data that CIS rudnyalo her identification and destruction. A few days later, The New Newspaper York Times identified the hacker, author of the program. Robert Morris-mladshy, dvadtsatitrehletny student last course of Cornell University, wrote that "chervyaka", and then released him to be free to slides back, to how many computers will be able to get it. However, the program typographical error, which made "Wurm became multiply much faster than expected. Morris applied to the Computer Fraud and Abuse Act (Act of computer fraud and deliberate inflicting harm) of 1986, and sentenced to three years of conditional imprisonment, a fine of 10000 dollars and 400 hour of community service.
And later in the Internet occurred all sorts accident happened problems Protection, but not so much that very often. As a result, Internet has become quite reliable communication channel for millions of people. By linking location objects after having servers worldwide, it provides for the exchange of electronic mail, messages for electronic whiteboards and other data. In the flow of information there is only so: korotenkih messages from a dozen letters to the huge Files from photographs and software packages. The value of services the server, a remote thousands of kilometers, is no higher fees what is in any kilometer away from you.
The model for pricing Internet has already changed the presentation of the that price communication services directly depends on the time and distance of. The same thing happened with computer technology. Previously, if you unable to afford a large computer, it had to rent time per hour. And the emergence of these PCs troublesome freed.
