In the 60s, American scientists created a prototype of the modern Internet, which was called "ARPANET". It was developed for communication between military facilities in case of a global war. In those years, the Cold War between the US and the USSR was not at its peak. Over time, the virtual network became available not only to the military, but also to scientists. Thanks to this, the government managed to link the largest universities in the state. In 1971, the first email protocol was created. A couple of years later, the World Wide Web covered not only the expanses of America, but also a number of other countries. The Internet was still available only to scientists who used it to conduct business correspondence. In 1983, the TCP / IP protocol known to everyone today was standardized. After 5 years, programmers developed a chat where users could communicate online. Although we owe the emergence of the Internet to the United States, the very idea of ​​creating the Web (WWW) originated in Europe, namely in the famous organization CERN. Briton Tim Berners-Lee worked there, who is considered to be the founder of the traditional Internet. After the Internet became available to anyone in May 1991, scientists were tasked with creating convenient tools for surfing. As a result, a couple of years later, the first full-fledged Mosaic browser appeared, displaying not only text, but also images. It was then that the number of Internet users began to increase exponentially.
