Without the Internet, there would be no information age. But when everyone uses it, no one ever asks who invented it. Only a very few people know that the Internet was invented by high-energy physicists. The Internet was invented by a British scientist at the European Nuclear Center (CERN, also translated as the Western European Nuclear Center), his name is Tim Bernes-Lee. The background at that time was: several large-scale high-energy physics experiments were being conducted at CERN. As we all know, the research of high-energy physics requires extremely large and complex experiments, which often require the participation of many scientists, sometimes as many as hundreds. So many scientific and technical personnel often come from dozens of countries. Most of them spend part of their time at CERN and part or most of their time in their own countries. When preparing for the experiment, everyone divided their work to develop part of the experimental equipment in their own laboratories, and then installed it centrally at CERN. When the experiment is carried out, the experimental data obtained must be sent to everyone as soon as possible for everyone to share and analyze. The software used for analysis must be unified. If the software is modified, it must be unified. Any modifications to the software must be approved by everyone. Discuss the results obtained from the analysis. In the above series of processes, an extremely large amount of information must be exchanged as quickly and conveniently over long distances without loss. How to do this. In order to solve this problem, British scientist Berners-Lee put forward "Recommendations on Information Management" in 1989. The proposal said: "This proposal involves the management of general information for CERN's accelerators and experiments. The problem of information loss in complex and evolving systems was discussed, and a solution based on distributed hypertext was obtained." He used the "Hypertext protocol" to build the Internet (World Wide Web). His idea was realized in 1990, with the establishment of the Internet within the Western European Nuclear Center. In 1991, the Internet began to be used on the Internet. In 1993 Berners-Lee wrote a book called "Weaving the Internet." The book says: "This year (1993) Robert and I received a statement from CERN, signed by a director of the center and stamped with CERN's seal. The statement said that CERN allows anyone to Free use of the Internet's protocols and code to build servers or browsers for others to use or sell, without any copyright or other restrictions. "Berners-Lee also added a larger font after this sentence." The word "haha" means that he is very happy and agrees! There is a key issue here. Since CERN and Renners-Lee do not want patents, the Internet has become commonly used around the world. Bell invented the telephone and had a patent, so everyone knew Bell.
