The development of Internet:

1. Internet was originally developed from ARPANet. In a sense, Internet is the product of the Cold War between the United States and the Soviet Union. In 1969, the Defense Advanced Research projects Administration (ARPA--AdvancedResearchProjectsAgency) began to build a network called ARPAnet, connecting several military and research mainframes in the United States. At the beginning, ARPAnet was only connected to four hosts, which was under the protection of top secrets of the US Department of Defense in terms of military requirements, and technically it did not have the conditions to promote it to the outside world.

2. In 1983, ARPA and the Communications Bureau of the US Department of Defense successfully developed the TCP/IP protocol for heterogeneous networks. The University of California, Berkeley took the protocol as a part of its BSDUNIX, which made the protocol popular in the society, thus giving birth to the real Internet.

3. In 1986, the National Science Foundation (NationalScienceFoundation,NSF) made use of the TCP/IP communication protocol developed by ARPAnet to establish the NSFnet wide area network, the father of the ARPAnet-- network, on the basis of five scientific research and education service supercomputer centers, which was gradually replaced by NSFnet. By 1990, ARPAnet had retired from the stage of history.

4. In 1989, WWW was successfully developed by CERN, which laid the foundation for Internet to intercept / retrieve wide-area hypermedia information.

5. By the early 1990s, Internet had in fact become a "network". Each subnet of ── was responsible for its own erection and operation costs, and these subnets were connected by NSFnet. The users of Internet were no longer limited to computer professionals, and gradually used Internet as a tool for communication and communication, rather than just sharing the computing power of NSFnet supercomputers.

6. In 1991, three American companies operated their own CERFnet, PSInet and Alternet networks respectively, which could provide Internet networking services to customers to a certain extent. with the emergence of Internet commercial service providers, industrial and commercial enterprises could finally enter Internet openly, and countless enterprises and individuals around the world poured into Internet one after another, bringing a new leap in the history of Internet development.
