The development of Internet in china can be roughly divided into three stages:
The first stage is the piolt phase from 1986.6 to 1993.3. During this period, a number of scientific research departments and institutions of higher learning began to study Internet networking technology, and carried out research projects and scientific and technological cooperation. This phase of the network application is limited to a small area of e-mail service, but only a small number of institutions of higher learning and research institutions to provide e-mail services. Development experience as follows:1986: Dial up (Terminal) 1990: X.25 (1989.11: CNPAC, 1993.9: CHINAPAC) 1993.3: Leased Line (DECnet) (Email Only).
The second stage is the initial stage from 1994.4 to 1996. In 1994.4, Zhongguancun area of education and research network engineering model access to the Internet, and the Internet to achieve the TCP / IP connection, which opened a full-featured Internet services. Since then China has been officially recognized by the international community for the Internet nation. Later, ChinaNet, CERnet, CSTnet, ChinaGBnet projects such as the Internet throughout the country have been started, the Internet has begun to enter public life, and in China has been rapid development. By the end of 1996, China's Internet users has reached 200,000, the use of the Internet operations and application of gradually increasing.
The third The third phase, from 1997 to date, is the rapid growth phase. After 1997,the number of domestic Internet users remain the basic doubling every six months to maintain growth. Growth to this day, Internet users have more than 20 million. According to China Internet Network Information Center (CNNIC) released a statistical report shows that, by the end of June 30, 2001, China's total online computers about 10,020,000 units, of which line of online computers: 1,630,000 units, dial-up computer: 8,390,000 units, about 26.5 million Internet users, of whom the number of users access to the Internet line to 4,540,000, the number of dial-up users to 17,930,000, while the use of line with the number of dial-up users 4030000. In addition to the computer at the same time the use of other devices (mobile terminals, information appliances) The number of Internet users 1,070,000. CN domain names registered under 128,362, WWW sites 242,739, the international export bandwidth 3257Mbps.
1, Internet phased development of China's development of INTERNET to 1987 through the China Academic Network CANET first letter to the world, marked by E-mail. After decades of development, the formation of the four mainstream network system, namely: the Science and Technology, Chinese Academy of Sciences Network CSTNET; the Ministry of Education's Education and Research Network CERNET; the CHINANET former Ministry of Posts and Telecommunications Ministry and the original electronic GBN CHINAGBN. Internet in China, the development process can be roughly divided into three phases: the first phase for 1987-1993, but also study of the pilot phase. During this period a number of Chinese scientific research departments and institutions of higher learning began to study InternetInternet technology, and carried out research projects and scientific and technological cooperation, but at this stage of the network application is limited to a small area of e-mail services. The second phase from 1994 to 1996, the same is the early stage. In April 1994, Zhongguancun area of education and research network engineering model to enter the Internet, since China was officially recognized by the international community for the Internet nation. After, Chinanet, CERnet, CSTnet, Chinagbnet projects such as Internet network across the country one after another startup, Internet begun to enter public life, and in China has been rapid development. To the end of 1996, China's Internet users has reached 200,000, the use of Internet operations and application of gradually increasing.
