The birth of the Internet
The birth mission of the Internet: to improve the quality of human life around the world through various Internet services.
Make human life more convenient and rich, thereby promoting the progress of global human society. And it enriches the spiritual and material world of mankind, allowing mankind to obtain information most conveniently. Find what you are looking for and make human life happier.

With the advent of the world's first electronic computer in more than ten years in 1946, it was very expensive. There are very few computers. Its form is to directly connect a computer to several terminals through communication lines. We can also regard this method as the simplest prototype of a local area network.

From 1977 to 1979, ARPAnet introduced the TCP/IP architecture and protocol in its current form.

Around 1980, all computers on ARPAnet began to convert the TCP/IP protocol. Moreover, computers at this stage established the early Internet with ARPAnet as the backbone network.

In 1983, all ARPAnet computers completed the conversion to TCP/IP and implemented TCP/IP on UNIX (BSD4.1). ARPAnet's greatest technical contribution is the development and application of the TCP/IP protocol. Two famous science education networks, CSNET and BITNET, appeared successively.

1984. National Science Foundation NSF. They plan to establish 13 national supercomputing centers and a national education science and technology network. It later replaced ARPANET as the backbone.

In 1988, the Internet began to open to the outside world.
In June 1991, among the computers connected to the Internet, commercial users exceeded academic users for the first time. This was a milestone in the history of the development of the Internet. From then on, the growth rate of the Internet was out of control.

In the 21st century, network platforms are used in the field of e-commerce. Online merchants have become a trend.



Development Stage
First Generation: Remote Terminal Connection
early 1960s
Terminal-oriented computer network
Communication between subnets is not possible.

Second generation: computer network stage (local area network)
mid-1960s
Implement communication between computers.
Including: communication subnet, user resource subnet.
End users can access the software and hardware resources of the local host and all hosts on the communication subnet.
Circuit switching and packet switching.
The third generation: computer network interconnection stage

(WAN, Internet)
Developed by the International Organization for Standardization (ISO) in 1981. The Open System Interconnection Basic Reference Model (OSI/RM) enables interconnection between computers produced by different manufacturers.
The birth of the TCP/IP protocol.
The fourth generation: information highway (high speed, multiple services, large data volume)
Broadband Integrated Services Digital Network: Information Superhighway.
ATM technology, ISDN, Gigabit Ethernet
Interactivity: high-speed and visualization of online TV on demand, video conferencing, video phone, online shopping, online banking, online library, etc.

The staged development of the Internet
Three stages of the development of the Internet in China:
The first stage is from 1987 to 1993, which is the research and experimental stage.
During this period, some scientific research departments and universities in China began to study Internet technology. China has carried out scientific research projects and scientific and technological cooperation.

The second stage is from 1994 to 1996, the initial stage.
In April 1994, the Zhongguancun Area Education and Scientific Research Demonstration Network Project entered the Internet. Since then, China has been officially recognized internationally as a country with Internet. After that, several Internet network projects such as CERnet, CSTnet, CHINAnet, and CHINAgbn were launched nationwide. The Internet began to enter public life and developed rapidly in China.

The third stage, from 1997 to the present, is the fastest developing stage of the Internet in our country.
The number of domestic Internet users has basically maintained a growth rate of doubling every six months since 1997.

With the improvement of network foundation, the adoption of new technologies in user access, the diversification of access methods and the improvement of operator service capabilities. The bottleneck problem caused by the slow access network speed will be further improved. Internet speed will be faster. This will promote more applications to be implemented online.
