The Rise of International Internet

Source: Shangpin China | Type: website encyclopedia | Time: 2015-09-12
Following the penetration of personal computers into homes and offices in the mid-1980s, the Internet began to spread explosively around the world in the mid-1990s. The impact and impact of the Internet and the accompanying e-commerce and digital economy on the current society are unmatched by any technology and production tool in human history. Then why is the Internet so powerful? Where did the Internet come from? It is necessary for us to understand the situation of the Internet in the United States, because the United States is not only the birthplace of the Internet, but also the most developed region in the world.

The origin of the Internet came from an academic research commissioned by the US Department of Defense to Stanford University in the late 1960s. Its main content is how to ensure that the US can effectively use the military command system even after an accidental nuclear attack. According to this requirement, the designed network should be decentralized and centerless, and each node on the network can become a command and control center with the ability to generate, receive and transmit information. The information on the network is decomposed into "packages" at one node and numbered. After being transmitted to another node, it is assembled and restored. As a result, after information is decomposed into packets, each packet can be transmitted through different paths. In this way, even if some nodes or communication lines are destroyed, packets can still be transmitted through other paths and sent to the destination. Therefore, the Internet is a system without a central control point. Its developers believe that systems with central control points will bring unpredictable system error risks in a series of events, such as enemy attacks, natural disasters and human errors. Therefore, the system has become a truly decentralized network, and the network protocol has been developed into an "open system" environment, enabling information to pass through fundamentally different network platforms. No one thought that this design idea had created the Internet.

According to this design idea, the Advanced Research Projects Agency of the US Department of Defense established ARPANET, which only connected four computers at that time. In the mid-1980s, ARPANET was divided into two parts: defense related network DOD and unrelated network. Then the National Science Foundation of the United States was appointed to manage civil network research. The National Science Foundation (NSF) funded and leased the communication lines of MCI Corporation, connected five supercomputer centers in the United States, and established NSFnet. After further upgrading and acceleration, NSFnet is open to the public and becomes the most important backbone of the Internet. When TCP/IP became the communication protocol standard of ARPANET in 1983, the Internet was finally born Website construction Internet securities and e-commerce have also emerged in succession.

In fact, the Internet can be logically defined as a global information system connected together based on TCP/IP protocol through a globally unique address. It includes thousands of interconnected computer systems. Initially, the Internet was restricted to research and education NSF usage regulations do not allow it to be used for commercial purposes, however, given the political pressure to establish an information highway and develop organizations and find information user-friendly tools. This usage regulation has become difficult to enforce. It was not until 1993 that the Internet was opened to business. By 1995, the network developed in the late 1960s had connected 48000 different networks and 350 million users in 160 countries. At present, the Internet is at the beginning of its own growth and large-scale market popularization cycle. Two major developments in the early 1990s drove their growth, namely the emergence of the World Wide Web (WWW or simply the Web), and the subsequent invention of graphic based web browsers such as Netscape's Navigator or Microsoft's Internet Explorer. Today, the Internet has brought together all businesses such as telephone, fax, computer, radio and television.
