The development of the Internet began during the Cold War. At the end of 1960s, due to the global hegemony of the United States and the Soviet Union, in order to prevent the influence of nuclear war on its own communication system, the United States began to study how to prevent nuclear strikes. This is also the most basic concept of Internet research-after a nuclear attack, communication can be quickly restored and kept uninterrupted.

Internet was a military system at the beginning of its development, and then it developed and gradually expanded its application. At first, four universities were interconnected, and later it was expanded to 13, forming a secondary root server with 10 locations in the United States. After that, although the Internet was applied to education and scientific research departments, its rapidity and convenience made more and more departments, including many government departments, apply it. After the commercial sector began to participate, the trend of Internet commercialization was inevitable.

There are many business models and types of Internet, but relatively speaking, there are mainly the following business value chains: traditional business access services provided by telecom operators; Online games, a series of service providers, including online game service providers, game operators and telecom operators, form a value chain.

The problem of network security should be very serious, such as hacking, network theft, network fraud and network virus. The operation of network operators has formed a relatively fixed concept, which is more secure.

Online behavior should also be gradually standardized. This concept of freedom, no management and no law in American Internet is still deeply rooted in people's hearts and the world. Everyone once thought that any behavior on the internet should not be regulated and should not be regulated. The problems that appear now make people realize more and more that it is really necessary to regulate and manage online behavior. Online behavior should also abide by the moral norms in real life and be bound by the rules of real society. Internet abuse takes advantage of the excellent characteristics of the Internet, and practitioners, industry organizations and the government need to take further actions.

The obvious trend in the future is the popularization of broadband services and various mobile terminals. The construction and application of full broadband will further promote the overall development of the network. The mode of Internet operation and survival will also be more abundant. Nowadays, people mostly browse information, use chat tools and play online games on the Internet, and regard the Internet as an advanced information technology toy. With the development of the Internet, toys can become tools and indispensable tools for people's daily life and work. The application of the network is also more open. Many government websites put government affairs on the website, such as soliciting opinions and local grassroots elections, which makes the application of the network more open and diversified. I hope that network information should be people-oriented. As an information platform, more than 50% of its users are teenagers under the age of 30, so the network built for teenagers should be credible and healthy, and should become friends and assistants in the process of teenagers' growth. Network education will be the next hot spot of Internet business. Internet search, large-capacity e-mail, e-commerce platform, mobile Internet, wireless local area network, network resource information development and other services will all become hot spots in Internet commerce.
