As early as the 60s of the 20th century, American computers began to be used not only in production and scientific research, but also in the field of national defense. Hence the "arpanet". Later, it was divided into military and civilian parts, and "network protocol" (IP) was used.
The Internet was built on this basis, hence the name.
The Internet has provided people with new and diverse means of communication. At present, there are 100 million Internet users in the world, and the Internet has entered many fields such as personal communication, education, news, entertainment and business. Among them, e-mail is currently a popular means of personal communication, and it is also the most used function by Internet users.
The greatest contribution of the Internet to scientific research, journalism, education, medical care, and other fields is the sharing of resources, including information resources, computer computing power resources, and storage power resources. It is precisely on the basis of this outstanding feature of the Internet that these fields have been networked the earliest and fastest. According to statistics, the annual growth rate of Internet users is between 15 and 20 percent.
The rapid spread of the Internet has become a new business hotspot. At present, the total volume of online commerce has exceeded $10 billion and is expected to reach $220 billion by 2001. The Internet intemet is the prototype and testing ground of the future information superhighway.
In recent years, the number of Intemet users has increased exponentially, and there are more than 10 million computers in Intemet, which shows its size.
Intemet is a global computer network that communicates in a common language, which means international internet. It's similar to an international** system – no one owns or controls the entire system, but connects it in the same way that a large network works. On the Internet, the WWW provides a graphical and accessible interface for users to view documents, and these documents and the links between them form an information "web", and the files or pages on the WWW are connected.
Linking other pages by clicking on a specific text or image is called a hyperconnect. Pages contain text, images, sounds, animations, and more. By placing these pages on a computer anywhere in the world, they can be accessed worldwide via the Internet.
The Internet has the following characteristics:
1) Intemet users and applications do not need to know the details of the hardware connection, and can hide the low-level nodes of the internetwork for users.
2) Able to send and receive data and information through the intermediate network.
3) All computers in the internetwork can share a global identifier, that is, a collection of names or addresses.
4) It is not necessary to specify the topology of the network interconnection, especially when adding a new network, it does not require full interconnection and does not require strict star connection.
5) The user interface is independent of the network, that is, a series of operations to establish communication and transmit data, which have nothing to do with low-level network technology and the host.
In short, the Internet network is logically unified and independent, and physically it is made up of different networks interconnected. Therefore, its users do not care about the connection of the network, but only the rich resources provided by the network.
