What are the main services provided by the Internet?

The Internet provides the following four services:

Advanced WWW browsing service is provided on 1.Internet.

WWW (World Wide Web) service is a way to browse and query Internet information based on hypertext. It interactively queries and accesses information stored in remote computers, providing a single and consistent access mechanism for all kinds of Internet browsing and retrieval access. Web pages combine text, hypermedia, graphics and sound. Internet has brought convenience for enterprises to communicate and obtain information resources.

2. Provide e-mail service on the Internet.

E-mail is a communication method that provides information exchange through electronic means, and it is the most widely used service on the Internet. Through the e-mail system of the network, users can contact network users in any corner of the world at a very low price (no matter where they send them, they only need to pay the network fee) and in a very fast way (they can send them to any designated destination in the world in a few seconds).

3.3. Telnet service for remote login is provided on the Internet.

Telnet protocol is a member of TCP/IP protocol family, and it is the standard protocol and main mode of Internet remote login service. It enables users to complete the remote host work on the local computer.

4.4. FTP service for file transfer is provided on the Internet.

FTP is the abbreviation of English file transfer protocol and Chinese text transfer protocol. Used to control the two-way transmission of files on the Internet. At the same time, it is also an application. There are different FTP applications based on different operating systems, all of which follow the same protocol to transfer files. In the use of FTP, users often encounter two concepts: "download" and "upload". "Downloading" files means copying files from a remote host to your own computer; "uploading" a file means copying it from your own computer to a remote host.

Internet, officially translated as Internet in Chinese, is also called Internet. It is a global computer network, which uses a common language to communicate with each other. Once you connect to any of its nodes, it means that your computer is connected to the Internet. At present, Internet users have spread all over the world, and the number of people using the Internet has reached hundreds of millions, and the number of users is still growing at the same speed.

Extended data:

Characteristics of the Internet:

1. This system is not associated with a specific private network, and users can easily access any node on the network anywhere and at any time in the world.

2. The requirements for users' computer and network operation are very low;

3. Most messages are formed by filling in documents on the screen;

4. High Internet bandwidth;

The cost of internet is very low.

Network origin

Internet is formed on the basis of ARPANET, an early American military computer network, through continuous development and changes. The origin of the Internet can be divided into the following stages.

1. The embryonic stage of the Internet

1969, the United States Defense Advanced Research Projects Agency (ARPA) began to establish a network called ARPANET. At that time, the purpose of establishing this network was to build a computer network for military needs. When a part of the network is destroyed, the rest of the network will soon establish a new connection. It is generally believed that this is the embryonic form of the Internet.

2.2 development stage. internet

The National Science Foundation (NSF) began to establish the computer network NSFNET in 1985. NSF plans to establish 15 Supercomputer Center and National Education and Research Network to support national-scale scientific research and education NSFNET, and on this basis, realize the connection with other networks. NSFNET has become the backbone of the Internet, mainly used for scientific research and education, replacing the backbone of ARPANET. 1989 MILNET (separated from ARPANET) began to adopt the name Internet after it realized the connection with NSFNET. Since then, the computer networks of other departments have been merged into the Internet, and ARPANET has been dissolved.

3.3 commercialization stage. internet

In the early 1990s, commercial organizations began to enter the Internet, which made the Internet start a new commercialization process and became a powerful driving force for the great development of the Internet. 1995, NSFNET stopped operating, and the Internet has been fully commercialized.
