The main traditional service functions of the Internet:

1. Remote login service Telnet (Remote Login)

Remote login is one of the basic information services provided by Internet, and it is a terminal simulation protocol that provides remote connection services. It enables your computer to log in to another computer on the Internet. Your computer becomes a terminal of the computer you log in to, and you can use the resources on that computer, such as printers and disk devices. Telnet provides a large number of commands that can be used to establish an interactive dialogue between the terminal and the remote host and enable local users to execute the commands of the remote host.

2. File transfer service FTP

FTP allows users to transfer files between computers, and the types of files are not limited, can be text files or binary executable files, sound files, image files, data compression files, and so on. FTP is a real-time online service. Before doing work, you must log in to the other party's computer before you can search for files and transfer files. The ordinary FTP service needs to provide the corresponding user name and password when logging in, and the FTP service cannot be used when the user does not know the user name and password of the other computer. To this end, some information service organizations provide an "anonymous FTP service" in order to facilitate Internet users to use their publicly published information through the Internet.

3. Email service E-mail (Electronic Mail)

E-mail is like a letter from a post office, but it is different in that it is a fast, simple, efficient and inexpensive modern means of communication with other users through Internet. And it has many advantages, such as E-mail is much faster than sending letters through traditional post offices, and the rate of loss and damage of letters is very small without intentional sabotage by hackers.

4. World wide Web WWW (World Wide Web)

The Chinese translation of WWW (World Wide Web) is the World wide Web or World wide Web. WWW is created to solve the problem of information transmission on Internet. Before the creation of WWW, almost all information was published through E-mail, FTP, Telnet and so on. However, because the information on the Internet is scattered everywhere, it is impossible to search the information unless you know the location of the information you need. It uses hypertext and multimedia technology to link different files through keywords and provides a way of cross query. In a hypertext file, one keyword links to a file related to another keyword, which can be on the same host or on another host in Internet, as well as another hypertext file
