Question 2: The Internet provides the main services that are Remote login service (Telnet): Remote login is one of the basic information services provided by the Internet, is a terminal emulation protocol to provide remote connection services. It enables your computer to log in to another computer on the Internet. Your computer then becomes a terminal on the computer you are logged on to, and can use resources on that computer, such as printers and disk devices, etc. Telnet provides a large number of commands that can be used to set up an interactive dialog between a terminal and a remote host, and that can enable a local user to execute commands from the remote host.
File Transfer Service (FTP): FTP allows users to transfer files between computers, and there is no limit to the type of file, which can be a text file or a binary executable file, a sound file, an image file, a data compression file, and so on. FTP is a real-time on-line service, and you must log in to the other side of the computer before you can work on it. FTP is a real-time on-line service. Ordinary FTP service needs to provide the corresponding user name and password when logging in, when the user does not know the user name and password of the other computer will not be able to use FTP service. For this reason, some information service organizations in order to facilitate Internet users through the network to use their publicly available information, to provide an "anonymous FTP service".
E-mail service (E-Mail): E-mail is like a letter from the post office, but it is different in that e-mail is a fast, simple, efficient, inexpensive and modern means of communication with other users through the Internet. And it has a lot of advantages, such as E-mail than through the traditional post office mail letter to be much faster, at the same time in the absence of hackers deliberately destroy the situation, the letter loss rate and damage rate is also very small.
Network news service (Usenet): Usenet is a *** by many users of similar interests *** with the organization of a variety of discussion groups ***. Usenet is also commonly referred to as a global electronic bulletin board system (BBS). Usenet is used to publish announcements, news, reviews and articles for online users to use and discuss.

In addition, the user can also be e-mailed to subscribe to electronic magazines on the Internet, access to the required documents, participate in the relevant announcements and discussion groups.
3. Text Transfer Protocol (FTP)
The File Transfer Protocol (FTP) is the basis for file transfers on the Internet, and what is commonly referred to as FTP is a service based on this protocol.The FTP text transfer service allows users on the Internet to transfer files from one computer to another. Almost all types of files, including text files, binary executables, sound files, image files, data compression files, and so on, can be transferred using FTP.
FTP is actually a set of file-serving software that uses file transfer as an interface, and uses simple get and put commands to download and upload files, just as it does for file copy commands on the Internet. Most FTP server hosts use the UNIX operating system, but ordinary users can easily use FTP and UNIX hosts to transfer files through Windows 98 and Windows XP.
The best feature of FTP is that users have access to numerous anonymous FTP servers on the Internet. The so-called anonymous servers refer to systems that can be accessed without a specialized username and password. When connecting to an anonymous server, users can log in with Anonymous as their username and their e-mail address as their password. Once logged in, users can download files from the anonymizer. The standard directory of an anonymous server is pub, and users can usually access files in all subdirectories of that directory. For security reasons, most anonymizers do not allow users to upload files.
4. Telnet
Telnet is a protocol for a remote login service that defines how a remote login user interacts with a server. It allows a user to log on to a remote timesharing system from a networked computer and then use that remote system as if it were his or her own computer.

8. other information services (Talk, IRC, MUD)
1. Telnet services
2. Telnet
Remote-login is one of the most basic information services provided by the Internet. Remote-login is the process of making a local computer temporarily become a remote computer emulation terminal under the support of the network communication protocol Telnet. To log in on a remote computer, you must be a legitimate user of the computer system and have the corresponding account number and password. When logging in, you should give the domain name or IP address of the remote computer and enter the user name and password according to the system prompts. After logging in successfully, the user can actually use the system's open functions and resources, such as: **** enjoy its hardware and software resources and databases, the use of its information services provided by the Internet, such as: E-mail, FTP, Archie, Gopher, WWW, WAIS, and so on.
Telnet is a powerful resource **** enjoyment tool. Many university libraries provide online search services through Telnet, and some *** departments and research organizations also open their databases to the public so that users can search through Telnet.
2. File Transfer Service (FTP)
File transfer refers to the transfer of files between hosts on a computer network, which is carried out under the auspices of the network communication protocol FTP (File Transfer Protocol).
Users generally do not want to browse files stored on a computer remotely online, and are more likely to fetch these files back to their own computers first, which not only saves time and money, but also allows them to read and process these fetched files comfortably.
The Internet provides a file service, FTP, which is designed to satisfy this need. The Internet provides a file service called FTP that meets the needs of users. Two computers on the Internet are geographically separated by a distance, and as long as both support the FTP protocol, users on the Internet can transfer files from one computer to another.
FTP is a real-time online service similar to Telnet. To use the FTP service, the user must first log on to the other computer, and unlike remote login, the user can only perform operations related to file search and file transfer. With FTP, you can transfer any type of file, such as text files, binary files, image files, sound files, data compression files, and so on.
Ordinary FTP services require users to provide the appropriate username and password when logging on to a remote computer. Many information service organizations provide a service called Anonymous FTP to make it easier for users to access their published information over the network. Users do not need to register or create a username and password before logging in to such FTP servers. Instead, they can use anonymous as their username, and generally use their e-mail address as their password.
Anonymous FTP is one of the most important Internet services. Many anonymous FTP servers have free software, e-magazines, technical documents, and scientific data for people to use. The FTP server can be used to provide free software, e-magazines, and scientific data, etc. The anonymous FTP server has some restrictions on the user's permission to use the service: Usually, the user is only allowed to access the files, but not allowed to modify the existing files or transfer files to it; in addition, there are some restrictions on the scope of the files that the user can access. In order to make it easier for users to access very long files or groups of files, in anonymous FTP servers, files are pre-compressed or packaged. Users should have the ability to compress and restore files, as well as pack and unpack files when using these files.
3. E-Mail
Electronic Mail, also known as e-mail, is a service that allows users or groups of users to send and receive information over a computer network.
