The Internet (Internet) is a collection of global information resources. There is a rough saying that INTERNET is a logical network formed by the interconnection of many small networks (subnets), and several computers (hosts) are connected in each subnet. For the purpose of exchanging information resources, Internet is based on some common protocols and is formed through many routers and the public Internet. It is a collection of information resources and resource sharing.

The most basic services provided by Internet

1. WWW service

WWW (World Wide Web) service is a way of browsing and querying Internet information based on hypertext. It queries and accesses information stored in remote computers interactively, providing a separate and consistent access mechanism for a variety of Internet browsing and retrieval access. Web pages combine text, hypermedia, graphics, and sound. The Internet brings convenient conditions for enterprises to communicate and obtain information resources.

2. Email E-mail service

E-mail is a way of communication that provides information exchange by electronic means, and it is the most widely used service on the Internet. Through the network's e-mail system, users can contact Internet users anywhere in the world at a very low price (no matter where they are sent) and in a very fast way (they can be sent to any designated destination in the world in a few seconds).

3. Log in to Telnet service remotely

Remote login service is also known as Telnet service, which is one of the earliest service functions provided in Internet, and many people are still using this service function.

Telnet is a protocol of Internet remote login service, which defines how remote login users interact with the server. Telnet allows users to log in to a remote time-sharing system on a networked computer and then use the remote system as if they were their own computer.

To use the Telnet service, you must start a client application on the local computer, specify the name of the remote computer, and establish a connection to it through Internet. Once the connection is successful, the local computer, like a normal terminal, directly accesses the resources of the remote computer system. The remote login software allows the user to interact directly with the remote computer, through the keyboard or mouse operation, the client application sends the relevant information to the remote computer, and then the server returns the output to the user. After the user exits the remote login, the keyboard and display control of the user returns to the local computer. General users can log in remotely through Windows's Telnet client program.

4. File transfer FTP service

Text transfer service, also known as FTP service, is one of the earliest service functions provided in Internet, and it is still widely used.

FTP (File Transfer Protocol) protocol is the basis of file transfer on Internet, and FTP is a service based on this protocol. The FTP file transfer service allows users on Internet to transfer files from one computer to another, and almost all types of files, including text files, binary executables, sound files, image files, data compression files, etc., can be transferred using FTP.

FTP is actually a set of file transfer service software, which takes file transfer as its interface and uses simple get or put commands to download or upload files, just like executing file copy commands on Internet. Most FTP server hosts use Unix operating system, but ordinary users can easily use FTP through Windows95 or Windows 98.

The most important feature of FTP is that users can use many anonymous FTP servers on Internet. The so-called anonymous server refers to the system that can be accessed without a special user name and password. When users connect to an anonymous FTP server, they can log in with "anonymous" as the user name and their E-mail address as the password. After a successful login, the user can download the file from the anonymous server. The standard directory for anonymous servers is pub, where users can usually access files in all subdirectories. For security reasons, most anonymous servers do not allow users to upload files.

5. Usenet network newsgroup service

Usenet is a collection of various discussion groups organized by many like-minded users. It is also commonly referred to as the global bulletin board system (BBS). Usenet is used to publish bulletins, news, comments and various articles for online users to use and discuss. The discussion is organized according to different topics, each of which is divided into a special topic group, called the newsgroup, and more sub-topics can be divided within it.

Each Usenet news is guided by a type-specific tag, and each newsgroup revolves around a topic, such as comp. (computer content), news. (Usenet's own news and information), rec. (sports, art and entertainment), sci. (science branch), soc. (social issues), talk. (discussion and communication), misc. (other miscellaneous topics), biz. (business issues), etc.

Users can not only choose to join the thematic groups they are interested in, but also set up new thematic groups themselves. As long as someone participates, the thematic group can continue to exist; if no one attends for a period of time, the thematic group will be automatically deleted.

6. Electronic bulletin board service

BBS (Bulletin Board Service, bulletin board service) is an electronic information service system on Internet. It is a popular means of communication between individuals and groups in contemporary times. Today, BBS has formed a unique online culture. Netizens can express their thoughts and ideas freely through BBS.

BBS is actually a kind of website. From a technical point of view, electronic bulletin board is actually a public information storage area set up in a computer on the network in a distributed information processing system. Any legitimate user can access information in this storage area through Internet or local area network. In the early days, BBS could only provide plain text forum services, and BBS could also provide email, FTP, newsgroups and other services.

BBS is divided into several columns according to different topics, and the division of columns is set up according to the needs and preferences of most BBS users. The right to use BBS is divided into browsing, posting, emailing, sending files, chatting and so on. Almost any Internet user has the right to browse freely, and only officially registered users can enjoy other services.

The biggest difference between BBS and Internet is that, as its name describes, it is a "bulletin board", that is, the vast majority of e-mails running on BBS sites are public letters.

Therefore, users will be faced with almost all the information on the site. Internet in China first developed from universities and scientific research institutions, and colleges and universities have generally set up campus networks. therefore, students and teachers have naturally become the largest users of BBS.
