What is the World Wide Web (WWW)

WWW is the abbreviation of World Wide Web (Global Information Network), which can also be referred to as Web. The Chinese name is "World Wide Web".

WWW (World Wide Web) is a global information "spider web" attached to the Internet, inlaid with countless information in the form of hypertext, among which there are bright pearls, and of course there are Rancid garbage. Some call it the Global Web, some call it the World Wide Web, or simply the Web (the National Committee for the Approval of Scientific and Technical Terms recommended that the Chinese translation of WWW be "World Wide Web"). WWW is currently the most popular, popular and latest information retrieval service system on the Internet. It connects all existing resources on the Internet, allowing users to provide hypertext media resource documents on all sites on the Internet that have established WWW servers. This is because WWW can seamlessly integrate various types of information (still images, text sounds, and audiovisuals). WWW not only provides fast information search through a graphical interface, but can also connect with other servers on the Internet through the same graphical interface (GUI).

Since the WWW provides people all over the world with a means to find and share information, it can also be regarded as a research hotspot of various organizations, scientific research institutions, universities, and companies around the world. Developed information collection. It is based on Internet queries. Information distribution and management systems are dynamic formats for multimedia communications in which people interact. Its formal formulation is: "A primitive protocol for wide-area hypermedia information retrieval, aimed at accessing huge amounts of documents." What WWW has achieved is to provide users on computer networks with a compatible means to access various media in a simple way. It was the first truly global hypermedia network, changing the way people viewed and created information. As a result, the whole world quickly set off a huge upsurge in research, development and use of WWW.

WWW was born in the Internet, and later became a part of the Internet. Today, WWW has almost become synonymous with the Internet. Through it, everyone who joins it can reach every corner of the world in an instant. Just plug a phone line into your PC (it may be a laptop you carry with you plus a mobile phone). At this time, the world's information Right at your fingertips!

WWW does not actually exist anywhere in the world. In fact, users of WWW give it new meanings every day. Citizens of the Internet society (including institutions and individuals) embed all kinds of information they need to make public into the WWW in the form of a homepage. In addition to text, the homepage also includes graphics, sounds and other media forms; and the content is drawn from various sources. From job advertisements to electronic Bibles, it can be said to be all-inclusive and everything-inclusive. The main form of the home page published on the Web is some HTML text (HTML is Hyper Text Markup Language, Hyper Text Markup Language).

Since the 1940s, people have dreamed of having a world-wide information database. Not only can data in this database be accessed by people around the world, but it should also be easily linked to information elsewhere so that users can obtain important information quickly and easily. It triggered the fifth information revolution.

With the rapid development of science and technology, this dream of people has become a reality. The most popular system currently in use is called "World Wide Web" (World Wide Web). Its official definition is "WWW is a wide-area hypermedia information retrieval initiative to give universal access to large universe of documents." In short, WWW is an Internet-based computer network that allows users to Access information on another computer over the Internet.

From a technical point of view, the Global Information Network is a collection of clients and servers on the Internet that support the WWW protocol and the Hyper Text Transport Protocol HTTP (Hyper Text Transport Protocol). Through it, hypermedia files and content from all over the world can be accessed. Including text, graphics, sounds, animations, databases, and a variety of software.

Theoretically, the Global Information Network includes the entire Internet world with more than 200 million people. It includes all Web sites, Gopher information stations, FTP archives, Telnet public access accounts, News News discussion forum and Wais database. Therefore, the Global Information Network can be said to be the largest electronic data world in the world today. The World Wide Web can already be regarded as a synonym for the Internet. In fact, what we usually call "on the Internet" actually refers to connecting to the World Wide Web. WWW is the abbreviation of World Wide Web (Global Information Network), which can also be referred to as Web. The Chinese name is "World Wide Web".

The reason why the Global Information Network is called the Information Network is entirely because its resources can be connected to each other. There are currently tens of thousands of Web sites in the world, and each Web site can be accessed through super Links (Hyper links) connect to other Web sites. Anyone can design their own Home Page, put it on a Web site, and then generate a link on your Home Page to connect to other people's Home Pages, or to Other Web sites; others can also connect to your Home Page or your Web site. The entire information network is woven together in this way, forming a huge global information network.
