World Wide Web
The World Wide Web is the combination of 4 basic ideas:Hypertext: a format of information which allows one, in a computer environment, to move from one part of a document to another or from one document to another through internal connections among these documents (called "hyperlinks");Resource Identifiers: unique identifiers used to locate a particular resource (computer file, document or other resource) on the network;The Client-server model of computing: a system in which client software or a client computer makes requests of server software or a server computer that provides the client with resources or services, such as data or files; andMarkup language: characters or codes embedded in text which indicate structure, semantic meaning, or advice on presentation.On the World Wide Web, a client program called a web browser retrieves information resources, such as web pages and other computer files, from web servers using their URLs and displays them, typically on a computer monitor. One can then follow hyperlinks in each page to other resources on the World Wide Web whose location is provided by these hyperlinks. It is also possible, for example by filling in and submitting web forms, to post information back to a web server for it to save or process in some way. The act of following hyperlinks is often called "browsing" or "surfing" the Web. Web pages are often arranged in collections of related material called "websites."The phrase "surfing the Internet" was first popularized in print by Jean Armour Polly, a librarian, in an article called Surfing the INTERNET, published in the University of Minnesota Wilson Library Bulletin in June, 1992. Although Polly may have developed the phrase independently, slightly earlier uses of similar terms have been found on the Usenet from 1991 and 1992, and some recollections claim it was also used verbally in the hacker community for a couple years before that. Polly is famous as "NetMom" in the history of the Internet.For more information on the distinction between the World Wide Web and the Internet itself — as in everyday use the two are sometimes confused — see Dark internet where this is discussed in more detail.Although the English word worldwide is normally written as one word (without a space or hyphen), the proper name World Wide Web and abbreviation WWW are now well-established even in formal English. The earliest references to the Web called it the WorldWideWeb (an example of computer programmers' fondness for CamelCase) or the World-Wide Web (with a hyphen, this version of the name is the closest to normal English usage).Ironically, the abbreviation "WWW" is somewhat impractical as it contains two or three times as many syllables (depending on accent) as the full term "World Wide Web", and thus takes longer to say.
