World Wide Web | Part 1
World Wide Web
The World Wide Web, the literally “web (spider) World”, commonly called the Web, sometimes the Web or WWW is a hypertext system operating on public Internet that provides access with a browser, the pages being online sites. The image of the spider has hyperlinks that link web pages between them.
The Web is an Internet application. Other Internet applications are email, instant messaging, Usenet, etc. The Web was invented several years after the Internet, but it was he who made the mainstream media attention to the Internet. Since the Web is often confused with the Internet in particular, the word Web is often used in non-technical texts without clearly expressed that he indicates the Web or Internet.
Terms designating the World Wide Web
The World Wide Web is and has been designated by many names and abbreviations synonyms: WorldWideWeb, World Wide Web, World-Wide Web, Web, WWW, W3, World Wide Web, Web World Wide Web.
The name of the original project was WorldWideWeb. The words were quickly separated by World Wide Web to improve readability. The name World-Wide Web has also been used by the inventors of the Web, but the name now advocated by the World Wide Web Consortium separates the three words without a hyphen. While “global” can be written world-wide or worldwide in English, spelling World Wide Web and abbreviation Web are now well established.
By inventing the Web, Tim Berners-Lee had also thought of other names, such as Information Mesh (mesh information), Mine of Information and The Information Mine (the Mine Of Information, whose acronym is Tim).
The acronym WWW has been widely used to shorten World Wide Web before the Web abbreviation takes precedence. Pronunciation laborious (in French and English) WWW probably precipitated its decline. WWW is often pronounced three ‘W’ or triple “W”.
The letters www remain, however, widely used in web addresses and some other uses formal or technical, though it does respond to any technical constraint. WWW is sometimes abbreviated as W3, abbreviation found in the acronym W3C World Wide Web Consortium.
Web 2.0
The term “Web 2.0″ was used from 2004. Its use has been massive and acknowledged around 2007. In principle, the term designates a certain evolution of the use of Web sites has become more interactive. The term was quickly re-used for marketing purposes, so that some computer scientists come to see that this expression does not exist other than marketing.
Since then, the term has been declined, first by adding “2.0″ to any concept to mean “based on Web 2.0 (e.g., Marketing 2.0). Similarly, to describe the evolution of the Web, many version numbers have been proposed (refer to Web 1.0, by contrast, started the Web) – some attempt to establish a consistent terminology, others parody.
