Web 2.0 is a living term describing changing trends in the use of World Wide Web technology and web design that aims to enhance creativity, information sharing, collaboration and functionality of the web. Web 2.0 concepts have led to the development and evolution of web-based communities and hosted services, such as social-networking sites, video sharing sites, wikis, blogs, and folksonomies. The term became notable after the first O'Reilly Media Web 2.0 conference in 2004. Although the term suggests a new version of the World Wide Web, it does not refer to an update to any technical specifications, but to changes in the ways software developers and end-users utilize the Web.
Web 2.0 has numerous definitions. Basically, the term encapsulates the idea of the proliferation of interconnectivity and interactivity of web-delivered content. Tim O'Reilly regards Web 2.0 as business embracing the web as a platform and using its strengths, for example global audiences. O'Reilly considers that Eric Schmidt's abridged slogan, fight the Internet, encompasses the essence of Web 2.0 as building applications and services around the unique features of the Internet, as opposed to expecting the Internet to suit as a platform (effectively "fighting the Internet").
Web 2.0 does not represent a new version of the World Wide Web at all, but merely continues to use so-called Web 1.0 technologies and concepts. Techniques such as AJAX do not replace underlying protocols like HTTP, but add an additional layer of abstraction on top of them...
Sponsored Link:Many of the ideas of Web 2.0 had already been featured in implementations on networked systems well before the term "Web 2.0" emerged. Amazon.com, for instance, has allowed users to write reviews and consumer guides since its launch in 1995, in a form of self-publishing. Amazon also opened its API to outside developers in 2002.
Sponsored Link:"Web 2.0" is a piece of jargon. Nobody really knows what it means. Many of the technology components of "Web 2.0" have existed since the early days of the Web.
Sponsored Link:Web 2.0 is not the first example of communication creating a false, hyper-inflated sense of the value of technology and its impact on culture. The dot com boom and subsequent bust in 2000 was a culmination of rhetoric of the technological sublime in terms that would later make their way into Web 2.0 jargon.
Sponsored Link:The extra functionality provided by Web 2.0 depends on the ability of users to work with the data stored on servers. This can come about through forms in an HTML page, through a scripting-language such as Javascript/Ajax, or through Flash, Curl Applets or Java Applets. These methods all make use of the client computer to reduce server workloads and to increase the responsiveness of the application.
Sponsored Link:Functionally, Web 2.0 applications build on the existing Web server architecture, but rely much more heavily on back-end software. Syndication differs only nominally from the methods of publishing using dynamic content management, but web services typically require much more robust database and workflow support, and become very similar to the traditional intranet functionality of an application server.
