Web 2.0

Web 2.0 enhances the information sharing, the creativity and the collaboration amongst its users. This term is used to describe the change in the trends, in the usage of World Wide Web technology. Though from the term you feel as if it is some new version of world wide web but that is not true, instead it refers to, how the software developers and the end users have changed the way to utilize the web. So with this change new hosted services (like blogs, social networking sites, folks monies & Wikis) and Web based communities have evolved and developed.

In Web2.0 interactive facilities from “web1.0” are built through which you can run the entire software-application with the help of a browser. Here the users are allowed to do much more than just retrieving information. They can own the data and have control over it. You can also add “Architecture of participation” to the site, which encourages the user to add to the application accordingly. The sites of Web2.0 feature user friendly interface, base on rich media.

Its few characteristics are: dynamic content, openness, collective intelligence, user participation web standards and scalability, freedom. Though people consider, AJAX is must for Web2.0 sites function, but that’s not true. With AJAX Web2.0 sites function well but it is not necessary for their function.

Another characteristic of Web 2.0 sites is its Fermium business model in which basic core services are given for free. Site content syndication may be regarded as a feature of Web2.0, which allows its end-users to use site data in some other context (like some another website, separate desktop application or a browsing plug).

Protocols which allow the syndication are RSS (Really Simple Syndication). Atom and RDF, these all are XML-format and they are referred as ‘web feed’. So if you want to know more and work on it then it is better to take help of some one professional.
