Web 2.0 Definition Start

Web 2.0 is not a new version of World Wide Web, but its a different way to utilize Internet into web platform like weblogs, social book marking, wikis, podcasts, RSS feeds (and other forms of many-to-many publishing), social networking web, Web APIs, Web standards and online service provider. It is like open sourcing and genuine interactivity in which user can upload anything, download anything and can use the content according to its own wish. There is no restriction of more or less measure of content, uploading and downloading. All these are absolutely free.

According to OReilly, the inventor of Web 2.0, Web 2.0 is the business revolution in the computer industry caused by the move to the Internet as platform, and an attempt to understand the rules for success on that new platform. So Web 2.0 is a new way of business via Internet. It’s really a new business tactic that is being used on the mass level across the world. The success of YouTube, Orkut, MySpace, Flickr, Google, facebook, Wikipedia and many more websites are the biggest examples of Web 2.0.

Web 2.0 tools include Weblogging, Wikis, Social networking, Podcasts, Feeds, Social bookmarking, and Cascading Style Sheet.
Technical Overview
Web 2.0 has a complex and growing technology that includes server-software, content-syndication, messaging- protocols, standards-based browsers with plug-ins and extensions, and various client-applications. All these differ in functions and approaches but provide all the requirements beyond the expectation such as information- storage, creation, and dissemination capabilities.
A Web 2.0 website may usually feature a number of following techniques:
Rich Internet Application (RIA) techniques, optionally Ajax based
Cascading Style Sheet, CSS
Semantically valid XHTML markup and the use of Micro formats
Organization and collection of data in RSS Feeds/ Atom
Tags usage. Links to bookmarking or tagging sites.
Use of Wiki software either completely or partially
Blog publishing / Editing / Tagging
Mashups (A mix up of content and Audio using various script technologies)
REST or XML Webservice APIs.
Rendering of Downloadable content/ Viewable content in various formats (like scribd allows download of documents as PDF, TXT, DOC, XLS, PPT formats)
Optional – Podcasts
