What is Web 2.0?

Web 2.0 is not a new version of the World Wide Web, but rather a collection of new technologies that changes the way users interact with the Web. When Tim Berners-Lee (1955–) created the World Wide Web it was a repository of information with static content and users were generally unable to easily change or add to the content they were viewing. Newer technologies allow users to contribute to the Internet with blogs, wikis, and social networking sites.

A further distinction of Web 2.0 is “cloud computing” where data and applications (“apps”) are stored on Web servers, rather than on individual computers, allowing users to access their documents, files, and data from any computer with a Web browser. Apps include many products, such as word processing and spreadsheets, that were traditionally found in software packages.
