The term "Web 2.0" describes the changing trends in the use of World Wide Web technology and web design that aim to enhance creativity, communications, secure information sharing, collaboration and functionality of the web.
Although the term implies a new version of the Web, it does not actually refer to an update to any technical specifications, but rather to cumulative changes in the ways software developers and end-users utilise the Web.
