Answer:
Web 1.0 sites are static. They contain information that might be useful, but there's no reason for a visitor to return to the site later. An example might be a personal Web page that gives information about the site's owner, but never changes. A Web 2.0 version might be a blog or MySpace account that owners can frequently update.
Web 1.0 sites aren't interactive. Visitors can only visit these sites; they can't impact or contribute to the sites. Most organizations have profile pages that visitors can look at but not impact or alter, whereas a wiki allows anyone to visit and make changes.
Web 1.0 applications are proprietary. Under the Web 1.0 philosophy, companies develop software applications that users can download, but they can't see how the application works or change it. A Web 2.0 application is an open source program,which means the source code for the program is freely available. Users can see how the application works and make modifications or even build new applications based on earlier programs. For example, Netscape Navigator was a proprietary Web browser of the Web 1.0 era. Firefox follows the Web 2.0 philosophy and provides developers with all the tools they need to create new Firefox applications.
