What is the difference between Web 1.0 And Web 2.0?

  The difference between Web 1.0 and Web 2.0 is that with Web 2.0 you use the Internet and communicate through it. The Web 1.0 was very straight. The Internet was seen for business. Webmaster's created websites and users visited and just viewed them. Communication was between Webmaster and client only. Webpages were static, when you needed any information the only thing you could do was to “Ask Jeeves” or “Yahoo”, now we can  “Google it”, “Bing it” or ask questions of other users in forums. 

Web 2.0 sites allow users to interact with the site and Webmaster but also with other people who also access the site. Web 2.0 is about web applications that users can interact with and control. Nowadays anyone and everyone is creating their own webpages filled with content that they enjoy. Making webpages is now within the reach of people who have no programming knowledge. In Web 1.0 website creation was left to the “experts” to do. The use of the Internet went from being controlled by expert web masters to being driven by users. Users are now involved in creating their own Internet experience.
