What is Web 2.0 and web 3.0..?

I also don't know about web 3.0. I have tried to search on google but did not get valuable info. Please if anyone knows then share here.

Web 2.0 describes World Wide Web sites that emphasize user-generated content, usability, and interoperability. The term was popularized by Tim O'Reilly and Dale Dougherty at the O'Reilly Media Web 2.0 Conference in late 2004, though it was coined by Darcy DiNucci in 1999.

This definition of Web 3.0 is the popular view held by Tim O'Reilly. In contrast, Nova Spivack defines Web 3.0 as connective intelligence; connecting data, concepts, applications and ultimately people.

Web 2.0: there is no actual update or new technical modification. Web 2.0 also utilizes social networking tools to further increase the level of viewer participation.
Web 3.0: The Internet will be able to perform tasks faster and more efficiently, such as search engines being able to search for the actual individual users interests, and not just for the keyword typed into search engines. We are not there yet, but we will someday soon, and educators must be prepared because Web 3.0 technology will truly move the classroom beyond the basic lecture and take it to new exciting territories!
