World Wide Web 1.0
According to Tim Berners Lee (TimBL) World Wide Web 1.0 is a only “read” only web. In other words, the early web allowed us to search for information and read it. There was very little in the way of user interaction or content generation. The flow of the information on the World Wide Web 1.0 is only a one way, there’s no interaction. You can’t comment or reply what your thoughts are.
World Wide Web 2.0
As Tim Berners Lee Described the World Wide web 2.0 is a “read and write” web. It’s the ability to contribute content and interact with other web users.
Web 2.0 is a welcome response to web users, who want to participate in the information. The flow of the information on the World Wide web 2.0 is a two-way it can interacts with the people who share and can leave a comment or reply what your thoughts are.

To illustrate, consider semantic markup and web services.
Semantic markup refers to the communication gap between humans and computerized applications. One of the biggest challenges of presenting information on the web is that applications cannot provide context to data, and, therefore, can’t understand what is relevant. Through the use of some sort of semantic markup (or data interchange formats), data could be put in a form not only accessible to humans via natural language, but able to be understood and interpreted by software applications as well.
A web service is a software that supports computer-to-computer interaction over the internet .
