*A brief overview : ( from the net )* ** *Web1.0:* The information published on the web in a static manner. It is like your word document on the web with pictures and formatting done neatly. Hyper-linking the web-pages and bookmarking were two of the most important aspect of Web1.0 world. . *Web2.0: *This term was coined by Tim O’Reilly The information published in web2.0 world is very different from web1.0. There is a very high importance given on usability and sharing. The information published in Web2.0 world travels like wild fire, either partially or in full. Web2.0 world has less clutter coupled with easy retrieval of precise information and furthermore building upon that information and sharing it further. Widgets and Tagging are two important features of Web2.0. *Web3.0: *To be honest, there are varied perceptions of what Web3.0 is. It is purely a word coined as the next version of Web2.0. One basic thing that everyone accept is Web3.0 will be a maze / network of application working together homogeneously. The users can do anything and everything they want from a single source on the web. There is yet a lot of time for Web3.0 world to arrive. Corrections, contributions are welcome.
