Web 2.0 –
Web 2.0 refers to world wide website which highlight user-generated content, usability and interoperability for end users. It is also called participative social web. It does not refer to a modification to any technical specification, but to modify in the way Web pages are designed and used. The transition is beneficial but it does not seem that when the changes are occurred. An interaction and collaboration with each other is allowed by Web 2.0 in a social media dialogue as creator of user-generated content in a virtual community. Web 1.0 is enhanced version of Web 2.0.

Web 3.0 –

It refers the evolution of web utilization and interaction which includes altering the Web into a database. In enables the upgradation of back-end of the web, after a long time of focus on the front-end . Web 3.0 is a term which is used to describe many evolutions of web usage and interaction among several paths. In this, data isn’t owned but instead shared, where services show different views for the same web / the same data. The Semantic Web 3.0 promises to establish “the world’s information” in more reasonable way than Google can ever attain with their existing engine schema. This is particularly true from the perspective of machine conception as opposed to human understanding. The Semantic Web necessitates the use of a declarative ontological language like OWL to produce domain-specific ontologies that machines can use to reason about information and make new conclusions, not simply match keywords.

main features that can help us define Web 3.0:

• Semantic Web
  The succeeding evolution of the Web involves the Semantic Web. The semantic web improves web technologies in demand to create, share and connect content through search and analysis based on the capability to comprehend the meaning of words, rather than on keywords or numbers.
• Artificial Intelligence
  Combining this capability with natural language processing, in Web 3.0, computers can distinguish information like humans in order to provide faster and more relevant results. They become more intelligent to fulfil the requirements of users.
• 3D Graphics
  The three-dimensional design is being used widely in websites and services in Web 3.0. Museum guides, computer games, ecommerce, geospatial contexts, etc. are all examples that use 3D graphics.
• Connectivity
  With Web 3.0, information is more connected thanks to semantic metadata. As a result, the user experience evolves to another level of connectivity that leverages all the available information.
• Ubiquity
  Content is accessible by multiple applications, every device is connected to the web, the services can be used everywhere.
