Web 3.0, also known as the Semantic Web, is a vision for the future of the World Wide Web that emphasizes the ability of computers to understand the meaning of web content. In contrast to previous versions of the web, which were mainly designed for humans to read and interact with, Web 3.0 is intended to enable computers to understand and process web content in a more intelligent and sophisticated manner.

One of the key features of Web 3.0 is the use of semantic technologies, such as ontologies and metadata, to describe and represent web content in a way that is understandable by computers. This allows computers to process and understand web content in a more meaningful way, and to provide more advanced and intelligent services to users.

Web 3.0 is also characterized by the integration of web-based applications and services with the physical world, through technologies such as the Internet of Things (IoT) and augmented reality (AR). This allows web-based services to be linked with and connected to the real world, enabling new and innovative applications and services.

Overall, Web 3.0 is a vision for the future of the web that emphasizes the ability of computers to understand and process web content in a more intelligent and sophisticated manner. It is expected to enable new and innovative applications and services that will transform the way we use the web.
