Web 1.0, also known as the "static web," was the first generation of the World Wide Web and was characterized by a one-way flow of information. It was primarily used for viewing and accessing information, rather than for interaction and communication. Web 1.0 was mainly made up of static HTML pages that were difficult to update and lacked interactivity.

Web 2.0, also known as the "interactive web," marked the shift from a static to a more dynamic and interactive web. It introduced new technologies such as blogs, social media, and wikis, which allowed users to not only access information but also contribute and share it. Web 2.0 also introduced the concept of "Web 2.0 applications," which are web-based applications that allow users to collaborate and share data in real-time.

Web 3.0, also known as the "semantic web," is the next generation of the World Wide Web and is characterized by the use of artificial intelligence and machine learning to make the web more intelligent and intuitive. It aims to create a web that can understand and interpret the meaning of information, rather than just displaying it. Web 3.0 will allow machines to understand the context and meaning of information, enabling them to understand and interpret it in a more accurate and useful way.

In summary, Web 1.0 was a static web that mainly allowed users to view and access information, while Web 2.0 introduced interactivity and the ability for users to contribute and share information. Web 3.0 aims to make the web more intelligent and intuitive through the use of artificial intelligence and machine learning.
