Web 2.0 refers to the second generation of the World Wide Web that emphasizes user-generated content, usability, and interoperability. Unlike its predecessor, Web 1.0, which was primarily static and read-only, Web 2.0 enables users to interact, collaborate, and create content dynamically across various platforms. This evolution marked the rise of social media, blogs, wikis, video-sharing sites, and cloud-based applications. Web 2.0 encourages participation, making the internet more social and user-focused.
With technologies like AJAX, JavaScript, and APIs, websites became more responsive and interactive, allowing for real-time communication and seamless user experiences. Major platforms such as Facebook, YouTube, Twitter, and Wikipedia are classic examples of Web 2.0 in action, offering services where users contribute and consume content simultaneously.
