What technology revolutionized the web with improved user interaction and content sharing?

The correct choice highlights the transition to a more interactive and participatory web experience that defines Web 2.0. This era marked a significant shift from the static pages of Web 1.0 to a dynamic user-centric web environment where users are both consumers and contributors of content. Technologies and platforms such as blogs, social media, and wikis emerged, allowing individuals to share their opinions, collaborate, and interact in real time.

Web 2.0 enabled robust user-generated content, facilitated community-driven services, and fostered social networking, which became the backbone of online interaction—characterized by engagement rather than mere information consumption. This era improved user interfaces, allowing for more intuitive navigation and more meaningful interactions with web applications.

In contrast, Web 1.0 is largely about delivering static content, primarily with limited user interactions. Web 3.0, often associated with concepts like semantic web and artificial intelligence, is focused on data connectivity and machine understanding, and Web 4.0 is still an emerging concept that may encompass advanced AI and the Internet of Things.
