What term describes a second generation of the web enabling better collaboration and information sharing?

The term that describes the second generation of the web, which significantly enhances collaboration and information sharing among users, is indeed Web 2.0. This phase of the web introduced greater interactivity and user-generated content, shifting the focus from static web pages to dynamic and user-centric platforms.

Web 2.0 encompasses various social media platforms, blogs, wikis, and collaborative tools that allow individuals to easily create, share, and interact with content. This increased level of participation is a hallmark characteristic of Web 2.0, making it distinct from its predecessor, Web 1.0, which was primarily about content consumption with limited user interaction.

The subsequent generations, known as Web 3.0 and Web 4.0, build on these concepts with further developments in semantic web technologies and even more advanced interactivity, but the specific focus on enhanced collaboration and information sharing is central to the definition of Web 2.0.
