Web 2.0

Web 2.0 refers to the second generation of the World Wide Web, which enables interactive, user-centered, and collaborative online experiences. It marks the transition from static web pages to dynamic web applications that encourage user participation and interaction.

A central aspect of Web 2.0 is user participation. Platforms like social networks (Facebook, Twitter), blogs, and wikis allow users to create, share, and comment on content. This transformation has turned the internet from a purely consumption-oriented medium into a participatory platform.

Another important aspect is interactivity. Web 2.0 applications utilize technologies such as AJAX (Asynchronous JavaScript and XML) to create responsive and user-friendly interfaces. This allows for real-time updates and seamless user experiences without constant page reloads.

Example: Google Maps uses AJAX to update and move maps without needing to reload the entire page, providing a smoother user experience.

Social networking and social media are central elements of Web 2.0. These platforms promote networking and information exchange among users. They enable the formation of networks, the viral spread of content, and the creation of communities around shared interests.

In summary, Web 2.0 is an evolution of the internet characterized by interactive and collaborative technologies. It has revolutionized the way people use the internet and interact with each other, laying the foundation for many modern web applications and social media.
