Web 2.0
Commonly used in General IT, Web Development
Web 2.0 refers to the second generation of the World Wide Web that emphasizes user participation, collaboration, and interactive web applications. Unlike earlier static web pages, Web 2.0 enables users to create, share, and modify content easily, transforming the web into a more dynamic and social platform.
How It Works
Web 2.0 is characterized by the shift from static HTML pages to more interactive and user-centric websites. This is achieved through technologies such as <a href="https://www.ituonline.com/it-glossary/?letter=A&pagenum=2#term-ajax-asynchronous-javascript-and-xml" class="itu-glossary-inline-link">AJAX (Asynchronous JavaScript and XML), which allow web pages to update content dynamically without reloading. Web 2.0 also relies heavily on social media platforms, blogs, wikis, and content sharing sites that facilitate user-generated content. These platforms often incorporate APIs (Application Programming Interfaces) to enable integration and collaboration across different services. The emphasis on collaboration and real-time communication has led to the development of social networking, tagging, and content rating systems, making the web more participatory.
