Web 2.0 is a collective term for numerous technologies that enable the "second" generation of the internet. This second generation focuses on building communities of dedicated users, with the aim of collaboratively constructing and fostering knowledge centered around products, companies, systems of thought, hobbies, and other shared interests.
Web 2.0 communities thrive by leveraging collaborative applications and information-gathering tools such as wikis, blogs, forums, syndication, interactive voice messaging, and instant messaging. These applications are frequently built on emerging development standards and messaging exchange protocols, such as RSS (Really Simple Syndication), XML (Extensible Markup Language), AJAX (Asynchronous JavaScript and XML), and SIP (Session Initiation Protocol).
Web 2.0 communities and applications increasingly tend to generate large volumes of data, necessitating greater tolerance for the types of data that users can produce. This flexibility, however, can lead to increased vulnerabilities in web applications, growth in the volume of data transferred between users and applications, and a higher risk of data loss if issues arise.
