Web 2.0 represents a shift from static web pages to a more dynamic internet where users can interact and collaborate with each other online. Key aspects of Web 2.0 include social networking sites, wikis, cloud computing which allows access to files and programs from any device, and new technologies like smartphones that facilitate mobile internet use. To take advantage of Web 2.0, one must embrace its interactive and collaborative nature rather than treating the internet as a collection of isolated information silos.
