Web 2.0 does not refer to any specific change in the technology of the Internet, but rather the behavior of how people use the Internet. It is the movement toward dynamic web pages, shareable content, social networking, and web applications that facilitate interactive information sharing, collaboration and creativity. It enables people with no specialized technical knowledge to create their own websites. It is the development and delivering of services tailored to the needs of each user. Advanced Internet technology and applications include:
Wiki: A piece of software that allows users to freely create and edit Web page content. A wiki is a website designed for multiple people to collaborate by adding and editing content. Wikis are not usually considered “authoritative” or “scholarly”because people can invent facts or pass off ideas as facts, they contain a lot of suspect information. These sites are still not considered reliable or trustworthy. If you find information on a wiki, you should verify that data by checking it against the information in another source, such as an encyclopedia, dictionary, or index.
Blog: A shared on-line journal where people can post diary entries about their personal experiences and hobbie. These blogs allows users to reflect, share opinions, and discuss various topics in the form of an online journal while readers may comment on. Most blogs have not been fact-checked and contain information that probably would not be considered “authoritative” by professors or scholars. However, blogs can be used to help determine the popular responses to current events or modern culture.
RSS: Really Simple Syndication is used to publish frequently updated works, such as blogs, news headlines, audio, and video in a standardized format.An RSS document is called a "feed", "web feed", or "channel". Web feeds benefit publishers by letting them syndicate content automatically. They benefit readers who want to subscribe to timely updates from favored websites or to aggregate feeds from many sites into one place. RSS feeds can be read using software called an "RSS reader", "feed reader", or "aggregator".
Social Bookmarking: Similar to web browser bookmarks, social bookmarking stores individual pages online and allows you to 'tag' them which allow internet users to share. Unlike file sharing, the resources themselves aren't shared, merely bookmarks that reference them.
