Web 2.0

Web 2.0 is the second generation of web-based communications and hosted services. Web 2.0 uses Ajax which stands for JavaScript & XML as a way to improve web pages for the World Wide Web. Web 2.0 allows large or small parts within a web page to update and use new information obtained over the network in response to user actions. The use of Web 2.0 allows the World Wide Web to use clean and meaningful URLs, look at open source software, use syndication and aggregation of data programs in RSS, and the ability to change Cascading Style Sheets.
