Web 2.0 Trends

Ajax is a shorthand for Asynchronous JavaScript and XML.


It is a web development technique for creating interactive web applications. The intent is to make web pages feel more responsive by exchanging small amounts of data with the server behind the scenes, so that the entire web page does not have to be reloaded each time the user requests a change. This is meant to increase the web page's interactivity, speed, and usability.

Concept

The browser (or client) will load a web page from a web server, and the web page contains Javascript which will be interpreted by the Ajax engine with in the browser.

Web 2.0 is actually a phrase coined by O'Reilly Media in 2004. As most other definitions, Web 2.0 doesn't have a hard boundary

On September 30, 2005, Tim O'Reilly wrote a piece summarizing the subject. The mind-map pictured above (constructed by Markus Angermeier on November 11, 2005) sums up the memes of Web 2.0, with example-sites and services attached (See the above picture).
