Ajax, or Asynchronous JavaScript and XML, is a term describing the latest rage in web development. Ajax is used to create interactive web applications with XML-based web services, and using JavaScript in the web browser to process the web server response. End users see a more responsive application on the web, often with client-like functionality. Ajax reduces the amount of data interchanged between the web browser and web server, which saves processing and speeds up the web experience.
