Ajax (Asynchronous Java Script and XML) offers Web developers a means to create rich client-like applications on Web pages without resorting to huge amounts of code or forcing users to download plug-ins.
A method of building interactive browser-based applications that process user requests immediately.
Technique used to obtain data from a server from a specific section of a web page.
Ajax, shorthand for Asynchronous Java Script and XML, 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.
