    AJAX Technologies

    As describe earlier, ajax is not a technology but group of inter-related technologies. AJAX technologies includes:

    HTML/XHTML and CSS
    DOM
    XML or JSON
    XMLHttpRequest
    JavaScript
    HTML/XHTML and CSS

    These technologies are used for displaying content and style. It is mainly used for presentation.

    DOM

    It is used for dynamic display and interaction with data.

    XML or JSON

    For carrying data to and from server. JSON (Javascript Object Notation) is like XML but short and faster than XML.

    XMLHttpRequest

    For asynchronous communication between client and server. For more visit next page.

    JavaScript

    It is used to bring above technologies together.

    Independently, it is used mainly for client-side validation.
