  1. asp stands for active server pages. it fors websites w/ login, message boards, chat rooms, or stories that have to react off of a database. if u look at the extensions of most websites its asp

  2. First of all, this isn’t limited to ASP.NET. It can be for PHP, JSP, etc.
    Ajax, Asynchronous Javascript And XML, is a technique in which you can call a server-side script, from the client-side (javascript) and have data/text/information returned to you. It can be returned in Text, JSON, XML. Then, again on the client-side using javascript, you can dynamically add/update information based on your return data. This prevents having to refresh/reload an entire page, only what is necessary.
    As for XML, it is just a standard in which to transmit information.
    See the source lists, for more information.

  3. Its actually pretty simple. Ajax allows your web applications to change small sections of a page without reloading the entire page. This allows pages to load faster (after the first load), and make a web application feel like a computer application.
    The XML part of Ajax is just a way to carry the data from whatever back end system you are using (doesn’t have to be ASP; I do most of my work in PHP) to the front end (Javascript). For really simple apps (changing the content of a page based on a link click for example) it is just as easy to send back the raw HTML to the Ajax script as it is to send XML.
