Q1 - What is AJAX?
A - Ajax stands for Asynchronous Javascript & XML. It is a web technology through which a postback from a client (browser) to the server goes partially, which means that instead of a complete postback, a partial postback is triggered by the Javascript XmlHttpRequest object. In such a scenario, web-application users won't be able to view the complete postback progress bar shown by the browser. In an AJAX environment, it is Javascript that starts the communication with the web server.
Ajax technology in a website may be implemented by using plain Javascript and XML. Code in such a scenario may tend to look little complex, for which the AJAX Framework in .NET can be embedded in ASP.NET web applications.
In addition to XML & Javascript, AJAX is also based on DOM - the Document Object Model technology of browsers through which objects of the browser can be accessed through the memory heap using their address.
JSON - Javascript Object Notation is also one of the formats used in AJAX, besides XML.
So basically, in an AJAX-based web application, the complete page does not need to reload, and only the objects in context of ajaxification are reloaded.
Ajax technology avoids the browser flickering.
Q2 - Can Ajax be implemented in browsers that do not support the XmlHttpRequest object?
A - Yes. This is possible using remote scripts.
Q3 - Can AJAX technology work on web servers other than IIS?
A - Yes, AJAX is a technology independent of web server the web application is hosted on. Ajax is a client (browser) technology.
Q4 - Which browsers support the XmlHttpRequest object?
A - Internet Explorer 5.0+, Safari 1.2, Mozilla 1.0/Firefox, Opera 8.0 +, Netscape 7
Q5 - How to we create an XmlHttpRequest object for Internet Explorer? How is this different for other browsers?
A - For Internet Explorer, an ActiveXObject is used for declaring an XmlHttpRequest object in Javascript.
//Code as below for IE:
xmlHttpObject = new ActiveXObject("Msxml2.XMLHTTP");
//For Other browsers, code as below:
xmlHttpObject = new XMLHttpRequest();
Note that XmlHttpObject used above is simply a variable that holds the XmlHttpRequest object for the respective browsers.
There is a very good book as I remember called Internview Questions from Shivprasad Koirala which has broad Range of questions & answers in it specially for interview
