AJAX-XMLHttpRequest Part1

I'm totally new to AJAX technology.Since I got an AJAX related task on my job,I had to carry out a research on it and get a clear understanding on it.Following is the knowledge I gained from that research.

Before talking about XMLHttpRequest, I'll describe what is AJAX.
Ajax (Asynchronous Javascript And XML) is a technique to submit server requests and return information from the server to the user without the necessity of waiting for a page load.

An Ajax script makes a request of a server by using the Javascript XMLHTTPRequest object,instead of using a a normal HTTP POST or GET request.XMLHTTPRequest retrieves information from the server in an invisible manner without using a page refresh.
