The simple answer: It's a marriage of two technologies (java script and XML) so the term Ajax was coined.
There are many, many tutorials out there. It depends on what you want to learn and how you prefer to learn.

My understanding is that it's called asynchronous because you aren't doing a full submit of the form. With standard forms, you'd submit the form which would contact the server, wait for an answer and spit back a response. This usually involved multiple pages or some carefully crafted code, error handling, etc.
With Ajax, everything is happening on the fly and in the background. The data is sent and retrieved, without leaving the page you're on or "waiting".
