From: "Dave Ings" 

There's a decent overview on Wikipedia ...

http://en.wikipedia.org/wiki/Ajax_(programming)

... but yes it's essentially an enhancement of the JavaScript execution environment.

The "secret sauce" that made it different from what came before
was the addition of the "XMLHttpRequest object" which facilitated
the dynamic updates that make Web applications like Google Maps so
interesting.
