Ajax runs in the "background", making a request in intervals and update the 
correct section of the page when there is something to update, a simple way to 
see this is to use something like firebug and see what connections are made 
after the page has been loaded.

Web sockets has been introduced with html 5 (and there are a few diffe3rent 
standards too), which allows the server to push content to the browser instead 
of using ajax which pulls information from the server.
