Two different things:

$.ajax is a prototyped function of jQuery called ajax.

While $('foo') is a call of the jQuery function and depending on the type of foo it reacts in different ways. At http://api.jquery.com/jQuery you can see that jQuery (almost the same as $) can react on three different types: selectors, html or callbacks.
