This means that it would execute immediately and any variables
contained within the function won't be seen by other scripts.

jQuery is the jQuery object and is passed on as the parameter (the $
at the start).
A (hopefully) simpler example:
(function(parameter1, parameter2) {
var space = " ";
alert(parameter1 + space + parameter2); // alerts 'hello world'
})("hello", "world");
alert(space); // space is not defined
