Is it necessary to bind the event? What does that actually do in plain english?

I practiced without using this: 

  //Bind change listener to the select
  $select.change(function(){
    //Go to select's location
    window.location = $select.val();
  });

and it worked. So I am not sure why the bind is necessary. Can you explain "binding" and then "unbinding"? Can you also provide a real world example where you would "bind" and then "unbind"?

Thanks!

Binding to an event means to attach a piece of functionality to an event. If you don't bind, nothing will happen.

A scenario where you may want to "unbind" or stop listening for an event would be if you didn't want something to be editable anymore.

Thanks, Andrew. I think I got confused because I've seen the word "bind" as part of a function. Maybe I mis-remembered ...
