No difference, except for the way that they're presented. A modal view controller is any view controller that's presented modally, using -[UIViewController presentModalViewController:animated:].

A modal view controller is used (usually) to gather information from the user before resuming operation. Basically, the view shown is only dismissed when the user completes a form or something similar. While shown, the modal view does not allow in any way accessing the other views shown, until it's dismissed.
