NPS vs NAP vs NPAS....what are the differences in these components

Question

_{Saturday, January 16, 2010 2:40 PM}

Hi folks.  Studying for my 70-646 test which is next week.  I'm really getting confused on these three acronyms and what the different components are used for.  At times I feel like they refer to the same thing and others I feel that they are different.  If someone could give a brief explanation of these three items and how they work (or don't) work together I'd really appreciate it.  thanks.
