Swap Space vs Backing Store
<p>I am currently reading about memory management in my operating systems textbook and am curious if there is a difference between a swap space and a backing store.  They both seem to do the same thing in general.  From what I understand when a page fault occurs an inactive page is found and stored in the swap space so the page that caused the fault can be stored.  A backing store seems to do the same thing except it's for an entire process not just a page.  Is this the main difference between the two? Or are there other things I am over looking?</p>
