 ## Paging
 _Paging_ is a memory management scheme that separates virtual and physical memory. The address space is split into equal sized _pages_ and _page tables_ specify which virtual page points to which physical frame. For an extensive paging introduction take a look at the paging chapter ([PDF][paging chapter]) of the [Three Easy Pieces] OS book.
