13 Page tables map virtual addresses as seen by the CPU into physical addresses
20 The physical address corresponding to the virtual address is often referenced
21 by the underlying physical page frame. The **page frame number** or **pfn**
22 is the physical address of the page (as seen on the external memory bus)
25 Physical memory address 0 will be *pfn 0* and the highest pfn will be

168 MMU uses the page walks to determine the physical address and create the map.
