A system implements a paged virtual address space for each process using a one-level page table. The maximum size of virtual address space is 8MB. The page table for the running process includes the following valid entries (the -> notation indicates that a virtual page maps to the givenpage frame, that is, it is located in that frame): Virtual page 2 -> Page frame4 Virtual page 4 -> Page frame 9 Virtual page 1 -> Page frame2 Virtual page 3...
