A certain computer provides its users with a virtual address space of 2^32 bytes. The computer has 2^22 bytes of physical memory.

(1) How many physical page frames does this computer have in physical memory?

The virtual memory is implemented by paging with virtual addresses formatted as follows: the left 12 bits are used for the Virtual Page Number and the right 20 bits are used for the OFFSET.

(2) How many virtual pages can a virtual address space in this system have? How large is each page (express your answer in kB, MB, or GB, whichever is most appropriate)?

The system doesnt use TLB. A user process generates the virtual address 0x0012D687.

(3) Write a detailed explanation for how the system establishes the corresponding physical location.
