Suppose that there is a machine with $32-$bit addresses and a two$-$level page table. Note that the first $10$ bits of an address is an index into the first level page table and the next $10$ bits are an index into a second level page table. The page tables are stored in memory and each entry in the page tables is $4$ bytes. Suppose the space allocated to a specific process is $64$ Mbytes. How many pages are occupied by this process? How much space is occupied in memory by the page tables for the specific process?
