Memory and Page directories Question: Please Answer A and B and explain your answers. Thank you

4. Recall that in 32-bit x86, page directories and page tables are each made up of 1024 32-bit entries. Suppose we have 4 processes on a system, each of which has every possible virtual address mapped. (a) (5 points) How much memory is used to store the page directories and page tables if 4KB pages are used? (b) (5 points) If 4MB pages (super pages) are used, then the entries in the page direc- tory point directly to the page frame (i.e., no second-level page tables are used). How much memory would be taken up by page directories in this case? 4. Recall that in 32-bit x86, page directories and page tables are each made up of 1024 32-bit entries.
