The page size in the system is 4 KB A virtual address is a page number followed by a byte offset within the page. (a) How many bits of the virtual address must be used for the offset, so that every byte in the page can have a unique address? (b) How many bits are left over in the virtual address to store the page number? (c) How many different page numbers does an address space in this system support? (You can express this as a power of two) (d) If a page table consists of a page table entry for each page number in an address space, how much space in MB would the page table take up if it were stored in physical memory? 2 Given the assumptions above and the page table below, translate the following virtual addresses (expressed as base ten integers) to physical addresses (also base ten integers). If the corresponding page is not resident in memory (NR), indicate a page fault Hint: rather than translating these values to binary or hexadecimal, you can use the following formulas pageNum = |virtualAddress/pageSize] where [x] is x rounded down to the nearest integer offset virtualAddress mod pageSize where x mody is the remainder after dividing x by y physicalAddress frameNum x pageSize + offset.
