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. 2. 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. %3D • offset = virtualAddress mod pageSize where x mod y is the remainder after dividing x by y. • physicalAddress = frameNum x pageSize + offset.

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.
2.
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.
off set = virtualAddress mod pageSize where x mod y is the remainder after
dividing x by y.
• physicalAddress = frameNum x pageSize + offset.
