1) Consider a paging system with the page table stored in memory. 75 percent of all page-table references are found in the TLBs. We assume that a memory reference takes 360ns and finding a page-table entry in the TLBs takes 40ns. What is the effective access time? Show both the formula and the final result.

2) A. How could segmentation be used to reduce the page table size?

B. How could multiple-level paging be used to reduce the page table size?
