Question

Consider a physical memory with 3-page frames; using each replacement policy, determine for which memory reference a page fault can happen. For LRU: Frame Reference 1 2 1 3 2 1 4 3 1 1 2 4 1 5 6 2 1 0 1 2 Fault? Y Y N Y N N Y Y N N Y Y Y Y Y Y The total number of faults is 11. For clock: Frame Reference 1 2 1 3 2 1 4 3 1 1 2 4 1 5 6 2 1 0 1 2 Fault? Y Y N Y N N Y N Y N Y Y N Y Y N Y The total number of faults is 9.
