(b) Table 3 illustrates the frames used with the current page reference using LRU page replacement algorithms at time t10. Answer the following questions. Table 3 0 1 2 3 Frame Page Reference 2 1 3 4 i) Consider the following new page reference string: 21562 1 2 3 7 6 3 2 1 2 3 5 By constructing a table with the page reference in the frames, identify how many page faults would occur using the same page replacement algorithms? Show your working. [7 Marks] ii) Based on the previous answer, how to reduce the page fault number? Briefly, justify your answer. [3 Marks]
