Determine the number of page faults when references to pages occur in the following order : 1, 2, 4, 5, 2, 1, 2, 4. Assume that the main memory can accommodate 3 pages and the main memory already has the pages 1 and 2, with page one having brought earlier than page 2. (LRU page replacement algorithm is used) 
Consider the following page reference string: 1, 2, 3, 2, 4, 1, 3, 2, 4, 1 Assume that there are three-page frames which are initially empty. Let LRU, FIFO, OPTIMAL denote the number of page faults under the corresponding page replacement strategy. Then, which of the following is TRUE?
Recall that Belady’s anomaly is that the page-fault rate may increase as the number of allocated frames increases. Now, consider the following statements: S1: Random page replacement algorithm (where a page chosen at random is replaced) Suffers from Belady’s anomaly S2: LRU page replacement algorithm suffers from Belady’s anomaly Which of the following is CORRECT?
