8, (18%) Consider the following page reference string that references pages 0 to 4 ference number | 1. I 2. | 3. | 4. | 5. I 6. | 7. | 8. Page reference string 01231410 Read or write access | W | R | R | R ? W ? W R I R Using the page replacement policies below, which pages are stored in the frames after each access if a virtual memory system has 3 frames that are initially empty? How many page faults occur for each of the page replacement policies? (a) Least-Recently-Used (LRU) (b) Second-Chance using Clock implementation, (c) Enhanced Second Chance/Not-Recently-Used (NRU) A periodic reset of the "referenced" bit of all page table entries takes place just before the 4th and the 7th reference. (R,M) classification order is: (0,0), (0,1), (1,0), (1,1) Use the tables and boxes below to fill in your solution a) Least-Recently-Used umber | 1. | 2. | 3. | 4 . | 5. | 6. | 7. | 8 Page reference string01231410 Read or write access W RR R W WRR Reference n Frame 1 Frame 2 Frame 3 Number of page faults- (b) Second-Chance using Clock implementation Reference number 1.2.3. 4. 5.6. 7.8 Page reference string01 231410 Read or write access | w R | R | R | W W R Frame 1 Frame 2 Frame 3 Number of page faults (c) Enhanced Second Chance/Not-Recently-Used: Reference number | 1. | 2. | 3. | 4. | 5. | 6. | 7. | 8.
