1. Consider a 32bit address space with 2K bytes page size, assuming that each entry consists of 4 bytes, how much memory are required for the page table for each process? Explain your reason. 2. Evaluate FIFO, LRU and Second Chance page replacement algorithm by running it on the memory reference string below and completing the tables provided. Compare the number of page faults resulted. Reference string: 6, 3, 5, 4, 4, 3, 2, 2, 4, 6, 2, 3 FIFO Page Faults: LRU 6 3 5 4 4 3 2 2 4 6 2 3 Second Chance 635 4 4 3 Page Faults: 224 6 3 5 4 4 3 2 2 4 Page Faults: 6 2 3 6 23
