4. Consider the following reference string, for four (04) page frames: 1,2,3,4,5,3,4,1,6,7,8,7,8,9,7,8,9,5,4,5,4,2 Apply the Page Replacement Algorithms and Calculate total number of page-fsults if we tse the following algorithms? i. First IN First Out (FIFO) Page Replacement Algorithm. ii. Least-Recently Used (L.RU) Algorithm iii. Optimal Page Replacement Algorithm Which Algorithm gives the lowest page fault rate? (Show step-by-step process). [2.0 Marks] Ariswer : i. First IN First Out (FIFO) Page Replacement Algorithm Page Faults Occurred ii. Least-Recently Used (LRU) Algorithm Page Faults Occurred iii. Optimal Page Replacement Algorithm Page Faults Occurred 3 of 4 Minimum Page Fault Rate for Algorithm
