4. Discuss situations in which the least frequently used (LFU) page-replacement algorithm generates fewer page faults than the least recently used (LRU) page-replacement algorithm. Also discuss under what circumstances the opposite holds. Answer Consider the following sequence of memory accesses in a system that can hold four pages in accessed, the least frequently used page-replacement algorithm would replace a page other than 1, and therefore would not incur a page fault when 3452" the least recently used algorithm performs better. memory: 1123 451. When page 5 is page 1 l is accessed again. On the other hand, for the sequence "12 Strin reference723 LRu Repalement LFU Replace ent 17 2 35 1 72 35 5 2 Page faults Page fouts = 5 Freauencies 1-2 7-0 21-1 51 String veterence: 12945 2 LRu LFu Repacement I 234 52 2. e fault 5 uencies 1-0, 2-2 3 4 Step by Step Solution
