Q3. (a) Consider a demand-paging implementation with 3 frames, all initially empty. Demonstrate the sequence of page replacements that would occur for the reference sequence below for (i) First-In-First-Out (FIFO) and (ii) Least Recently Used (LRU) and (iii) Most Recently Used (MRU). For both cases, calculate the total number of page faults include every page fault). (3 pts each) Reference String: 0 325031032513 03 b) Explain how you could determine whether either of these algorithms suffers from Bldy's anomaly for this reference string. (3 pts) (c) In the reference string below, identify the optimal working set size for a A-10. (3 pts) 2615777751623412344434344413234443444
