1. consider a system where 3 page frames are allocated to a process. consider the following sequence of memory references: 3 2 1 0 3 2 4 3 2 1 0 4. assuming no pages are initially in memory, how many page faults are there assuming a fifo page replacement algorithm is used? 2. repeat problem 1 with number of frames increased to 4.3. compare the number of page faults from 1 and 2. is there belady’s anomaly? 4. repeat problems 1 and 2 using optimal page replacement algorithm.5. what is the difference between local and global page replacement?
