We have a process that has been allocated 3 page frames and initially none of the pages of the process are available in the memory. The following sequence of page references (reference string) is made by the process : 1, 2, 1, 3, 7, 4, 5, 6, 3, 1If Optimal Page Replacement policy is used,_______ page faults will occur for the above reference string.

The following sequence of page references (reference string) is made by the process : 1, 2, 1, 3, 7, 4, 5, 6, 3, 1How many page faults will occur for the above reference string with the Least Recently Used(LRU) Page Replacement Policy in comparison to an Optimal Page Replacement policy?
Consider a virtual memory system that uses First In First Out (FIFO) page replacement policy and it allocates a fixed number of frames to a process. Consider the following two statements,1: Sometimes the page fault rate is increased if the number of page frames allocated is increased.2: Some programs do not exhibit Locality of reference.Which of the following is true?

Let P1 and P2 be the two processes and S1 and S2 be the two shared Boolean variables. The initial values of S1 and S2 are randomly assigned.
