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.

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?
