Q. 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?
