A virtual memory system uses FIFO page replacement policy and allocates a fixed number of frames to the process. Consider the following statements M : Increasing the number of page frames allocated to a process sometimes increases the page fault rate N : Some programs do not exhibit locality of reference Which one of the following is true?

A virtual memory system uses FIFO page replacement policy and allocates a fixed number of frames to the process. Consider the following statements M : Increasing the number of page frames allocated to a process sometimes increases the page fault rate N : Some programs do not exhibit locality of reference Which one of the following is true? Correct Answer Both M and N are true but N is not the reason for M

Statement M: True

Increasing the number of page frames allocated to a process sometimes increases the page fault rate in the case of FIFO and Random page replacement algorithms, this is called Belady's anomaly.

Statement N: True

Also some programs do not exhibit locality of reference, but this is not the reason for first statement.

Consider a process executing on an operating system that uses demand paging. The average time for a memory access in the system is M units if the corresponding memory page is available in memory, and D units if the memory access causes a page fault. It has been experimental measured that the average time taken for a memory access in the process is X units. Which one of the following is the correct expression for the page fault rate experienced by the process?
Recall that Belady’s anomaly is that the page-fault rate may increase as the number of allocated frames increases.
