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?

Both M and N are true and N is the reason for M
Both M and N are true but N is not the reason for M
Both M and N are false
M is false, but N is true

Option 2 : 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?
