A virtual memory system uses First In First Out (FIFO) page replacement policy and allocates a fixed number of frames to a process. Consider the following statements:
P : Increasing the number of page frames allocated to a process sometimes increases the page fault rate.
Q : Some program do not exhibit locality of reference.Which one of the following is TRUE?
  • a)
    Both P and Q are true, and Q is the reason for P
  • b)
    Both P and Q are true, Q is not the reason for P
  • c)
    P is false, but Q is true
  • d)
    Both P and Q are false
Correct answer is option 'B'. Can you explain this answer?
Verified Answer
A virtual memory system uses First In First Out (FIFO) page replacemen...
  • FIFO suffers from BELADY’s anomaly, in which sometimes page faults increase with increase in page frames. Hence, true.
  • Locality of reference depends on demand of process to access consecutive data and hence locality of reference may not always be satisfied. Hence, true
