Page stealing

  • A.is a sign of an efficient system
  • B.is taking page frames from other working sets
  • C.should be the tuning goal
  • D.is taking larger disk spaces for pages paged out

Answer: B

Correct answer: is taking page frames from other working sets

Page stealing is the memory manager taking a frame away from one process’s working set to satisfy another’s page fault. It is a sign that memory is over-committed, not that the system is well tuned, and it leads to thrashing if it goes far enough.
