Belady anomaly is occur in case of-
1.LRU page replacement policy
2.FIFO page replacement policy
3.Optimal page replacement policy
4.All of the above
Consider a page string 1 2 3 4 1 2 5 1 2 3 4 5, and we have 3 number of frame available, and if we use FIFO policy for page replacement policy then the number of page fault occur is ?
1.10
2.12

When we increases the number of frame so instead of decreasing the page fault it can increases, this type of anomaly known as
1.Belady anomaly
2.Frand anomaly
3.greedy anomaly
4.None of the above
Which of the following page replacement policy guarantees minimal page fault ?
1.optimal
2.FIFO

Which of the page replacement policy are not to be implemented in practical situation ?
1.FIFO
2.LRU
3.Optimal
4.LIFO
While executing some processes,Page fault occur in FIFO, LRU and optimal are x,y and z respectively. which of the following are always considered as true ?
1.z is always greater or equal to the x
2.z is always greater or equal to the y
3.There is no relation between x and y
4.All of the above
