Question

There is a set of page replacement algorithms that can never exhibit Belady's Anomaly, called :

a) queue algorithms
b) stack algorithms
c) string algorithms
d) None of the mentioned

Answer 1

The correct answer is d) None of the mentioned. Belady's Anomaly can be avoided by using Optimal page replacement algorithms such as Least Recently Used (LRU).

Step-by-step explanation:

The correct answer is d) None of the mentioned.

Belady's Anomaly is a phenomenon observed in the page replacement algorithms, where increasing the number of page frames can lead to an increase in the number of page faults. However, there are certain page replacement algorithms that do not exhibit Belady's Anomaly. These algorithms are known as Optimal page replacement algorithms.

One example of an Optimal page replacement algorithm is the Least Recently Used (LRU) algorithm, which replaces the page that has not been accessed for the longest time.
