Which of the following page replacement algorithm suffers from Belady anomaly?
FIFO page replacement algorithm suffers from Belady anamoly.
Belady's anomaly proves that it is possible to have more page faults when increasing the number of page frames while using the first in first out (FIFO) page replacement algorithm.
In computer storage, Belady’s anomaly is the phenomenon in which increasing the number of page frames results in an increase in the number of page faults for certain memory access patterns. This phenomenon is commonly experienced when using the first-in first-out (FIFO) page replacement algorithm. In FIFO, the page fault may or may not increase as the page frames increase, but in Optimal and stack-based algorithms like LRU, as the page frames increase the page fault decreases.
