These are disadvantages of FIFO page replacement algorithm.

  1. The process effectiveness is low.
  2. When we increase the number of frames while using FIFO, we are giving more memory to processes. So, page fault should decrease, but here the page faults are increasing. This problem is called as Beladys Anomaly.
  3. Every frame needs to be taken account off.

Is it possible to overcome the disadvantages of first-in-first-out page replacement algorithm?

If possible then how to overcome that?
