WebOccasionally, an exception, i.e., increased frames, leads to more page faults. Belady's anomaly refers to this exception. This issue is caused by the page replacement algorithm that governs demand paging. Here are a few page replacement algorithms in which Belady's Anomaly most frequently occurs: First In First Out (FIFO) Second Chance Algorithm Web30 Apr 2024 · Here, the second chance is based on the fact that if the element is seen “recently” its reference bit (bitref) is set to 1 (true). If it was not seen recently, we would not have set its reference bit (bitref) to 1 (true) and thus removed it. Hence, this is why, it is an …
