Answer / guest
It is also called FIFO anomaly. Usually, on increasing the
number of frames allocated to a process' virtual memory,
the process execution is faster, because fewer page faults
occur. Sometimes, the reverse happens, i.e., the execution
time increases even when more frames are allocated to the
process. This is Belady's Anomaly. This is true for certain
page reference patterns

Answer / manish mishra
Belady's anomaly is in context with the page faults occurring in FIFO page replacement policy. It says that on increasing the number of page frames, the no. of page faults do not necessarily decrease, they may also increase. LRU page replacement algorithm is free from Belady's anomaly.

Answer / app
when the no of frames increases , page fault increases

Answer / shiv ram
If by increasing number of block,the performance of algorithm decreases then this unexpected result is called beladys anomaly.

Answer / meghana n
as the no of page frames increases so as the page fault increases,it can be seen only in FIFO page replacement method.this is called belady's anamoly principle

Answer / anjali
IN FIFO IF FRMAE IS INCREASES THEN NUMBER OF PAGE FAULT
MIGHT DECREASES THIS IS CALLED BELADY ANOMALY. THIS IS ONLY
A RESULT OF FIFO, BELADY ANOMALY OCCURS DUE TO REFERENCE OF
LOCALITY.
