In operating system concepts, what does 'Belady’s Anomaly' describe?
A.A file allocation bug where small files corrupt the master partition table.
B.A phenomenon where allocating more physical memory frames results in an increase in the number of page faults for certain page reference strings under FIFO replacement.
C.A network protocol lockup scenario.
D.A process scheduling glitch where higher priority threads starve indefinitely.
Explanation:
Belady's Anomaly shows that for certain page reference streams under the First-In-First-Out (FIFO) replacement scheme, adding page frames increases page faults.
