| Abstract | ||
| Historically, main storage has been viewed as an expensive resource. As such, it has demanded the attention of systems designers. Regardless of what storage organization scheme we adopt for a particular system, we must decide what strategies cause to obtain optional performance. Paging works best if there always plenty of free pages frame that can be claimed as page faults occur. Page replacement is a basic to demand paging; it completes the separation between logical memory and physical memory. FIFO page replacement algorithm caused strange situation known "Belady's Anomaly". This paper will focus on this situation in details and determine in practical examples the case, and other anomalies cases which occur. By implementing special program we get tremendous results about the form and situation, which cause these cases. | ||
