Operating system offers a service known as memory management which manages and guides primary memory. It
moves processes between disk and main memory during the execution back and forth. The process in which we provisionally
moves process from primary memory to the hard disk so the memory is available for other processes. This process is known as
swapping. Page replacement techniques are the methods by which the operating system concludes which memory pages to be
swapped out and write to disk, whenever a page of main memory is required to be allocated. There are different policies
regarding how to select a page to be swapped out when a page fault occurs to create space for new page. These Policies are
called page replacement algorithms. In this paper the strategy for identifying the refresh rate for ‘Aging’ page replacement
algorithm is presented and evaluated.
