ABSTRACT This paper named Paging and page fault handling mechanisms explains the paging activity in memory management. Memory management is the important function of operating system. All the processes must be resided in main memory at the time of execution. If the memory size is limited and the process size is high, some of the pages are kept in secondary memory and the pages needed to execute must bring to main memory before starting execution. When a page is needed and it is currently not in main memory, operating system brings the required page to main memory and a page already in memory is brought back to secondary memory. Various schemes are used for this page replacement operation. This paper explains the different page replacement schemes and their efficiency.
