    Abstract

    If CPU try to refer a page that is currently not available in the main memory, it generates an interrupt indicating memory access fault. The OS puts the interrupted process in a blocking state. For the execution to proceed the OS must bring the required page into the memory. The OS will search for the required page in the logical address space. The required page will be brought from logical address spac

      1. If CPU try to refer a page that is currently not available in the main memory, it generates an interrupt indicating memory access fault.

      2. The OS puts the interrupted process in a blocking state. For the execution to proceed the OS must bring the required page into the memory.

      3. The OS will search for the required page in the logical address space.

      4. The required page will be brought from logical address space to physical address space. The page replacement algorithms are used for the decision making of replacing the page in physical address space.

      5. The page table will updated accordingly.

      6. The signal will be sent to the CPU to continue the program execution and it will place the process back into ready state.




    whenever a page fault occurs these steps are followed by the operating system and the required page is brought into memory.
