Q. Under what conditions do page faults occur? Explain the actions taken by the operating system when a page fault occurs.
Answer: A page fault take places when an access to a page that has not been brought into main memory takes place. The operating system authenticates the memory access aborting the program if it is invalid. If it is valid a free frame is located as well as I/O is requested to read the needed page into the free frame. Upon completion of I/O the process table as well as page table are updated and the instruction is restarted.
Assume there are only 4 page frames in the physical memory, for the following reference string: 1, 2, 3, 4, 5, 3, 4, 1, 6, 7, 8, 7, 8, 9, 7, 8, 9, 5, 4, 5, 4, 2, 8. a) What i

Safety algorithm : This is to make sure if the system is in safe state or not. It may need an order of m x n2 operation to determine if the state of the system is safe or not.

Suppose a logical address space is 1KB, and the page-size is 16 bytes. Assume no page is in the main memory for this process initially and the pure demand paging is used. Current f
