9.(12 marks) Suppose that in a computer system, Virtual Memory and the Page-Fault Frequency Scheme are used. In addition, disk blocks have the same size as frames in physical memory Assume further that in the same computer system: The total size of the physical memory is 268,435,456 bytes. The smallest addressable memory unit is one (1) byte. The system has a 32-bit logical address space, containing 1,048,576 pages. Each process' logical address space is represented as a continuous array of bytes holding either code or data. The amount of memory space wasted due to internal fragmentation is 524,160 bytes. - Each secondary storage access (disk access) takes at most 30 milliseconds. Calculate as accurately as possible the maximum amount of time that it would take for the operating system to suspend a process and allocate its frames to other processes when the actual page-fault rate exceeds the acceptable" page-fault rate?
