Q3. (3 points) A paging system is experiencing a page fault rate of 2 in 1 million page references, when a p frame replacement is needed. Assume that it takes 10 miliseconds to service a page fault needing no frame replacement, when frame replacement is needed, 40% of time the frame has been modified and it takes 20 milliseconds to service the page fault, in contrast it takes 12 milliseconds when the frame to be replaced has not been modified. It takes 100 nanoseconds to reference a physical memory location and we can neglect the time that it takes to access the page table. age fault occurs, 30% of the time an empty frame is not available and Calculate the effective memory access time for this system under these conditions. Clearly indicate intermediate steps
