Suppose you're given there is a memory access time of 152 nanoseconds and an average page-fault service time of 15 milliseconds. a. If one access out of 2000 causes a page fault, what will be the Effective Access Time? b. How does this compare to main memory access time? Suppose you're given there is a memory access time of 356 nanoseconds and an average page-fault service time of 5 milliseconds. a. If one access out of 100 causes a page fault, what will be the Effective Access Time? b. How does this compare to main memory access time?
