Question: Consider a computer system that uses demand paging architecture. It takes 800 nanoseconds to serve a page fault if either an empty frame is available,

Consider a computer system that uses demand paging architecture. It takes 800 nanoseconds to serve a page fault if either an empty frame is available, or the page to be replaced is not dirty. It takes 950 nanoseconds to serve a page fault if the page to be replaced is dirty. Assume that average memory access time is 120 nanoseconds Further, is estimated that 85% of the time, the page to be replaced is dirty. What will be the approximate effective memory access time if the page fault rate is 0.2?
