Question: 4. There is a paging system that has a paging disk of 1 TB capacity with a seek time, rotation speed, and data transfer rate

4. There is a paging system that has a paging disk

4. There is a paging system that has a paging disk of 1 TB capacity with a seek time, rotation speed, and data transfer rate of4 ms, 1500o RPM, and 8 MB/sec, respectively. A page is 16 o ns. Assume that when there is a page fault, the page to be replaced is dirty 80% of the time. Answer the following questions: (1) The average page fault service time when there is a page fault. (2) What is the maximum acceptable page fault rate for an effective access time of no more than 150 ns? Solution: 4.
