Consider a demand-paged computer system where the degree of multiprogramming is currently fixed at five. The system was recently measured to determine utilization of the CPU and the paging disk. Three alternative results are shown below. For each case, what is happening? Can the degree of multiprogramming be increased to increase the CPU utilization? Is the paging helping? Justify CPU utilization 7 percent; disk utilization 97 percent CPU utilization 95 percent; disk utilization 3 percent CPU utilization 13 percent disk utilization 6 percent
