Q1) Consider a demand-paging system with a paging disk that has an average access and transfer time of 20milliseconds. Addresses are translated through a page table inmainmemory, with an access time of 1microsecond per memory access. Thus, eachmemory reference through the page table takes two accesses. To improve this time, we have added an associativememory that reduces access time to one memory reference, if the page-table entry is in the associative memory. Assume that 80 percent of the accesses are in the associative memory and that, of the remaining, 10 percent (or 2 percent of the total) cause page faults.What is the effective memory access time?
