Caching: Assume a computer system employing a cache, where the access time to the main memory is 100 ns, and the access time to the cache is 20ns.Assume the system implements virtual memory using a two--level page table with no TLB, and assume the CPU loads a word X from main memory. Assume the cache hit ratefor the page entries as well as for the data in memory is 95%. What is the average time it
takes to load X?
