Question #7: (5 marks) Consider a demand-paging system where addresses are translated through a page table in main memory, with an access time of 300ns per memory access. Thus, each memory reference through the page table takes two accesses. To improve this time we have added translation look aside buffer that reduces access time to 45ns. Assume that 95 percent of the accesses are from the translation look aside buffer. What is the effective memory access time
