In a paged memory, the page hit ratio is 0.40. The time required to access a page in secondary memory is equal to 120 ns. The time required to access a page in primary memory is 15 ns. The average time required to access a page is .
Correct Answer: D
Question 627 Explanation:
Average time to access a page = page hit ratio(time required to access a page in primary memory)+ page miss ratio(time required to access a page in primary memory+time required to access a page in secondary memory)
Average time to access a page = 0.40(15)+ 0.60(120)
Average time to access a page = 6+72
Average time to access a page = 78
Average time to access a page = 0.40(15)+ 0.60(120)
Average time to access a page = 6+72
Average time to access a page = 78
