Suppose the time to service a page fault is on the average 10 ms, while a memory access takes 1 ms. Then, a 99.99% hit ratio result in average memory access time of
-
- 1.9999 ms
- 1 ms
- 9.999 ms
- 1.9999 ms
- 1.9999 ms
Correct Option: D
Since, hit ratio = 99.99%
It will make 0.9999 ms.
Therefore, Average memory access time for 99.99% hit ratio
= Memory access time + 0.9999 = 1 ms + 0.9999 ms
= 1.9999 ms
