Solution
The correct option is A 1.80ms
Suppose the time to
service a page fault is on the average 20 m s, while a memory access takes 5μ
sec than 91% hit ratio results in effective memory access time of 1.80ms.
A page fault is a type of exception raised by computer hardware when a
running program accesses a memory page that is not
currently mapped by the memory management unit (MMU) into the virtual address
space of a process.
