Question

If a memory reference takes 100 nanoseconds, how long does a paged memory reference take?

Answer 1

Answer: 200 nanoseconds

Explanation:

If a memory reference is taking 100 nanoseconds

Then, a paged memory references take two memory access which are getting the number of frame from the memory for page number and followed by this accessing of the data/information.

Thus, the time taken by the paged memory reference is

Time= 2$\times$100 nanoseconds

Time=200 nanoseconds
