Answer: D) Faster access means smaller memory size
Explanation:
In memory hierarchy, one of the most important point is that the trade off between the speed, size and cost.
The smaller the size of memory means fastest access. If the memory is close to the central processing unit (CPU) then, there is fastest access in the memory. Memory hierarchy directly fetch the information or data from the memory processor.
Cache memory, CD-ROM and random access memory (RAM) are the basic layers of memory hierarchy.
