Question

Which of these trade-offs occur in a memory hierarchy?

a.
Longer addresses mean faster access

b.
Longer addresses mean smaller memory size

c.
Closer to CPU means larger memory size

d.
Faster access means smaller memory size

Answer 1

Answer: D) Faster access means smaller memory size

Step-by-step 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.
