Identify the correct order of the following memory types in decreasing order of access time.

1.RAM

2.SSD

3.CPU cache

A1, 3, 2

B3, 1, 2

C2, 3, 1

D2, 1, 3 ✓ Correct

Correct answer: (D) 2, 1, 3

Explanation

In decreasing access time the order is SSD, RAM then CPU cache, matching 2, 1, 3.

SSD has the longest access time, being the slowest of the three to reach.

RAM is faster than an SSD but slower than the processor's own cache.

CPU cache has the shortest access time, sitting closest to the processor.

Longer access time means data takes more time to be located and fetched.

Memory nearer the CPU is faster but costlier and smaller in size.
