Identify the correct order of the following list of computer components ranked from slowest to fastest in terms of access time. Choose the correct answer from the options given below.

1.CPU cache

2.RAM

3.SSD

4.Optical drive

A4, 3, 2, 1 ✓ Correct

B1, 2, 3, 4

C2, 1, 4, 3

D3, 4, 1, 2

Correct answer: (A) 4, 3, 2, 1

Explanation

Ordered from slowest to fastest access, the optical drive comes first, then the SSD, then RAM, and finally the CPU cache.

The optical drive is slowest because it reads spinning discs with a moving laser head.

An SSD is faster than optical media, using flash chips with no moving parts.

RAM is faster still, giving the processor quick electronic access to active data.

CPU cache is fastest, sitting closest to the processor to feed it instantly.

Access time shortens as storage moves nearer the processor in the memory hierarchy.
