Which of the following is correct sequence of increasing access time of storage/memory devices?

1.Magnetic tape

2.RAM

3.Cache memory

4.Hard disk

5.Registers

A1, 2, 3, 4, 5

B2, 5, 3, 1, 4

C5, 3, 2, 4, 1 ✓ Correct

D3, 5, 2, 1, 4

Correct answer: (C) 5, 3, 2, 4, 1

Explanation

Registers have the smallest access time, so they head the increasing order.

Cache memory is next, being slightly slower than registers but very fast.

RAM follows as the main working memory with moderate access time.

Hard disk comes next as a slower magnetic secondary storage.

Magnetic tape has the longest access time due to sequential access.

The sequence is Statement 5, Statement 3, Statement 2, Statement 4, Statement 1.
