Which of the following statements are true?

1.Hard disk memory has the highest capacity

2.The central processing unit performs read or write operations directly with RAM

3.An algorithm is basically the logical flow of a program

A1 and 2

B1, 2 and 3 ✓ Correct

C2 and 3

D1 and 3

Correct answer: (B) 1, 2 and 3

Explanation

All three statements are correct.

Statement 1 rightly says hard disk memory has the highest capacity among common memories.

Statement 2 correctly says the central processing unit reads from and writes to RAM directly.

Statement 3 rightly calls an algorithm the logical flow of a program.

RAM is far faster than a hard disk but loses its data when power is off.

An algorithm is a step-by-step method for solving a problem.
