Which of the following statements are true?

1.The CPU can store data for a long time

2.Increasing the amount of RAM will increase the performance of the computer

3.RAM is known as volatile memory

4.ROM is the processing unit

5.The CPU is known as the brain of the computer

A2, 3 & 5 only ✓ Correct

B1, 3 & 4 only

C1, 4 & 5 only

D2, 3 & 4 only

Correct answer: (A) 2, 3 & 5 only

Explanation

The true set is that adding RAM improves performance, RAM is volatile, and the CPU is the brain of the machine.

Statement 1 is wrong because the CPU only processes data momentarily and cannot store it for long.

Statement 2 is right since extra RAM lets more programs and data stay ready for quick use.

Statement 3 is right because RAM loses its contents once the power is removed.

Statement 4 is wrong as ROM is read-only storage, not the processing unit.

Statement 5 is right because the CPU directs and carries out all computer operations.

Long-term storage instead belongs to the hard disk or SSD, not the CPU.
