Which of the following components are part of the central processing unit (CPU) of the Von Neumann model for a computer system?

1.Arithmetic Logic Unit (ALU)

2.Hard Disk Drive (HDD)

3.Memory Address Register (MAR)

4.Solid State Drive (SSD)

5.Control Unit (CU)

A1 & 5 only

B2, 3 & 4 only

C1 & 3 only

D1, 3 & 5 only ✓ Correct

Correct answer: (D) 1, 3 & 5 only

Explanation

Statement 1 is correct, as the Arithmetic Logic Unit is part of the CPU in the Von Neumann model.

Statement 2 is wrong, since the Hard Disk Drive is secondary storage, not part of the CPU.

Statement 3 is correct, as the Memory Address Register is a CPU register.

Statement 4 is wrong, since the Solid State Drive is storage, not a CPU component.

Statement 5 is correct, as the Control Unit is a core part of the CPU.

The ALU, registers and Control Unit together make up the processor in this model.
