Which of the following is not a component of Von Neumann architecture?

Solution (By Examveda Team)

Option A: CPU
This is a component of Von Neumann architecture. The CPU (Central Processing Unit) is responsible for executing instructions.

Option B: ALU
This is a component of Von Neumann architecture. The ALU (Arithmetic Logic Unit) performs arithmetic and logical operations.

Option C: Memory Unit
This is a component of Von Neumann architecture. The Memory Unit stores data and instructions that the CPU can access.

Option D: I/O Interface
This option is correct. The I/O Interface is not typically considered a core component of Von Neumann architecture. It facilitates communication between the computer and external devices but is not part of the fundamental CPU-memory interaction that defines Von Neumann architecture.

Conclusion:
Among the options given, Option D: I/O Interface is not a component of Von Neumann architecture, making it the correct answer.
