Question

Which of the following is true about Von Neumann architecture?

• A. It has separate storage for input/output operations
• B. It has a separate processing unit for data and instructions
• C. It has separate memory for data and instructions
• D. It has a single memory unit for both data and instructions

Hint:

In Von Neumann architecture, both instructions and data are stored in the same memory, and they are processed by a single processing unit.

Answer 1

The Correct Option is D

Step 1: Understand Von Neumann Architecture.
Von Neumann architecture is a computer architecture where both program instructions and data share the same memory and are accessed through the same system bus. This is also known as the "stored-program" concept.

Step 2: Analyze the options.
- (a) Incorrect. In Von Neumann architecture, input/output operations do not have separate storage. They are part of the system as a whole.
- (b) Incorrect. The Von Neumann architecture uses a single processing unit for both data and instructions. There is no separate processing unit.
- (c) Incorrect. Memory is shared for both data and instructions in Von Neumann architecture. There is no separate memory.
- (d) Correct. Von Neumann architecture uses a single memory unit for both data and instructions.

Step 3: Conclusion.
Thus, the correct answer is (d), as Von Neumann architecture uses a single memory unit for both data and instructions.
