Frequently Asked Questions
What is the difference between program memory and data memory in von Neumann architecture?
Program memory is where the instructions that the CPU needs to execute are stored, while data memory is where the data that the CPU needs to process is stored.
How does the CPU access data and instructions in von Neumann architecture?
The CPU accesses data and instructions from memory through the memory bus, which is a shared communication pathway that connects the CPU and memory.
What is the role of the control unit in von Neumann architecture?
The control unit manages the flow of data and instructions within the CPU, ensuring that instructions are fetched, decoded, and executed in the correct order.
How does von Neumann architecture differ from Harvard architecture?
In Harvard architecture, program memory and data memory are physically separate and have their own communication pathways, while in von Neumann architecture, program memory and data memory share the same communication pathway.
What are the advantages of von Neumann architecture?
Von Neumann architecture is flexible and can execute programs stored in memory, which allows for efficient use of resources. Additionally, it is easy to implement and has become the basis for many computer technologies.
