Advantages of the Von Neumann Architecture:
- Simplicity: The architecture is relatively simple to design and implement, making it cost-effective.
- Flexibility: Because both instructions and data are stored in the same memory space, the architecture is flexible and can easily adapt to different types of programs.
- Cost-Effective: The shared memory space reduces the need for separate memory systems for instructions and data, leading to lower hardware costs.
Disadvantages of the Von Neumann Architecture:
- Von Neumann Bottleneck: The single data path between the CPU and memory creates a bottleneck, limiting the speed of data transfer. The CPU can only fetch either an instruction or data at any given time, not both simultaneously. This significantly impacts performance.
- Security Risks: Since both instructions and data reside in the same memory space, it can be more difficult to protect against malicious code that might try to modify instructions.
