Which component is NOT part of the Von Neumann architecture?

The Von Neumann architecture is a foundational model for designing computer systems and consists of several key components, including the central processing unit (CPU), memory, input devices, and output devices. This architecture emphasizes the use of a single storage structure to hold both data and instructions, allowing for efficient processing.

In this context, the graphics processing unit (GPU) falls outside the traditional components defined by the Von Neumann architecture. Originally, the architecture was conceptualized around a system where the CPU, which executes instructions, interacts with memory and I/O devices. The GPU, which is specialized for handling graphic rendering tasks, was developed later and operates alongside the CPU rather than being a core part of the Von Neumann model.

Therefore, recognizing that the GPU serves a distinct function focused on parallel processing for graphics, it is accurate to say that it is not a fundamental component of the Von Neumann architecture.
