The von Neumann architecture, proposed by the Hungarian mathematician and computer scientist John von Neumann in the mid-20th century, forms the foundation for most modern computer systems. This architecture is characterized by the integration of the CPU, memory, and input/output devices, all interconnected by a shared bus. The von Neumann machine's key components include the central processing unit (CPU), memory, control unit, and input/output devices.

### Components of von Neumann Architecture:

1. Central Processing Unit (CPU): The CPU is the brain of the computer and is responsible for executing instructions. It consists of an arithmetic logic unit (ALU) that performs arithmetic and logical operations and a control unit that manages the execution of instructions.

2. Memory: In the von Neumann architecture, both data and instructions are stored in the same memory. This memory is typically ____ _______ ______ ____ ____.
