Von Neumann Computer Model Fundamentals
📌 The Von Neumann architecture, developed by John Von Neumann in 1945, is the foundation for most modern computers.
💾 This model describes a computer system comprising a Central Processing Unit (CPU), memory, and input/output (I/O) devices.
🔄 A key feature is that both programs and data are stored in the same memory, enabling sequential instruction execution.

Core Components and Functionality
💻 The architecture operates on three main interacting components: Input, Process, and Output.
📥 Input involves feeding data and instructions (like text, images, or sound) into the system via devices such as keyboards, mice, or microphones.
🧠 The Process stage centers on the CPU, which contains the Control Unit (managing data flow) and the Arithmetic Logic Unit (ALU) for performing mathematical and logical operations.
📊 Output delivers the processed results—such as text on a monitor or printed reports—back to the user or stores them for later use.

Architecture Implications and Limitations
🛠️ The Von Neumann concept allows for flexibility and efficiency in data processing due to its unified memory structure.
🐌 A significant limitation is the Von Neumann bottleneck, which refers to the constraint caused by the data transfer speed between the CPU and memory.

Key Points & Insights
➡️ Understand that the core function of the computer involves a continuous cycle of input $\rightarrow$ processing $\rightarrow$ output.
➡️ Recognize the CPU's dual role in managing instruction flow (Control Unit) and executing calculations (ALU).
➡️ Be aware of the Von Neumann bottleneck as a critical trade-off in modern computer design efficiency related to memory access.
