The Brain on a Chip

Hook about the CPU processing billions of instructions.

💡 The CPU inside a modern smartphone can perform billions of arithmetic operations in a single second. It is the undisputed brain of the computer system, coordinating every single click, swipe, and keystroke.

Core Architecture

The CPU and Its Components

Explanation of ALU, CU, and Registers based on Von Neumann.

The Central Processing Unit (CPU) is the electronic circuitry carrying out the actual processing, often referred to as the brain of the computer. Physically, it is placed on one or more microchips called Integrated Circuits (ICs).

Von Neumann Architecture

Block diagram of computer components.

clean scientific diagram, pastel color palette, elegant typography, precise labeling, translucent layers for cross-sections, white background, soft shadows. Diagram of the Von Neumann architecture showing a central large block for CPU containing Control Unit (CU) and Arithmetic Logic Unit (ALU). A block for Primary Memory is placed nearby, and Secondary Storage Devices point towards the Primary Memory. An Input Device block points in to the system, and an Output Device block points out. Directed arrows represent the flow of data and control signals between components.

The CPU is given instructions and data through programs which it fetches from the main memory. While processing, the CPU stores intermediate results and instructions in its local memory called. These memory locations are part of the CPU chip itself and are limited in size and number. Other than this local memory, the CPU has two primary components responsible for executing programs. Theperforms all the math and logic operations required by the program's instructions. Conversely, theinterprets these instructions and controls sequential execution. This component also guides thethrough the computer's memory, processor, and peripheral devices.

Input & Output Devices

Explanation of devices converting digital to human-readable and vice versa.

A computer system relies on peripheral devices to communicate with the outside world. Without them, we couldn't send instructions or see the results.
