How Logic Gates Work — From Binary to CPUs and Computers #LogicGates #DigitalLogic #CPU

How can computers perform calculations, run operating systems, display videos, and power artificial intelligence using only zeros and ones? The answer begins with logic gates. Logic gates are tiny electronic circuits that receive binary inputs, follow fixed rules, and produce binary outputs. By combining millions or billions of these simple circuits, engineers can build adders, registers, memory systems, ALUs, CPUs, GPUs, and complete computers. In this video, you will learn: How electrical signals represent binary 0 and 1 What a logic gate is How truth tables describe logic-gate behavior How the NOT gate inverts a signal How the AND gate works How the OR gate works How the XOR gate detects different inputs How NAND and NOR gates work Why NAND and NOR are called universal gates How transistors create logic gates How logic gates form larger digital circuits How XOR and AND gates create a half adder How logic gates help build the ALU, registers, memory, and CPU The main gates covered are: NOT, AND, OR, XOR, NAND, and NOR A single logic gate performs a very simple operation. But when billions of gates work together, they create the modern digital world. Transistors → Logic Gates → Adders → ALU → CPU This video is suitable for anyone learning computer architecture, digital electronics, FPGA design, embedded systems, binary arithmetic, or how computers work.
