Understanding Logic Gates

Every device you use — from your phone to your laptop — runs on billions of tiny decision-makers called logic gates. But what are they, and how do they work? This beginner-friendly guide walks you through all seven fundamental gates — AND, OR, NOT, NAND, NOR, XOR, and XNOR — with clear diagrams, real-world analogies, and easy-to-read truth tables. You'll also learn how gates combine to build real circuits, the basics of Boolean algebra, and De Morgan's theorems. Packed with illustrations, practice problems, and a complete glossary, this book makes digital electronics click. No prior knowledge needed.
