Understanding Binary

Everything your computer does — every photo, message, and video — is built from just two digits: 0 and 1. This comprehensive, beginner-friendly guide takes you from "what is binary?" to confidently counting, converting, and understanding how computers use binary to store text, images, sound, and more. You'll learn why transistors make binary inevitable, master conversions between binary and decimal, explore hexadecimal shorthand, and discover how negative numbers work in two's complement. With clear illustrations, real-world examples, step-by-step walkthroughs, and practice problems with answers, this book makes the invisible language of computers visible. No experience required.
