📚 Topic Summary
Binary numbers are the foundation of how computers store and process information. Unlike our everyday decimal system (base-10) which uses ten digits (0-9), the binary system (base-2) uses only two digits: 0 and 1. Each 0 or 1 is called a bit. Computers use these bits to represent everything from numbers and letters to images and sounds.
Think of it like a light switch: it can be either on (1) or off (0). By combining multiple switches (bits), computers can represent complex data. Understanding binary is key to understanding how computers work their magic! ✨
