How binary works: The binary number system (aka base 2) represents values using two symbols, typically 0 and 1. Computers call these bits. A bit is either off (0) or on (1). When arranged in sets of 8 bits (1 byte) 256 values can be represented (0-255). Using an ASCII chart, these values can be mapped to characters and text can be stored. It's not magic, it's just math!
