💡 Quick Reference
- • Binary: base 2 — only 0 and 1. Each bit doubles. 8 bits = 1 byte.
- • Octal: base 8 — digits 0–7. Common in Unix file permissions (chmod 755).
- • Hex: base 16 — 0–9 then A–F. Two hex digits = one byte. Widely used in color codes & memory addresses.
- • 0xFF = 255 dec = 11111111 bin = one full byte
- • 0xDEADBEEF = 3,735,928,559 dec — classic debugger sentinel value
