Hexadecimal Number System
Hexadecimal compresses long binary strings into something people can scan quickly. It is widely used in memory views, color codes, encodings, and low-level debugging.
Why Hex Works Well
4 bits per digit
Each hexadecimal character maps exactly to one nibble, which makes binary conversion fast and predictable.
Compact format
`11111111` is much easier to scan as `FF`, especially in logs, dumps, and configuration values.
Real-world usage
Memory addresses, color values, packet data, hashes, and file headers often appear in hexadecimal.
