Hexadecimal Guide
Hexadecimal is a base-16 number system that extends decimal (0-9) with letters A-F representing values 10-15. Each hex digit maps to exactly 4 binary bits, making it a compact way to represent binary data.
Common uses include CSS color codes (#FF5733), memory addresses, Unicode code points (U+0041), MAC addresses (AA:BB:CC:DD:EE:FF), and byte-level data inspection.
