About Hexadecimal Codes
Hexadecimal (base-16) is a numeral system that uses 16 distinct symbols: 0-9 for values zero to nine, and A-F (or a-f) for values ten to fifteen. It's commonly used in computing for its compact representation of binary data.
Hex Format
Each hexadecimal digit represents 4 bits (half a byte), making it convenient for representing byte values.
