Binary (Base-2): Uses digits 0 and 1. fundamental representation of digital logic circuits.
Octal (Base-8): Uses digits 0 to 7. Common in Unix file permission representation (e.g. chmod 755).
Decimal (Base-10): Standard human numerical system (digits 0 to 9).
Hexadecimal (Base-16): Uses 0-9 and A-F. Widely used for memory addresses, CSS color codes, and byte inspection.
