Number Base Converter
While humans have settled on the decimal system (Base 10) because we have ten fingers, computers operate on logic gates that are either "on" or "off," leading to the binary system (Base 2). Understanding how to jump between these bases is a foundational skill for programmers, network engineers, and students of digital logic.
The Systems Explained
- Binary (Base 2): The absolute core of computing. Only uses 0s and 1s.
- Octal (Base 8): Used in some legacy systems and Unix file permissions. Uses digits 0–7.
- Decimal (Base 10): Our standard counting system using 0–9.
- Hexadecimal (Base 16): Essential for colors and memory addresses. Uses 0–9 and letters A–F.
