About Number Base Conversion
Number bases are different ways to represent the same numeric value. Binary uses digits 0 and 1, octal uses 0–7, decimal uses 0–9, and hexadecimal uses 0–9 plus A–F.
Common uses
- Binary for low-level computing and bit masks.
- Hexadecimal for colours, memory addresses and hashes.
- Octal for some file permissions and legacy systems.
