What are Number Bases?
A number base (or radix) is the number of unique digits used to represent numbers in a positional numeral system. The most common bases in computing are:
- Binary (Base 2): Uses 0 and 1. The fundamental number system for computers.
- Octal (Base 8): Uses 0-7. Common in Unix file permissions.
- Decimal (Base 10): Uses 0-9. The standard human-readable number system.
- Hexadecimal (Base 16): Uses 0-9 and A-F. Common for colors, memory addresses, and data representation.
Common Use Cases
- Programming: Convert between number systems for bitwise operations
- Color Codes: Convert RGB values to hexadecimal color codes
- Memory Addresses: Work with hexadecimal memory addresses
- File Permissions: Convert between octal and binary permissions
- Network Masks: Convert IP subnet masks between formats
- Data Encoding: Convert data to base64 for transmission
