Frequently Asked Questions
What are number bases?
A number base (or radix) is the number of unique digits used to represent numbers. Binary (base 2) uses 0-1, Octal (base 8) uses 0-7, Decimal (base 10) uses 0-9, and Hexadecimal (base 16) uses 0-9 and A-F.
Why is hexadecimal used in programming?
Hexadecimal is compact (one hex digit represents 4 binary digits) and easy to convert to/from binary. It's commonly used for memory addresses, color codes, and debugging.
