About Number Systems
Binary (Base 2)
Uses only two digits: 0 and 1. Widely used in computing and digital systems because it can be easily represented by electronic switches (on/off).
Decimal (Base 10)
The standard number system used by humans. Uses ten digits from 0 to 9. Each digit's position represents a power of 10.
Hexadecimal (Base 16)
Uses 16 symbols: 0-9 and A-F. Commonly used in computing to represent binary data in a more compact and human-readable form.
Octal (Base 8)
Uses eight digits from 0 to 7. Historically used in computing, though less common today compared to hexadecimal.
