Number Systems and Conversions

Computers don't work with ten digits; they use binary (base-2), which only has two digits: 0 and 1. This is because computers operate on electrical signals being either "on" or "off." Each binary digit is called a bit.

Other common number systems in computing are octal (base-8, digits 0-7) and hexadecimal (base-16, digits 0-9 and A-F, where A=10, B=11, etc.). These are often used as shorthand for binary numbers because they're easier for humans to read and write.
