Domande frequenti

▾

Why do we use bases other than 10?

Computers use binary (base 2) and hexadecimal (base 16) for efficiency. Octal (base 8) was historically used in early computing.

What does hexadecimal stand for?

Hexadecimal means 16 (hex- = 6, -decimal = 10). It uses digits 0-9 and letters A-F.

How do I convert hex to binary quickly?

Each hex digit equals exactly 4 binary bits. F = 1111, A = 1010, etc.
