Frequently Asked Questions

How do you read a binary number?▾

Each binary digit (bit) represents a power of two, starting at 2⁰ for the rightmost bit. Add the powers for every bit that is 1; 1010₂ is 8 + 0 + 2 + 0 = 10.

Why are octal and hexadecimal used with computers?▾

Octal and hexadecimal are shorthand for binary: one hex digit equals four bits and one octal digit equals three bits, making long binary values far easier to read.
