Binary System

Binary is a number that includes only one and zero. Also called base-2. The "position values" in a binary number are the powers of two like 2, 4, 8, 16, 32, 64, 128, etc.
*Bi means "two" in Latin


Decimal is the numbers that we are used to seeing. Consist of numbers from 0-9. Also called base-10.

(Note: Every Binary number has a corresponding Decimal value (and vice versa).)
