a number system in which each place is either 1 or 0. This is also called "Base 2" because each place is a power of two (the 2's place, the 4's place, 8's place, and so forth). All computer data is stored as binary data but is converted by the operating system to decimal numbers, text strings, color values, audio frequencies and more depending on the software application.

Number containing only I's or 0's.
