A '''binary number''' is a [[number]] expressed in the '''[[Radix|base]]-2 [[numeral system]]''' or '''binary numeral system''', a method for representing [[number]]s that uses only two symbols for the [[natural number]]s: typically "0" ([[zero]]) and "1" ([[one]]). A ''binary number''  may also refer to a [[rational number]] that has a finite representation in the binary numeral system, that is, the quotient of an [[integer]] by a power of two.

The base-2 numeral system is a [[positional notation]] with a [[radix]] of [[2]]. Each digit is referred to as a [[bit]], or binary digit. Because of its straightforward implementation in [[digital electronic circuit]]ry using [[logic gate]]s, the binary system is used by almost all modern [[computer|computers and computer-based devices]], as a preferred system of use, over various other human techniques of communication, because of the simplicity of the language and the noise immunity in physical implementation.<ref>{{cite web |title=3.3.
