O sistema binário ou de base 2 é um sistema de numeração posicional em que todas as quantidades se representam com base em dois números, ou seja, zero e um (0 e 1). [ 1][ 2] Os computadores digitais trabalham internamente com dois níveis de tensão, pelo que o seu sistema de numeração natural é o sistema binário. [ 3]
A binary number is a number expressed in the base -2 numeral system or binary numeral system, a method of mathematical expression which uses only two symbols: typically "0" ( zero) and "1" ( one ). 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.
The binary numeral system is a way to write numbers using only two digits: 0 and 1. These are used in computers as a series of "off" and "on" switches. In binary, each digit's place value is twice as much as that of the next digit to the right (since each digit holds two values).
In computers, the main numeral systems are based on the positional system in base 2 ( binary numeral system ), with two binary digits, 0 and 1. Positional systems obtained by grouping binary digits by three ( octal numeral system) or four ( hexadecimal numeral system) are commonly used.
List of numeral systems. There are many different numeral systems, that is, writing systems for expressing numbers . By culture / time period. By type of notation. Numeral systems are classified here as to whether they use positional notation (also known as place-value notation), and further categorized by radix or base.

The numbers from 0 to 10 are thus in binary 0, 1, 10, 11, 100, 101, 110, 111, 1000, 1001, and 1010.
