Binary number system

The binary number system is a positional numeral system with base 2. Each digit in a binary number represents a power of 2, with the rightmost digit representing $2^0$, the next $2^1$, and so on.

Important properties

• Only two digits are used: 0 and 1.

• Each position represents a different power of 2.

• Binary numbers can be converted to decimal by summing the products of each digit and its corresponding power of 2.

• Binary is the basis for how computers represent and process data.
