In mathematics and digital circuits, binary refers to a numeration system based on 2, which means that this system is binary. In this system, it is usually represented by two different symbols 0 (for zero) and 1 (for one).

Simplify operation

There are only three operation rules for addition and multiplication of binary numbers (0+0 = 0,0+1= 1+ 1 = 10 and 0× 0 = 0,0×1= 0.

Suitable for logical operation

There are only two numbers in binary, which coincides with the "truth" and "false" in logical algebra. Therefore, logical operations (AND, OR, NOT, judgment, comparison, processing, etc. ) can be executed more conveniently.

Easy conversion

Binary numbers can be easily converted into octal, hexadecimal and decimal.

Digital circuit adopts binary circuit, with only 0 and 1 two digits. With regard to decimal numbers, except for the decimal numbers commonly used now, China used to use hexadecimal in measurement, which is different from the decimal numbers used at present, but the calculation results are the same. The use of binary calculation in digital circuits is based on the early telegraph pulse principle.
