What base system is used internally by the computer to represent data?

Computers use binary to represent data internally. Binary in mathematics and digital circuits refers to a 2-based numbering system, usually represented by two different symbols 0 and 1. Binaries are used in modern computers and computer-dependent devices.

The internal calculation of the computer uses binary representation of data.

Binary (binary) refers to a numbering system based on 2 as the base in mathematics and digital circuits. Using 2 as the base means that the system is binary. In this system, it is usually represented by two different symbols: 0 (representing zero) and 1 (representing one). In digital electronic circuits, the implementation of logic gates directly uses binary, so modern computers and computer-dependent devices all use binary. Each number is called a bit.

Binary operations:

Addition

There are four cases of binary addition: 0 0=0, 0 1=1, 1 0=1, 1 1=10(0 Carry is 1).

Multiplication

There are four cases of binary multiplication: 0×0=0, 1×0=0, 0×1=0, 1×1=1.

Subtraction

There are four situations in binary subtraction: 0-0=0, 1-0=1, 1-1=0, 0-1=1.

Division

There are two cases of binary division (the divisor can only be 1): 0÷1=0, 1÷1=1.
