What is the number system used internally by computers?

The number system used inside the computer is "binary". The computer uses binary for data exchange and processing internally; the four arithmetic rules of the binary counting system are very simple, and the four arithmetic operations can ultimately be attributed to addition operations and shifts. In this way, the arithmetic circuits in electronic computers have also become very simple. . Simply put, binary number operations are simple, which greatly simplifies the structure of the computing components in calculations.

The number system used inside the computer is "binary".

When data is transmitted, processed and stored within the computer, the number system "binary" is used.

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.

There are few binary operation rules, the structure of the computer operator can be greatly simplified, the control is correspondingly simple, the transmission and processing of data are not prone to errors, and the working reliability of the computer is greatly improved.

The reason why the number system used inside the computer is "binary":

• The information transmission, storage and processing inside the computer all use binary coding , the main reasons are the feasibility, ease, simplicity, reliability and logic of using binary.

• There are only two digits, 0 and 1, in binary coding, which can be easily represented by two-state physical components. That is to say, the computer uses binary for data operations and processing. Technology It is feasible and easy to do.

• There are few binary operation rules, the structure of the computer operator can be greatly simplified, the control is correspondingly simple, the transmission and processing of data are not prone to errors, and the working reliability of the computer is greatly improved.

• The two numbers 0 and 1 in binary coding can represent the "true" and "false" of logical algebra. Using binary, it is easy to use logical algebra as a tool to conduct circuits. Design to make computers logical.

• Easy to convert, binary and decimal numbers are easy to convert to each other.

• Using binary to represent data has the advantages of strong anti-interference ability and high reliability. Because each bit of data has only two states: high and low, when it is disturbed to a certain extent, it can still be reliably distinguished whether it is high or low.
