What number system is used when data is transmitted, processed and stored within a computer?

When data is transmitted, processed and stored within the computer, the number system "binary" is used. The computer uses binary for data exchange and processing. The four arithmetic operations rules of the binary notation system are very simple, and the four arithmetic operations can ultimately be reduced to addition operations and shifts. In this way, the arithmetic circuits in electronic computers have also become very simple.

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 four arithmetic rules of the binary counting system are very simple. Moreover, the four arithmetic operations can ultimately be reduced to addition operations and shifts. In this way, the arithmetic circuits in electronic computers have become very simple. Not only that, the line is simplified and the speed can be increased. This is also incomparable to the decimal counting system.

The main reasons for using binary within computers are:

1. Simple technical implementation: computers are composed of logic circuits, and logic circuits usually only have two states. , the on and off of the switch, these two states can be represented by "1" and "0".

2. Strong anti-interference ability and high reliability: only two numbers 0 and 1 are used in binary, which is not prone to errors during transmission and processing, thus ensuring high reliability of the computer.

3. Simple operation rules: Compared with decimal numbers, the operation rules of binary numbers are much simpler, which not only simplifies the structure of the arithmetic unit, but also helps improve the operation speed.

4. Suitable for logical operations: Logical algebra is the theoretical basis for logical operations. Binary has only two digits, which coincides with "true" and "false" in logical algebra.

5. Easy to convert: Conversion between binary numbers and decimal numbers is quite easy. When people use computers, they can still use the decimal numbers they are accustomed to, and the computer automatically converts them into binary numbers for storage and processing. When outputting the processing results, it automatically converts the binary numbers into decimal numbers, which brings great convenience to work. .
