Binary coding is used inside the computer. Any information in the computer is represented by various combinations of "0" and "1". The reason for the use of binary is that the binary device is physically easy to implement, and the other is that in human thinking, the judgment of "yes" and "no" states is the most simple and stable.

The operating environment of this tutorial: windows7 system, Dell G3 computer.

Binary coding is used in the computer, and the data is processed, processed and transmitted in binary form.

Reason:

Binary coding is used in the transmission, storage and processing of information in the computer. the main reason is the feasibility, ease, simplicity, reliability and logic of using binary.

There are only two numbers 0 and 1 in binary coding, which can be easily expressed by two-state physical elements, that is to say, binary is used for data operation and processing in the computer, which is technically feasible and feasible.

There are few binary operation rules, the structure of the computer calculator can be greatly simplified, the control is correspondingly simple, the data transmission and processing are not easy to make mistakes, and the reliability of the computer is greatly improved.

The two digits 0 and 1 in binary coding can represent the "true" and "false" of logic algebra. By using binary system, it is convenient to use logic algebra as a tool to design the circuit and make the computer logical.

It is easy to convert, and binary and decimal numbers are easy to convert to each other.

Using binary to represent data has the advantages of strong anti-interference ability, high reliability and so on. Because each data has only two states, when subjected to a certain degree of interference, it can still reliably distinguish whether it is high or low.

Extended data:

(1) the basic concept of number system

Number system: the method of representing numerical values with a fixed set of numeric symbols and a unified set of rules is called a number system.

Cardinal number: in a numerical system, only a fixed set of numeric symbols can be used to represent the size of the number. The specific number of symbols used is called the cardinality of the numeral system, for example, the decimal cardinality is 10.

Bit weight: for multi-digits, the numerical value represented by a number on a bit is called the bit weight of that bit, for example, the bit weight of decimal thousand bits is 10 ^ 3.

(2) conversion of number system

Usually, most of them are represented by decimal numbers, but any data is represented by binary in the computer. Errors and omissions are easy to be found when reading and writing binary numbers, so hexadecimal numbers are often used to represent a binary number on some occasions.

Conversion of ① decimal numbers to other decimal numbers-- using the method of "dividing by cardinality to take the remainder in reverse order"

Conversion of ② other binary numbers to decimal numbers-- using the method of "expansion and accumulation by weight"

The interchange between ③ binary number and hexadecimal number-- using "8421" method
