This article mainly introduces how to access and transmit all the information in the computer. It is very detailed and has a certain reference value. Friends who are interested must finish reading it.

The access, processing and transmission of all information in the computer are carried out in "binary". In the representation of data in a computer, the internal data representation of the computer; the reason why the computer uses binary to access, process and transmit data is due to the characteristics of binary itself: feasibility, simplicity, logic and reliability.

In mathematical and digital circuits, binary refers to a numbering system based on 2, which represents a binary system. In this system, it is usually represented by two different symbols 0 (for zero) and 1 (for one). In digital electronic circuits, binary is directly used in the implementation of logic gates, so binary is used in modern computers and computer-dependent devices. Each number is called a bit (abbreviation for Bit,Binary digit).

The reason why the computer uses binary to access, process and transmit data is because of its own characteristics: feasibility, simplicity, logic and reliability.

In the field of computers, we use binary to count because binary has the following advantages:

1) there are only two digits 0 and 1 in the binary number, and one digit can be represented by components with two different stable states. For example, the current of a certain path in the circuit, the voltage of a node, the turn-on and cut-off of the transistor, and so on.

2) the binary number operation is simple, which greatly simplifies the structure of the operation unit in the calculation.

There are four basic algorithms for addition and multiplication of binary numbers, as follows:

0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,

0 × 0 × 0 × 1 × 0 × 0 × 0 × 0 × 0 × 0 × 0 × 1 × 1 × 1

3) binary is naturally compatible with logical operations.

Reasons for the use of binary in computers

First, the binary counting system uses only two digits. 0 and 1, so any element with two different stable states can be used to represent a bit of a number. In fact, there are many elements with two obvious stable states. For example, the "on" and "off" of the neon lamp, the "on" and "off" of the switch, the "high" and "low", "positive" and "negative" of the voltage, the "hole" and "no hole" in the paper tape, the "signal" and "no signal" in the circuit, the South Pole and North Pole of magnetic materials, and so on. It is easy to use these distinct states to represent numbers. Not only that, but more importantly, the two completely different states differ not only in quantity, but also in quality. In this way, the anti-interference ability and reliability of the machine can be greatly improved. It is much more difficult to find a simple and reliable device that can represent more than two states.

Secondly, the four operation rules of the binary counting system are very simple. And the four operations can be summed up as addition and shift, so the circuit of the arithmetic unit in the electronic computer becomes very simple. Not only that, the circuit is simplified, the speed can be improved. This is also not comparable to the decimal counting system.

Third, the use of binary representation in electronic computers can save equipment. It can be proved theoretically that ternary system is the most economical equipment, followed by binary system. However, because binary system has advantages that other carry systems, including ternary system, do not have, most electronic computers still use binary system. In addition, because only two symbols "0" and "1" are used in binary, Boolean algebra can be used to analyze and synthesize logical circuits in machines. This provides a very useful tool for designing electronic computer circuits.

Fourth, the binary symbols "1" and "0" correspond to "true" and "false" in logical operations, which are convenient for computers to carry out logical operations.
