Hello, everyone. The meeting will answer your questions. What is the data processed by the internal operation of the computer? the data run and processed inside the computer is something that many people do not know yet. now let's take a look at it.

Answer:

1. The data run and processed inside the computer is a binary number; a binary number: it is a number represented by the numbers 0 and 1. The cardinality is the carry rule "binary one", and the borrowing rule is "borrowing one into two". The operation rule is simple and consists of a logic circuit. The circuit has only two states and can only be represented by "1" and "0". The utility model has the advantages of simple operation, convenient conversion and good anti-interference effect.

2. The reasons why binary is used in computers:

3. First of all, the binary counting system uses only two numbers, 0, and so on. Any element with two different stable states can be used to represent a certain bit of a number, but in fact there are many elements with two obvious stable states, such as the "on" and "off" of neon lights, the "on" and "off" of switches, and the "high" and "low", "positive" and "negative" of voltage. The "hole" and "no hole" in the paper tape; the "signal" and "no signal" in the circuit; the north and south poles of magnetic materials. The list goes on and on; it's easy to realize that these completely different states are used to represent numbers. Not only that, but more importantly, there are differences not only in quantity but also in quality between these two completely different states. This can greatly improve the anti-interference ability and reliability of the machine, but it is much more difficult to find a simple and reliable device that can represent more than two states. Secondly, the four arithmetic rules of the binary counting system are very simple, and the four arithmetic operations can be summed up as addition and shift, which makes the arithmetic circuit in the electronic computer very simple. Not only that, the circuit is simplified, but also the speed can be improved, which is unmatched by the decimal counting system. Third, the use of binary representation in electronic computers can save devices, and it can be proved theoretically that ternary saves the most devices, followed by binary; however, because binary systems have advantages that other carry systems, including ternary systems, do not have, most electronic computers still use binary systems. In addition, because only two symbols "0" and "1" are used in binary, Boolean algebra can be used to analyze and synthesize logic 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 is convenient for the computer to carry out logical operations.

This is the end of this article. I hope it will be helpful to all of you.
