I. Concept of Modulo (I will only list one example. For details, refer to "same-modulus" in mathematics ")In daily life, there are many examples of subtraction and addition. For example, the clock runs at 12 bits, and can also be regarded as zero.There are two ways to adjust the hour hand from: Ii. Use of the modulo (using the modulo to obtain the complement code)1,The following code is obtained:To convert

What is a number system? Rules used to represent numeric values, such as decimal and binary. Machine count Represents a number in binary format. The highest digit is the sign bit. 1 indicates a negative number, and 0 indicates a positive number. For example: 1 ----> 00000001;-1 ----> 1000 0001True Value We can see from the above that the number of machines is a form of computer used to represent the number, but the maximum bit is a symbol. In this case, 1000 0001 represents 1 rather than 129. In

Concept of Modulo (I will only give an example to illustrate how to look up the concept of "same-modulus" in mathematics ")In daily life, there are many examples of subtraction and addition. For example, the clock runs at 12 bits, and can also be regarded as zero.There are two ways to adjust the hour hand from 10 to 5:1. Set the clockwise direction to 5 cells, which is equivalent to subtraction: 10

One: Ordinary code block1 //Ordinary code block: {} that appears in a method or statement is called a normal code block . ordinary blocks of code and general execution order of statements are determined by the order in which they appear in the code-"first Occurrence first" 2

The Code 39 code rules are:1, each five line represents a character;2, The thick line is 1, the thin wire represents 0;3, the gap between lines of the width of the expression 1, a narrow representation of 0;4, five lines plus the four gap between them is nine-bit binary encoding, and this nine bit must have three bits is 1, so called 39 yards;5, the first and last of the bar

Why? The computer uses binary to represent a value. For example, decimal number 10 is expressed as 1010 in binary number. Set the computer to 8 characters, that is, 1 byte. The highest digit indicates the symbol. 0 is positive and 1 is negative.Let's take a look at the problems with the addition, subtraction, multiplication, division, and number represented by the original code: Decimal: 1-1 = 1 + (-1) = 0 Original

Recently reported a soft test, the basic knowledge of evil, the previous learned the original code, anti-code, the complement unexpectedly forget, there are not familiar with the shift code, deliberately spend some time to organize, hope to help everyone.

In a computer system, integers are all expressed (stored) by supplementary codes ). In a computer, integers are represented by supplementary codes. the symbol bit and other bits can be processed in a unified manner, and the subtraction can also be processed by addition. In addition, when two bits are added, if the highest bit (symbol bit) has an inner, the carry is discarded. Therefore, you only need to deploy the addition circuit and the complement circuit in the computer to complete the additi

In 1980, in order to make each Chinese character have a unified national code, China issued a Chinese character encoding National Standard: GB2312-80 "information exchange with Chinese character encoding Character Set-basic set", this character set is the unified standard for all Chinese character systems in China. It specifies that two bytes are used to represent a Chinese character. Each byte can only use a minimum of seven characters, with a total
