This article mainly introduces the standard ascii code character set has a certain reference value, interested friends can refer to, I hope you can learn a lot after reading this article, the following let the editor take you to know about it.

The standard ascii character set has 128 encodings. Standard ASCII II codes represent one character with seven binary bits. Because the seventh power of 2 is 128, the standard ASCII code character set has a total of 128codes. Each code represents a basic symbol, that is to say, a maximum of 128basic symbols can be represented by ASCII codes.

The standard ascii character set has 128 encodings.

Because the computer can only accept, store and process binary numbers directly. The numerical information can be represented by binary code, while the non-numerical information must be expressed by binary coding. Coding refers to the combination of a small number of basic symbols according to certain rules to represent a large amount of complex and diverse information. Generally speaking, which words and symbols need to be represented by binary code depends on which words and symbols we require the computer to "recognize". In order to store the text and symbols in the computer, the text and symbols must be converted into binary codes according to the prescribed codes. At present, the ASCII code (American standard information interchange code) stipulated by the International Organization for Standardization is generally used to represent English letters and symbols in computers.

A standard ASCII code, usually called a 7-bit code, consists of a 7-bit binary code with the highest bit of 0. its range is 00000000000001111111 in binary and 011127in decimal system. Each code represents a basic symbol, that is, a maximum of 128 basic symbols can be represented by ASCII codes.

The standard ASCII code consists of a set of 3 bits and a group of 4 bits, with 7 columns in a group of 3 bits and 15 lines in a group of 4 bits. The behavior is ranked as 4 places low and 3 places high. An ASCII code can be fixed according to the column and row positions where the letters and numbers are located. For example, the letter An is in column 4, line 1, that is, the ASCII code is 01000001BCD. Similarly, a 7-bit ASCII can immediately find a corresponding number, letter, or symbol.

Thank you for reading this article carefully. I hope the article "what codes are shared by the standard ascii code character set" shared by the editor will be helpful to everyone. At the same time, I also hope that you will support us and pay attention to the industry information channel. More related knowledge is waiting for you to learn!
