Difference between in-computer code and ascii code

In the computer, the difference between the Chinese character internal code and the English ASLl?

The difference between the internal code of a Chinese character and the national standard code is that the highest binary value of each byte of the former is 1, while that of the latter is 0. The code consisting of 0 and 1 symbols is used for storing, processing and transmitting Chinese characters in the computer. Once the input code is accepted, it is converted into the in-computer code by the “Input Code Conversion Module” of the Kanji operating system, independent of the keyboard input method used.

The internal code is the most basic code for Chinese characters. No matter what Chinese character system or Chinese character input method is used, the external code of the input Chinese characters has to be converted into the internal code inside the machine in order to be stored and processed.

What is the difference between GB code, in-computer code, external code and ASCII code? Thanks~~

The external code is also known as Chinese character input code.

ASCII is an internationally widely used character code for Western characters.

National Standard Code is the national standard for coding Chinese characters issued by China in 1981, and is used for coding Chinese characters.

The code used for Chinese character storage and operation inside a computer is called the in-computer code or internal code for Chinese characters.

Is the ascii code of a character the same as its internal code?

1, the internal code: according to the provisions of the national standard code, each Chinese character has a definite binary code, but this code will conflict with the ASCII code when it is processed in the computer, in order to solve this problem, the first byte of each byte of the national standard code is added with a 1. Since the ASCII code is only used with 7 bits, the first bit of “1” can be used as a symbol to identify the code of the Chinese character. Since ASCII code only uses 7 bits, the first “1” can be used as a symbol to recognize the code of Chinese characters, and the computer understands it as the information of Chinese characters when dealing with the code whose first bit is “1”, and understands it as the ASCII code when dealing with the code whose first bit is “0”. code.

2, external code: also called input code, is used to input Chinese characters into the computer a set of keyboard symbols. There are only 26 English alphabets, and it is possible to put all the characters on the keyboard, while it is impossible to put all the Chinese characters on the keyboard using this method. So the Chinese character system needs to have its own input code system so that the Chinese characters and the keyboard can establish a correspondence.

3, exchange code: the information processed inside the computer is expressed in binary code, and Chinese characters are no exception. And binary code is inconvenient to use, so the need to use information exchange code. China’s General Administration of Standards in 1981 developed the People’s Republic of China National Standard GB2312 – 80 “information exchange with Chinese characters coded character set – the basic set”, that is, the national standard code.

4. ASCII is a computer coding system based on the Latin alphabet. It is mainly used to display modern English and other Western European languages. It is the most common single-byte coding system in use today and is equivalent to the international standard ISO/IEC646.

What is the difference between the internal code and the external code of a computer

We often talk about the “internal code” and “external code” of Chinese characters.

The internal code is the information code used for storing, processing and transmitting Chinese characters inside the computer. It must be compatible with ascii code, but not conflicting with it.

So the highest position ‘1’ of the two bytes of the GB code to distinguish it from the western language is the internal code. The input code of Chinese characters is called “external code”. The input code is the code we use to input Chinese characters. Common external codes are numeric codes (e.g. area codes), pinyin codes, and character codes (e.g. Wubi).

The area code of “ah” is 1601, which is 0x10,0x01 in hexadecimal, which is in conflict with the ascii code widely used in computers.

The internal code is the character encoding inside the operating system. Early OS internal codes were language related . Nowadays windows has an internal standardization… We generally speak of the encoding specified by the default code page as the inner code,”.

There is the concept of default code page in windows://www; internal code”. So-called”. According to other coding interpretations.kth. it must be compatible with ascii code but not conflicting;text/.html”

target=”_blank”>http?, it can technically support multiple code pages at the same time.kth; the area code is 1601,0×01, the information code used for processing and transmission? For example, charset can be specified in html files. e.g. windows notepad opens a text file. We also call the encoding with two a0’s gb2312. For compatibility with the 00-7f

ascii encoding, there is no official definition. If he uses characters between 0x80-0xff and then adapts to various languages with code pages; the encoding becomes b0a1. as long as the file can indicate what encoding it uses,

d7.;content-type”. The code page is also just a Microsoft convention of calling it a mess????? .nada, we are in the area code of the high, Chinese windows and in accordance with the default gbk to interpret, or in accordance with the interpretation of big5, for example, d6?
