This article mainly introduces that a space in the computer occupies several characters, which has a certain reference value. Interested friends can refer to it. I hope you will gain a lot after reading this article. Let's take a look at it with you.

A space occupies one character, and the characters include letters, numbers, arithmetic symbols, punctuation and other symbols, as well as some functional symbols; characters stored in the computer should specify the corresponding binary code to represent the characters.

1. Space occupies one character

two。 One Chinese character takes up two characters.

3. One letter takes up one character.

4. GB and GBK encodings are 1 character and 2 bytes.

5. UTF8 encoding is 1 character and takes 3 bytes.

6. Unicode encodings are 1 character and 4 bytes.

7. Different encoding intervals are used to represent different bytes.

Characters include letters, numbers, arithmetic symbols, punctuation marks and other symbols, as well as some functional symbols. When the characters are stored in the computer, the corresponding binary code representing the characters should be specified. The selection of the code should be consistent with the specifications of the relevant peripheral equipment. These peripheral devices include the input and output of the keyboard console, the output of the printer and so on. When characters are input, the binary code is automatically converted to binary code and stored in the machine; when output, the binary code in the computer is automatically converted into characters, both of which are realized by peripheral equipment. A character is the smallest data access unit in a data structure. A character is usually represented by eight binary bits (one byte), but a few computer systems use a six-binary character representation. The size of the character set in a system is entirely determined by the system itself. Generally speaking, there are 128 characters available to the computer (excluding Chinese characters). After entering the computer, each character will be converted into 8-bit binary numbers. Different computer systems and different languages can use different ranges of characters.

In ASCII encoding, it takes 1 byte to store an alphabetic character. In GB 2312 coding or GBK coding, it takes 2 bytes to store a Chinese character. In UTF-8 coding, it takes 1 byte to store an English alphabetic character and 3 to 4 bytes to store a Chinese character. In UTF-16 coding, the storage of an English alphabetic character or a Chinese character requires 2 bytes (some Chinese characters in the Unicode extension need 4 bytes). In UTF-32 encoding, the storage of any character in the world requires 4 bytes.
