The ascii code is stored in 1 byte in the computer. The ASCII code has a total of 128 characters. Each character corresponds to a numerical value, which is called the ASCII code value of the character; the computer uses one byte internally. (8 binary bits) stores a 7-bit ASCII code value.

How many bytes does the ascii code use to store in the computer?

The ascii code is stored in 1 byte in the computer.

Byte (Byte) is a unit of measurement used by computer information technology to measure storage capacity. It also represents data types and language characters in some computer programming languages. One byte stores an 8-bit unsigned number, and the stored value range is 0-255. Like characters, byte type variables only require one byte (8 bits) of memory space to store.

ASCII code has a total of 128 characters. Each character corresponds to a numerical value, which is called the ASCII code value of the character. The computer uses one byte (8 binary bits) to store a 7-bit ASCII code value.

Extended information:

Standard ASCII code, usually also called 7-bit code, consists of 7-bit binary code, the highest bit is 0, Its range is represented as 00000000~01111111 in binary and 0~127 in decimal, a total of 128 types. Each code represents a basic symbol. That is to say, ASCII code can be used to represent up to 128 basic symbols.

The 7-bit ASCII code is composed of a binary code of a group of 3 bits and a group of 4 bits. A group of 3 bits constitutes 7 columns, and a group of 4 bits constitutes 15 rows. The behavior is the lower 4 digits and the column is the upper 3 digits. According to the column and row positions of letters and numbers, an ASCII code can be fixed. For example: the letter A is located in column 4 and row 1, that is, the ASCII code is 01000001BCD. Similarly, given a 7-bit ASCII, a corresponding number, letter or symbol can be immediately found.
