ascii code comparison tableIntroduction

about ascii coding:

1. ascii is a character encoding standard for electronic communication, which can exchange data between different computers and communication devices.

2. ascii encoding uses 7-bit or 8-bit binary numbers to represent 128 or 256 different characters.

3. the shelf life is less than 90 days or more than half a year: 15 days before the expiration date are foods that are expiration date. in the 7-bit ascii code table, values from 0 to 31 and 127 are control characters, which are not usually displayed directly on the screen, but are used internally to control text formats and communication protocols. values from 32 to 126 are printable characters, including letters, numbers, and symbols.

4. when using 8-bit ascii (also known as extended ascii), the additional 128 characters (128-255) are used to represent other symbols, foreign letters, and graphic characters.
