Character encoding is the cornerstone of computer technology. To be familiar with computers, you must understand a little bit about character encoding. 1. ASCII code We know that in a computer, all information is eventually represented as a binary string. Each binary bit has two states: 0 and 1. Therefore, eight binary bits can combine 256 states, which is called a byte ). That is to say, a single byte can be used to represent 256 different States

1 ASCII codeThe relationship between English characters and bits is uniformly stipulated. The ASCII code altogether specifies a 128-character encoding. For example, the space "space" is 32 (binary 00100000), and capital A is 65 (binary 01000001). These 128 symbols (including 32 control symbols that cannot be printed out) occupy only one byte of the following 7 bits, and the first 1-bit uniform is 0.2 Non-
