The ASCII table, or American Standard Code for Information Interchange, is a 7-bit character encoding system that represents 128 unique characters, including control and printable characters.

A complete list of all ASCII codes, characters, symbols and signs included in the 7-bit ASCII table and the extended ASCII table according to the Windows-1252 character set, which is a superset of ISO 8859-1 in terms of printable characters.

2022年6月2日 · ASCII 美国信息交换标准码的英文缩写。 Seven-bit ASCII表 示七位的ASCII 码，ASCII码的取值范围是0~127. 上个世纪60年代， 美国制定了一套字符编码， 对英语字符与二进制位之间的关系， 做了统一规定，这被称为ASCII码。 ASCII码一共规定了128个字符的编码， 比如空格“SPACE”是32（二进制00100000）， 大写的字母A是65（二进制01000001）。 这128个符号（包括32个不能打印出来的控制符号）， 只占用了一个字节的后面7位， 最前面的1位统一 …

ASCII was incorporated into the Unicode (1991) character set as the first 128 symbols, so the 7-bit ASCII characters have the same numeric codes in both sets. This allows UTF-8 to be backward compatible with 7-bit ASCII, as a UTF-8 file containing only ASCII characters is identical to an ASCII file containing the same sequence of characters.

7-bit refers to a numbering system that uses 7 binary digits (bits) to represent numbers and other data. Each binary digit can have two values: 0 or 1. In a 7-bit system, there are 2^7, or 128, possible combinations of 0s and 1s, and each combination can represent a different number, character, or other unit of data.

2011年6月13日 · 字符编码转换的工具（根据3GPP 03.38,11.11附录等协议），可以把字符转换成ascii，8 bit，7 bit，UCS2，UTF-8编码。 在做手机软件开发的时候，调试WMS，Phone book，STK等模块可能会用的到。

2017年2月11日 · 每一个二进制位（bit）有0和1两种状态，因此八个二进制位就可以组合出256种状态，这被称为一个字节（byte）。 也就是说，一个字节一共可以用来表示256种不同的状态，每一个状态对应一个符号，就是256个符号，从0000000到11111111。 上个世纪60年代，美国制定了一套字符编码，对英语字符与二进制位之间的关系，做了统一规定。 这被称为ASCII码，一直沿用至今。 ASCII码一共规定了128个字符的编码，比如空格”SPACE”是32（二进制00100000）， …

2024年11月28日 · ASCII uses a 7-bit character encoding system to represent 128 unique characters, which include both control characters and printable characters. The first 32 code points (numbers 0-31 in decimal) and the last one (number 127 in decimal) are reserved for...

2023年10月18日 · By using 7 bits, ASCII could represent a wide range of characters, including uppercase letters, lowercase letters, numbers, punctuation marks, and control characters. These characters were deemed essential for basic text manipulation and communication purposes.
