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
字节(Byte)是一种计量单位,表示数据量多少,它是计算机信息技术用于计量存储容量的一种计量单位,8个二进制位组成1个字节。在ASCII码中,一个标准英文字母(不分大小写)占一个字节位置,一个标准汉字占二个字节位置。 三.字符 字符是指计算机中使用的文字和符号,比如“1、2、3、A、B、C、~!·#￥%…*()+”等等。

() convert between characters and nonnegative integers representing the byte values. Bytes with the values 0-127 usually represent the corresponding ASCII values, but the interpretation of values is up to the program. The string data type is also used to represent arrays of bytes, e.g., to ...
