And other similar error checking code, Hamming code also makes use of the concept of parity, data bits followed by an increase in the number of bits, can verify the validity of data.
与其他的错误校验码类似，汉明码也利用了奇偶校验位的概念，通过在数据位后面增加一些比特，可以验证数据的有效性。
Parity is an error-checking procedure in which the number of 1s must always be the same—either even or odd—for each group of bits that is transmitted without error.
奇偶校验是一个错误检查过程，其中每组无错传输位的1的数目必须始终相同，即或奇或偶。
The data packet increased checking parity can ensure data consistency in transmission, to remove and recover a reserved keyword of data though the positive replacement and reverse replacement.
增加数据包校验位，保证数据传输的一致性；通过正向替换和逆向替换消除并恢复数据中存在的保留关键字；
