汉明码，一个错误校验码码集。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。利用一个以上的校验位，汉明码不仅可以验证数据是否有效，还能在数据出错的情况下指明错误位置。 -Hamming code, a checksum error code set. 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. Use more than one parity bit, Hamming codes can not only verify the data is valid, but also in case of error in the data indicated the wrong location.
