The number of disagreeing bits between two binary vectors. This is used as a measure of dissimilarity.

The number of digits that are different between two numbers. The Hamming distance between the two binary numbers 110010 and 110100 is 2, since two of the binary digits are different.

A characteristic of any given data code that indicates the ability to detect single bit errors; it equals the number of bits in any given character that must be changed to produce another legitimate character.

The number of digit positions in which the corresponding digits of two binary words of the same length are different.

The number of bits which differ between two binary strings of equal length.

In information theory, the Hamming distance between two strings of equal length is the number of positions for which the corresponding symbols are different. Put another way, it measures the number of substitutions required to change one into the other, or the number of errors that transformed one string into the other.
