Definitions for "Hamming distance"
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.
