Question

Hamming distance is ______________________.

• A. A theoretical way of measuring errors
• B. A technique for assigning codes to a set of items known to occur with a given probability
• C. A technique for optimizing the intermediate code
• D. None of the above

Answer 1

The correct option is A A theoretical way of measuring errors

Hamming distance is a theoretical way of measuring errors.

A Hamming distance in information technology represents the number of points at which two corresponding pieces of data can be different. It is often used in various kinds of error correction or evaluation of contrasting strings or pieces of data.

The minimum Hamming distance is used to define some essential notions in coding theory, such as error detecting and error correcting codes. Thus a code with minimum Hamming distance d between its code words can detect at most d-1 errors and can correct ⌊(d-1)/2⌋errors.
