In comparing two bit patterns, the Hamming distance is the count of bits different in the two patterns. More generally, if two ordered lists of items are compared, the Hamming distance is the number of items that do not identically agree. This distance is applicable to encoded information, and is a particularly simple metric of comparison, often more useful than the city-block distance (the sum of absolute values of distances along the coordinate axes) or Euclidean distance (the square root of the sum of squares of the distances along the coordinate axes). also Metric.

What is the difference between Error detection and error correction?
In error detection we detect the error.but in error correction we can detect as well as coreect the error both.in error detection we use parity multiplication system i.e even and odd parity.and in error correction we use hamming code as a example.
Where does the expression hamming it up come from?
The expression "ham it up" refers to overacting or being excessively theatrical, and it is believed to have originated from vaudeville and early 20th-century theater performances. The term "ham" was used to describe actors who exaggerated their performances for comedic effect, often to the point of being ridiculous. The phrase likely derives from the notion of being a "ham" in the sense of someone who seeks attention through over-the-top antics.
Can parity be used to correct errors?
Yes, parity can be used to detect and correct errors, but it has limitations. A simple parity bit can identify if an error has occurred by checking if the number of 1s is odd or even, but it can only detect single-bit errors and cannot correct them. More sophisticated schemes, such as even and odd parity combinations or using multiple parity bits, can help correct certain types of errors, but they are still limited compared to more advanced error-correcting codes like Hamming code.
What are the error correcting methods?
Error correction methods are techniques used to identify and correct errors in data transmission and storage. Common methods include parity checks, where an additional bit is added to ensure the total number of 1s is even or odd; checksums, which involve summing data values to detect errors; and more advanced techniques such as Hamming codes and Reed-Solomon codes, which can both detect and correct multiple errors. These methods are essential in ensuring data integrity in various applications, from computer memory to telecommunications.

Whai is the difference between CRC and hamming code?
In CRC, the redundant bits are derived from binary division to the data unit. While in hamming code, the redundant bits are a function of length of the data bits.
How hamming codes works?
Hamming code is a linear error-correcting code named after its inventor, Richard Hamming. Hamming codes can detect and correct single-bit errors, and can detect (but not correct) double-bit errors. In other words, the Hamming distance between the transmitted and received code-words must be zero or one for reliable communication.
What is the minimum hamming distance if t-error correcting code?

Which approach jaccard or hamming distance is more similar to simple matching coefficient?
The answer is hamming. Check out this tutorial on SimilarityMeasurments: http://people.revoledu.com/kardi/tutorial/Similarity/index.html
Calculate hamming code between 1000110 and 1110100?
hamming code between 1000110 and 1110100 can be calculated by just exoring both codes with each other as follow: 1000110 1110100 ------------ 0110010 now by counting the ones in the result that gives 3 then hamming dictance = 3
In a viterbi algorithm the Add-compare-select unit calculates path metrics in that why you select smallest path metric as survivor path.?
The ACS computation compares the sampled symbol value with the values that would be expected for each possible transition on a noiseless channel. The metric is the distance (hamming distance for hard-decision, and euclidean distance for soft-decision decoders) from the actual symbol to an expected symbol, the smallest metric indicates the closest match.
