| Â | Redundancy check |
 | | The UPC barcode has a check digit computed by multiplying digits by alternately 3 and 1 and adding them up. | | | A check digit is a digit used as a redundancy check. | | | so the check digit, which is the 2 at the end, is correct. |

| | The check digit is always a single digit, and the number of digits in the first three groups is variable, though the full ISBN is always 10-digits. | | | Finally comes the check digit, a single-digit checksum that, according to the ISBN International Agency is “calculated on a modulus 11 with weights 10-2, using X in lieu of 10 where ten would occur as a check digit. | | | Each of the first nine digits of the ISBN-–excluding the check digit itself-–is multiplied by a number ranging from 10 to 2 and that the resulting sum of the products, plus the check digit, must be divisible by 11 without a remainder.” |

| Â | Hamming error correction is a method of 1-error correction |
| | Each column in the grid represents 1 binary digit of a binary number or word. | | | The trick to the dependency of each parity bit/column is that they are dependent on every bit/column that, when numbered in binary, has a 1 in the same digit as the number of the parity bit’s place. | | |            If the error bit was not the overall parity check bit, then all elements before xbit are appended to a list with one element, which is the opposite of the value in position xbit. |

| Â | Convert Decimal Number to Binary and Vice Versa |
| | If a computer is going to transmit a digit, it's much easier for the computer to check for errors in transmission if it has only two options. | | | In computers, each "bit" of information is like a place holder digit in a binary number. | | | Whatever digit is sitting in a particular place holder, you multiply that place holder amount (power of 10) by the digit, and then add them all up. |

| Â | Parity Checking - Simple Error Detection |
| | The sixteen digits in a credit card number contain extra information that is used, much like the extra digit in check numbers, to perform a calculation and verify that the number was entered correctly. | | | It should be noted that this approach that combines latitudinal and longitudinal parity checks works only when there is an even number of data bits per track. | | | Besides doing a parity check across the nine tracks, called a latitudinal parity check, an extra byte of information can be stored with a block of data. |
