| | Cyclic redundancy check - Wikipedia, the free encyclopedia |
| | A cyclic redundancy check (CRC) is a type of hash function used to produce a checksum, which is a small number of bits, from a large block of data, such as a packet of network traffic or a block of a computer file, in order to detect errors in transmission or storage. | | | A CRC is computed and appended before transmission or storage, and verified afterwards to confirm that no changes occurred. |

| | September 1990/Implementing The CCITT Cyclical Redundancy Check/Sidebar |
| | Parity checking is easily implemented in hardware and is a feature found on most data comm chips. | | | One of the simplest error detection schemes is parity checking. | | | The value of the parity bit depends on the number of 1 bits in the byte, and also on the type of parity checking used. |

| | Embedding a secondary communication channel transparently within a cyclic redundancy check (CRC) |
| | The cyclic redundancy check is based upon the division algorithm for the ring of polynomials with coefficients taken from an algebraic field. | | | Several techniques are proposed here for transparently recapturing a small portion of the capacity of a cyclic redundancy check (CRC) that is used to protect a data packet from transmission errors, and employing the recaptured capacity to carry a secondary communication channel. | | | When the receiver determines that an inbound packet does not check according to any of the generators, the receiver adds the various error patterns, again looking through the possibilities by constrained trial and error for the error pattern that was employed by the transmitter and the attendant secondary-channel word. |

| | cyclical redundancy check |
| | This procedure is known as a redundancy check because each transmission includes extra or redundant error-checking values as well as the data itself. | | | As a security check, a CRC may be used to compare the current size of an executable file against the original size to determine if the file has been tampered with or changed in some way. | | | The sending computer uses one of several formulas to calculate a value from the information contained in the data, and this value is appended to the message block before it is sent. |

| | cyclic redundancy check from FOLDOC |
| | The CRC is "redundant" in that it adds no information. | | | It is calculated using division either using shifts and exclusive ORs or table lookup (modulo 256 or 65536). | | | A single corrupted bit in the data will result in a one bit change in the calculated CRC but multiple corrupted bits may cancel each other out. |

| | Block Redundancy Check |
| | The longitudinal parity byte is created by placing individual bytes of a string in a two-dimensional array and performing a Vertical Redundancy Check vertically and horizontally on the array, creating an extra byte. | | | (LRC, Block Redundancy Check) An error checking method that generates a longitudinal parity byte from a specified string or block of bytes on a longitudinal track. | | | This is an improvement over the VRC because it will catch two errors in the individual characters of the string, beyond the odd errors. |

| | Cyclic Redundancy check - AATraders |
| | Cyclic Redundancy check is an error checking technique to determine if data has been randomly and accidentally changed while in transit from one location to another. | | | This error checking also occurs when data is sent to and from drives in an individual system, and the re-request for data is done by software, not observed by users. | | | This is often unseen to the receiver and sender of the data, because it is done via software. |

| | Method and apparatus for calculating the longitudinal redundancy check in a mixed stream channel - Patent 5706298 |
| | The method may further feature matching a determined logical redundancy check at the end of the data stream with a previously determined logical redundancy check for the data stream, for example, when the data stream is being delivered from storage to a host computer. | | | Accordingly, longitudinal redundancy checking in an intermixed environment, often ignored in previous systems, is implemented without need to "involve" any host CPU facilities unless there is an error. | | | Since the interim results of the longitudinal redundancy check calculation are maintained as part of the context, when the DMA operation continues a stream of data, at 60, the controller first checks to determine whether this is the beginning of a new block. |

| | VERTICAL REDUNDANCY CHECK - Definition |
| | (VRC) An error checking method performed on one 8-bit ASCII character, where the 8th bit is used as the parity bit. | | | This method is unreliable because if an odd number of bits are distorted, the check will not detect the error. | | | The resulting parity bit is constructed by XORing the word. |

| | Patent 4761782: Error correction of digital image data by means of image redundancy |
| | The original check bits attached to the data are compared to the re-encoded check bits to determine if the errors are correctable, and, if so, what steps must be taken to correct the errors and to restore the original redundancy to the recovered data. | | | The sample values of a digitized image are encoded utilizing the amount of redundancy in the digital data to generate check bits which are attached to blocks of the data prior to transmission or recording. | | | Upon recovery, either the check bits or the data may be recoverable without the other being in error because of the interleaving, and after the data and check bits have been properly reassembled, error correction may be accomplished. |
