Control Redundancy Check. Used to detect error in the transmission of data. The CRC is transmitted along with the data packets for comparison with a CRC calculated by the receiving device.
Cyclic Redundancy Code is a type of checksum. It's simple math, to see if a file has been changed. The idea is that if the total number of bytes within file changes that something inside the file must have changed, like a virus infecting and writing new code to the file. If a difference in a CRC check is found there may be a virus present in the file. Of course, CRC checks are not used in standard write and save operations, where the file size is expected to change.
Cyclical Redundancy Check - The mathematical calculation for checking the number of errors in a message.
an error detection scheme in which a number is derived from the data that will be transmitted. By recalculating the CRC at the remote end and comparing it to the value originally transmitted, the receiving node can detect errors.

CRC is a technique employed for error control in digital communications systems.
Cyclic redundancy checking is a method of checking for errors in data that has been transmitted on a communications link. A sending device applies a 16- or 32-bit polynomial to a block of data that is to be transmitted and appends the resulting cyclic redundancy code (CRC) to the block. The receiving end applies the same polynomial to the data and compares its result with the result appended by the sender. If they agree, the data has been received successfully. If not, the sender can be notified to resend the block of data.

Used to verify that data has been stored properly; it's used like a checksum, but is less prone to multiple-bit errors. During a transfer, both sides calculate the crc and compare the values, unless the --no-crc option is specified. Enstore uses a zero seededAdler 32 crc.
An error checking procedure in which bytes at the end of a frame are used by the receiving node to detect a transmission problem.
is the acronym for yclic edundancy heck. A procedure used in checking for errors in data transmission. CRC error checking uses a complex polynomial to generate a number based on the data transmitted. The sending device performs the calculation before transmission and sends its result to the receiving device. The receiving device repeats the same calculation after transmission. If both devices obtain the same result, it is assumed that the transmission was error-free. The procedure is known as a redundancy check because each transmission includes not only data but extra (redundant) error-checking values.
A final safety check of Eurofix message integrity.
A value computed from a sequence of octets (i.e., bytes) to detect errors that occur during data transmission. Typically, packet-switching network hardware computes a CRC (cyclic redundancy check) and appends it to a packet when transmitting. On a standard Ethernet LAN, this is known as the FCS (frame check sequence). Upon reception, the hardware verifies the contents of the packet by recomputing the CRC and comparing it to the CRC attached to the data it receives.
Cyclic Redundancy Check. An error checking method designed to improve the reliability of transmitted data.
Acronym for Cyclic Redundancy Check. The CRC is used to verify data block integrity. In a typical scheme, 2 CRC bytes are added to each user data block. The 2 bytes are computed from the user data, by digital logical chips. The mathematical model is made up of polynomials with binary coefficients. When reading back data, the CRC bytes are read and compared to new CRC bytes computed from the read back block to detect a read error. The read back error check process is mathematically equivalent to dividing the read block, including its CRC, by a binomial. If the division remainder is zero, the data is error free.
Cyclic Redundancy Check. An error-checking procedure for data transmission. The sending device performs a complex calculation, generating a number based upon the data being transmitted, and sends that number to the receiving device. The receiving device performs the same calculation after transmission. If the results match, the transmission succeeds. If the numbers don't match, it means the message was received in an altered state, and the data may be incorrect.

Cyclical Redundancy Check (CRC) is a procedure used to check for errors in data transmission.
A method of detecting errors in the serial transmission of data. A CRC for a block of data is calculated before it is sent, and is then sent along with the data. A new CRC is calculated on the received data. If the new CRC does not match the one that has been sent along with the data then an error has occurred.
Cyclic Redundancy Check (or, more rarely, Cyclic Redundancy Code), an efficient means of checking for accidental corruption of data. The most common version, including that used in PNG, is 32 bits (``CRC-32''), but 16-bit CRCs were common in older applications.
Cyclic Redundancy Check. Data stored or transmitted with data to detect corruption. By calculating the CRC data and comparing it to the original data sent, the receiver can detect some types of transmission errors.
Stands for Cyclic Redundancy Check. The CRC is used to verify the integrity of a data block. In a standard set-up, two CRC bytes are used for each user data block and they are computed from the user data by digital logic chips. Polynomials and binary coefficients make up the mathematical model of CRC bytes, which are read and compared to new CRC bytes from the read block whenever data is being read back to the system. Errors are detected by a mathematically equivalent division of the read block, (including its CRC), by a binominal and a result of zero means there are no errors.
This is an acronym for Cyclic Redundancy Check.
Cyclic Redundancy Check. A way of determining whether accidental transmission errors have occurred. Such algorithms are not cryptographically secure, in that attackers can often forge CRC values or even modify data maliciously in such a way that the CRC value does not change. Instead, one should use a strong, keyed message authentication code such as HMAC or OMAC. See Also: HMAC, Message Authentication Code, OMAC

Cyclic Redundancy Check. A check sequence that is designed to detect packet transmission errors. The size of the check sequence affects its ability to detect different types of errors and multiple errors.
Cyclic Redundancy Check. A method of checking for errors in data that has been transmitted on a communications link. The dividend polynomial is initially preset to 0, and the 1s and 0s of the data stream become the coefficients of the dividend polynomial. The division uses subtraction modulo 2 (no carries), and the remainder is transmitted as the error check field. The receiving station compares the transmitted remainder with its own computed remainder, and an equal condition indicates that no error has occurred. The polynomial value depends on the protocol and code set being used.
Cyclic Redundancy Code. A CRC is a type of checksum. A checksum algorithm takes a file (or other string of bytes) and calculates from it a few bytes (the checksum) that depend on the entire file. The idea is that, if anything in the file changes, the checksum will change. CRC checksums are usually used to detect random, uncorrelated changes in files.

Cyclic Redundancy Check: A technique for producing a string of bytes that represent the input file (the string is usually much smaller than the input file). The string of bytes are unique enough to be used to distinguish one file from another (and thus are useful for checking if the file changes as it would change the file's CRC value). Checksums and cryptographic hash algorithms are roughly equivalent to this.

This stands for "Cyclic Redundancy Code". The term "CRC" seems to be reserved for algorithms that are based on the "polynomial" division. The essential mathematical operation in the calculation of a CRC is binary division, and the remainder from the division determines the CRC. CRC's cannot, however, be safely relied upon to verify data integrity. CRC types are often identified by the polynomial, which is the number used as the divisor. A number of pages on this site make reference to the CRC used for different electronic Interface Buses.
( Cyclic Redundancy Check) Returns the number of blocks per second where CRC errors have been detected. This parameter varies between 0 and 75 blocks per second.
