A process for determining accuracy.

1. A bit, such as a parity bit, derived from and appended to a bit string for later use in error detection and possibly error correction.
2. A data bit associated with a character or block for the purpose of checking the absence of error within the character or block. [T1.226-1992]

A character, derived from and appended to a data item, for later use in error detection and possibly error correction.

A digit, derived from and appended to a data item, for later use in error detection and possibly error correction.

A device that is attached to interconnect the Go and Return paths of a circuit at the incoming end of a circuit on command to permit maintenance personnel to make a continuity check on a loop basis. [T1.110-1987]

A 16-bit sequence in the last two octets of a frame (excluding flags) that offers a cyclic redundancy check (CRC). The CRC is derived over either the header in unnumbered-information-header format frames or over the entire packet frame for unnumbered-information frames (excluding flags). The algorithm used is described in ISO
330
9. [T1.312-1991]

Cipher text generated by cryptographic logic to detect failures in cryptography. [INFOSEC-99]

An element in a Web page's interactive form that allows users to select an option associated with that element.
Note: The selection is sent electronically to the Web site when the user submits the form. [After Bahorsky]

Machine instructions used in the detection or interpretation of certain data or data fields from a diskette, for the purpose of determining whether the diskette is an authorized or unauthorized copy. [2382-pt.8]

1. The sum of a group of data items, which sum is used for checking purposes.
Note 1: A checksum is stored or transmitted with the group of data items.
Note 2: The checksum is calculated by treating the data items as numeric values.
Note 3: Checksums are used in error detecting and correcting.
2. [The] value computed on data… (Read More →)
