data integrity
data integrity Resistance to alteration by system errors of data stored in a computer. It is a condition that denotes only authorized and proper alteration of data. It is a measure of the reliability of data read from magnetic media, in terms of the absence of undetected errors (see error rate). However the undetected error rate perceived by the host system may be worse than that arising at the magnetic disk or tape if undetected errors can arise, e.g. from the effect of noise on connecting cables where the interface concerned has insufficient error detection capability.
From a system point of view the undetected error rate of a peripheral may be inadequate: the system can improve on it by making additional provision for checking in software.
