Impact of IT hardware failures on information integrity
Failure of a semiconductor, diode, or transistor may affect the electrical impulses utilized in the processing of data, the storage of data, and the communication of data between different equipment in the IT infrastructure. If the failure leads to a change in timing, strength, shape, or frequency of pluses; the result could be an invalid data operation, invalid data storage or transmission, or the modification or destruction of datum or program instructions.
The failure of a mechanical part is a hazard to the operation of peripheral input/output (I/O) and storage devices. Such a failure can result in an error in reading datum during an input operation or in an error in writing datum during an output operation.
