Error detection or correction of the data by redundancy in hardware

Introduced: January 1980

Full Title

Full titles differ between systems:

IPC:

Error detection; Error correction; Monitoring > Responding to the occurrence of a fault, e.g. fault tolerance > Error detection or correction of the data by redundancy in hardware

CPC:

Error detection; Error correction; Monitoring (error detection, correction or monitoring in information storage based on relative movement between record carrier and transducer G11B20/18; monitoring, i.e. supervising the progress of recording or reproducing G11B27/36; in static stores G11C29/00) > Responding to the occurrence of a fault, e.g. fault tolerance > Error detection or correction of the data by redundancy in hardware

CPC subdivides this area 5x more granularly than IPC with 7 additional codes.

7 codes are CPC-only extensions.

1 shared codes have differing titles between IPC and CPC.

IPC defines codes here since 1980.
