Risk ManagementReducing data reliability and integrity risks from IT hardware
When properly deployed, parity bits can be utilized to detect communication errors between IT hardware items. An advantage of the double parity bit is that an error is defined in two dimensions:...

Risk ManagementHow electronically encoded bits become redundant
Generation of extra bits for a redundancy check is derived from the relevant data and, therefore, bears a logical relationship to the data. This logical relationship is only a control association and has no modifying effect on...
