FIELD: information technologies.
SUBSTANCE: device to compare data in computer system comprises at least two actuator units and comparator, besides, data comparison is carried out in comparator, and each actuator unit processes input data and generates output data, at the same time actuator unit is arranged with the possibility to communicate to the comparator that it is not necessary to compare subsequent element of output data with element of output data, at least of the second actuator unit, afterwards, comparison of these at least two elements of output data takes place.
EFFECT: increased safety of computer system operation, using various actuator units and software.
