Effective communication checks should be applied to small as well as large IT configurations. IT hardware duplicity and echo checks are a way of establishing the accuracy achieved during the transfer of data over a communication medium. They provide quality checks and error-control techniques for data transferred over a computer network or other communications link.

IT operation duplication as an error control

In contrast to data deduplication, IT hardware duplicity checks utilize the principle of duplicate, or complimentary, processing to detect and correct errors. When this control is deployed, an operation is performed twice to assist in detecting errors. If the repeated operation matches the base operation, it is a duplicate operation. With this check, the result of the repeated operation is compared, and any difference between them will indicate a hardware-induced error requiring corrective action.
