A system configuration in which two independent computer systems perform identical processing simultaneously and cross-check each other's results to ensure reliability. Any discrepancy is detected immediately, making this approach suitable for high-reliability domains such as banking and aviation. It differs from a duplex system, which keeps a standby unit that takes over only upon failure.
