Redundancy in computational architecture refers to the duplication of hardware or software components in a system in order to provide backup or failover capability. This redundancy can help ensure continuous operation and reliability, even in the event of component failures or disruptions. For example, a redundant power supply unit in a computer system can maintain power in case one fails, or redundant servers may be used to ensure uptime and prevent service disruptions. Redundancy can be costly and may require additional resources, but it is often necessary for critical systems where downtime is not acceptable.
