Redundancy:Redundancy refers to the duplication of critical components or resources in a system. It helps ensure uninterrupted operation by providing backups that can take over if primary components fail.
Error detection: Error detection is the process of identifying errors or faults in a system. Various techniques such as checksums or parity bits are used to detect errors and trigger appropriate recovery mechanisms.
High availability: High availability is a measure of how consistently and reliably a system can provide its services without interruptions or downtime. Fault-tolerant systems aim for high availability by minimizing disruptions caused by faults or failures.
