Fault-Tolerant Systems

Fault-tolerant systems are designed to continue functioning correctly even when parts of the system fail or encounter errors. They incorporate multiple layers of backup, error detection, and correction mechanisms to ensure continuous operation, minimizing downtime and preventing data loss. These systems are essential in environments like banking, healthcare, and aircraft control, where reliability is crucial. Essentially, fault-tolerance allows a system to "plan for failures" and adapt, maintaining performance and safety despite unexpected issues.
