In 3-5 sentences, describe the differences between fault tolerance and disaster recovery.(4 points)

Fault tolerance and disaster recovery are two distinct concepts in ensuring system resilience. Fault tolerance refers to a system's ability to continue functioning correctly even in the presence of hardware or software failures, typically achieved through redundancy and error detection mechanisms. In contrast, disaster recovery involves a strategic process for restoring IT infrastructure and operations after a significant disruptive event, such as natural disasters or cyberattacks, focusing on minimizing downtime and data loss. While fault tolerance emphasizes continuous operation, disaster recovery centers on recovery and restoration efforts post-incident.
