What are the key principles of fault tolerance?

Fault tolerance is the ability of a system to continue operating in the event of a failure. Key principles include redundancy, isolation, and graceful degradation.

Can you explain redundancy in more detail?

Redundancy involves having multiple components that can perform the same function. If one fails, others can take over, ensuring system reliability.

What does graceful degradation mean?

Graceful degradation refers to a system's ability to maintain limited functionality even when some components fail, rather than completely shutting down.

How does isolation contribute to fault tolerance?

Isolation prevents failures in one part of the system from affecting others. By containing faults, the overall system remains operational.

Are there any real-world examples of fault tolerance?

Yes, examples include cloud computing services that replicate data across multiple servers and aircraft systems designed to operate safely even with component failures.
