What are some examples of fault tolerance in software?

Fault tolerance in software refers to the ability of a system to continue operating properly in the event of a failure. Examples include redundant systems, error detection and correction, and graceful degradation.

Can you explain how redundant systems work?

Sure! Redundant systems have multiple components that can take over if one fails. For instance, in a server setup, if one server goes down, another can immediately take its place, ensuring no downtime.

What is graceful degradation?

Graceful degradation is when a system continues to operate at a reduced level of functionality when part of it fails. For example, a web application might still allow users to access some features even if others are down.

Are there any real-world applications of these concepts?

Yes, many! For instance, cloud services like AWS use fault tolerance to ensure high availability, and banking systems implement redundancy to protect against data loss.
