Fault Tolerance in Distributed Systems

Fault tolerance in distributed systems refers to the ability of a network of computers to continue functioning despite the failure of some of its components. When one part fails, the system automatically redistributes tasks to other working parts, ensuring that services remain available and data isn’t lost. This is crucial for activities like online banking and cloud services, where uninterrupted operation is essential. Fault tolerance is achieved through redundancy, error detection, and recovery mechanisms, allowing the system to handle unexpected problems while maintaining performance and reliability.
