Quorum systems are a fundamental mechanism in distributed systems used to ensure consistency and coordination by requiring a subset of nodes to agree on a decision. They play a crucial role in fault tolerance, enabling systems to continue operating correctly even in the presence of failures by ensuring that any two quorums intersect and thus can detect conflicts.

Distributed systems consist of multiple interconnected components that communicate and coordinate their actions by passing messages to achieve a common goal. They offer scalability, fault tolerance, and resource sharing, but also introduce challenges such as network latency, data consistency, and system complexity.

Consistency refers to the steadfast adherence to the same principles or course of action over time, which fosters reliability and trust. It is essential in various fields, from personal habits to business practices, as it creates predictability and stability, allowing for the measurement of progress and effectiveness.

consistency

Coordination is the harmonious functioning of different elements or groups to achieve a common goal, requiring effective communication and the alignment of efforts. It is crucial in both individual tasks, where it involves motor skills, and in organizational contexts, where it involves strategic planning and resource management.

Fault tolerance is the ability of a system to continue operating properly in the event of the failure of some of its components. It is achieved through redundancy, error detection, and recovery mechanisms, ensuring system reliability and availability despite hardware or software faults.
