Distributed consensus is a fundamental challenge in distributed systems, where multiple nodes must agree on a single data value to ensure consistency and reliability. It is crucial for the operation of distributed databases, blockchain technologies, and fault-tolerant systems, often employing algorithms like Paxos and Raft to achieve agreement despite potential failures and network partitions.

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.

Distributed databases store data across multiple physical locations to improve data availability, reliability, and performance. They enable concurrent data access and processing, but require complex mechanisms for data consistency, replication, and coordination among distributed nodes.

Network partitions occur when a network is divided into two or more segments that cannot communicate with each other, often due to failures in network infrastructure. This can lead to challenges in distributed systems, where maintaining data consistency and availability becomes difficult during such partitions.
