The Domain Name System (DNS) is a distributed naming system that translates human-readable domain names (like example.com) into IP addresses used by machines to communicate over the internet.

Domain Name System (DNS) is the distributed naming system that translates human-readable domain names into IP addresses used by computers and networks.

Idempotency allows the same logical operation to be executed multiple times without producing additional side effects. Deduplication identifies repeated requests, commands, or events and prevents them from being processed as new work.

Distributed transactions coordinate one business operation across multiple services, databases, queues, or external systems. Unlike a local database transaction, no single transaction manager automatically guarantees that every participating component commits or rolls back together.

The CAP theorem describes a fundamental constraint in distributed data systems : during a network partition, a system cannot guarantee both strong consistency and full availability for every request.

Distributed systems often store the same data on multiple nodes to improve availability, fault tolerance, read scalability, and geographic performance . Replication introduces a difficult question: when one copy changes, how quickly must every other copy reflect that update?

A distributed system is a group of independent computers that communicate over a network and cooperate to provide one service. Applications use distributed architectures to handle more traffic, improve availability, process data closer to users, and continue operating when individual components fail
