Ethereum Name Service is an Ethereum-based decentralized naming system for cryptocurrency wallet addresses, content hashes, and metadata. ENS is the name and ticker symbol of the Ethereum Name Service's governance token.
The architecture of Ethereum Name Service consists of two smart contracts called the Registry and Resolvers. Registry is a single, smart contract that maintains a list of all domains and subdomains. The smart contract stores the domain owner's name, the domain's resolver, and the time-to-live of all records under the domain.
On the other hand, resolvers are smart contracts that map ENS domain names with their respective resources, such as cryptocurrency addresses and content hash. When you try to find an Ethereum address registered as an ENS name, such as bob.eth, the registry is asked which resolver is responsible for bob.eth. Then the query is sent to the resolver of bob.eth. The resolver then maps bob.eth with the associated Ethereum address.
