How do DNS resolvers help in resolving domain names?

DNS resolvers play a crucial role in resolving domain names by acting as a bridge between a user's device and the domain name server. When a user enters a domain name into their web browser, the resolver first checks its cache to see if it already has the corresponding IP address stored. If not, the resolver then queries a series of DNS servers to find the correct IP address for that domain. Once the IP address is found, the resolver caches it for future use, speeding up the process for subsequent requests to the same domain. Overall, DNS resolvers are essential in translating human-readable domain names into machine-readable IP addresses, allowing seamless connectivity on the internet.
