World of Computer Networking Your CCNA start - Responsibilities of Domain Name System (DNS) Servers

The video tutorial explains the four types of DNS servers: recursive DNS resolvers, root name servers, TLD name servers, and authoritative name servers. Each server type has specific roles in processing DNS queries. Recursive DNS resolvers handle client requests and cache data. Root name servers direct requests to TLD name servers, which manage information about authoritative name servers. Authoritative name servers store DNS records and resolve queries. The tutorial concludes by comparing the DNS registry to a library for better understanding.
