   Hello,
   The Domain Name System (DNS) is a hierarchical naming system for computers, services, or any resource participating in the Internet. It associates various information with domain names assigned to such participants. Most importantly, it translates domain names meaningful to humans into the numerical (binary) identifiers associated with networking equipment for the purpose of locating and addressing these devices world-wide. An often used analogy to explain the Domain Name System is that it serves as the “phone book” for the Internet by translating human-friendly computer hostnames into IP addresses. For example, http://www.example.com translates to 208.77.188.166.
   A domain name server (or name server) is a computer that houses DNS zones of domain names. This includes A (host) records, CNAME (aliases) records, and MX (mail exchange) records for domain names. Name servers are essentially a piece of the Domain Name System.
   I hope this helps!

   system normally refers to the concept and the overall hierarchical mesh. A server is an individual server.
