Explanation: 

Detailed explanation-1: -The domain name system (DNS) is a naming database in which internet domain names are located and translated into Internet Protocol (IP) addresses. The domain name system maps the name people use to locate a website to the IP address that a computer uses to locate that website.

Detailed explanation-2: -The DNS has three components: authoritative servers, recursive servers, and clients (resolvers). A client (resolver) is installed in any computer with TCP/IP software. Generally speaking, a client is any computer with Internet access capability.

Detailed explanation-3: -DNS is the address book of the internet, which performs a simple function of translating domains to IP addresses. One way of looking at it is that it’s a distributed read-heavy database with caches on top.
