1.	What is DNS? How does it operate on an internal network?
Answer» DNS stands for Domain Name System. It is the Internet's phone book. On the internet, humans access information by using domain names, such as scaler.com or interviewbit.com. Internet Protocol (IP) addresses are used by web browsers to interact with websites. A domain name is translated to an IP address (such as 152.178.1.1) by DNS, and the browser requests that IP address from the DNS server to make a connection and access the internet resources. In a nutshell, DNS is a network service that allows connections to be made to local or internet addresses using domain names rather than IP addresses.
