What is a DNS server?

The abbreviation DNS stands for Domain Name System. DNS server helps in transforming the web address to the IP address for your web browser when it connects to the internet. 

The DNS server is a network of servers which is responsible for tracking alphanumeric names for browsers and internet-connected devices. It, thereby, matches them with the right numerical IP addresses. When the server is not responding, then this conversion cannot happen. This is why you cannot browse the internet easily when the DNS server stops responding even though your PC seems to be correctly configured.

DNS is a hierarchical tree data structure where the topmost portion consists of root name servers. There are two types of DNS; viz, public DNS and internal DNS.
