What is purpose of DNS server?

Answer 1

it assigns a name ( ip adress) to your device

Answer 2

A DNS(Domain Name) Server is kinda like a phone book for your computer. Just like you have a phone number, most people wouldn't know you by that number, they would have to look it up in a phone book. When you have a domain name, you must store your information on a computer. Each computer on the internet has an IP address which is a series of numbers. When someone types your web address in, the computer first goes to a DNS server to find the IP address associated with it, then it can go to that computer to pull up the website.

Hope that helps,
if you need to know in more technical terms let me know.

Answer 3

The domain name system (DNS) stores and associates many types of information with domain names, but most importantly, it translates domain names (computer hostnames) to IP addresses. It also lists mail exchange servers accepting e-mail for each domain. In providing a worldwide keyword-based redirection service, DNS is an essential component of contemporary Internet use.

Useful for several reasons, the DNS pre-eminently makes it possible to attach easy-to-remember domain names (such as "wikipedia.org") to hard-to-remember IP addresses (such as 207.142.131.206). Humans take advantage of this when they recite URLs and e-mail addresses. In a subsidiary function, the domain name system makes it possible for people to assign authoritative names without needing to communicate with a central registrar each time.
