What Are the functions of DNS servers?

Answer 1

A Domain Name Server is a standard technology for managing the names of Web sites and other internet domains. DNS technology allows you to type names into your Web browser like compnetworking.about.com and your computer to automatically find that address on the Internet. A key element of the DNS is a worldwide collection of DNS servers.
