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 66.230.200.100). People 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.

DNS is short for Domain Name Service

DNS (Domain Name Services) is what your computer uses to convert names, such as "yahoo.com" into IP addresses. The only way to locate an object on a network (or the Internet) is by its IP address. Names like "yahoo.com" mean nothing to a network. So DNS is a table of domain names and their matching IP addresses. When you type in "yahoo.com", it is converted to something like 20.104.234.90 (or whatever yahoo's IP really is)
It also works in reverse that it can get an address, and tell you the domain name connected to that address.

DNS is mainly used to convert human meaningful names (domain name) to computer meaningful name (IP address) in Internet.
