A domain name is a text-based representation (in other words, a recognizable name) of the numerical address that computers use to locate each other on the Internet. In short, it's an easy way for people to remember where you are. It can also be the basis of your Web site marketing campaign.

"Domain name is ADDRESS or Easy name given for your pages and data on internet. E.g Address indersingh.com is a domain name which can be used for accessing files for this address and can be easily remembered."

A domain name is an identification label that defines a realm of administrative autonomy, authority, or control in the Internet, based on the Domain Name System (DNS).

Domain names are used in various networking contexts and application-specific naming and addressing purposes. They are organized in subordinate levels (subdomains) of the DNS root domain, which is nameless. The first-level set of domain names are the top-level domains (TLDs), including the generic top-level domains (gTLDs), such as the prominent domains com, net and org, and the country code top-level domains (ccTLDs). Below these top-level domains in the DNS hierarchy are the second-level and third-level domain names that are typically open for reservation by end-users that wish to connect local area networks to the Internet, run web sites, or create other publicly accessible Internet resources. The registration of these domain names is usually administered by domain name registrars who sell their services to the public.
