A domain is a user-friendly and unique web address that you're able to acquire for your web site. It maps a numeric IP address that is employed to identify websites and units on the Internet and it's much simpler to remember or distribute. Each domain name consists of two parts - the specific name that you select plus its extension. For instance, in domain.com, “domain” is known as Second-Level Domain and it's the element you're able to choose, while “.com” is the extension, that is called Top-Level Domain (TLD). You can purchase your domain name via any certified registrar organization or transfer an active one between registrars in case the extension can support this option. This kind of a transfer does not change the possession of a domain name; the only thing that changes is the place where you will be able to control the domain. The vast majority of the domain extensions are available for registration by any entity, but numerous country-code extensions have certain requirements like regional presence or an active company registration.
