A domain is a unique address that you are able to purchase via a registrar company. All units that are linked to the World-Wide Web, such as web servers, have numeric addresses, or IP addresses, which are very difficult to remember, because of this the domain name system was launched as an easy means to recognize a particular site on the Web. Using this method, your site is available at www.domain.com rather than 123.123.123.123, for example. Your domain name possesses 2 separate parts - the Second-Level Domain, which is the actual web site name that you're able to pick, as well as the Top-Level Domain, which is the extension - .com, .net, .org and so on. You will be able to register your new domain name via any sort of registrar or move an existing domain name between registrars in just a few easy steps. Whenever you decide to do the latter, your domain name will be renewed instantly by the gaining registrar right after the transfer process is completed. Along with the universal Top-Level Domains, there're country-code ones too. Some of them can be registered by anyone, while some others require regional presence or even a business license.
