A domain is a unique address that you are able to purchase via a registrar company. All units that are linked to the Internet, such as web servers, have numeric addresses, or IP addresses, which are quite difficult to remember, that's why the domain platform was created as an easy way to distinguish some site on the Internet. Using this method, your site can be reached at www.domain.com in place of 188.8.131.52, for example. Your domain name has 2 separate parts - the Second-Level Domain, that is the actual web site name that you can pick, as well as the Top-Level Domain, that is the extension - .com, .net, .org and so on. You will be able to register your new domain name via any kind of registrar or transfer a current domain name between registrars in a few simple steps. If you choose to do the latter, your domain shall be renewed immediately by the gaining registrar the moment the transfer process is completed. Along with the generic Top-Level Domains, there're country-code ones as well. Many of them can be registered by anybody, while others need regional presence or a business license.
