A domain is a unique address that you're able to get from a registrar company. All units that are linked to the Web, such as web servers, possess numeric addresses, or IP addresses, which are rather hard to remember, so the domain name system was introduced as an easy way to distinguish a website on the World Wide Web. Using this method, your website is available at www.domain.com instead of 18.104.22.168, for instance. A domain name includes 2 separate parts - the Second-Level Domain, which is the actual web site name that you will be able to choose, plus the Top-Level Domain, which is the extension - .com, .net, .org and so on. You'll be able to register a new domain via any type of registrar or transfer an existing domain between registrars in just a few easy steps. Whenever you choose to do the latter, your domain name shall be renewed immediately by the gaining registrar as soon as the transfer process is completed. Along with the universal Top-Level Domains, there're country-code ones as well. Some of them can be registered by anybody, while others demand regional presence or even a business license.
