A domain is a distinctive address that you're able to buy from a registrar company. All of the devices that are linked to the World-Wide Web, including web servers, feature numeric addresses, or IP addresses, which are very hard to remember, for this reason the domain name system was introduced as an easy means to identify a site on the Internet. Thus, your web site can be reached at www.domain.com rather than 123.123.123.123, for example. A domain name has 2 different parts - the Second-Level Domain, that is the actual site name that you're able to pick, and the Top-Level Domain, that is the extension - .com, .net, .org and so on. You are able to register a new domain from any registrar or move an existing domain between registrars in a couple of simple steps. If you choose to do the latter, your domain name will be renewed automatically by the gaining registrar as soon as the transfer process has been carried out. Along with the universal Top-Level Domains, there're country-code ones as well. Some of them can be registered by anyone, while some others need regional presence or even a business license.
