A domain is a special address that you can get through a registrar company. All the units that are linked to the Web, such as web servers, have numeric addresses, or IP addresses, which are very hard to remember, because of this the domain name system was launched as an easy means to recognize a given site on the Web. Thus, your site is available at www.domain.com as an alternative to 123.123.123.123, for example. A domain name possesses 2 parts - the Second-Level Domain, which is the actual web site name that you will be able to choose, and the Top-Level Domain, that is the extension - .com, .net, .org and so on. You'll be able to register your new domain through any type of registrar or transfer an active domain between registrars in a few simple steps. In the event that you choose to do the latter, your domain will be renewed instantly by the gaining registrar the moment the transfer process is 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 others will require local presence or a business license.
