The World Wide Web employs unique numbers called IP addresses and each device or site that is part of the Web contains this kind of an address. It is very hard to remember to visit 18.104.22.168 to open a website though, because of this a much simpler structure was made in the 1980s - domains. Each domain name features a primary part and an extension, to give an example domain.com or domain.co.uk. A wide range of extensions exist globally - some of them are given to countries, like .co.uk in the aforementioned example, which is given to the United Kingdom, while various others are generic, for example .com or .net. Various extensions are available for registration by any kind of entity and some others have specific requirements - business registration, local presence, and so on. You are able to get a new domain from a registrar firm such as ours and when the extension supports domain transfers, you will be able to shift an existing domain between registrars as well.
