The World Wide Web uses unique numbers referred to as IP addresses and every single device or website that is part of the Web contains this kind of an address. It is pretty hard to remember to visit 123.123.123.123 to see a website though, that's why a much simpler system was created in the eighties - domains. Each and every domain name contains a primary part as well as an extension, for example domain.com or domain.co.uk. Many different extensions exist worldwide - some of them are given to countries, just like .co.uk in the abovementioned example, which is assigned to the United Kingdom, while many others are generic, like .com or .net. Some extensions are available for registration by any entity and some others have particular requirements - business registration, regional presence, etc. You will be able to get a new domain name from a registrar firm like ours and when the extension allows domain transfers, you'll be able to relocate an existing domain between registrars as well.
