The World Wide Web uses unique numbers referred to as IP addresses and every device or website that is a part of the Web features this type of an address. It would be very hard to remember to visit 123.123.123.123 to open a website though, that's why a much easier system was introduced in the 1980s - domains. Each and every domain contains a primary part as well as an extension, to give an example domain.com or domain.co.uk. A plethora of extensions exist worldwide - part of them are assigned to countries, like .co.uk in the abovementioned example, which is given to the United Kingdom, while others are generic, for example .com or .net. Some extensions are available for registration by every entity and others have particular requirements - business registration, local presence, etc. You are able to obtain a brand new domain from a registrar company like ours and if the extension allows transfers, you'll be able to transfer an existing domain between registrars too.
