The World Wide Web uses unique numbers called IP addresses and each unit or website that is a part of the Web features such an address. It would be very difficult to remember to visit 18.104.22.168 to see a website though, because of this a much simpler system was introduced in the 1980s - domains. Each and every domain contains a primary part and an extension, for instance domain.com or domain.co.uk. A number of extensions exist globally - part of them are assigned to countries, such as .co.uk in the aforementioned example, which is assigned to the United Kingdom, while others are generic, for instance .com or .net. Some extensions are available for registration by any entity and others have specific requirements - company registration, local presence, etc. You're able to obtain a new domain from a registrar firm like ours and if the extension supports domain transfers, you will be able to shift an existing domain between registrars too.
