The World Wide Web employs unique numbers referred to as IP addresses and each device or website that is part of the Web features such an address. It would be very hard to remember to visit 184.108.40.206 to open a website though, so a much simpler system was introduced in the eighties - domains. Every domain name contains a primary part and an extension, for example domain.com or domain.co.uk. A large number of extensions exist globally - part of them are assigned to countries, for example .co.uk in the abovementioned example, which is assigned to the United Kingdom, while various others are generic, for example .com or .net. Various extensions are available for registration by every entity and some others have particular requirements - company registration, regional presence, etc. You will be able to acquire a new domain via a registrar organization like ours and when the extension supports domain transfers, you'll be able to shift an existing domain name between registrars as well.
