A domain name is your online address on the internet.
All computers on the internet have a unique identifying number - an Internet Protocol address. Because this address is difficult to remember, we use a domain name.
A domain name is promoted so that customers can easily find your specific goods or services. Each website has its own distinct domain name, allowing it to be distinguishable from other sites. For the most part, domain names are easy to remember because they are usually made up of a business name and a commonly understood term or language that their customers will recognise.
