 Also known as domain name, a domain is the string of text that identifies a specific website, such as `google.com` or `facebook.com`. Every time you access a website from your web browser, a DNS query takes place and the DNS service maps the domain to the actual IP address where the website is [hosted](/fundamentals/setup/manage-domains/).
