A domain name is a unique name that is used to identify and locate a website on the internet. It is also called the website’s address or URL (Uniform Resource Locator). Domain names typically consist of two parts, the first being the name of the website, and the second being the domain extension, such as .com, .org, .edu, etc. Domain names are registered with domain name registrars and are used to direct internet traffic to a specific website or online service.
