In the URL https://codehs.com/hourofcode, what is the domain name?

The domain name in the URL https://codehs.com/hourofcode is codehs.com. A domain name is the part of the URL that specifies the primary address of a website. In this case, "codehs.com" is the unique identifier for the CodeHS website. It provides the means for users to find the site on the internet.

The other components of the URL serve different purposes. For example, "https" indicates the protocol used for secure communication, while "hourofcode" represents a specific path or resource within the main website’s structure. The option "www.codehs.com" includes a subdomain (www), which is not always necessary for a complete URL and is considered part of a broader domain name structure. Hence, codehs.com is the simplest and most accurate representation of the domain name.
