Answer :
Final answer:
The two examples of relative domain names in the domain 'example.com' are incorrect as provided, since 'www.example.com' and 'mail.example.com' are fully qualified domain names including a subdomain, base domain, and a top-level domain (TLD). 'com.example.www' is formatted incorrectly, and 'example.com' is the base domain itself, not a relative name.
Explanation:
The question concerns relative domain names within a domain structure. A relative domain name is a name that doesn't include the top-level domain (TLD) and is relative to the base domain for a given context. In the domain 'example.com', which is a base domain, the two examples of relative domain names would be 'www' and 'mail', because they are subdomains of 'example.com'.
'www.example.com' is not a relative domain name; it is a fully qualified domain name that includes the subdomain 'www', the base domain 'example.com', and the TLD '.com'. Similarly, 'mail.example.com' is also a fully qualified domain name with 'mail' being a subdomain. 'com.example.www' is not a standard format for domain names as it reverses the typical order. On the other hand, 'example.com' is the base domain and not a relative domain name since it includes the TLD '.com'.
The TLD is the last segment of the domain name and can indicate the type of entity that operates the website, such as '.com' for commercial, '.edu' for educational institutions, and '.org' for organizations. The domain name endings such as '.com' are controlled by ICANN and serve as an important part of the URL structure, aiding in identifying and locating servers and resources on the Web.
