Answer :
Final answer:
The hostname of the URL example.com is 'example'. The '.com' part of the URL is the top-level domain indicating a commercial entity. Understanding URLs is key for navigation and credibility assessment.
Explanation:
The question asks about identifying the host name within a given URL. In the URL example.com, the host name is 'example'. The domain name ending or top-level domain, in this case '.com', signifies the purpose or the nature of the website, such as commercial in the case of .com, educational for .edu, nonprofit for .org, government for .gov, military for .mil, and network-related for .net. The host name itself is the label that identifies a specific domain or machine on the Internet, while the top-level domain provides context for the website's function or sponsor.
Understanding the structure of URLs is critical for internet navigation and for evaluating the credibility of websites. Domain names are regulated by the Internet Corporation for Assigned Names and Numbers (ICANN) which ensures that each domain name is unique and facilitates global internet communication.
