Final answer:
The portion labeled ".com" in the URL is the top-level domain, which indicates the purpose or geographic location of the website.
Step-by-step explanation:
In the URL, the portion labeled ".com" is the top-level domain. A top-level domain (TLD) is the last part of a domain name and indicates the purpose or geographic location of the website. In this case, ".com" is a commonly used TLD for commercial websites.
Other examples of TLDs include ".org" for non-profit organizations, ".edu" for educational institutions, and ".gov" for government websites.
