Which of the following is an example of a top-level domain?

A top-level domain (TLD) refers to the last segment of a domain name, which appears following the final dot in an Internet address. The function of a TLD is to categorize domains based on different factors such as type or geographic location.

In the case of “.gov,” this is a specific type of top-level domain that is reserved for government entities in the United States. It is recognized globally as a domain representing official government web pages. TLDs like “.gov” serve not only to identify the nature of the organization that owns the domain but also help in establishing trustworthiness among users.

In contrast, "example," "network," and "country" do not represent TLDs. "Example" could refer to a sample domain, while "network" is often associated with second-level domains or could be part of a larger domain name but does not stand alone as a TLD. "Country" refers to a geographical region or entity rather than a domain classification itself. Each specific country has its own designated country code TLD (ccTLD), such as ".uk" for the United Kingdom or ".ca" for Canada, but "country" itself does not qualify as a top-level domain.
