Which of the following is an example of a generic top-level domain (gTLD)?

  1. .us

  2. .com

  3. .ca

  4. .uk

The correct answer is: .com

A generic top-level domain (gTLD) is a category of top-level domains that are not tied to a specific country or geographic location. These domains are intended for general use and can be registered by anyone, regardless of their location. The correct answer, .com, is a prime example of a gTLD. Originally intended for commercial entities, it has since become one of the most widely recognized and used domains on the internet for various types of websites, including personal, educational, non-profit, and more. This broad use underscores its generic nature and how it transcends geographic boundaries. In contrast, the other options represent country code top-level domains (ccTLDs). The .us domain is specifically associated with the United States, .ca is exclusive to Canada, and .uk is reserved for the United Kingdom. These domains reflect geographical implications and limitations, distinguishing them from the global applicability of .com.
