Which of these is an example of a top-level domain?
- www.
- .org
- https://
- All of the above
Explanation: The correct answer is: .org. A top-level domain (TLD) is the highest level in the hierarchical Domain Name System (DNS) of the internet. It appears at the end of a website’s domain name and typically represents the type or purpose of the website. Common examples of TLDs include ‘.com’, ‘.org’, ‘.net’, ‘.edu’, and ‘.gov’. In the given options, ‘.org’ is the only example that represents a TLD. ‘.org’ is commonly associated with organizations, non-profits, and other entities, signifying their nonprofit or non-commercial status. The other options provided— ‘www.’ and ‘https://’—are not TLDs but rather prefixes or protocols used in URLs. ‘www.’ is a subdomain used to designate the World Wide Web portion of a website, while ‘https://’ is a protocol indicating a secure connection. Therefore, ‘.org’ is the correct example of a top-level domain in this context.
