Understanding Domain Names

What are the different levels of domains in a domain name?

a. root, com, example, www
b. com, www, example, root
c. root, com, example, www
d. example, root, www, com

Answer:

The root domain is implied, 'com' is the top-level domain, 'example' is the second-level domain, and 'www' is the third-level domain. The correct order is root, com, example, www which is option c.

In the domain name system, the root domain is implied and not directly visible in the web address. The top-level domain (TLD) is the part of the domain name located to the right of the dot ('.'). Common examples of top-level domains include .com, .org, and .edu. The second-level domain is directly to the left of the TLD and often represents the name of the individual, organization, or company associated with the address. The third-level domain, or subdomain, often includes 'www' but can be other prefixes as well. In the example provided, 'www' would be the third-level domain, 'example' would be the second-level domain, and 'com' would be the top-level domain. The root is always present but not displayed, and in choice options, when it is listed, it is often denoted as an empty string or a dot. For the conceptual question presented here, the correct structure, with the provided options, would be 'root, com, example, www' making 'c' the correct answer.
