What do second-level domains typically represent?

Second-level domains typically represent human-readable names purchased by organizations. This is because second-level domains are the part of a domain name that appears directly to the left of the top-level domain (TLD). For example, in the domain "example.com," "example" is the second-level domain. Organizations use second-level domains to establish a unique online identity, making it easier for users to remember and access their websites. The second-level domain often reflects the name of the organization, its purpose, or attributes, which helps in branding and recognition.

Country-specific domains, generic top-level domains, and subdivisions of the root level refer to different aspects of the domain name system but do not accurately describe the role and function of second-level domains in the context of their recognition and purchase by organizations for unique identification.
