Definition
A Top-Level Domain (TLD) is the last segment of a domain name, positioned after the final dot (e.g., ".com," ".org," ".net"). TLDs are part of the Domain Name System (DNS) and are categorized into different types based on their purpose and origin.
Function
The primary function of a TLD is to help identify the nature of a website or its geographical origin. For example, generic TLDs, such as ".com" or ".org," can signify a variety of organizations or commercial entities, while country-code TLDs, like ".uk" or ".ca," indicate websites associated with specific countries. TLDs play a crucial role in web navigation, branding, and search engine optimization by influencing user perception and credibility of the domain in question.
