What is the function of a domain name?

A domain name serves primarily as a user-friendly address that helps people find a website on the internet. It simplifies access to online resources by converting numerical IP addresses, which are used by servers to identify each other, into human-readable names. For example, instead of typing a long string of numbers to reach a website, users can simply enter a domain name like www.example.com. This makes it easier for individuals to recall and share website addresses, enhancing overall navigation on the web.

While other options mention various components of web operations or online marketing strategies, none address the core function of a domain name as effectively. Hosting website data relates to servers and web hosting services, content management tools pertain to the systems used to create and manage digital content, and building a social media presence involves activities focused on social platforms rather than web address navigation. Hence, the primary role of a domain name in assisting users in locating a website is clearly illustrated by option C.
