What is a domain name?

A domain name is fundamentally defined as a human-readable address used to access websites. It serves as a convenient way for users to navigate the internet without the need to remember complex numerical IP addresses. For instance, instead of typing a long string of numbers like "192.0.2.1" to reach a website, users can simply enter "example.com" into their web browsers. This simplifies web navigation for the general public, allowing for easier access to online resources and services.

The concept behind a domain name is essentially rooted in the need for user-friendly web addresses that correlate with specific IP resources. It not only allows for easier recall but also adds to the branding and identity of websites, making them more recognizable to users. While other options relate to various aspects of internet technologies, they do not accurately encapsulate the primary function and purpose of a domain name in the context of web browsing and overall internet navigation.
