What is meant by 'Domain Name' in networking?

A 'Domain Name' refers specifically to a name that identifies a network domain, providing a human-readable address for accessing resources available on the internet. It serves as a unique identifier that simplifies the process of referencing websites and other online services. Instead of using a numerical IP address, which can be difficult to remember, a domain name allows users to navigate the internet more intuitively.

For instance, when you enter “www.example.com” into a web browser, the domain name system (DNS) translates that into an IP address that is used to locate the server hosting the website. This naming system is essential for organizing and managing the internet's vast resources, enabling users to connect to specific domains effectively.

The other choices don't encapsulate the full meaning of "Domain Name." A unique identifier for servers could apply more broadly to various naming conventions and IP addresses; a protocol for network communication refers to the rules governing data transmission and does not define a domain name; and an address for routing internet traffic is more aligned with IP addresses than with the concept of a domain name. Thus, the most accurate description of a domain name within networking is that it identifies a specific network domain.
