What does the term 'Domain Name' refer to in networking?

The physical location of a server
The name of the server that hosts the data
A type of network protocol
An identification for IP addresses

The correct answer is: The name of the server that hosts the data

A 'Domain Name' refers to the name assigned to a server that hosts specific data, facilitating user-friendly navigation on the internet. Domain names are part of the Domain Name System (DNS), which translates these easy-to-remember names (like www.example.com) into numerical IP addresses needed for locating and identifying computer systems on networks. Choosing a domain name as the basic identifier for an internet resource allows users to access websites without needing to remember complex numerical sequences. This naming system comprises various levels, such as top-level domains (e.g., .com, .org) and subdomains, enhancing the organization and usability of web resources. The other options do not accurately define what a domain name is. A domain name does not indicate the physical location of a server, nor does it represent a type of network protocol or serve as an identification for IP addresses in the same sense. Instead, it acts as a more user-friendly label that ultimately references an IP address in the background.
