What does a 'domain name' represent?

• A. A numerical IP address assigned to a website
• B. A human-readable address of a website
• C. A type of programming language for websites
• D. A security feature for websites

Answer: (B)

A domain name serves as a human-readable address for a website, making it easier for people to access online content without needing to remember numerical IP addresses, which are not intuitive. For example, instead of typing in a series of numbers like 192.0.2.1, users can simply enter "example.com" into a web browser. This convenience plays a crucial role in the functionality of the internet, as it streamlines navigation and enhances user experience.

The other options represent concepts that are not accurate descriptions of a domain name. An IP address is indeed a numerical identifier, but it does not embody the purpose of a domain name. A programming language refers to the set of instructions used to create web applications and sites, which is unrelated to domain names. Finally, while security features are essential for websites, they are separate from the concept of what a domain name is and its role in web addressing.
