Which statement about a domain name is accurate?

• A. It is a meaningful and easy-to-remember 'handle' for an Internet address.
• B. It is a numeric identifier assigned to a device.
• C. It is a protocol for transferring files.
• D. It is a hardware address.

Answer: (A)

Domain names are human-friendly handles for Internet addresses, designed to be easy to remember and type. They let people access websites without needing to memorize numerical IP addresses; a domain like example.com is mapped by the DNS to the actual numeric address computers use. That’s why this statement is accurate. The other descriptions refer to different concepts: a numeric identifier for a device is an IP address, not a domain name; a protocol for transferring files points to something like FTP, not a domain name; a hardware address refers to a MAC address, also not a domain name. In practice, domain names are what users type, and DNS translates them into IPs behind the scenes.
