Which term is an example of a server type?

• A. DNS server
• B. USB hub
• C. Printed manual
• D. Keyboard

Answer: (A)

A server is a system that provides services to other computers over a network. A DNS server fits this role because it stores domain name mappings and answers queries to translate domain names into IP addresses, enabling clients like web browsers and apps to reach the correct hosts. The remaining items are not servers: a USB hub is a peripheral device that expands USB connections; a printed manual is documentation; a keyboard is an input device. In short, a DNS server actively offers a network service, while the others are hardware or documents that don’t provide network services.
