Which term describes any device connected to a network?

• A. Host
• B. A network node
• C. Switch
• D. VLAN

Answer: (B)

The main idea being tested is identifying a general term for any device connected to a network. A network node is any device that participates in the network by sending, receiving, or forwarding data. That includes computers (hosts), printers, servers, routers, switches—essentially any device that has a way to interact with the network. A host is a common type of end-user device, but not every device on a network is a host. A switch is a specific network device used to forward frames between segments, not a blanket term for all connected devices. VLAN is a logical grouping that partitions a network, not a device itself. So the broad, inclusive term that fits all connected devices is network node.
