Which item is a network interface card used to connect a device to a network?

• A. Cable
• B. NIC
• C. Modem
• D. Router

Answer: (B)

A network interface card is the component that serves as the device’s actual interface to the network. It provides the physical port and the hardware functions needed for sending and receiving data over the network medium, and it may be wired or wireless. Even when a NIC is integrated into the motherboard, its role remains the same: it’s the point where the device connects to the network and interacts with other devices. A cable, by contrast, is just the conduit that carries signals between devices; it’s important, but it isn’t the device’s interface itself. A modem connects the local network to the Internet service provider and translates signals for that outside link, not the device’s interior network connection. A router directs traffic between different networks and can share a connection among multiple devices, but it isn’t the single device’s own interface to the network.
