What internal device does a computer use to connect to a wired or a wireless network?

• A. Modem
• B. Switch
• C. Network Interface Card
• D. Hub

Answer: (C)

A computer connects to a network using a network interface card. This piece of hardware provides the actual link to the network medium, whether wired or wireless. A wired connection uses an Ethernet NIC with an RJ-45 port, while a wireless connection uses a Wi‑Fi adapter. The NIC handles framing, MAC addressing, and data transfer to and from the operating system, and can be built into the motherboard or added as a card or module. A modem, by contrast, links your local network to your Internet service provider rather than connecting to other devices on the LAN. A switch or hub is a separate network device used to connect multiple devices together, not an individual computer’s internal interface.
