What is the function of a NIC?

• A. Used to connect to a network via cable
• B. A device to store data
• C. A memory module
• D. A software firewall

Answer: (A)

A network interface card provides the hardware connection between a computer and a network, usually through an Ethernet cable. It acts as the network interface, allowing the computer to send and receive data over the local network by handling the physical signaling and data-link responsibilities, including using a unique MAC address. The NIC can be built into the motherboard or added as a card, and its main job is enabling network communication. It is not used for storing data, it is not a memory module, and it is not a software firewall.
