What is necessary for internet connection - wired or wireless?

• A. Network Settings
• B. Network ID
• C. Network Monitor
• D. Network Interface Card (NIC)

Answer: (D)

To connect to the internet, you need a way for your device to interface with a network. The component that provides that interface is the Network Interface Card. It handles the hardware side of the connection, turning the device’s data into signals the network can carry and vice versa. For a wired setup, this is an Ethernet NIC; for a wireless setup, it’s a wireless NIC (like Wi‑Fi). Without a NIC, the device cannot place or receive network traffic, so internet access isn’t possible regardless of other settings. Network settings, such as IP configuration or DNS, are important for proper communication, but they depend on having a NIC to send and receive traffic. A Network ID helps identify a network you join, and a Network Monitor is a tool for observing traffic; neither enables connectivity on its own. Modern devices often have built-in NICs, with wired or wireless capabilities, and can also use external adapters if needed.
