Which component is responsible for connecting a computer to a network?

• A. CPU
• B. NIC
• C. RAM
• D. SSD

Answer: (B)

Connecting a computer to a network is handled by the network interface component. The network interface card provides the actual hardware link to the network, whether through a wired Ethernet port or a wireless adapter. It handles sending and receiving data frames, manages the physical connection, and provides the unique MAC address that identifies the device on the network. Without this interface, the computer can’t place or receive network signals. The CPU is the brain that processes instructions, RAM is temporary workspace for active data, and the SSD stores data long-term. None of these directly enable the computer to connect to a network, which is why the network interface card is the correct component for network connectivity.
