Question: 1 / 690

Which component is essential for enabling Wi-Fi capabilities in a laptop?

Ethernet port

Wireless Network Card

The wireless network card is crucial for enabling Wi-Fi capabilities in a laptop because it allows the device to connect to wireless networks. This component contains the necessary hardware and software to communicate with wireless routers and access points, facilitating the wireless transmission of data. Wi-Fi networks operate based on specific protocols, such as IEEE 802.11, which a wireless network card is designed to support. Without this component, a laptop would lack the ability to establish a wireless connection, effectively preventing it from accessing the internet or local networks wirelessly.

While the other components mentioned serve specific functions—like the Ethernet port for wired connections, the USB hub for peripheral connections, and the HDMI port for video output—they do not influence or support Wi-Fi functionality. Thus, the wireless network card is the only correct choice for enabling wireless networking in a laptop.
