Explanation
Correct answer: B) WLAN (Wireless Local Area Network).
A WLAN expansion card allows communication over 802.11 networks, which are wireless networks based on the Wi-Fi standard. These cards enable devices to connect to wireless networks, allowing communication without physical cables.
Here’s why the other options are incorrect:
-
Riser card: A riser card is used to extend the number of expansion slots in a computer, typically for devices like graphics or sound cards, but it is not related to wireless communication.
-
WPAN (Wireless Personal Area Network): WPAN refers to short-range wireless communication (e.g., Bluetooth), not 802.11 networks, which are used for WLANs.
-
WWAN (Wireless Wide Area Network): WWAN refers to wireless communication over large areas, typically via cellular networks (e.g., 4G or 5G), not 802.11 Wi-Fi networks.
