Final answer:
The laptop's Bluetooth module refers to WPAN (Wireless Personal Area Network). Bluetooth is categorized under WPAN, which enables device interconnectivity in close proximity. WLAN and WWAN relate to wider network connectivity, and a riser card is used for motherboard expansion.
Step-by-step explanation:
The answer to the question 'Which of the answers listed below refers to a laptop's Bluetooth module? WWAN WLAN Riser card WPAN' is WPAN (Wireless Personal Area Network). Bluetooth technology falls under the category of WPAN, which is designed for interconnecting devices within a relatively small area, usually within a person's reach. In contrast, WLAN (Wireless Local Area Network) refers to wireless connectivity within a wider area, such as within a building or campus, and includes technologies like Wi-Fi. WWAN (Wireless Wide Area Network) pertains to cellular connectivity, enabling internet access over large areas such as cities or regions. A riser card is a circuit board that gives a computer motherboard the option for additional expansion cards to be mounted perpendicular to the motherboard.
