34. Which type of network is used to connect wireless headphones to a smartphone?
Answer: A
Personal area network (PAN) is used to connect wireless headphones to a smartphone.
A personal area network (PAN) is specifically designed for short-range communication between devices, making it the ideal choice for connecting wireless headphones to a smartphone.
A) Personal area network (PAN)
This option is correct because a personal area network (PAN) facilitates communication between devices in close proximity, typically within a range of about 10 meters. Wireless headphones commonly utilize Bluetooth technology, which is a standard for PANs, allowing seamless connectivity with smartphones.
B) Wide area network (WAN)
A wide area network (WAN) connects devices over large geographical distances, often using leased telecommunication lines. This type of network is unsuitable for connecting wireless headphones to a smartphone, as the devices are intended for short-range communication, not extensive coverage.
C) Local area network (LAN)
A local area network (LAN) connects multiple devices within a limited area, such as a home, office, or building. While a LAN can support various devices, it is not the optimal choice for connecting wireless headphones to a smartphone, as PANs are specifically designed for such personal, close-range connections.
D) Extended area network (EAN)
An extended area network (EAN) is a less common term that generally refers to networks that cover larger areas than a LAN but are not as extensive as WANs. This type of network does not focus on the short-range communication required for connecting devices like wireless headphones and smartphones.
Conclusion
The use of a personal area network (PAN) is definitively correct for connecting wireless headphones to a smartphone due to its design for short-range device communication. All other options, including WAN, LAN, and EAN, fail to meet the specific requirements for this type of connection, which emphasizes proximity and ease of use.
