Question 8

Personal area network (PAN) is used to connect wireless headphones to a smartphone.

Personal area networks (PANs) are specifically designed for short-range communication between personal devices, such as connecting wireless headphones to a smartphone. This type of network allows devices to communicate within a small radius, typically around 10 meters.

A) Extended area network (EAN)

Extended area networks are designed to cover larger geographical areas than traditional networks, typically linking multiple local area networks. However, they are not suitable for connecting personal devices like headphones to smartphones, as their range and complexity exceed what is needed for such connections.

B) Personal area network (PAN)

Personal area networks are ideal for connecting devices such as smartphones to wireless headphones due to their focus on short-range communication. They facilitate easy and efficient connections between personal devices, making this the correct choice.

C) Wide area network (WAN)

Wide area networks cover large geographical areas and connect multiple local networks over vast distances. This type of network is not appropriate for connecting personal devices in close proximity, such as headphones to a smartphone.

D) Local area network (LAN)

Local area networks are used to connect devices within a limited area, such as a home or office. While they could connect multiple devices, they are typically not utilized for direct connections like those between headphones and a smartphone, which are better served by PANs.

Conclusion

The correct answer, personal area network (PAN), effectively describes the type of network that allows wireless headphones to connect to a smartphone due to its short-range capabilities. All other options, such as EAN, WAN, and LAN, either cover larger areas or serve different networking purposes, making them unsuitable for this specific connection.
