正解:A
A Personal Area Network (PAN) is designed to connect devices in close proximity, typically within a few meters, often using wireless technologies like Bluetooth. This allows for the interconnection of smart devices such as smartphones, tablets, and wearables within an individual's personal space. Unlike a Local Area Network (LAN), which covers a larger geographical area such as a home or office building and can support wired and wireless connections, a PAN specifically facilitates wireless connections between personal devices.
