Which network is formed when you connect your mobile phone to another mobile phone using Bluetooth to transfer a MP3 song?

Correct option is B

When two mobile phones are connected using Bluetooth to transfer an MP3 song, the network formed is a PAN (Personal Area Network). A PAN is designed for short-range communication between personal devices, typically within a few meters. Bluetooth technology is a classic example of PAN usage, making it the correct choice in this scenario.
Important Key Points:
1. What is a PAN? A Personal Area Network connects personal devices within a very short range (usually up to 10 meters).
2. Bluetooth and PAN: Bluetooth is the most common technology used to create PANs between devices like smartphones, laptops, and earbuds.
3. Why PAN Fits This Case? The connection is between two nearby mobile phones, without any external infrastructure.
4. Common PAN Devices: Mobile phones, smartwatches, wireless headphones, and tablets.
5. Advantages of PAN: Low power consumption, easy setup, and secure short-range communication.
6. Real-Life Example: Transferring files, sharing internet via Bluetooth tethering, or connecting wireless accessories.
Knowledge Booster:
· Why option (a) LAN is incorrect? LAN covers a larger area like a room or building and typically uses Ethernet or Wi-Fi, not Bluetooth.
· Why option (c) WAN is incorrect? WAN spans large geographical areas such as cities or countries, unrelated to Bluetooth file transfer.
· Why option (d) MAN is incorrect? MAN covers a metropolitan area and is far larger than the Bluetooth range.
