Which type of network do we create when we connect two smartphones to transfer some photos through Bluetooth?

Correct option is A

The correct answer is PAN (Personal Area Network). When two smartphones are connected via Bluetooth to share data such as photos, files, or contacts, they form a Personal Area Network. PAN is a short-range network used to connect personal devices like smartphones, laptops, tablets, and wearable gadgets, typically within a few meters. It enables quick and secure communication between devices without using internet connectivity or cables.
Important Key Points:
1. PAN (Personal Area Network): Connects devices within a personal range (usually up to 10 meters) using technologies like Bluetooth or infrared.
2. LAN (Local Area Network): Covers a limited area like an office or school using wired or wireless connections.
3. MAN (Metropolitan Area Network): Connects multiple LANs within a city or large campus.
4. WAN (Wide Area Network): Connects multiple LANs/MANs across countries or continents (e.g., the Internet).
5. Application: PANs are used for wireless file sharing, tethering, and connecting peripheral devices.
Knowledge Booster:
· (a) PAN: Bluetooth, ZigBee and infrared technologies are examples of PAN implementations.
· (b) LAN: Used for internal communication and resource sharing (e.g., printers, servers) in organizations.
· (c) MAN: Extends over a larger area than LAN, often managed by ISPs or municipalities.
· (d) WAN: Covers vast geographical areas and enables global data exchange (e.g., the Internet).
· Bluetooth-based PANs operate under IEEE 802.15.1 standards and are energy-efficient for short-range data transfers.
