Network Type Geographical Coverage Explained

The question asks to identify the network type that spans the largest geographical area among the given options: PAN, LAN, MAN, and WAN.

Understanding Network Scope

Network types are classified based on their geographical scope:

• PAN (Personal Area Network): Covers a very small area, typically within the range of a few meters around an individual (e.g., Bluetooth connecting a phone and headset).
• LAN (Local Area Network): Covers a limited geographical area, such as a single building, office, or home.
• MAN (Metropolitan Area Network): Spans a larger area than a LAN, typically covering a city or a large campus.
• WAN (Wide Area Network): Covers an extensive geographical area, potentially spanning across cities, countries, or even the entire globe. The Internet is the largest example of a WAN.

Identifying the Largest Area Network

Comparing the geographical scopes:

PAN < LAN < MAN < WAN

Therefore, a WAN covers the largest geographical area.
