If a network spans a large geographic area, what is it commonly referred to as?

Correct option is B

A Wide Area Network (WAN) is a type of network that covers large geographical areas, often connecting multiple smaller networks like LANs (Local Area Networks). The internet is the most notable example of a WAN.
Important Key Points:
1. WANs are used for interconnecting offices, cities, or even countries.
2. Technologies like MPLS, leased lines, and satellite links enable WAN connectivity.
3. They operate on the network layer of the OSI model.
Knowledge Booster:
· Metropolitan Area Network (MAN): Covers a city or campus, smaller than a WAN.
· Storage Area Network (SAN): Dedicated to providing block-level storage to servers.
· Personal Area Network (PAN): Connects devices within a small range, such as Bluetooth.
