Which term describes a network that spans a geographical area of more than 2 kilometers?

The term that describes a network spanning a geographical area of more than 2 kilometers is a Wide Area Network (WAN). WANs are designed to cover large distances, such as cities, countries, or even continents, and they connect multiple Local Area Networks (LANs) or individual devices across these extensive areas.

In contrast, Personal Area Networks (PANs) generally have a very limited range, typically within a few meters, connecting devices like phones and laptops. Local Area Networks (LANs) cover smaller areas, such as a building or a campus, usually within a range of up to a few kilometers. Home Area Networks (HANs) are specific types of LANs designed for use within a home, connecting personal devices within that residential space, which is also limited in range compared to a WAN.

Therefore, the defining characteristic of a WAN is its ability to connect devices that are spread out over a vast geographical area, making it the appropriate choice for this question.
