What is the primary feature of a WAN (Wide Area Network)?

The primary feature of a Wide Area Network (WAN) is its ability to connect Local Area Networks (LANs) over large geographical distances. WANs facilitate communication and data transmission between different locations, which can be separated by extensive miles, making them essential for businesses, organizations, and internet service providers that need to connect multiple sites, branches, or users across cities, states, or even countries.

In contrast, the other options describe characteristics of different types of networks. The first option refers to a Local Area Network (LAN), which connects devices within a limited area such as an office or room. The third option also pertains to a LAN since it mentions covering a small geographical area, which is not applicable to WANs. Lastly, the fourth option about exclusive management by governmental bodies is incorrect, as WANs can be owned and managed by private companies as well as public entities, and they are not limited to a government-controlled infrastructure.
