Which type of network encompasses a single geographic area, typically a campus?

The correct answer refers to a Local Area Network (LAN), which is specifically designed to cover a smaller geographic area such as a single building or a campus. A LAN allows multiple devices to communicate with each other and share resources like files and printers within a confined area, making it ideal for environments like schools, offices, and universities.

A Campus Area Network (CAN), while it may seem like a suitable choice because it also serves a specific geographical region, typically encompasses multiple LANs within a larger area, such as a college or corporate campus. It includes various interconnected LANs but is less commonly referred to than LAN for single locations.

In contrast, a Metropolitan Area Network (MAN) spans a larger geographical area, such as a city, connecting multiple LANs across multiple locations. A Wide Area Network (WAN) covers a much larger region and can connect entire cities, states, or even countries, making it unsuitable for the typical campus setting.

Thus, the definition and scope of a LAN is what distinguishes it as the correct answer for a network that operates within a single geographic area like a campus.
