Which type of network is best suited for covering a campus or small geographical area?

The best choice for covering a campus or small geographical area is a Local Area Network (LAN). A LAN is specifically designed to connect computers and devices within a limited geographic area, such as a single building, a group of buildings, or a small campus.

LANs provide high data transfer rates and are typically used in environments where many devices need to be connected and communicate with each other quickly and efficiently, such as in schools, offices, or homes. They offer advantages such as lower costs for equipment and infrastructure, ease of installation, and low latency for data transmission.

In contrast, Wide Area Networks (WANs) cover much larger geographic areas and are used to connect multiple LANs over long distances, often requiring more complex equipment and infrastructure. Metropolitan Area Networks (MANs) serve areas larger than a LAN but smaller than a WAN, typically covering a city or a large campus, making them less suited for the specific smaller areas indicated in the question. Wireless Wide Area Networks (WWANs) provide coverage over larger distances through cellular networks, which is not ideal for campus or localized coverage where a wired LAN would be more efficient and practical.
