Which type of network is known to be the smallest?

The correct choice is the type of network known as LAN, or Local Area Network. A LAN is designed to connect computers and devices within a limited geographical area, such as a home, school, or office building. Because of its localized nature, it typically consists of just a few devices over a short distance, making it the smallest type of network compared to others.

Wide Area Networks (WAN) cover large geographical areas, often spanning cities, countries, or even continents, while Metropolitan Area Networks (MAN) serve a larger area than a LAN but are still confined to a single metropolitan region. Campus Area Networks (CAN) connect multiple LANs across a limited area, typically a university campus or similar setup. Since LANs operate in the most confined spaces and have the fewest connected devices, they are recognized as the smallest type of network among the options provided.
