Which network type would be used to connect computers across a region, like a city?

The most suitable choice for connecting computers across a region, such as a city, is a Metropolitan Area Network (MAN). A MAN covers a larger geographic area than a Local Area Network (LAN), which is typically limited to a single building or a group of nearby buildings, focusing on high-speed connectivity within a localized environment.

In contrast, a Wide Area Network (WAN) spans much larger areas, often encompassing cities, countries, or continents, and is utilized for connecting multiple LANs over long distances. Although a PAN is even smaller, designed for personal devices within a very short range, it is not applicable to city-wide connections.

Thus, a MAN effectively serves as a bridge for connecting various LANs and supports high-speed data exchange in urban areas, making it the appropriate choice for the scenario presented.
