A business has four locations throughout a city and needs to set up a network to share information among these locations. Which computer network should be used?

A WAN spans large geographical areas, typically connecting networks across cities, countries, or even continents. While it could theoretically connect the business locations, it is not optimized for communication within a single city. Using a WAN would lead to unnecessary complexity and costs when a more localized solution is available.

A LAN is intended for a limited area, such as a single building or a small group of nearby buildings. Since the business has four distinct locations throughout the city, a LAN would be insufficient to connect all sites effectively. It does not provide the necessary range to cover multiple, dispersed locations.

A CAN typically serves a collection of buildings within a campus-like environment, such as a university or business complex. While it could connect multiple buildings, it is not designed for separate locations throughout a city. This makes it less suitable for the intended purpose of linking diverse business sites.
