Wide area network (WAN)

Explanation:

A local area network (LAN) refers to a group of personal computers (PCs) or terminals that are located within the same general area and connected by a common network cable (communication circuit), so that they can exchange information from one node of the network to another. A local area network (LAN) is typically used in small or limited areas such as a set of rooms, a single building, school, hospital, or a set of well-connected buildings. Some of the network devices or equipments used in a local area network (LAN) includes an access point, personal computers, a switch, a router, printer, etc.

On the other hand, a metropolitan area network (MAN) is formed by an aggregation of multiple local area network (LAN) that are interconnected using backbone provided by an internet service provider (ISP). A metropolitan area network (MAN) spans for about 5 kilometers to 50 kilometers in size.

Basically, a metropolitan area network (MAN) spans across a geographic area such as a city and it's larger than a local area network (LAN) but significantly smaller than a wide area network (WAN).

Wide area network (WAN) can be defined as a telecommunication network that covers a wide range of geographical locations such as countries or regions across the world for the purpose of communication and sharing information and data between different users.

Hence, a network that has locations in different countries is considered a wide area network (WAN).

Generally, wide area network (WAN) makes it possible for various organizations to interconnect with their branch offices, headquarters and other multiple locations across the globe. Wide area network (WAN) usually span over a distance of 50 kilometers.

Hence, the type of network used by the organization is most likely a Wide area network (WAN).
