What is a key differentiator of a metropolitan area network (MAN)?

A metropolitan area network (MAN) is designed to cover a larger geographical area than a local area network (LAN) but is not as expansive as a wide area network (WAN). Typically, a MAN spans a city or a large campus, connecting various locations such as multiple buildings, schools, and sometimes even government offices within that urban setting.

The concept of a MAN is particularly useful for organizations or service providers that need to facilitate data transfer and communication services across a metropolitan-sized area more efficiently than what a LAN would allow. For instance, a university may use a MAN to connect its different departments or campuses situated within the same metropolitan area, enabling seamless access to shared resources and data.

In contrast, other choices pertain to either smaller coverage areas (like a single building or just campuses) or imply an extensive range not characteristic of a MAN (large geographical areas). Thus, the defining aspect of a MAN is its focus on providing connectivity across an entire urban area, which is why it is recognized for its broader coverage compared to other network types.
