Which term describes the interconnection of LANs within a city?

The term that describes the interconnection of LANs within a city is "Metropolitan Area Network" or MAN. A MAN typically covers a larger geographic area than a Local Area Network (LAN), which is limited to a small area such as a building or a campus. However, it is smaller than a Wide Area Network (WAN), which spans across larger distances, such as multiple cities or countries.

In the context of networking, a MAN connects various LANs in a particular metropolitan area, allowing for efficient data exchange and communication within that urban region. This type of network is particularly useful for businesses and organizations that need to connect multiple locations within a city, offering better performance and lower latency compared to a WAN.

Global Area Network (GAN), while also a network type, refers to connecting networks across the globe, which is broader than what a MAN covers. Therefore, the term "Metropolitan Area Network" accurately captures the concept of LAN interconnections within a specific city.
