Final answer:
A network is the correct term for the set of links or routes between places and the places themselves, integral to urban planning and geography.
Step-by-step explanation:
A network is the set of links or routes between places and the places themselves. When we think about functional regions, these involve a centralized node or a point of control for an organized system which has various subsidiary locations connected to it, such as a network of radio stations broadcasting the same content. This idea is aligned with the Central Place Theory, which also concerns the organization of spaces and places in relation to goods and services within larger urban systems. Networks are integral to understanding the morphology of cities as they provide insights into the spatial structure and organization influencing various cultural, social, and political aspects of urban life.
