In geographic networks, what term refers to the point from which something originates?

• A. Origin
• B. Hub
• C. Source
• D. Node

Answer: (D)

In geographic networks, the point where a flow starts is represented as a node. A node is a specific location in the network—like a city, junction, or facility—that connects to edges (the routes or links). Flows of people, goods, or information originate at a node and move along edges to other nodes. While words like origin or source describe the starting point conceptually, the network framework centers on nodes as the concrete locations that serve as origins (and destinations) within the system.
