In RapidMiner, operators are connected to each other through ____________.

• A. Pipes
• B. Edges
• C. Ports
• D. Bridges

Answer: (C)

Data flow between operators in RapidMiner happens via ports. Each operator exposes input ports and output ports, and you connect the output port of one operator to the input port of another to build a workflow. These ports are the connection points that carry data such as ExampleSets between operators, and the links between ports determine how data moves through the process. Some operators have multiple ports, enabling different data streams to be split or merged. Other terms like pipes, edges, or bridges aren’t used in RapidMiner to describe these connections; the appropriate term is ports.
