Which term corresponds to a diagram that pictorially represents components and connections?

• A. Wiring Diagram
• B. Block Diagram
• C. Pictorial Diagram
• D. Process Diagram

Answer: (C)

Visual representations that show actual items and how they connect are captured best by a pictorial diagram. This approach uses pictures or icons to stand in for real components and draws lines or paths to indicate their connections, making it easy to see how things fit together in a physical layout. In contrast, a wiring diagram centers on electrical pathways and uses standardized symbols to map circuits, focusing on wires and connections rather than the physical appearance of components. A block diagram abstracts components into labeled blocks to illustrate functional relationships and data or signal flow at a high level, not the real-world layout. A process diagram outlines the sequence of steps in a workflow, emphasizing order and dependencies rather than the hardware connections. So the diagram that pictorially represents components and connections is the pictorial diagram.
