Final answer:
A schematic diagram, also called a flow diagram, is a structured layout where different shapes represent different functions throughout a process with lines or arrows interconnecting those shapes indicating the path of flow for the process.
Step-by-step explanation:
A schematic diagram, also called a flow diagram, is a structured layout where different shapes represent different functions throughout a process with lines or arrows interconnecting those shapes indicating the path of flow for the process.
An example of a schematic diagram is a circuit diagram, which represents the connections and components in an electrical circuit.
Schematics are useful because they can represent a wide variety of situations and allow for the analysis of different scenarios using the same concepts and principles.
