Final answer:
A system flowchart is used to illustrate the flow of data among different areas within an organization, providing an overview of data interactions.
Step-by-step explanation:
The flowchart that illustrates the flow of data among areas of responsibility in an organization is known as a system flowchart. A system flowchart represents the flow of data between different components or areas within a system or organization. It helps to visualize the movement of data and processes, showing how data is input, processed, and output within the system.
Unlike program flowcharts, which depict the sequence of operations in a program, or document flow charts which show the flow of documents and data among areas of responsibility within an organization, a system flowchart focuses on the general flow of operations. It outlines how data moves through various systems and processes within the organization, providing a high-level overview of these interactions.
