Internal Block Diagram

An Internal Block Diagram (IBD) is a visual representation used in system engineering to show the internal structure of a system. It illustrates how different components or parts are interconnected and interact within the system, focusing on the internal organization rather than external interfaces. By mapping these relationships, an IBD helps engineers understand, analyze, and design complex systems more effectively, ensuring all parts work together as intended. It acts as a blueprint for internal structure, clarifying how the components fit and function internally.
