What are the two types of diagrams that provide complementary views of a block?

The two types of diagrams that provide complementary views of a block are the Internal Block Diagram (IBD) and the Block Definition Diagram (BDD).

The Block Definition Diagram offers a high-level overview of the system architecture, showing blocks and their relationships, properties, and hierarchies. It serves as a structural representation of the system, portraying how blocks interact and are organized.

In contrast, the Internal Block Diagram delves into the internal workings of a specific block, illustrating how parts of that block connect and communicate with one another. This diagram focuses on significant internal details, showing the interactions and interfaces between different components within the block.

Together, these diagrams offer a comprehensive understanding of both the structural and internal relationships of components within a system, highlighting how they fit together and interact while allowing for clear organization of complex systems design.

The other options, such as Use Case Diagrams, focus on functional aspects or behaviors of a system rather than providing complementary structural views of a block, making them less applicable in this context.
