In the context of software architecture, the common definitions often focus on the structural aspects of system design. Here’s how the chosen answers align with the iSAQB® guidelines on software architecture:

Building Blocks (B): A fundamental concept in software architecture, building blocks refer to the modular units from which the system is constructed. These can include modules, classes, or components, all of which are vital for defining the structure and behavior of the system.

Relationships (D): Relationships in software architecture define how different components or building blocks interact with each other. These interactions are essential for understanding data flow, dependencies, and communication patterns within the system.

Components (E): Components are larger than building blocks and encompass them, representing significant units of functionality within the system. Each component usually encapsulates a portion of the system ' s overall functionality and interacts with other components via interfaces.

Interfaces (G): Interfaces define the points of interaction between components or building blocks. They are critical for ensuring that components can function independently yet interact seamlessly when required.
