Final answer:
Hierarchical modular architecture is a design framework where systems are built using a series of nested sub-modules, commonly used in engineering and digital architecture to meet complex technical and functional requirements.
Step-by-step explanation:
The architecture that involves building systems composed of modules, which in turn are composed of sub-modules, and so on in a hierarchical manner is commonly referred to as modular architecture or hierarchical modular architecture. This approach can be seen in various forms of engineering and technology design, including computer systems, software engineering, and digital architecture. An example of this is the structured design of a new jet engine, specifying its structure and the materials from which it is built. Similarly, the development of design architecture in a building, from a concept to a detailed plan, incorporates this modular process. These layers of design are crucial for creating complex systems that meet both technical and functional requirements.
