Hierarchical architectures

Definition

Hierarchical architectures refer to systems structured in a layered manner, where components are organized at different levels of abstraction or functionality. This design allows for efficient processing and management of information, enabling complex tasks to be broken down into simpler sub-tasks. Such architectures play a crucial role in both cognitive functions and the integration of various subsystems within larger frameworks.
