Modularity

Definition

Modularity is the concept of breaking down complex systems into smaller, manageable, and interchangeable components or modules. This approach allows for easier manipulation, understanding, and redesign of biological systems, making it a key principle in both bioengineering and systems analysis. By utilizing modular designs, researchers can create standardized parts that can be combined in various ways to produce desired functions or outcomes.
