Modular designor modularity in design, is a design principle that subdivides a system into smaller parts called modules (such as modular process skids), which can be independently created, modified, replaced, or exchanged with other modules or between different systems.
Modularityis the degree to which a system's components may be separated and recombined, often with the benefit of flexibility and variety in use.
Modularity (networks)is a measure of the structure of networks or graphs which measures the strength of division of a network into modules (also called groups, clusters or communities).
