    2021-4-24 · In this post, we will understand the difference between cohesion and coupling −. Cohesion. It is an intra module concept. It represents relationships within the module. Increased cohesion is considered to be good for the software. It represents the functional strength of the modules. When modules are highly cohesive, a high quality software is built. In cohesion, module focuses on the single thing. Coupling
