The difference between Cohesion and Coupling is that cohesion is used intra-module and coupling is used inter-module. They are important aspects of software technology. Check out the key difference between Cohesion and Coupling in the table given below.

Difference Between Cohesion and Coupling
Although there are varied similarities between these two such as both are used for interconnecting two different parts in computer software. But there exist various differences between Cohesion and Coupling. The concept used for indicating the relationship inside the module or within the module is called cohesion. On the other hand, the concept used for indicating the relationship between two or more modules is known as coupling.
Cohesion vs Coupling
Developers decide whether the program needs high or low coupling/cohesion. Cohesion and coupling are methods of moduling. These two methods are used to create relationships with or within modules. Further, look into the basic difference between cohesion and coupling below:
Cohesion:
- It is also known as intra-module cohesion.
- It is used in intra-module.
- Coincidental cohesion, Logical cohesion, Temporal cohesion, Procedural cohesion, Communicational cohesion, Sequential cohesion, and Functional cohesion are the types of cohesion.
Coupling:
- It is also known as inter-module coupling.
- It is used in inter-module.
- Data coupling, Stamp coupling, Control coupling, and Common coupling are the types of coupling.
