Cohesion and Decoupling, what do they represent?

Question

What are Cohesion and Decoupling? I found information about coupling but not about decoupling.

Answer 1

decoupling allows the separation of object interaction from classes and inheritance into distinct layers of abstraction used to polymorphic-ally decouple the encapsulation which is the practice of using re-usable code to prevent discrete code modules from interacting with each other.
