What does 'low in coupling and high in cohesion' mean

Question

I have problems understanding the statement low in coupling and high in cohesion. I have googled and read a lot about this, but still finding it hard to underst

Answer 1

Low Coupling and High Cohesion is a recommended phenomenon.

Coupling means to what extent various modules are interdependent and how the other modules are affected on changing some/considerable functionality of a module. Low coupling is emphasized as the dependency has to be maintained low so that very least/negligible changes are made to other modules.
