What is the difference between coupling and cohesion?

Can you explain the difference between coupling and cohesion in software design?

Sure! Coupling refers to how closely connected different modules or components are, while cohesion refers to how closely related the functions within a single module are.

Why is it important to have low coupling and high cohesion?

Low coupling allows for easier maintenance and flexibility, while high cohesion ensures that a module is focused and easier to understand.

Can you give an example of high cohesion?

Certainly! A class that handles all user authentication tasks, like login, logout, and password reset, demonstrates high cohesion.

What are some common practices to achieve low coupling?

Using interfaces, dependency injection, and designing modules to be independent can help achieve low coupling.
