- Shared nothing MP. The processors share nothing (each has its own memory, caches, and disks), but they are interconnected.

What does it mean to write loosely coupled code?
Just try to understand things and how they fit into the big picture before you start typing code. Loosely coupled code means to apply SRP (Single Responsibility Principle) and to avoid using concrete types for things you feel they might change.
What can you do with a loosely coupled application?
When an application is loosely coupled, on the other hand, you can make changes to one part of an application without touching other parts of an application. For example, you can switch data access technologies without modifying your validation or controller logic.
What to do in iteration 4 of make the application loosely coupled?
Iteration #4 – Make the application loosely coupled. In this fourth iteration, we take advantage of several software design patterns to make it easier to maintain and modify the Contact Manager application. For example, we refactor our application to use the Repository pattern and the Dependency Injection pattern.
How to make a contact manager more loosely coupled?
In this fourth iteration of the Contact Manager application, we refactor the application to make the application more loosely coupled. When an application is loosely coupled, you can modify the code in one part of the application without needing to modify the code in other parts of the application.
