Thread: Newb question: Could someone please explain Object-Oriented design in laymens?

Hello. I'm pretty new here and was just wondering if someone could please explain what Object-Oriented design is in very simple terms.

Also if you can, based on the title of this Master's Thesis of Computer Science, could you possibly explain what it is about. The title is: "Design of an Object-Oriented Interface for Message-Based Communication".

Thanks for any help
