Difference: Instructions are just a list of things to do. Objects are things (“the real table is the one that our common sense sees”) Thinks of the world the way we see the world before we learn physics. Object Orientation was used because when programming it is easier to organize “Small Talk” first programming using object orientation: Famous because it used a mouse and therefore pointed at things instead of typing in commands Organizing things into objects is very easy for our minds. Just as you forget the physics table, after you leave physics class. We live in the world of objects 99% of the time, and go into physics world when you go into physics class.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
