X window server
http://en.wikipedia.org/wiki/X_Window_System


NeXTSTEP came with a set of libraries and tools to enable programmers to deal with the window manager in an elegant manner. The libraries were called frameworks. In 1993, the frameworks and tools were revised and renamed OpenStep, which was itself later renamed Cocoa.

Cocoa enables your application to receive events from the window server and draw to the screen.

Programming with the frameworks is done in a language called Objective-C.

Objects, Classes, Methods, and Messages

An object takes up memory and has variables inside it.

Classes are structures that can create objects. Classes specify the variables that the object has, and they are responsible for allocating memory for the object. We say that the object is an instance of the class that created it.
To call a method, you send the object a message.


6p
Frameworks

A framework is a collection of classes that are intended to be used together. The classes are compiled together into a reusable library of code. Any related resources are put into a directory with the library. The directory is renamed with the extensioin .framework. You can find the built-in frameworks for your machine in /System/Library/Frameworks.

All Cocoa applications use two of these frameworks: Foundation and AppKit.
