There is more than one way to think about dividing up a pizza. First, there is the familiar method of dividing it into slices. Alternatively, you could divide it into layers: topping, cheese, sauce, crust. Theoretically, you could also divide it into its basic ingredients: flour, water, tomatoes, garlic, milk. Each method makes a different contribution to your enjoyment of the pizza. The first method (slices) is best when you're getting ready to eat the pizza; the second is best when you are deciding what to order (such as pepperoni with extra cheese); the third is best if you are concerned about nutrition (needing to know the exact ingredients to calculate calories).
The same is true for Mac OS X. There are multiple ways to look at it and take it apart. Each way makes its own contribution to your understanding of the OS. In this chapter, I look at the major ways to "take apart" Mac OS X. Having at least a minimal knowledge of Mac OS 9 will help, as I occasionally make comparisons between the two OS versions. But even if you've never used Mac OS 9, you'll be able to follow along.

The Layers of Mac OS X: Aqua
Aqua is the name given to what most users think of when they think of Mac OS X: the user interface, the Finder, the Dock, the windows, the translucent buttons, the high-resolution icons, the menus, and all the rest. Many users may never explore Mac OS X beyond its Aqua layer.
From this perspective, a user upgrading from Mac OS 9 will feel quite at home, at least initially. Much still works the same way. You still double-click icons in the Finder to launch them; you still choose the Save command from an application's File menu to save a document; you still open a folder icon to see its contents.
But you will soon notice some significant differences: a new column view, a very different Apple menu, the Dock. I discussed the basics in Chapter 3, when I presented an overview of Mac OS X.
