CAKE TYPES...Question to be answered

CAKE TYPES: Hi there!! =) I have a story to share with you... During my holiday last week, I fill my free time to learn baking a cake. My mom was guiding me. I've making Chocolate Sponge Cake and Chocolate Pound Cake. From this experience, I realize that method I'm used to make the both cake is totally different. For Chocolate Pound Cake, I need to mix shortening(fat), margarine or butter with sugar first until it very creamy then i adding others ingredients. But... to make Chocolate Sponge Cake, no shortening (fat) are used. It just uses air that is beaten into either the whole eggs or eggs whites to leaves them.

Then,I search for the types of cake in internet. Here, want Ii just found about cake types.

Cake fall into two groups, foam cake and shortened cake (butter cake).

1. Form Cake - This cake have largest proportion of egg than butter cake. It does not contain fat and also called as unshortened cake. To make them be light and soft, they need the air beaten into them along with eggs whites for the soft, rich and light texture. Examples of foam cakes are Angel Food Cakes and Chiffon Cakes.
   
2. Shortened Cake (butter cake) - Also called creamer cake, contain fat, margarine, or vegetables shortening. Frequently, fat we used are in solid form and high ratio of eggs to flour. The uses of fat will add finely textured, and moist cake. Examples of butter cake are pound cake, fruitcake, cheese cake and brownies.

So, after this explanation about cake types, if you understand it, can you give me what type of cake for my Chocolate Pound Cake and Chocolate Sponge Cake that I've been make during my holiday?
