Product attributes
Before diving into the creation of products, we need to explore a very important and powerful feature of Magento: product attributes. We have yet to find another common platform that provides the level of sophistication for product attributes as well as Magento.
In Magento, every field related to a product is called an attribute. The description, price, weight, and SKU of a product are attributes. In fact, all the fields that appear by default on a product detail screen are attributes.
But the real power comes in those attributes that you can add to your product screens to capture more granular aspects of your products, such as color, size, kHz, and screen size. Obviously, not all attributes are relevant to all products. For instance, t-shirt size would not be applicable to your furniture products. Fabric would not be a useful attribute for computer monitors. And that's where Magento really shines!
