Which is better, a random orbital sander or just a orbital sander?

I was wondering if there is difference between an orbital sander and a random orbital sander?

An orbital and a random orbital sander are not the same and are designed for different applications. An orbital sander is better for finishing sanding and more delicate surfaces. A random orbital sander is better suited for rough or abrassive sanding. For more information, go to this article.
