The ACM and IEEE-CS joint curricula for Computer Science suggests that there is a preliminary Data Structures & Algorithms course, followed by an Algorithms course. Many universities follow that pattern.

Look on google and you'll find a noticeable difference in the books on offer for each.

In my experience, the Data Structures and Algorithms course was more applied. You're writing code (in my case C++) that uses linked lists, stacks, etc to solve problems. This work is done in the context of building more solid programming my skills in the language being used.

Then, in the Algorithms course, it is much more math intensive, and you cover more complicated algorithms and data structures. I didn't have to write one line of code in my Algorithms class (although I did so that I could understand some of the concepts surrounding Red Black Trees, AVL trees, etc)
