What's the difference between the Application Developer Tools and Server Applications CD

I have 2 questions about Sql Server 2005.

1. I have 2 sets of CDs, one is called Sql Server 2005 Developer Edition, Applications Developer Tools, and another one called Sql Server 2005 Developer Edition Servers Server Applications.

I installed the Applications Developer Tools on my development pc, and I was able to use create and populate a database, and use Sql Server Management Studio fine. I wonders what 's the Servers Server Applications set of cds for.

2. I just like to install Sql Server 2005 on a test pc also. Can I use my Developer Edition Applications Developer Tools to install it ?

Thanks.
