A CDA is a program which is listed in the menu you get when you press
control-command-ESC.  The text-based control panel is an example of a CDA
(which stands for "classic desk accessory", btw, meaning that it can be used
from "classic" [8-bit] programs) 

An NDA is found in the apple menu in a desktop program.  NDA stands for "New
Desk accessory", indicating that it can only be used in "new" programs (or
more precisely, Apple IIgs software that uses the desktop interface)

Both CDAs and NDAs predate GS/OS (They've been around since the first
version of ProDOS 16) so they'll work in any version.  Note that most recent
desk accessories will require at least system 5, and many require system 6.
Check the documentation for the specific desk accessory.
