What Is the Difference Between Terminal and AppleScript?

I have enjoyed your recent videos of definitions of technical terms. As a recent Mac user I would like to see defining videos of Terminal mode and AppleScript. Are they the same? When would you use one or the other? Why would you need to use one or the other? Is Terminal like DOS Command Line on a Windows computer? How would one learn how to use Terminal or AppleScript? Etc.
Thanks
