TOPIC: Admin closure vs Contract closure

What exactly are the differences between Administrative Closure vs Contract Closure? If encuntered in the exam what salient meanings can help me differentiate them?

Kalu,

Contract closure: Closing a single contract on your project. (You may have 20 contracts going on, but you are only closing one).

Administrative Closure: Part of the Close Project or Phase process, in which you close your complete project when you are completely finished with everything, or when you close a phase (at the end of the phase.)
