Almost true. In classful mode the explicit mas may not be used. There are only two parts (network and host) in such case.
May be this page will help you.
Note the classful addressing scheme is rather historic. I bet you will never see network with classful addressing scheme used. It's about fifteen years since I've seen this kind of thing for the last time

I see no error. IP and explicit mask is common to both method. Classfull have class (implicit mask) in advance, while classless have no class (implicit mask).
