Authentication is the process of confirming that someone is who they say they are, typically via a username password pair, although that is certainly not the only means of authentication.

Authorisation is the process of determining what the authenticated person can do, such as view some data, change the data etc. Sometimes called permissions.

Yes, the program will need to know with whom it is dealing with before it is able to decide what they are permitted to do.
