Authentication is the process of validating that a person is whom he/she says he/she is.
Once a person is authenticated, Authorization is the process who let the person access or not some places.

Authentication is validating person's identity that he or she is the genuine user, example is smartcard has pin feature, in your ATM you need to use PIN, Similarly when user login one need to provide his userid and password (basically logon creditial), if that matched then only you can successfully login in the site.
Authorization is giving speficific role to a set of member (groups), like administrator can do these tasks not other use, this is done using rold based authorization.
hope this help you.
