difference between Authorization and Authentication?

Authentication is a process of identifying a user based on their credentials(means user id and password).

Authorization is process of determining whether an authenticated user is allowed to access a specific resource or not.

In Short,
Authentication is the process of validating a logged in person with user_id and password
Once a person is authenticated, Authorization is the process who check the person access or not for some places.

The "quick guide"
Identification: Who are you?
Authentication: Prove yourself
Authorization: Here is what you can do?
