What is the difference between scoped notification & alerts? Is there any term called scoped notification?

"Scoped notification - Scoped notifications serve advisory information for the user that is not important enough to justify an alert. It is often presented as a status bar scoped to the container. They are not dismissable."

"Alerts - Alerts which cannot be dismissed."
