Difference between Portal and Web application access in APM

@Amolari:

Thank you for writing here.

@ Nathan: Yeah. You are correct buddy. It's named as portal access in 11.x version whereas it's web application access in 10.x version. I am bit confused by reading both the documents :) .

Anyways, I thank both of you to help me here.
