What is the key difference between a Web application and a Web Portal?

Question

I taught i had a clear view of the difference between these, but giving it a deep i got confused.

Can someone help with a comparison, please?

A web application offers a clear and focused service. A web portal is rather a sort of "start page" that contains links to a variety of resources and services. See here:
