Redhat Satellite Standalone without capsule server

Hi Guys,

I am confused about Satellite and Capsule server. I installed Redhat Satellite 6.2 and I don't have any capsule server under Infrastructure tab. I have some questions about capsule server.
1- Do I need a capsule server for managing my environment. Is there any additional feature that capsule server can do but Satellite itself can't.
2- I know when I install the satellite it installs internal capsule server on it. Is this true? Can I see configuration of that internal capsule?

Thank you for your help.
