Why deployment.apps but service (dot-nothing) in kubecfg get all?

Time：08-18

When I do kubectl get all, I see

pod/something
service/something
deployment.app/something
replicaset.app/something

Why there's an app following deployment and replicaset? What does app mean here? What's other possible values other than app?

Thank you!

The app part is an API Group. The Pod and Service resource belongs to the "core" API Group, so it does not have to be written.
