What's different between PUN and Photon Realtime?

Options
I just download PUN free version via assetstore, and I register a account choose the free plan ,
but I notice that there is another product call Realtime, so I download the SDK and run the demo project,
I even cant fine the Photon setup window that should be inside Unity and so people can set their appID,
So what is the meant different between each other ??
Is PUN just a preparation version of Photon Realtime so made Unity3d developers' life easier ?
But I check the reference page that shows many other game developer who using Photon to dev their multiplay game,
and they all using Both Realtime and PUN.
If Realtime is same as PUN why they should using both of them?
So with these above really is confusing me .
Please :o:o:o:o

    Sorry for the confusion.
    Photon Unity Networking (PUN) is our "best" client package to use. It's simple and well documented and a good start in general.
    The Photon Unity SDK on our page is for developers who like a slim and flexible API which is a bit less tied to Unity and Unity's way of solving things. It's an alternative to PUN.

    Photon Realtime is not another product but a name for one type of Photon Cloud Subscription. For realtime games.

    PUN is a client package for Photon Realtime.
