Wanted to know which devices a cable is to?

I've been tiding my bedroom and I encountered cables with unusual connector shapes (to me).
I wanted to know which devices these cables belongs to, but it's a long time since I didn't use them and I don't figure it out. Even maybe I just droped the original devices and I shouldn't need these cables any more.
I can provide the photographies of the cables and you shall tell me some devices that you bring into your mind on these cable's images, so I jog my memory about my own devices.
Thanks.
