Unable to find USB Ports on HP All in One. Is there a diagram showing these?

[Marsha0904]

I'm a Senior Citizen and was given an HP All-in-One desktop by my grandson.  I am unable to locate my USB ports where I can stick my thumb drives into.  Can anyone help?  I was hoping to find a diagram that would show me where they are located.  Thank you.
