UPDATE:  Less than 24 hours and the HDMI adapter stopped working. I know it's the adaptor because cable works when I connect my laptop.  Disappointed with this purchase and will be returning it.  ORIGINAL: HDMI connection is an adapter, 2 wi-fi, 1 blue tooth, wired keyboard and wired mouse all need to be plugged in to external ports.  The DVD is a very thin external piece with another cable to plug into USB.  SO out of 8 various USB ports, once everything (apart from HDMI adapter) is plugged in, only 2 slots are available for future use.
