Does the 3rd Gen Ipad 32GB MC706C/A have a USB port? What doesn't it have?

I'm wonderdering what the Ipad 3rd Generation 32 GB MC706C/A is missing any of the options that any other models might have (as you can tell this is my first enconter with any Ipad) does it have an ISB port? Please tell me what it does not have, so I can decide whether to purchase it. (I wanted WiFi only) are the cameras the same on all the 3rd Gen Ipads?
