Full frame and FX are the same thing, sensor size approximately the same size as a 35 mm film. Cropped and DX is the same and is about 2/3 the size of the 35 mm film size.
Full frame is FX, cropped sensor is DX. The difference is essentially a size difference. I know that the FX sensor is 24x36mm which is the same size as the original 35mm film was. DX is 1.5x smaller. So, if you use the same focal length lens, you will see just a smaller portion of the image on the DX where you will see the whole thing in FX.
Google could be your friend as there are a lot of sites that explains it maybe better than I.

Full frame is the same as FX and refers to a 35mm equivalent sensor. A crop sensor AKA a DX sensor is smaller, about the size of APS film or about 1/3 smaller than FX. Given the smaller sensor, a lens has an angle of view of a lens 50% longer, so a 50mm lens behaves more like 75mm.
Samsonite - would it be possible for you to fill out your profile? This will help out a lot so that other people who are trying to answer your questions will have a better idea on what to recommend or suggest. Thank you.
To be more specific, FX is Nikon's designation for cameras that have a "full frame", 35mm size sensor and for lenses meant to work with said cameras. DX is their designation for cameras with the smaller than 35mm sensor and for lenses meant to work with only the DX cameras.
Third party lens makers like Sigma use different designations for FX and DX compatible lenses.

I think he must have gotten the answer, and then some...
Depending on how much you are willing to pay for a camera. You can learn more about them from the official website including their lens line-up and prices.

Thanks guys, ye I sure didwill fill out my profile tonight. So would full frame be for the professional range of cameras? Is there a variation in price between fx and dx lenses?
Crop sensor lenses and camera bodies are cheaper than their full frame equivalents. Smaller image areas for smaller sensors means less glass, which means lighter and smaller. Do if you want the bigger sensor, which has benefits if you know how to use them, you can expect to pay more both in dollars and in the weight of the gear you carry around. And they tend to be even heavier and more expensive than that, since photographers who care are likely to demand stronger and more reliable components. The D600 feels more like a big consumer body, while the D800 is heavier and feels more professional and higher end.
