There are many functions of speed when referring to cameras.
The film speed refers to the sensitivity to light of the light capturing medium.
If you are shooting with ISO 200 film it will take more light or time to produce a correctly exposed image than an ISO 800 film. This property works for both film and digital cameras.
The shutter speed refers to how fast the shutter can open and close. The shutter is part of the camera body. If you take a fully manual camera (Pentax K1000) and remove the lens you can see the effects of shutter speed by looking in to the camera body and changing the shutter speeds manually.
When a lens is attached to a camera the shutter is always fully open, unless your camera has a DOF (Depth of Field) preview button which is being depressed. The shutter closes at the moment the picture is being taken to obtain the correct exposure.
The lens speed refers to the largest aperture possible with a particular lens.
Usually referred to as an f-stop. The lower the number possible, the faster the lens. A lens at f 2.8 is faster than a lens at f 4.5. It refers to the light gathering capabilities of the lens. The ratio is derived by dividing the focal length of the lens by the size of the effective aperture that is allowing light to strike the recording medium. Therefore with a 100mm lens an aperture setting of f8 would have an actual aperture of 12.5mm whereas with the same 100mm lens an aperture of f16 would be 6.25mm.
In reality, there is no term camera speed. The only thing I can think of would be a sales pitch regarding the fastest ISO speed that the camera is designed for, usually ISO 1600 or higher. In reality, you can trick the camera to use whichever film speed you want by adjusting the other values accordingly. You will possibly need a light meter to do this effectively.
To make a correctly exposed image (film or digital) you need the film speed, shutter speed and apertures set correctly to allow the medium to be exposed correctly.
If in doubt, expose the image for the shadows and develop for the highlights.
