I was attempting to respond to Garrett's assertion; apologies for the confusion. :(

To actually answer your question, RaTcHeT302, downsampling is taking an image at a given resolution and, using some kind of image filter, converting it to a lower resolution. Downscaling is intentionally rendering a 3D scene at a higher resolution than the current monitor resolution, downsampling the generated frames to the current resolution, then displaying them. Put another way, downscaling is the reverse of upscaling. The difference is that downsampling can be done on more than 3D scenes (downslampling is what's typically used whenever a game renders textures at half-resolution, quarter-resolution, etc.), while downscaling specifically deals with how a 3D scene is rendered by the graphics card. Thus downsampling and downscaling are actually different, despite the latter using the former during its normal operation.

Also, I don't know if glossary pages are functionally different from wiki articles, so you'd have to ask someone like soeb or Garrett for that.
