Acceleration is simply using GPU for graphics operations instead of
CPU. 3D accelerator accelerates 3D operations (rendering 3D objects)
and 2D accelerator accelerates 2D operations (bit blits, line
drawing, clipping etc.). On modern computers, 2D graphics are
simulated using 3D without perspective, because 2D accelerators were
almost dropped years ago by graphic cards vendors.
I hope I didn't simplified it too much. ;)
