Aliasing
Effect produced when a high-resolution image is put onto a display of lower resolution. Aliasing for example happens on computer displays when drawing non-horizontal or non-vertical lines, as these cannot be displayed without information loss on a pixel grid. Anti-aliasing is a method used for smooth scaling.
Anti-aliasing
