Now, we have zoomed in much closer towards the screen, and we can see from this photograph that the lines are not continuous at all! In fact, they are all made of discrete pixels. At this resolution, the lines look quite fragmented. (Note that no anti-aliasing techniques are being used in this example. If anti-aliasing were used, we would still see a line as a collection of pixels, but the intensities of the pixels would not be the same. This helps to 'smudge' out the jaggedness of the line.)
