gaps
Explanation:
If you have an image processing tool like Photoshop, you can see what they mean: the histogram shows how many pixels (y axis) in the image use a certain tone level (x axis). If the image is not well balanced, in the histogram you will see actual "gaps" - i.e. there are no pixels in the image for some tone levels.

You can see what these histograms look like in the link below.
