When you adjust levels, you are adjusting the range of the brightness/ darkness levels in an image.  This is determined through a histogram. The histogram displays the distribution of the different light value in an image. For example, a dark image would have a lot of value at the dark end of the spectrum (left hand side of the histogram), a bright image would have a lot of values at the bright end (right hand side).
