Font hinting (also called instructing) is the use of mathematical instructions to adjust the display of an outline font so that it lines up with a rasterized grid. At low screen resolutions, hinting is critical for producing clear, legible text. It can be accompanied by anti-aliasing and (on liquid crystal displays) subpixel rendering for further clarity.
