Out of interest, why is it called "hinted" and not "example" or something? I'm guessing it's font lingo?
Basically for fonts to look good when placed on a square grid (pixels) there is a method called hinting which as the name implies gives hints to the font renderer on how the fonts should be drawn across this grid in order to best preserve the intended look of the font and be readable, this has the greatest impact when you are using a very limited size grid such as in small font sizes.
Here's the font: https://www.google.com/fonts/specimen/Roboto

Kudos to Stephen Coles for keeping that article updated as the font has evolved and improved.
