Topic: Fonts Ascent and Descent

This may sound like a dumb question, but does anyone know what Font Ascent and Descent are? Is this the height of the font? Also I downloaded a C library called CPDFLib from pdflib.com and found some tables that are for calculations of font heights, for instance it contains a short array filled with values that are supposed to be a fonts ascent value or for that matter a fonts char width. So if I have a Times New Roman Font, it will look up the fonts ascent which is .683 and multiply it by the font size to font its height. But does anyone know where I can find out where this .683 came from? Is this specific to a Times New Roman Font?
Any help would be great, thanks in advance!!!!
