In fact there are three basic font families, namely: sans (or sans-serif), serif, and monospace, and “Verdana”, “Georgia (or Times New Roman)” and “Courier New” are three corresponding fonts we usually use under Windows, while in Linux we may use these three equivalents: “Bitstream Vera Sans”, “Bitstream Charter”, and “Bitstream Vera Sans Mono”.
These are three sample pages under Ubuntu:
And these are under Windows XP:
