It tells how to convert your artwork to physical units. So essentially its how many pixels form an inch. If you design for print you should set it to 150-300 and type physical dimensions of your output (not pixels). If not leave it as 72.

For historical reasons 72 means value not set, which in turn means designed for a screen device. (Why 72? Adobes internal unit is a postscript point so 72 pixels per inch means one internal unit equals to one pixel which is nice if the unit is meaningless for you)
