What is the difference between Granulated Sugar and Preserving Sugar?!
Another type of sugar used to make jam is 'Jam Sugar' which has added Pectin and is used with fruits that are low in natural Pectin. It's designed to dissolve slowly thanks to the crystals being larger than ordinary sugar which means that you don't have to stir the jam as often and that it's less likely to burn.
Answers: Preserving sugar is used with fruits high in natural Pectin. The sugar crystals are bigger than normal, household sugar (granulated) and so dissolve slowly and give a clearer jam than you'd achieve if you used ordinary sugar.

Granulated Sugar is white sugar
Preserving Sugar would be saving it
one is a type of sugar, granulated being granular... your basic sugar. Confectioners sugar, for instance, isn't granulated.
"Preserving" is just a word that means saving. I haven't seen the term used with sugar before. In relation to food, it would mean a means of keeping it fresh, or keeping a food item from going bad.
No difference at all.
