Well to put it simply i will say they are made from 2 completely different products and the way of making them is completely different.
Now given that there are a variety of "chips" and I am not sure which ones you are talking about.
So in a detailed explination
Crackers for the most part a porduct of the bread family (along the lines of a biscuit) or can be part of the cookie familiy it just depends on the products contained with in them. Most of the time they are made simular to the bread side. The consist mainly of flour water and a few other ingrediants. The process for making crackers is quite litteraly a layering process.
Chips on the other hand are pretty much made the same way any way you go about it. American chips are thinly slined potatos that have been fried at high temps for a shot period of time. While European chips are more of the battered french fry style. Both processes of making chips can also be made in the oven.
Now if you are being racist. Then the term Cracker comes from the days of the slave drivers and where dubbed that because the sound that their whips made.
Not sure that a chip is an insult though so I will assume you are talking food here
Damn I am a geek.
