whats the difference between a crust of bread or a heel of bread? or between soda and pop (or coke)?

italian is made up of regions, and all its food is regional (there is no such thing as italian food.. there are silcilan dishes, and roman dishes, and tuscon dishes, there are wheat and pork and cheese specialties from the north, and olive and tuna and basil specialites from the south, every where the food is different..

its no surprize that the same food has different names in different parts of the country.. (the north of US ate SAMP, in the south, the same food was GRITS.)

but there is a difference between chipped beef, (beef that has has been cut up into chips (hand cut into small chips)--usually a chef would use 2 knifes, to cut the beef into chips.. (similar to a fine dice)

ground beef is run through a grinder, and pushed through a mill (so that it comes out in little string like shapes.)most times its run through the grinder twice..

when you grind beef, its hard to tell how much fat is being ground in (butchers would add chunks of frozen blood to make the beef (fat) 'redder')--but about 20% is 'normal'

chipped beef is made from somewhat tough cuts of meat, the meat is finely cut (to help tenderize it by cutting up tought connective tissue) and then slow simmered (which will further tenderize it), before being 'creamed' in a white sause.
