Bread that has been dried and ground into a fine powder with or without the crust is called breadcrumbs. It's is made using fresh and stale bread and can include the crust. Grounded, it is a light pink or brown in color. Used mostly to coat foods that are to be deep fried for a crunch, it has a crumbly texture. Fresh crumbs are used more for stuffing than coating foods since they don't provide the same crunch.
Usage

Other than as a coating for fried foods like cutlets and as stuffing for various meats, breadcrumbs are also used in au gratin dishes.
