Ribs are a relatively cheap cut of pork as they contain a smaller ratio of meat to bone. The discarded bones from chops are sold as spare ribs - pieces that have some meat, but not enough to be classed as proper chops. These can be marinated and grilled or barbecued. Ribs are also cut and sold in the same way as chops, with quite a large amount of meat still on the bone. The rib joint of pork contains more meat and can be treated like the rack of lamb as a piece that's ideal for open roasting or glazing and can be carved easily between the ribs so long as the chin bone is removed.
