It is a difference in the placement of the priming compound. This compound is sensitive to physical impact, and, being struck by the firing pin, explodes to ignite the gunpowder in the cartridge case. In the rimfire cartridge, the case, made of soft brass, has a folded rim. Primer compound placed inside that folded rim is exploded when the rim is pinched between the firing pin and the mouth of the chamber. Centerfire ammunition has the primer in a pocket at the rear center of the cartridge case. That case has harder brass, and is capable of handling higher pressures than rimfire ammunition. Centerfire ammunition can be reloaded after firing by replacing the primer, powder and bullet. Rimfire ammo is not generally reloadable.
Rimfire primer is in the rim of the casing.
