In PCB manufacturing, a jumper wire is just a wire soldered between two points. A designer might or might not install jumper pins like those you refer to.
Regarding the use of a 0-ohm resistor instead of a jumper wire: wires are rather annoying to deal with in pick-and-place machines, while a 0-ohm jumper can be reel-loaded like any other part.
