What component has a black stripe in the centre (it looks like a diode)?

A small component about the size of a resistor or signal diode with a single black stripe in the centre is a zero-ohm resistor, it is really just a wire link! These components are used on commercial PCBs because they are easier for machines to handle than small pieces of wire. The single black stripe is logical because it means zero in the resistor colour code. Ordinary resistors have at least four stripes. Diodes have a single stripe near one end, not in the centre.
