Jumper
A jumper is a kind of switch which uses a plastic cap with a metal
interior to connect (short) two pins. If a jumper needs to be left open,
you should save the cap for future use by covering one pin only of the
jumper. This has no effect on the function of the board while it keeps
the cap handy. The illustration below shows the side and top views of
a three-pin jumper in which pins two and three are shorted.
Figure 2-22: Three-Pin Jumper Setting Example
With the mainboard oriented in the direction shown in the illustration
above, the pins of each jumper are numbered from left to right in
ascending order.
