3.4 How To Set Jumpers
You can configure your board by setting the jumpers. A jumper consists of two or
three metal pins with a plastic base mounted on the card. By using a small plastic

, also known as the jumper cap (with a metal contact inside), you are able to
connect the pins. So you can configure your hardware settings by

jumpers.
Jumpers can be combined into sets that are called jumper blocks. When jumpers are
all in the block, you have to put them together to set up the hardware configuration.
The figure below shows what this looks like.
