Jumpers and DIP Switches

The last components of the motherboard we will discuss in this section are jumpers and DIP
switches.

These two devices are used to configure various hardware options on the motherboard.
For example, some processors use different voltages (1.5, 3.3, or 5 volts).

You must set the motherboard to provide the correct voltage for the processor it is using.

You do so by changing a setting on the motherboard with either a jumper or a DIP switch. Motherboards often have either several jumpers or one bank of DIP switches.

Individual jumpers are often labeled with the moniker JPx (where x is the number of the jumper).
