26

Allow users to configure devices or change their operation by connecting or breaking circuits to implement different functions

Jumper

27

Small piece of plastic and metal that is placed across two circuit ends to make a connection, or removed to break a connection

Jumper

28

When power is applied to the device, it detects which circuits have been opened or closed

Jumper

29

A cable that connects one device to another device or power source

Pin connector

30

Wires in a pin connector can be tested for continuity by ___
