Daisy chain (engineering)

wiring scheme in which multiple devices are wired together

In electrical and electronic engineering, a daisy chain is a wiring scheme. It has multiple devices, which are wired together in sequence or in a ring, similar to a garland of daisy flowers.[1][2]

Daisy chains may be used for power, analog signals, digital data, or a combination of them.[3]

The term daisy chain may refer either to large scale devices connected in series, such as a series of power strips plugged into each other to form a single long line of strips, or to the wiring patterns embedded inside of devices. Other examples of devices which can be used to form daisy chains are those based on USB, FireWire, Thunderbolt and Ethernet cables.[4]
