The Free On-line Dictionary of Computing (30 December 2018):
daisy chain
    A bus wiring scheme in which, for example,
   device A is wired to device B, device B is wired to device C,
   etc.  The last device is normally wired to a resistor or
   terminator.  All devices may receive identical signals or,
   in contrast to a simple bus, each device in the chain may
   modify one or more signals before passing them on.
   Characteristic of RS-485, of Apple's LocalTalk, and of
   various industrial control networks; also often used to
   describe Thinwire Ethernet (10base2).
