<networking> 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).
