39. CAN Bus
The physical layer uses differential transmission on a twisted pair wire.
A non-destructive bit-wise arbitration is used to control access to the
bus.
The messages are small (at most eight data bytes) and are protected
by a checksum.
There is no explicit address in the messages, instead, each message
carries a numeric value which controls its priority on the bus.
An elaborate error handling scheme that results in retransmitted
messages when they are not properly received.
There are effective means for isolating faults and removing faulty nodes
from the bus.
