Terminology and circuit diagram
– A bus system for transferring data
between several participants via joint
transmission path.
– A communication protocol agreement
according which data transfer bet
ween
two more participants carried out. Via this
connection the receiver switched a
different operating mode.
In its most simple form, proto
col can be
defined the rules deter
mining the
structure, meaning and synchronisation of
communication.

In electronic engineering, control line is
a connection (cable, wire) between one
transmitter and one receiver
