data or information between a source and a receiver, the source transmits the
data and the receiver receives it. The distance over which data moves within a
computer may vary from a few thousandths of an inch, as is the case within a
single IC chip, to as much as several feet along the backplane of the main
circuit board. Over such small distances, digital data may be transmitted as
direct, two-level electrical signals over simple copper conductors. Except for
the fastest computers, circuit designers are not very
