output devices. Analog, discrete, and special-purpose blocks can be used on the
same bus.
A fixed length data packet including information to route it from source to
destination with no reliance on previous transmissions.
Resistant to software errors and hardware problems. A fault tolerant LAN keeps
running in the event of a power failure, a disk crash or other major events.
Redundant backbone cabling provides a degree of fault tolerance, so that if the
cable is cut, the network will continue to run.
The way in which devices on a network are physically connected: star, bus, or
