advantages:
1.Conceptually Simple :
Ethernet is simply daisy-chained together with
coax cable and "T" adapters. There are usually no hubs,
transcievers, or other devices used.
2.Relatively Inexpensive:
Due to the simplicity inherent in the design of Ethernet,
it can be an inexpensive technology to implement.
3.Noise Immunity :
The coaxial cable used in a Ethernet network is very well
shielded, and has a very high immunity from electrical
noise caused by outside sources.
Disadvantages:
1.Difficult To Change:
Reconfiguring a ethernet is somewhat difficult to do once
it is in place. Any changes to the network will result in
at least some "down time," as the bus must be broken and a
new section spliced in at the point of the break.
2.Fault Intolerant :
If any device or cable section attached to the network
fails, it will most likely make the entire network go down.
3.Difficult Troubleshooting
Ethernet networks are very difficult to troubleshoot. There
is no easy way to determine what node or cable section is
causing a problem, and the network must be troubleshot by
a "process of elimination." This can be very time consuming.
4.Specialized Cable
The RG-58A/U coaxial cable used in Ethernet networks can
not be used for any other purpose. In the event that the
network is changed to another type, then the cable will
have to be replaced.
