Advantages of the Ring Network:
i) No wiring closet space required
As
we know that there is only once cable connecting each terminal to its
immediate neighbors, it is not necessary to allocate space in the
building of wiring closets.
ii) Short cable length
The
cable used, in a ring network is comporting to the bus, but it is
smaller then the star network. This means that less connection will be
needed, which will in turn increase network reliability.
Disadvantage of the Ring network:
i) Difficult to diagnose faults
Whenever
any terminal gets failed, that will effect all others. It may be
necessary to check (examine) a series of adjacent terminal to determine
the faulty terminal.
ii) failure of terminal causes network fail
As
we know that the communication or transmission of data on a Ring
network goes through every connected terminal on the ring before
returning to the sender. If any terminal fail to pass data through
itself. The entire network has failed and no data can flow until the
defective terminal has been removed from the ring.
iii) Network reconfiguration is difficult
If
any one wants to modify the geographical scope of the network or want
to add any other terminal than ring type network causes problem because
it is not possible to shut down a small section of the ring while
keeping the majority of its working normally.
