Now the Project Manger wants to build a computer network for the project smooth running of the project. The project details are given below: Project Duration: 1 year (Extendable) Required Resources: 12 computers+ 1 printer+1 scanner Future enhancements: 8 to 10 computers may be added For such type of scenario, which topology is most suitable for network and why? Justify your answer. | ||||||||||||||||||||||||||||||||
| Solution:
Answer:
The most suitable topology
for such a network is “Star Topology”.
By this type of topology the computers will be connected with each other using
a “central hub” by which we can
connect more computers with the network at any time without any breakage or any
problem in the network. So, Star Topology is more reliable than that of
other like “Ring Topology” because
if a computer failed to work or have any problem it will not affect the entire
network. So, We can replace computer at any time or can also add computers
without any failure of the network. We can also share printer or scanner with
entire work.
Explanation:
Comparison of all
Topologies.
Ring Topology:
If we establish a network using
Ring Topology it will stop entire network in case of a single node or computer
failure. So, it is not so reliable to use in such an office.
Bus Topology:
If we install a Bus Topology
for such a network it will be more reliable but it will be very slow in
performance.
Star Topology:
If we use a “Star Topology” it will reduce all such problems and the
network performance will be faster and reliable and in case of fault of a computer
or node the entire network will not affected and we can easily replace or can
add more computers in this network using central hub.
