About Star Topology as follows:
In a star network, a central computer is connected to several other nodes
in a point-to-point fashion.  All data transferred from one computer to
another on the network must pass through the central computer. All
devices are connected to a central hub.


Advantages for the star topology as follows:

troubleshoot easily, expand easily, disrupt individual computers when
cable break down.


Disadvantages for the star topology as follows:

Use more cable,affect the whole network if the server fails.
