Advantages and Disadvantages of Network Topologys.

1.      Bus Topology:

Advantages	Disadvantages
Simple to install and wire.	Any cut in the cable will result in severe communication disruption.
Easy to maintain.	Need to be fixed on priority.
Inexpensive.	It is difficult to affect server, and workstation moves.

2.      Star Topology: 

Advantages	Disadvantages
Addition of new work stations or other network devices is easy.	If the hub or concentrator fails, nodes attached are disabled.
Maintenance network is more organized, easy.	Expensive.
Even if a work cable damaged, the network will still be operative.	Requires more cable length than a linear topology.

3.      Ring Topology:

Advantages	Disadvantages
High bandwidth capacity.	Single cable fault may bring down the network.
Fault location identification.	Difficult to maintain.
Ability to cover relatively larger distances.	Slow since signals goes in sequential order.

4.      Mesh Topology: 

Advantages	Disadvantages
Redundancy.	Cost.
Supported by several hardware and software venders.	Complexity of the topology.
