Network topologies
1.
2.
3.
4. In Mesh Topology every device has a
Point To Point link with every other
device on Network.
5. Advantage
Traffic problem can be avoided.
If any one link gets damaged it could not affect
others.
Disadvantage
Very expensive
Can’t be used in WAN
6. In Star Topology every device is connected to a central
Main Computer Known as Server or Hub.
7. Advantage
Less expensive.
Easy installation.
If one device fails, others will not be affected.
Disadvantage
Dependency on one central computer
Large in size.
8. It is Multipoint, In which all the devices are connected
to a central cable known as Backbone.
9. Advantage
Ease of installation.
Less cable is used.
Disadvantages
Difficult reconfiguration and fault isolation.
Difficult to add new devices.
Dependency On Backbone.
10. In this Topology, each device has a dedicated
connection on either side, forming a Ring.
11. Advantages
Easy Installation.
Easy fault identification.
Disadvantages
Unidirectional Traffic.
Break in Ring could break entire network.
12. It is a Combination of Star and Bus Topology, and
the devices are connected in Hierarchal
Configuration.
13. Advantages
Easy Installation and Maintenance.
Compatible with all Devices.
Disadvantages
Dependency on Servers.
Dependency on Back Bone.
14. S.

Types Cost Speed Robustness Used In
1. Star Topology Less Fast No WAN
2. Ring Topology Less Slow No LAN
3. Bus topology Medium Medium Yes LAN
4. Mesh Topology Expensive Fast Yes LAN
5. Tree Topology Expensive Medium Yes MAN
