Network topologies

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