Network Topologies


Network Topology Refers to the way a network is laid out either physically or logically.Network Topology  can be viewed as a geometric representation of all the links in a network.
 
  • Mesh Topology
  • Star Topology
  • Tree Topology
  • Bus Topology
  • Ring Topology
  • Hybrid Topology


  • In Mesh topology every node has a dedicated point to point link to every other node.
  • In star topology each device has a dedicated point-to-point link only to a central controller, usually  called a hub.The devices are not directly linked together.
  • In Tree topology nodes in a tree  are linked to a central hub.Not every device connect directly to the central hub.Nodes can also connect to a secondary hub that in turn connect to the central hub.
  • In Bus topology one cable acts as a backbone to link all the nodes in the network.
  • In Ring topology each node has a dedicated point-to-point link on either side of it.
  • Hybrid topology is a combination of several topologies of sub-networks linked together in the large topology. Different topologies are connected to each other via star topology.
