  - Network topology can be viewed as a geometric representation of all the links in a network.
  
  - Star topology has a central controller or a hub. 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 Mesh topology, every node has a dedicated point-to-point link to every other node.
  
  - In Bus topology, one cable acts as a backbone to link all the nodes in the network.
  
  - In Tree topology, nodes in a tree are linked together to a central hub. Not every device connects directly to the central hub. Nodes can also connect to a secondary hub that in turn connects to the central hub.
