CCNA 1.6: Compare and contrast network topologies (Star, Mesh, Hybrid)

Overview:

Using topologies to discuss networks simply helps us better visualize them.  Network topologies help frame the conversation.  A topology is the study of spatial relationships between parts.  So when used in the context of a network topologies, it normally means the nodes and the links between them.

Study Notes:

  • Physical topology deals with cabling
  • Logical topology deals with the logical path the signal travels on the physical topology.
  • Today we primarily use a physical star with logical bus
  • Bus: all devices connected to a single cable
  • Ring: devices are connected to each other in a ring
  • Star: think switch in the middle and end devices connecting to it
  • Mesh: every device is connected to each other
