Topology

• Topology


  Refers to the structure of the network
• Mesh


  Topology where devices may not all be connected to each other (partial mesh) or are all linked to every other device (full mesh).
• Partial mesh

  All of the devices are not connected to each other.

  A) Partial Mesh Topology

  
• Full mesh

  Every device in a full mesh topology is linked to every other device.

  A) Full mesh topology

  A) Star Topology

  
• Why is Star Topology the modern LAN setup?

  • Single device is easier to protect.
  • Switch in locked closet.
• Hybrid Topology


  Combines 2 or more of the other topologies into a single network.
• Point-to-point topology


  Network connection that is one-to-one.
• Point-to-point topology

  No switching (discovering technology) involved.
• Point-to-point topology

  No Ethernet protocol
• Ethernet protocol

  Uses MAC addresses to find devices.
• What is this topology?

  A) Point-to-multipoint

  
• Backbone

  Central connection point for other connection points.
