Network Topology

• Network topology

  The arrangement of nodes in a computer network to enable communication
• Network topologies

  • Bus
  • Star
  • Ring
  • Mesh
  • Hybrid
• Bus topology

  • Common transmission medium that all nodes are connected to
  • Data transmitted is received by all nodes simultaneously
  • Bi-directional data flow
• Ring topology

  • Nodes are peer-to-peer
  • Unidirectional communication
  • Uses a token to determine which node can transmit
• Star topology

  • All nodes connected to a central hub/switch
  • Communication must pass through the central node
• Mesh topology

  • Each node directly connected to every other node
  • Provides 100% fault tolerance
• Hybrid topology

  A combination of two or more different network topologies
