Topologies – defines the manner in which the network devices are organized to facilitate communication

Bus

  • All transmissions travel full length of the cable and receive by all other stations
  • Single point of failure n the cable
  • If one of the links between any of the computers is broken, the network is down
  • Primarily Ethernet
  • These networks were originally designed to work with more sporadic traffic

Ring

  • Unidirectional transmission links form closed loop
  • Token Ring and FDDI
  • Similar to the Star topology, however there’s a device called a Multistation Access Unit (MAU)
  • MAU works the same as a hub, but with Token Ring networks instead of Ethernet networks
  • These networks were originally designed to serve large, bandwidth-intensive applications

Star

  • Nodes connected to a central LAN or a junction box called a hub or a concentrator at the center of the network
  • Provides reliability and often used by Bus and ring topology as the physical connection

Tree – branches can have multiple nodes

Mesh – all nodes are connected to every other node
