  15. 15. • Bus networks: use a common backbone to connect all devices. Network Topologies
  16. 16. Ring Topology • In a ring network, all messages travel through a ring in the same direction (either "clockwise" or "counterclockwise"). A failure in any cable or device breaks the loop and can take down the entire network.
  17. 17. Tree • Integrates multiple star topologies together onto a bus. In its simplest form, only hub devices connect directly to the tree bus, and each hub functions as the root of a tree of devices.
  18. 18. Star • A star network features a central connection point called a "hub node" that may be a network hub , switch or router .
  19. 19. Mesh • Mesh topologies involve the concept of routes. Unlike each of the previous topologies, messages sent on a mesh network can take any of several possible paths from source to destination.
