     • the computers have wires connecting them to the main cable
     • a old style of topology
     • bus Topology is cheap and easy to setup
   • Ring Topology
     • Ring style Topology has computers connected in a ring
     • the communication only works in one direction
     • if one cable breaks the system goes down
     • ring topology is cheap to set up and fast
     • high chances of bad problems
     • its hard to add computers
   • star Topology
     • all computers a connected through a central switch
     • this switch directs the traffic to the correct computers
     • most popular network as it's fast and easy to use
     • if one computer dies the others are fine. but if the switch breaks it all fails
