Networks

1. Network Topology

   • Bus Topology
     • Advantages
       • Cheap to install (only one wire needed)
     • Disadvantages
       • High chance of catastrophic failure (a break in the central cable takes out the entire network)
       • High chance of collisions (multiple communications on the same cable that corrupt each other, slowing down the network)
       • More computers mean more collisions, so the network gets slower as it gets bigger
   • Ring Topology
     • Advantages
       • Cheap to install (one cable per computer)
       • No collisions - only one computer is transmitting on each cable
     • Disadvantages
       • High chance of catastrophic failure (if any cable breaks or any computer goes down, the entire network fails
       • Difficult to add new computers
