Network Topologies

Network Topologies

1. Bus Topologies

   • Advantages
     • Cheap to install (Only one wire needed)
   • Disadvantantages
     • High Chance of castastrophic failure (A break in the cntral 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

2. 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

3. Star Topology

   • Advantage
