Networks

1. star topology

   • expensive to install
     • if a hub or switch fails the whole system is down

2. ring topology

   • cheap to install
     • one cable per computer
       • no collisions
         • only 1 computer is transmitting on each cable
           • high chance of catastrophic failure
             • if any cable breaks or any computer goes down the whole entire network fails

3. Bus topology

   • cheap to install
     • high chance of catastrophic faliure
       • lots of collisions
         • slows down as more computers are added

4. types of networks

   • The internet
     • PSN
