1. Advantages

   • Consistent User Experience
   • Shared Login
   • Files available on all computers

2. Bus Topology

   • Advantages
     • Cheap
   • Disadvantages
     • High chance of collision
     • If the wire breaks, all devices go down
   • One straight wire connecting all computers

3. Disadvantages

   • Expensive
   • Viruses affect all computers
   • Computers can be quite slow

4. Ring Topology

   • Advantages
     • Cheap
     • No collisions
   • All going in one direction in a circle, each device connects to only two others
   • Disadvantages
     • High chance of catastrophic failure
     • Difficult to add new computers

5. Star Topology

   • All devices connected to one switch individually
   • Advantages
     • Low chance of collision

6. IP Addresses

   • External
     • This is the IP address given to the whole building
     • This means alot of the computers seem to have the same IP address
     • This means they don't need to make new IP addresses, originally they thought it was laughable to have over 4 billion devices, but...
   • Internal
     • These are the IP addresses inside the building, they are all unique
     • This means computers on a LAN can send things to other individual computers
   • Internet Protocol Address
