Networks

Networks

1. Advantages

   • Consistent User Experience-
   • Shared Login Information
   • Printing From Every Device
   • monitor what has happened

2. Disadvantages

   • Expensive
   • Room for Error

3. Topologies

   • Star
     • Easy to add new devices
     • Fast (low chance of collisions)
     • Expensive (needs a lot of cabling, and a central switch, which is expensive)
     • Low chance of catastrophic failure (a broken cable only takes out one computer, the rest of the network is fine)
   • Bus
     • Cheap
     • One wire
     • High Chance of failure
     • More computers mean more collisions, so the network gets slower as it gets bigger
   • Ring
     • Cheap
     • No collisions
     • Hard to add new devices
     • High chance of catasrophic failure
       • If one wire breaks the whole network could

4. IP address

   • Unique
   • A unique number that the network knows the computer by to transfer messages
