   • We can share files
   • We can share recorces
   • We can share logins

3. Disadvantages

   • It is expensive
   • There is an increased risk of viruses
   • It could be difficult to make

4. Topology

   • Bus Topology
     • cheap
     • High chance of catastrophic failure
     • lots of collisions
     • slows down as more computers are added
   • Ring Topology
     • Cheap
     • no collisions
     • high chance of catastrophic failure
     • difficult to add new computers
   • Star Topology
     • fast
       • (no collisions)
     • easy to add new computers
     • low chance of catastrophic failure
     • expensive
     • Failure of switch will take down whole network

5. IP address

   • Unique for every address
   • IP address stands for internet protocol address
   • 32 digit bit-binary
