NETWORK

1. DISADVANTAGES

   • there can be catastrophic collusions
   • if you add more computers the network will be slower
   • you can only print out of the devices that are connected

2. ADVANTAGES

   • share recources such as printers and internet connection
   • use the same logins on every computer
   • save files on every computer

3. topology

   • bus
     • it is cheap to install but it has lots of disadvantages for example it has a high chance of catastrophic faliure and collisions
   • ring
     • its fast and easy to install but it is difficult to expand and it has a high chance of catastrophic faliureit has no collisions
   • star
     • it has a low chance of faliure no collisions .but is expensive and it depends on one switch

4. internet

   • the internet is a giant mesh of computers
   • there are multiple diffirent routes between any two nodes
   • it is impossible to break the internet, since another router can always be found
   • data is split into small chunks called packets
   • each packet is sent along the lowest cost route
   • the packets are re-assembled on the other side
