Network

1. Disandvantages

   • It is extremely expensive as you have to buy hardwares and buy wiring which will equal an expensive pay
   • you will need an expertise to add all networks
   • you could get malware- a virus

2. Advantages

   • store all your files
   • share resources such as printers
   • you can login to different computer and access to files

3. topology

   • disadvantage
     • in the bus wire topology if the wire breaks, the whole netwrok breaks
     • data collision can occour
     • catastrophic failure on some topologies
     • in ring topology if for example a compute wants to print, to get to printer it has to pass it to all the other computer in the ring topology
     • star topolgy is expensive
   • advantage
     • most are cheap
     • easy to set up
     • star topology is fast

4. IP Address.

   • it is a unique value assigned to evry computer in a network to identify it
   • Messages have an IP Addreaa to know which computer they are sending it to
   • Computers cant all have same IP Address as the most it can go to is 255.---.---.-- so they are all specialised in their own network
     • they are all specialised in mini networks
   • IPv6 is a thing that can specialise computers now up to 128 binary bits which supports trillions of computer to have their specialised IP addrress
   • IP addresses are in binary which can only go to a limited amount of numebrs
