NETWORKS!

1. advantages

   • go on a computer anywere
   • easy access
   • share your work with ease
   • consistance with experiance
   • files available with every computer
   • email with same softwear

2. disadvantages

   • expensive-extra softwear
   • more room for error
     • difficult
     • one gets hacked they all get hacked

3. different types

   • LAN
     • local area network
     • small area
     • one organisation
   • wide area network
     • multiple organisation
       • consists of multiple LANS
   • WAN

4. network topologiess

   • star topologie
     • advantages
       • fast
         • low chance of collisions
           • easy to add new computers
             • low chance of catastrophic
           • disadvantages
             • expensive
               • failure of switch will shut down the hole thing
                 • ip address
                   • each ip address has its own 32 digit code
                   • if there is a collision it sends a message to the person who wrote it
                     • each message has its own ip address
                   • messages on a network has its own ip address
                     • the internet is a huge network with more devices possible to give each one a different ip address
   • ring topologie
     • advantage
       • chaeap
       • no collisions
         • no terminators
     • disadvantages
       • high chance of catastrophic data
         • difficult to add new computers
         • security
   • bus topologie
     • advantage
       • cheap
     • disadvantages
       • high chance of catastrophic failure
         • high chance of collisions
         • more computers mean more collisions

5. mesh topologie

   • developed 30 years ago
     • disadvantages
       • cost expensive
       • building and containing it is hards
       • chance of redundant catastrahpys is high
       • advantage
         • manages high amounts of traffic
           • a failure of 1 device does not break it
         • you can add new devices this does not disrupt it

6. ipv6

   • Image result for ipv6 why isn't it used Adoption of IPv6 has been delayed in part due to network address translation
