Networks

1. ADVANTAGES :)

   • easy to print from anywhere
   • easy to access files from anywhere
   • a group of computers connected together so they can comunicate
     • no internet required

2. DISADVANTAGES :(

   • if one computer gets a virus, then all networks do
   • expensive
   • difficult
   • more room for error

3. WAN

   • wide area network
   • usually connected through public networks
   • several computer networks connected together

4. LAN

   • Local area network
   • may link the computers within a home, office, or campus

5. TOPOLOGYS

   • ring topology
     • cheap
     • high chance of catastrophic failure
     • difficult to expand
     • no collisions
   • bus topology
     • cheap
     • high chance of catastrophic failure
     • lots of collisions
     • slows down as more computers are added
   • star topology
     • no collisions
     • expensive
     • depends on a switch
     • low chance of failure

6. IP ADDRESSES

   • unique value assigned to every computer on a network, used to identify it
   • range from 0.0.0.0 to 255.255.255.255
     • over 4 billion combonations
   • when a computer is added to a network, it is assigned an IP Address
