computer networking

1. advantages

   • Cheap to install (only one wire needed)
   • Cheap to install (one cable per computer) No collisions - only one computer is transmitting on each cable
   • Cheap to install
   • Cheap to install (one cable per computer) No collisions - only one computer is transmitting on each cable 
   • Cheap to install No collisions (fast)
   • Fast (low chance of collisions) Easy to add new computers Low chance of catastrophic failure (a broken cable only takes out one computer, the rest of the network is fine)
   • Low chance of failure No collisions (fast)

2. disadvantages

   • High chance of catastrophic failure (a break in the central cable takes out the entire network) High chance of collisions (multiple communications on the same cable that corrupt each other, slowing down the network) More computers mean more collisions, so the network gets slower as it gets bigger
   • Difficult to add new coHigh chance of catastrophic failure (if any cable breaks or any computer goes down, the entire network fails mputers
   • Expensive (needs a lot of cabling, and a central switch, which is expensive) Failure of the switch will take down the network

3. LAN

   • WAN
     • wide aria network
   • local aria network
     • network for everyone in the local aria

4. ring

5. ip

   • each ip has a unuique ip address
   • internal
     • devices in the house
     • external
       • the houses ip addres
