Networks

Networks

1. Advantages

   • shared logins
     • consistent use
       • Share resources
         • you can get it on all computers
           • shared files

2. bus

   • advantage
     • cheap to install one wire only
   • disadvantage
     • high change of failure
       • it becomes slower as there are more computers
         • more chance of collision

3. disadvantages

   • less creative
     • lack of individial control
       • more expensive
         • difficult

4. ring topology

   • advantages
     • Cheap to install (one cable per computer
       • No collisions - only one computer is transmitting on each cable
   • disadvantage
     • High chance of catastrophic failure (if any cable breaks or any computer goes down, the entire network fails
       • Difficult to add new computers

5. star

   • advantage
     • Fast (low chance of collision)
       • 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)
   • disadvantage
     • Expensive (needs a lot of cabling, and a central switch, which is expensive)
       • Failure of the switch will take down the network

6. ip address

   • an ip address is where you get assigned a unique number so that when u resive something it doesn't send to someone else
