Networks

1. Topologies

   • Bus Network
     • Advantages
       • Easy to install
       • Cheap to install, as it doesn’t require much cable
       • If a computer fails the network continues to work
     • Disadvantages
       • Speed of data traveling through network is slow
       • If the network cable breaks, none of the computers can access the network
   • Star Network
     • Advantages
       • If a cable/computer breaks, all the other computers will still be able to access the file server
       • Direct access to the file server means the access is fast
     • Disadvantages
       • Direct access to the file server means the access is fast
       • Expensive to install due to the amount of cables needed
   • Ring Network
     • Advantages
       • Cheap network to setup
       • Data speed is continuous (no data collision as the data travels in one direction)
     • Disadvantages
       • If any computer or the network cable breaks, it can affect the whole network

2. LAN

   • Local area network
     • A network that covers a small geographical area e.g a school network

3. WAN

   • Wide area network
     • A network that covers a large geographical area e.g the internet
