- - - - So it will not send a message if the receiving computer is not there
  - - - It also filters data packets to see which devices have asked for them.
- - - - User cannot change it
  - - - Web server
        
        Host websites and generally handle requests for static information
        
        Used to manage the website in the server
      - File server
        
        Provides file systems
        
        Gives network users a place to save and load their data and files
      - Print server
        
        Makes easy for devices to connect to a printer
        
        Removes the need for devices to install printer driver or using cables
        
        manage queue service printer
      - E-mail server
        
        Stores email messages
- - - - Criminal hackers attempt to break into networks in order to steal personal information and banking details because with a network it is easier to gain access
    - - networks make it easier to share viruses
- - - - if one cable or device fails, then all the others will continue to work
        
        high performing as no data collisions can occur
    - - It is very expensive to install
        
        Extra hardware is required
        
        all the devices connected to it will have no network connection if a hub or switch fails
    - - each device on the network has its own cable
        
        This is the most popular way of setting up a LAN
  - - - Transfer data quickly
        
        No collisions
    - - If the main cable fails or any device is faulty all the network falls,because it is a cycle
    - - Is connected in a ring so each one is connected to two other devices.
        
        Each data packet on the network travels in one direction
  - - - Each device is connected in a ring so each one is connected to two other deviceE
        
        Each data packet on the network travels in one direction
        
        Each device receives each packet in turn until the destination device receives it.
    - - Easy to install
      - Cheap to install
    - - if the main cable fails or gets damaged, the whole network will fail
      - Slow
      - Every workstation on the network 'sees' all of the data on the network
