Networks, connections and protocols - Coggle Diagram

- - - - Easier to manage security of files
      - Easier to install software updates
      - Easier to take backups of shared data
    - - Require IT specialists to maintain
      - Can be expensive to set up and maintain
      - One single pint of failure
  - - - Easy to maintain
      - Easier to set up than client server model
      - No dependency on a single point of failure
    - - The network is less secure
      - Can be difficult to maintain a well ordered file store
      - Users will need to manage their own backups
- - - - A LAN cannot connect to WAN without a router
  - - - The grade and iinsulating material affects the bandwidth
      - Cheap
      - Cables are twisted round each other to decrease interference
    - - Are the backbone of the internet
      - Cover longer distances than copper cables
      - Have a higher bandwidth than copper cables
      - Suffer less interference compared to coppper cables
- - - - Excellent back up and recovery option
      - The ability to access data anywhere, at any time
      - Ho hardware is required as everything is hosted on the cloud
      - Room growth, as is easy to scale up and expand.
    - - Ongoing monthly/yearly cost for the privilege to be able to use cloud
      - Lack of control - you are essentially handing over data and info
      - Relies completely on a stable internet connection
      - There may be bandwidth problems, as data transfers relies completely on the connection’s speed of data transfer
- - - - There is no single point of failure
      - Data has multiple routes to travel
    - - Large amounts of hardware, resulting in overall cost being high
- - - - A set of rules used for communicating on a LAN
      - Systems communicating over Ethernet divide a stream of data into shorter pieces called ‘frames’
        
        Each frame contains a source address and a destination address used for error check so that damaged transmission can be detected
    - - The newer Ethernet uses twisted pair cables with a fibre optic link
      - The original Ethernet cables used coaxial cables as a shared medium
  - - - See ‘WiFi’ sector for disadvantages and advantages
    - - Advantages
        
        No cabling - increased convenience
        
        Nodes can be added to the network easily
        
        Easier to share data as no cabling is required
      - Disadvantages
        
        Increased security risk
        
        Decreased transfer speeds
        
        Decreased reliability
