- - - - Any device used to input data into a system
      - Mouse, Keyboard, Mic
    - - Devices which show a response after data has been inputted and processed
      - Monitors, speakers, headphones, printers
    - - Any device which allows a node to connect to the network or send packets around it
      - NIC, Router, Switch
    - - Uses human characteristics as a security mechanism
      - Advantages: Improved security, passwords, can't be shared, system can't be entered without the biometric, verify a person, ease of access
      - Disadvantages: Expensive, set up times, disability concerns, environmental factors (fingerprints readers can't be used in wet conditions), privacy
  - - - SSD
      - HDD
      - Optical
      - Cloud
    - - GPU
        
        A similar piece of hardware to the CPU but it is optimized for handling graphical processing
        
        Handles graphical display to the screen
      - NIC
        
        Required for any device to connect to a network
        
        Converts internet signals back into data
      - Sound Card
      - Fiber Channel Card
        
        Transfers data between Servers, quick transfer speeds, connects data storage
      - Storage Controller Card
        
        Required for a computer to manager and use any and all data storage devices
    - - USB
      - Firewire
      - SD
      - Ethernet
      - SATA
      - Micro SD
    - - SCSI
      - SAS
  - - - Needs to be plugged in constantly, has high processing power and storage, versatile
    - - Portable, battery powered
    - - Can process large amounts of data, have large backup capacities, expensive and require technical expertise, able to "hot-swap" components (taking out and maintaining components while still running)
    - - Portable
    - - A computer system with a dedicated and specfic purpose and is built into another device
    - - Works with quantum bits and isn't limited to two states (either 1 or 0)
    - - Can have multiple functions, portable, generic, adaptable. A downside to a hybrid device is that because it has multiple services, if it fails, then all of those services may fail as well.
  - - - Copper
        
        Cheap, sometimes suffers from interference, malleable, low bandwidth
      - Fibre optic
        
        Expensive, doesn't suffer from interference, fragile, higher bandwidth
    - - Bluetooth
      - Laser
      - Infrared
      - Microwave
        
        Has to be within line of sight
