HARDWARE

1. STORAGE

   • TYPE
     • MAGNETIC STORAGE
       • FUNCTION
         • All magnetic media use the same general process of a read/write head magnetizing material
       • EXAMPLE
         • floppy disks
         • magnetic recording tape
         • magnetic stripes
     • OPTICAL STORAGE
       • FUNCTION
         • . An optical storage device is written and read with a laser. It is strong and can handle temperature fluctuations much better than magnetic media
       • EXAMPLE
         • erasable optical cartridges
         • removable disk (RDX)
     • CLOUD STORAGE
       • FUNCTION

       • EXAMPLES
         • Dropbox
         • OpenDrive
     • SOLID STATE STORAGE
       • FUNCTION
         • a type of non-volatile computer storage that stores and retrieves digital information using only electronic circuits, without any involvement of moving mechanical parts
