     • CD
     • Charateristics
       • Speed 1,400,000 bytes per sound

2. solid state

   • it is made of microchips
   • it dermines if it is a one or zero
   • Solid state storage is a computer media. It stores data electronically instead of magnetically as a spinning hard drive disk.
   • example devices
     • SSD
     • USB memory stick
   • Main advantages
     • ore compact than hard disk drives
     • Faster than hard disk drives
     • Is completely quiet
     • Takes minimal power
     • More durable

3. magnetic

   • Head moves across and changes magnetised that part of the medium is
   • one level of magnetism will be o1 and another will be zero.
   • Example devices
     • Floppy hard drive
     • Hard disk drive
     • magnetic tape
   • Advatages
     • longer lifespan
     • less online threats hacking or spam
     • Portable like USB
   • Disavantages
     • Large Data Storage
