  • The contents of memory are lost when computer turns off.
    • But the content of storage, hard disk, memory are not lost when computer turns off.
  • CD, RAM, DVD- ROM- are secondary storage device. (but floppy is not.)
  • When you save to Secondary storage device- your data will remain intact even when the computer is turned off.
  • The difference between memory and storage is that memory is TEMPORARY and storage is PERMANENT.
  • Floopy disk has the smallest storage capacity.
  • Hard drive is the primary device that a computer uses to store information.
  • Storage unit is the place where computer stores programs and data.
