- 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.
- 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.
