Why is unsaved work lost in a power cut?
Short answer. It was in RAM, which is volatile.
Where do saved files stay?
In storage.
RAM versus storage
| Memory | Power off | Example |
|---|---|---|
| RAM | erased | open work |
| ROM | kept | startup code |
| Storage | kept | saved files |
Remember
| RAM forgets when power goes |
| Storage keeps saved files |
| Save your work often |
Power cut, file not saved. Why is it gone? Here is why. Unsaved work sits in RAM. RAM is volatile, so power off erases it. ROM and storage keep data safely. So remember. RAM forgets. Storage keeps. Save often.
