Let's test your knowledge and reasoning skill... Is (computer) FILE (a FILE is stored on a hard drive.) deletion a PHYSICAL or CHEMICAL change?
What about CD ROM and DVD ROM burning, and even erasing texts on a paper?

For the answer and (not so well) explaination, ROT13 this.

It's neither.


When a hard drive writes a file, it rearranges the electrons on a platter in the drive. If there's an electron there, it's a one. If not, it's a 0. Because this deals with electrons, the change is electromagnetic.


And if you think otherwise: Screw you. I'm going to school for this crap unlike you. So stfu and learn from your superiors.(me)

Not sure the different between the two, as far as I know:

When a file is deleted it is erased from the partition's index of files (which usually results in a change of south and north facing magnets on the hard disk, but far fewer if the space of the file was completely set to south). When new space needs to be made, it is over written in that part of the hard drive. A hard drive is a series of north or south facing magnets, very small of course.

electron ppl you fail its magnetic as for dvd/cds there really burned but into the foil/label

your ram stores electrons and it has to be refreshed 100+ a second

He's talking about hard drives.


Besides DVDs are written on by burning the surface of the reflective side. Because the laser does not bounce back, its registered as a 0.
