When stuff gets deleted off your phone or emptied from your recycle bin on your pc.... where does it go??!


No I'm serious.... how is it you can restore some stuff after it's been re-formatted or whatever? it must stay there somewhere..... BUT WHERE??

its still stored on your hard drive until you install something that takes its place . You can get these files back only by using dos if you have not installed anything to take its place ONLY.

your hard drive just "remembers" it but it strangely uses less memory as far as i know.

Nothing you delete is ever truely wiped it just uses a TINY nano sized piece of information.

Its still technically there. Once you create/move enough files then eventually it gets overwritten though. Thats why its much harder to recover deleted files when you wait to long.

Does data ever have physical mass?

Read her name, it irritates me when it's damn well obvious what someone's gender is and everyone is too ignorant to work it out.

I'm fairly sure it stays on the computer as data that is okay to overwrite, and then new stuff you put on it replaces the old data. But I'm not an expert by any means of the imagination.
The will to neither strive nor cry,
The power to feel with others give.
Calm, calm me more; nor let me die

Yeah I thought that when you saved something it was written to your hard drive/phone memory.... so doesn't that mean you can only overwrite so many times before it gets all confused and starts splicing in bits of old deleted stuff?

EDIT: actually I think I'm more easily confused than my computer

But the record or binary value or whatever...must exist somewhere on the hard disc

So is it something actually exists?

You don't really think an unused 60gb hard drive has a lower mass than one that's 80% full... Do you?

lol, it would be funny if data accumulated physical mass. But I'm pretty sure digital data can't actually weigh anything.

When you empty your recycle bin, you're not deleting anything. You're fundamentally making your computer "forget" where the file is.

Yeah but that analogy is like.... that the hard drive is like paper that gets written on and rubbed out and re-written on.... eventually you can't write on it anymore.... If the hard drive got too heavy with info wouldnt' it be impossible to remove and make the computer die?

Double post. Maybe you're right - maybe data takes the form of gas, stemming from the heat from the CPU.

Ok I have another stupid question...

If the universe is expanding... What's it expanding into?

Empty space...

Not to be confused with...space...

Back in the day when i was at school I asked my physics teacher. He said into a vacuum. I asked what existed outside the vacuum and he said it went on for all eternity. However this was a CofE school so I doubt he knew anything other than 'outside the bubble of the universe is where god lives'

The idea of eternity is too much for my tiny brain to fathom..... The universe must be going somewhere! which means there is somewhere for it to go! which means the universe is not eternity because it is not everything! because there is something else, that it's moving into!!

Its on the hard drive still, but the physical part of the hard drive that the data is on is treated as blank. So in time, as you get more files it'll eventually get written over.

And data on hard drives has no mass. It's magnetic, where the magnetism corresponds to the 0s and 1s of the data. In fact, for any digital media the data does not actually occupy mass. It's just manipulation of the physical material that corresponds to the data. Like the pits on cds and the magnetism in floppy disks or hard drives.

basically what happens when you delete data from your PC's hard-drive is you just de-register it from the Operating System's File Allocation Table. When you write data to a hard disk, the computer just randomly finds the nearest blank spot on the hard drive and writes it there, and then remembers where that file is on a FAT (File Allocation Table). So all pieces of information on your hard disk are actually documented. This is the same for FAT16 (DOS), FAT32 (Windows 95 to ME), NTFS (Windows 2000 to Windows XP) and xt2-xt3 (Linux etc).

When you delete something from your computer, all you're doing is just telling the computer to forget where that piece of data is on your computer's hard drive and treat it like blank space. Smart programs can document the changes to data and remember where those pieces of data are indefinately (UNLIKE MAC) so you can RECOVER them, even if you have deleted them from your Recycle Bin.

Magnetically, your data is still there, but if you've done anything else since you deleted something from your Recycle Bin, your computer may have unfortunately written over the top of it!

Computer Data does have "physical mass" to it, I am just to drunk and hungover to explain the whole bit, if you reformat a hard drive nothing can be saved from it, there's no tiny space the hard drive uses to save something important, well, gonna go make some food (4:45 in the morning) lol

it has to have mass. everything does. there has to medium for its magnetism (iron). You cant magnetise nothing.

So, hypothetically, if I had kiddie porn on my computer (if) and deleted it, and emptied the recycle bin because the police were suspicious (say), it's actually still there?

Here's a new question: what's the quickest way to completely destroy a hard drive? Fire?
#36
it is still on your temorary drive for a bit but depending on how often you use your computer it will eventually go away.
#38
Data having physical mass question:

Suppose when you write data it's like drawing with a pencil. There is no real weight difference in the paper before and after it was drew on. Maybe a hard-drive acts this way?
#39
A harddisk is made up of several feromagnetic disks on top of each other, and divided into very numerous and small regions, each one capable of storing one bit. When a special arm passes over those small regions it either reads the polarity of the region (and the two possible polarities are interpreted as 1 or 0 by the harddisk's controller), or it can change polarity according to what the controller receives as input.

As for computer data, it only exists "logically", as 1's and 0's represented by two different voltage levels in the computer's circuitry. When, say, an input pin of a processor is set at the higher voltage level, the processor interprets it as a logical 1, and the lower voltage level as a 0.

A computer is basically one big complicated voltage switcher. And software stored in a memory has no mass and doesn't exist physically, it's a way for the computer aided human mind to express something.
Dear God, do you actually answer prayers?

Yes, but only in a way indistinguishable from random luck or the result of your own efforts.

YES but if its being contained it's being contained in something. What exists outside the container? Because what's inside it is meant to be everything?

CONFUSING!
