deleted
Yes, I am wondering about how digital data can be deleted permanently.
Ah, I see. Well, when a file is deleted on a computer or other digital device, it's not actually removed completely. Instead, the space it was taking up on the hard drive is marked as available for new data to be written on top of it. But there are methods of permanently deleting data, such as overwriting it multiple times with new data or using specialized software that can wipe the hard drive.
