How does it physically “forget” whatever coded form it held my word document in for example?
In: Technology
A computer doesn’t truly “forget” data until it gets overwritten by new data.
When you delete or uninstall something, the computer doesn’t really get rid of the data. It just forgets where the data is. So you won’t see it anymore and you can’t tell the computer to find it because it doesn’t even know where to look.
This can be important for data security. When you get rid of a computer, any sensitive information that was never actually written over may still be accessible by a snoop with the tools to read the forgotten data rather than what the operating system thinks is there.
