Data loss

Data loss is when you lose important information or data. It usually happens when something bad happens to your computer or phone, like it gets broken, or when you accidentally delete a file. When data is lost, it usually can't be recovered. So it is important to back up your data (make a copy of it and put it somewhere safe, like in a cloud or on a separate hard drive). That way if something happens to your computer or phone, you still have a copy and won't lose any information.
