Q6. What are the circumstances in which you can lose your data?
Ans. Circumstances in which data can be lost are:
- Hardware failure: Refers to the failure of computer hardware devices due to their limited lifetime. Hardware failures, such as corruption of the hard disk drive, may lead to data loss. Therefore, during hardware failure, the lost data can be restored from a backup.
- Accidental deletion or modification of data: Refers to the threat of accidental deletion or modification of data. For example, you may accidentally delete an important file from your computer. In such a case, the deleted file can be restored from a backup.
- Restoration of the old version of a file: Regular backups allow you to recover the old information. If you need to access an old version of a modified file, you can do so if regular backups have been performed on your computer data.
- Unauthorized deletion or modification of data: Regular backups allow you to restore data that has been deleted or modified by an unauthorized user.
