Deletion refers to the process of removing data or information from a system, document, or database. This can occur in various contexts, such as when a user deletes a file from their computer or when a database administrator removes outdated records. Deletion can be temporary, allowing for recovery, or permanent, making it impossible to retrieve the removed data. In digital environments, deletion often involves sending files to a recycle bin or trash, where they can be restored if needed. However, once emptied, the data may be irretrievable, highlighting the importance of careful data management and backup strategies to prevent accidental loss.
