170 views

Deletion refers to the process of permanently removing data from a storage device or system. It works by unlinking the reference to the data, making it invisible to users and marking its storage space as available for new data. However, until new data overwrites the original, it may still be recoverable with specialized software. Secure deletion methods are essential for sensitive information, ensuring it cannot be retrieved.
