what is wipe data

Data wiping is the process of removing data from a read/write medium so that it can no longer be read. It is a software-based method of data sanitization that aims to completely destroy all electronic data residing on a hard disk drive or other digital media by overwriting data onto all sectors of the device in an irreversible process. Data wiping is also known as data clearing, data destruction, or data wiping. When data is wiped, it is rendered unreadable and unrecoverable, unlike when data is erased, which can often be recovered by anyone with the appropriate know-how or recovery software. Wiping data/factory reset deletes all applications, app data, and information (documents, videos, images, music, etc.) stored in the internal space of a device, making it required to perform a data backup operation before resetting the device to factory settings. Data wiping is typically conducted using an overwrite program that gets rid of a files original information by replacing it with other information.
