Which term describes the permanent removal of data from a device using methods such as wiping software or degaussing?

• A. Data Wiping
• B. Data Backup
• C. Data Remanence
• D. Data Encoding

Answer: (A)

Permanent removal of data from a device is called data wiping. It means making sure the information can no longer be recovered, typically by overwriting the storage with new data patterns or by degaussing magnetic media. Wiping software directly overwrites the drive to erase the original bits, while degaussing uses a strong magnetic field to disrupt the stored data’s magnetic domains, making recovery extremely difficult or impossible. This approach is about sanitizing the device to prevent future access to the sensitive information.

Data backup is the act of creating copies, which is the opposite of removal. Data remanence refers to residual data that may linger after some erasure methods, highlighting a potential risk rather than the act of removing data. Data encoding is about converting data into a different format for storage or transmission, not removing it.
