What describes the process of dividing data into blocks and spreading it across disks for higher performance?

  1. Mirroring

  2. Striping

  3. Parity

  4. Spanning

The correct answer is: Striping

Striping is the process of dividing data into blocks and spreading it across multiple disks. This is done in order to improve performance and speed up data access. Mirroring (A) is a backup strategy where data is duplicated on two or more disks. Parity (C) is a method of error checking to ensure data integrity. Spanning (D) is a method of combining multiple disks to appear as a single logical drive. However, striping is the most appropriate answer for the given question as it specifically refers to the process of dividing data into blocks and spreading it across disks for higher performance.
