Final answer: RAID 5 is the level of RAID also known as disk striping with parity.

Answer:

RAID 5 is the level of RAID also known as disk striping with parity. It is a method used to store the same data in different places on multiple hard disks to secure data in case of a failure.

Explanation: RAID 5 is a type of RAID configuration that uses disk striping with parity. RAID stands for Redundant Array of Independent Disks, and it is a technology that combines multiple disk drives into a single logical unit to improve performance, redundancy, or both. In RAID 5, data is striped across multiple drives, and parity information is also distributed across all the drives in the array.

Disk striping is a technique where data is divided into blocks and each block is written to a separate disk drive. This allows for data to be read and written in parallel, which can improve performance. Parity is additional data that is calculated from the other data in the array, and it is used to reconstruct the original data if one of the drives fails.

RAID 5 requires a minimum of three disk drives to operate, and it provides fault tolerance by enabling the array to continue functioning even if one drive fails. When a failed drive is replaced, the data can be rebuilt using the parity information stored on the other drives.

Overall, RAID 5 offers a good balance of performance and data protection, making it a popular choice for many organizations looking to ensure the safety and availability of their data.
