The error-correction techniques in RAID disks uses the method of (A) spatial redundancy (B) temporal redundancy (C) information redundancy (D) physical redundancy (E) All of the above

Answer: (C) Information Redundancy

Explanation: RAID (Redundant array of independent) disks are the disk that are arrangement of the hard drive and are connected in a way to make the performance speed faster and secured of disk storage of a computer. Being a highly secured system, then also there are chances of error due to the automatic activation. So, whenever this situation arise, RAID activates the data present in the disk of RAID and thus the information redundancy is carried out.
