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

(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.

professionals can use many types of technology that can them. some examples are, computers (they research and can use for programs for data, they are also used for job applications, school work, and even to make new ideas), speedometers (can get data for unknown data), sometimes something as small as a pen (used for rough drafts, to insert data, and again job applications).
