Detailed explanation-1: -In computer disk storage, a sector is a subdivision of a track on a magnetic disk or optical disc. Each sector stores a fixed amount of user-accessible data, traditionally 512 bytes for hard disk drives (HDDs) and 2048 bytes for CD-ROMs and DVD-ROMs.
Detailed explanation-2: -A sector is the smallest physical storage unit on the disk. The data size of a sector is always a power of two, and is almost always 512 bytes. Each track has the same number of sectors, which means that the sectors are packed much closer together on tracks near the center of the disk.
Detailed explanation-3: -Detailed Solution. The correct answer is cylinder > Track > sector .
Detailed explanation-4: -Hard disk drive components include the spindle, disk platter, actuator, actuator arm and read/write head.
Detailed explanation-5: -To help store and retrieve the data from the platter, data is stored in tracks, sectors, and cylinders on each platter. Pictured above is the inside of a hard drive, with its platter indicated.
