Tracks are divided into invisible wedge-shaped sections called
A sectors
B cylinders
C platters
D bits
The correct answer and explanation is:
The correct answer is A) sectors.
In the context of hard disk drives (HDDs) and other types of magnetic storage devices, the storage medium is divided into concentric tracks that are further subdivided into smaller, invisible sections. These sections are called sectors. Each sector is the smallest unit of data storage on a disk and typically holds 512 bytes or 4,096 bytes (for modern systems).
When a disk is formatted, it is organized into tracks, which are circular paths on the surface of the disk. These tracks are then divided into sectors. The disk’s read/write head accesses the data in these sectors to read or write information. A sector can hold a fixed amount of data, and when data is written to the disk, it is stored in these small sections.
In addition to sectors, the disk has cylinders, which are imaginary vertical stacks of tracks. These cylinders allow the read/write head to move up and down the disk to access different tracks quickly without having to reposition the arm too much.
A platter is the physical disk on which the data is stored. Each platter is divided into multiple tracks and sectors. Hard drives usually have several platters stacked on top of each other, and the data is accessed across all of them.
Finally, bits represent the smallest unit of data in computing. A bit is a binary digit, either 0 or 1, and multiple bits combine to form the data stored in sectors. Therefore, the concept of a sector is integral to the organization and management of storage on the disk.
