WHAT IS A HARD DRIVE

 Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
A sector is
 A a pie shape section on the disk B a concentric circle on the disk C a group of platters D the mechanism that adds data to the disk
Explanation:

Detailed explanation-1: -A sector is said to be a part of a circle made of the arc of the circle along with its two radii. It is a portion of the circle formed by a portion of the circumference (arc) and radii of the circle at both endpoints of the arc. The shape of a sector of a circle can be compared with a slice of pizza or a pie.

Detailed explanation-2: -A sector is the smallest physical storage unit on the disk, and on most file systems it is fixed at 512 bytes in size. A cluster can consist of one or more consecutive sectors – commonly, a cluster will have four or eight sectors.

Detailed explanation-3: -A sector is a pie-shaped section, braking the tracks into arcs. A cluster is the smallest unit of disk space that stores data and information.

Detailed explanation-4: -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-5: -A disk sector is the part of a hard drive that is used to store data. A mathematical sector is part of a circle that can be visualized as a slice of pie. It consists of a wedge that extends out from the center to the edge of the circle, with two sides to form the shape of a pie slice.
