    A magnetic disc surface is divided into concentric rings known as ?                 ________

    Correct Answer
    Track
    Explanation
    A magnetic disc surface is divided into concentric rings known as tracks. Each track represents a circular path on the disc where data can be stored. The tracks are arranged one after another, forming concentric circles from the center of the disc to the outer edge. The data is stored in sectors within each track. By dividing the disc into tracks, it allows for efficient organization and retrieval of data on the magnetic disc surface.

    Each track is divided into parts known as                               ?

    Correct Answer
    Sectors
    Explanation
    In the context of tracks, sectors refer to the divisions or parts within each track. Sectors are used to organize and store data on a storage device such as a hard disk drive. Each sector typically contains a fixed amount of data, and the number of sectors on a track can vary depending on the storage device. By dividing the track into sectors, it becomes easier to locate and access specific data on the storage device.

    All tracks which can be accessed without moving the read/write heads are called                                 ?

    Correct Answer
    Cylinders
    Explanation
    All tracks which can be accessed without moving the read/write heads are called cylinders. In a disk storage system, a cylinder refers to a group of tracks that are located at the same position on different surfaces of the disk. When the read/write heads are positioned on one track of a cylinder, all the tracks in that cylinder can be accessed without moving the heads, resulting in faster data retrieval. Cylinders are used to organize and optimize data storage on disk drives.
