The correct answer is: B. Surface
A cylinder is a set of tracks on all the platters that are the same distance from the spindle. A track is a circular path on a disk where data is stored. A surface is one of the flat sides of a disk platter. A hib is a hidden sector on a disk that is used by the operating system.
A cylinder is a logical construct that is used to organize data on a disk. It is a set of tracks that are all the same distance from the spindle. This means that all of the data on a cylinder can be accessed without having to move the head arm. This makes cylinders a very efficient way to store data.
A track is a physical construct that is used to store data on a disk. It is a circular path on a disk platter. Tracks are arranged in concentric circles, with the outermost track being the largest and the innermost track being the smallest. The data on a track is stored in sectors.
A surface is one of the flat sides of a disk platter. A disk platter has two surfaces, one on the top and one on the bottom. The data on a surface is stored in tracks.
A hib is a hidden sector on a disk that is used by the operating system. It is used to store information about the disk, such as the disk’s geometry and the location of the partition table.
