Program Plan Intro

Multiple disk storage systems:

The computers have limited size of main memory to store data. So most of the computers have additional memory devices called as mass storage or secondary storage systems such as magnetic disks, CDs, DVDs, magnetic tapes flash drives etc.

The multiple disk storage systems are the systems which unite many drives and are used to store the data. The multiple disk storage system is also called disk farms.

Cylinder in storage system:

The disk with the magnetic coating is used in the computer. The spinning disk is used to hold the data because read/write heads are placed above and below the disk that transverses a circle due to the spin of the disk called as track and theses track can contains more information.

The read/write heads move in unison and each time read/write heads change their position due to spin of the disk and because of this reposition of disk, there is a new set of tracks which is called as a cylinder.
