          Secondary Storage Device can also be explained as devices that can be used externally as memory. The computer requires the use of input and output channels to access the external memory. Secondary Storage Devices includes the following devices namely, CD, CD-R, D-RW, External Hard Disk, Hard Disk, DVD, Floppy Drive, Zip Drive, Magnetic Drive, Blu-Ray and Flash Memory, etc.                CDs normally have a capacity of 750mb to 800mb. DVD's (Digital Versatile Disc) capacity varies, for example, DVD Rom is available with following capacities 4.7GB, 8.5GB, 9.4GB and 17.0GB, DVD-R i.e. Write once DVD are available with following capacities 4.7GB, 8.5GB, and 9.4 GB, DVD RAM i.e. Rewritable DVD's has the following capacities1.46 GB, 2.6 GB, 5.2GB, 4.7GB, 9.4GB.

Any secondary storage system involves two physical parts: a peripheral device and an input/output medium. A disk drive and a tape drive are examples of peripheral devices; diskettes and magnetic tape cartridges are type of media. The drives write data and programs onto, and read them from the storage media. a medium must be situated on or inserted into a peripheral device for the CPU to process its contents. Peripheral storage devices can be internal or external .Internal devices such as diskette, hard-disk, and CD drives typically come installed and configured within the system unit when you buy a computer system. These devices can also be installed in empty bays in the system unit when necessary External devices are stand-alone pieces of hardware that connect via cables to ports on the system unit.

Internal devices bring the advantage of requiring no additional desk space, but external devices can more easily be shared between two or more computer systems. In most secondary storage systems, media must pass by read/write heads inside the peripheral devices for programs and data to be read from or written to the media. For instance, when you listen to music on a cassette or record it on your home stereo system, the tape passes by a head on the tape deck, which either plays or records music. Tapes and disks on computer systems work by similar principles.

For storing massive amount of information secondary storage devices are used. There are different storage devise used in system unit. These secondary devices are Hard Disk, Floppy Disk, CD-ROM, Tape Drive, Zip drive etc.

Hard disk is secondary storage device used to store data and programs permanently. We can change or erase the data from hard disk. It can store large amount of data for longer time. It is compulsory secondary storage device for the personal computers. CD-ROM stands for Compact Disk Read Only Memory. It is option and most popular storage device of the personal computers. Compact Disk (CD) capacity is measured in bytes and can store more than 750 million characters. Floppy disk is also optional device for personal computers. It is available in two sizes; 3.5 inches (store 1.5 million characters which is equal to 1.4 MB) and 5.25 inches (1.2 million characters).

Hard disk storage capacity is more than floppy disk and CD-ROM. Tape driver is like a tape recorder used to read from and write data onto tape cartridge. Zip drive is like a floppy drive but it can store a large amount of data. It is used to store data or information on the disk.
