A hardware device, such as a hard disk or floppy disk, used to record and store data.

Here are some examples of storage devices in the computer.

                         They are plastic square disks, usually with a silver or black sliding piece going across the top. These disks come in a variety of colors and they hold about 144 million bytes. (Bytes are characters, symbols and letters).

2.)A DVD – R Disc (Digital Video Recordable)  

                  These discs hold the space of about 4.7 GB and are used to record movies on.

3.)CD + RW Disc (Compact Disc Rewriteable)

             This disc looks like a regular CD. The only difference is that you can write on this disc and erase it as many times as you want. It works just like a floppy disk or a zip disk. A CD + RW disc holds about 650 MB.

4.)Flash Drive 

               This a storage device that comes in many colors and has a stick shape to it. They are very small in size, but they can hold anywhere between 256 MB and 3 GB of material on them.

 

5.)Removable Hard Drive

                This is a disk drive in which a plastic or metal case surrounds the hard drive. It can be inserted and removed just like a floppy disk. It holds about 2 GB of data.
