Five examples of storage devices(ASSIGNMENT)

Hard disk platters and head.jpghard disk drive[2] (HDD) is a non-volatilerandom access device for digital data. It features rotating rigid platters on a motor-driven spindle within a protective enclosure. Data is magnetically read and written on the platter by read/write heads that float on a film of air above the platters.

CD-ROM (pronounced /ˌsiːˌdiːˈrɒm/, an acronym of "compact disc read-only memory") is a pre-pressedcompact disc that contains data accessible to, but not writable by, a computer for data storage and music playback. The 1985 “Yellow Book” standard developed bySony and Philips adapted the format to hold any form ofbinary data.[2]
floppy disk is a data storage medium that is composed of a disk of thin, flexible ("floppy") magnetic storagemedium sealed in a square or rectangular plastic carrier lined with fabric that removes dust particles.
CD-RW (Compact Disc-ReWritable) is a ReWritableoptical disc for reWriting. Known as CD-Writable (CD-RW) during its development, CD-RW was introduced in 1997, and was preceded by the CD-MO, which was never commercially released, in 1990.

Five output devices(ASSIGNMENT)

Monitor - A monitor is the screen on which words, numbers, and graphics can be seem.  The monitor is the most common output device.
Printer - A printer prints whatever is on the monitor onto paper.  Printers can print words, numbers, or pictures.
Speaker - A speaker gives you sound output from your computer.  Some speakers are built into the computer and some are separate.
Disk Drives - A disk drive is used to record information from the computer onto a floppy disk or CD.
Floppy Disk - A floppy disk is used to record information on.  The information is stored on the floppy disk and can be used later or used on another computer.

Five input devices(ASSIGNMENT)

Camera - most cameras like this are used during live conversations.  The camera transmits a picture from one computer to another, or can be used to record a short video.


Compact Disc (CD) - CDs store information.  The CD can then be put into another computer, and the information can be opened and added or used on the second computer. 
Note:  A CD-R or CD-RW can also be used as an OUTPUT device.
Keyboard - The keyboard is a way to input letters or numbers into different applications or programs.  A keyboard also has special keys that help operate the computer.

Mouse - The mouse is used to open and close files, navigate web sites, and click on a lot of commands (to tell the computer what to do) when using different applications.
Digital Camera - A digital camera can be used to take pictures.  It can be hooked up to a computer to transfer the pictures from the camera to the computer.  Some digital cameras hold a floppy disk, and the floppy disk can be taken out of the camera and put directly into the computer.
