1. Display devices

1.1. A display device visually conveys text, graphics, and video information

1.2. A monitors is packaged as a seperate peripheral

1.2.1. LCD monitor (LCD screen) Liquid crytral display (LCD) uses a liquid compound to present information on a display device Active-matrix display Passive-matrix display The quality of LCD monitor depends on Resolution Response time Brightness Dot pitch Contrast ratio The graphics processing unit (GPU) controls the manipulation and display of graphics on a display device LCD mintors use a digital signal and should plug into a DVI port, and HDMI port, or a DisplayPort

1.2.2. Plasma monitor (Widescreen) Plasma monitor are display devices that use gas plasma technology and offer screen sizes up to 150 inches Televisions also are a good output device Require a converter if you are connecting your computer to an analog television

1.2.3. Video:SID:Size Matters

1.2.4. A CRT Monitor is a desktop monitor that contains a cathode-ray tube Have a much larger footprint than do LCD monitors

4. Printers

4.1. A printer prodoces text and graphic on a physical medium

4.1.1. Printed information is called a hard copy, or printout

4.1.2. Landscape or portrait orientation

4.2. Nonimpact printers

4.2.1. A Nonimpact printer forms characters and graphics on a piece of paper without actually striking the paper Ink-jet printer An Ink-jet printer forms characters and graphics by spraying tiny drops of liquid ink onto a piece of paper Photo printer A photo printer produces color photo-lab-quality pictures Laser printer High-Speed Black and white High-quality Color Multifunction peripheral (MFP) A multifunction peripheral (MFP) is a single device that prints, scans, copies, and in some cases, faxes Thermal printer A thermal printer generates images by pushing electrically heated pins against the heat-sensitive paper Mobile printer A mobile printer is a small, lightweight, battery-powered printer that allows a mobile user to print from a mobile device Label printer A label printer is a small printer that prints on adhesive-type material Postage printer A postage printer prints postage stamps Plotter Plotters are used to produce high-quality drawings Large-format printers Large-format printers create photo-realistic quality color prints on a larger scale

4.3. Impact printers

4.3.1. Impact printers form characters and graphics on a piece of paper by striking a mechanism against an inked ribbon that physically contacts the paper Dot-matrix printer A dot-matrix printer produces printed images when tiny wire pins on a print head mechanism strike an inked ribbon Line printer A line printer prints an entire line at a time

5. Speakers, Headphones, and Earbuds

5.1. An audio output device produces music, speech, or other sounds

5.1.1. Speakers Most computer users attach speckers to their computers to : Generate higher-quality sounds for playing games Interact with multimedia presentations Listen to music View movies Some speakers are specifically designed to play audio from a portable media player Wireless speakers

5.1.2. Headphones Headphones are speakers that cover your head or are placed outside of the ear

5.1.3. Earbuds Earbuds (also called earphones) rest inside the ear canel

5.1.4. Voice output Voice output occurs when you hear a person's voice or when the computer talks to you through the speaker Some Web sites dedicate themselves to providing voice output Often works with voice input VoIP uses voice output and voice input

6. Other Output Devices

6.1. Other output devices are available for specific uses and applications

6.1.1. Data projectors A data projector is a device that takes the text and images displaying on a computer screen and projects them on a larger screen Digital light processing (DLP) projector

6.1.2. Interactive whiteboards An interactive whiteboard is a touch-sensitive device, resembling a dry-erase board, that displays the image on a connected computer screen

6.1.3. Force-feedback game controllers Force-feedback sends resistance to the device in response to actions of the user

6.1.4. Tactile output Tactile output provides the user with a physical response from the device

7. Output Devices for Physically Challenged User
