2. An output device is any peripheral that receives data from a computer, usually for display, projection, or physical reproduction. For example, the image shows an inkjet printer, an output device that can make a hard copy of any information shown on your monitor. Another example of an output device is a computer monitor, which displays an image that is received from the computer. Monitors and printers are two of the most common output devices used with a computer.

3. 1)3D Printer Created by Charles Hull in 1984, the 3D printer is a printing device that creates a physical object from a digital model using materials such as metal alloys, polymers, or plastics. An object's design typically begins in a computer aided design (CAD) software system, where its blueprint is created. The blueprint is then sent from the CAD system to the printer in a file format known as a Stereolithography (STL), which is typically used in CAD systems to design 3D objects. The printer then reads the blueprint in cross-sections and begin the process of recreating the object just as it appears in the computer aided design. In the picture below is an example of a 3D printer called the Flash Forge.

4. 2)GPS Short for Global Positioning System, GPS is a network of satellites that helps users determine a location on Earth. The thought of GPS was conceived after the launch of Sputnik in 1957. In 1964, the TRANSIT system became operational on U.S. Polaris submarines and allowed for accurate positioning updates. Later this became available for commercial use in 1967. The picture shows an example of the GARMIN nuvi 350, a GPS used to find locations while driving.195719641967 On September 1, 1983 Soviet jets shot down a civilian Korean Air Lines Flight 007 flying from New York to Seoul and kill all 269 passengers and crew. As a result of this mistake, President Ronald Regan orders the U.S. military to make Global Positioning System (GPS) available for civilian use.1983 Today, with the right equipment or software, anyone can establish a connection to these satellites to establish his or her location within 50 to 100 feet.

5. 3)Headphones Sometimes referred to as earphones, headphones are a hardware device that either plugs into your computer (line out) or your speakers to privately listen to audio without disturbing anyone else. The picture is an example of a USB headset from Logitech with a microphone and a popular solution for computer gaming.line outspeakersUSBheadsetLogitech

6. 4)Monitor 1. Alternatively referred to as a video display terminal (VDT) and video display unit (VDU), a monitor encompasses a display screen for video images and casing that holds it. In its most common usage, monitor refers only to devices that contain no electronic equipment other than what is essentially needed to display and adjust the characteristics of an image. Like most early TVs, the early computer monitor's were comprised of a CRT (Cathode Ray Tube) and a fluorescent screen. Today, all monitors are created using flat panel display technology, like that shown in the image.CRTflat panel display Why is a monitor an output device? A monitor is only used to display (output) information from a computer and provides no source of input. Because a typical monitor sends no information back to the computer it is an output device.outputinputoutput device

7. 5)Plotter A plotter is a computer hardware device much like a printer that is used for printing vector graphics. Instead of toner, plotters use a pen, pencil, marker, or another writing tool to draw multiple, continuous lines onto paper rather than a series of dots like a traditional printer. Though once widely used for computer-aided design, these devices have more or less been phased out by wide-format printers. Plotters are used to produce a hard copy of schematics and other similar applications. vector graphicstonercomputer-aided designhard copy Advantages of plotters Plotters can work on very large sheets of paper while maintaining high resolution. They can print on a wide variety of flat materials including plywood, aluminum, sheet steel, cardboard, and plastic. Plotters allow the same pattern to be drawn thousands of time without any image degradation. Disadvantages Plotters are quite large when compared to a traditional printer. Plotters are also much more expensive than a traditional printer.

8. 6)Printer A printer is an external hardware output device responsible for taking electronic data stored on a computer or computing device and generating a hard copy of that data. Printers are one of the most commonly used peripherals on computers and are commonly used to print text and photos. The picture to the right is an example of a computer printer, the Lexmark Z605 Inkjet printer.externalhardwareoutputhard copyLexmarkInkjet Types of printers Below is a list of all the different types of computer printers.

9. History of the printer The first mechanical printer was invented by Charles Babbage, for use with the Difference Engine, which Babbage developed in 1822. Babbage's printer utilized metal rods with printed characters on each rod to print text on rolls of paper that were fed through the device.Charles Babbage Difference Engine While inkjet printers started being developed in the late 1950s, it wasn't until the late 1970s that inkjet printers were able to reproduce good quality digital images. These better quality inkjet printers were developed by multiple companies, including Canon, Epson, and Hewlett-Packard.Canon EpsonHewlett-Packard In the early 1970s, Gary Starkweather invented the laser printer while working at Xerox. He modified a Xerox 7000 copier to essentially be a laser printer, by having a laser output electronic data onto paper. However, it wasn't until 1984 that laser printers became more widely and economically available when Hewlett-Packard introduced the first low-cost laser printer, the HP LaserJet. The following year, Apple introduced the Apple LaserWriter laser printer, adding the PostScript technology to the printer market.Gary StarkweatherXeroxPostScript

10. 7)Projector Often no larger than a toaster and only weighing a few pounds, a projector is an output device that can take images generated by a computer and reproduce them on a large, flat (usually lightly colored) surface. For example, projectors are used in meetings to help ensure that all participants can view the information being presented. The picture is that of a ViewSonic projector.output deviceViewSonic

11. 8)Sound Card Alternatively referred to as an audio output device, sound board, or audio card. A sound card is an expansion card or IC for producing sound on a computer that can be heard through speakers or headphones. Although the computer does not need a sound device to function, they are included on every machine in one form or another, either in an expansion slot (sound card) or on the motherboard (onboard).expansion cardICspeakersheadphonesexpansion slotmotherboardonboard Sound card connections The picture is an example of a sound card audio ports or audio jacks on the back of your computer, associated colors, and the connector symbols.

12. 9)Speaker 1.A speaker is a term used to describe the user who is giving vocal commands to a software program. software 2. A hardware device connected to a computer's sound card that outputs sound generated by the computer. The picture shows the Altec Lansing VS2221 speakers with subwoofer and resemble what most computer speakers look like today.hardwaresound cardoutputsAltec Lansing subwoofer When computers were originally released, they had on-board speakers that generated a series of different tones and beeps. As multimedia and games became popular, higher quality computer speakers began to be released that required additional power. Because computer sound cards are not powerful enough to power a nice set of speakers, today's speakers are self-powered, relatively small in size, and contain magnetic shielding.on-board Rating a speaker Speakers are rated in Frequency response, Total Harmonic Distortion, and Watts. The Frequency response is the rate of measurement of the highs and lows of the sounds the speaker produces. Total Harmonic Distortion (THD) is the amount of distortion created by amplifying the signal. The Watts is the amount of amplification available for the speakers.

13. 10)SGD Short for speech-generating device, an SGD, is an electronic output device that is used to help individuals with severe speech impairments or other issues that result in difficulty in communicating. For example, SGDs can be utilized by those who have Lou Gehrig's disease (such as astrophysicist Steven Hawking, shown right) to supplement or replace speech or writing for them. Speech-generating devices also find use with children who are suspected of having speech deficiencies.output deviceSteven Hawking How do they work? Although SGDs vary in their design, most consist of several pages of words or symbols on a touch screen that the user may choose. As the individual makes their choices, suggestions are made for the next symbol or word based on what they might want to say. Additionally, the communicator can navigate the various pages manually if the predictive system fails. Most speech-generating can produce electronic voice output by utilizing either speech synthesis or via digital recordings of someone speaking.speech synthesis

14. 11)TV Short for television a TV or telly is an electronics device that receives a visual and audible signal and plays it to the viewer. Although debated, the TV is often credited as being invented by Vladimir Zworykin a Russian-born American who worked for Westinghouse, and Philo Taylor Farnsworth, a boy in Beaver City, Utah. Vladimir held the patent for the TV, but it was Farnsworth who was the first person to first successfully transmit a TV signal on September 7, 1927. The picture of the Panasonic TH-58PZ750U is a good example of a television.Philo Taylor Farnsworth1927Panasonic

15. 12)Video card Alternatively known as a display adapter, graphics card, video adapter, video board, or video controller, a video card is an IC or internal board that creates a picture on a display.
