Transcript of Computer Output Devices

Computer output devices are pieces of computer hardware that convert computer data into human-readable form. All of these are examples of output devices. Sound output, video output, printers, computer monitors, and display devices, are all output devices, and output devices have a promising future. What are they? Computer Output Devices Some examples are: Monitors, speakers, and graphics cards. Sound output is very important in a computer,
there are many different kinds of sound outputs:
2.1, 3.1, 5.1, and 7.1. If you don't have sound (speakers) you won't be able to hear anything that you are doing on the computer. Sound Output Video Output Speakers/Headphones Video output would be something like monitors, or graphics cards. Monitors take the computer data, and make it into human-readable form so you can see whats happening.

Graphics cards are dedicated to anything video wise. (i.e. graphics rendering in video games) Speakers, are a form of an output device. The speakers give you sound output, often speakers are integrated right into the computer, or a separated device. Headphones are also a form of an output device. Headphones are similar to speakers, but are meant for one person to listen to the sound. A computer monitor is an essential part to a computer, without it you would not be able to see or do anything. Monitors have evolved from old school tube monitors into HD flat screen monitors. Computer Monitors Printers Ink Jet Printers Laser Printers Use heat and pressure to bond particles of toner to

Printers are another form of output device The Future of Output When computers are connected to the printer they produce a permanent visual record of the output data in human readable form known as hard copy Ink-Jet and Laser printers are the most common This is the Oculus Rift. While technically this is an input/output device, its still pretty cool. A display device is any device that displays information in a visual form. Future Continued.. The Oculus Rift is a virtual reality headset that has a screen on the inside. It takes your head movements and uses it as the x and y axis for video games. But this is just the beginning. Eventually we'll be able to build super-computers the size of a watch. We'll just have to wait and see. Output is anything that comes out of a computer Output can appear in a variety of forms -- as binary numbers, as characters, as pictures, and as printed pages Segment Displays Most digital clocks, digital watches and pocket calculators have/are segment displays Have segments that go on and off to produce a different character Printers print text or illustrations on paper Display devices include but are not limited to, computer monitors, television sets and medical monitors! Sound Continued... The newest sound system is a 7.1 speaker setup consisting of 7 speakers and 1 subwoofer. In 7.1 there is a center speaker, a left and right, middle left and right, and a back left and right. With that in mind, it is true that monitors and tv's etc are display devices. But a display device is not a monitor or tv! The Thin Film Transistor Liquid Crystal Display (or TFT-LCD) is currently the display device most used in flat screen monitors, televisions etc.
The Cathode Ray Tube (CRT) was used in older monitors. Those huge bulky ones. The display device is actually within the item visually displaying information itself.
