Output Devices
Output Devices are the signals or data sent from a computer system and presented to the user in a suitable format. However though CD-ROM and DVDs are not output devices, those are considered to be storage devices.
Computer output devices can be organized into four simple categories, audio, graphics, text, and video. Audio is music, speech, or any other sound. Graphics are digital representations of non-text information such as drawings, charts, photographs, and animation. Text consists of letters, numbers, punctuation marks, or any other symbol that is used to create words, sentences, and paragraphs. Video consists of images played back at speeds to provide the appearance of full motion.
Without output devices this world would be back in time before there was any type of electronics. Output devices let us enjoy listening to music, watch movies, use the GPS on our smartphones when we get lost, and even let us use printers to make 3D models and produce braille on products for people that are blind. I honestly couldn’t think of how it must have been living in a world without all these technologies that make life that much simpler.

Types of output devices and what they do.
• 3D Printer - A person must first create a 3D image of the item they want printed using a software program from there the computers sends signals to the 3D printer which uses laser sintering, involves heating and solidifying granular material with a laser in a specific pattern for each slice before repeating over and over again with new layers.
• Braille embosser - A braille embosser is an impact printer that renders text as tactile braille cells.
• GPS - GPS works by sending signals to a satellite out in space and...

...o have existed, so I believe that the future will have many of computer output devices that will put these output devices to shame.
Learning about computer output devices was very interesting and I learned a lot about computers then I knew before. I think the future is going to have some very amazing devices that are going to blow these devices out of the water.

1. A device is a computer if it has an input device, central processing unit (CPU), internal memory, storage, and an output device.
...netheless it is still an advancement and one that historians should take note of for the future.
These devices are attached to the motherboard through different connections. The output devices like monitors and printers can be used by a file server to show different files or print hard copies of files. These devices take the data from the computer and put it into a format that users can read and understand. I would like to take a moment here and go over the different kinds of monitors that a person can use as an output device. The first is the regular CRT monitors are heavy and use a lot of electric power to display objects, but are preferred by graphical artist for the color rendition. Then there are the flat panel monitors, which can use liquid Crystal Display (LCD) or a plasma display. These displays use electronically at each pixel to control the color. The input devices like a keyboards and a mouse. These inputs take the movements from the users and turn it into data that the computer can understand. (Beach,
Printer – A printer is used to print different images from the computer that you want to, this could be important sop the user can print the image that they have created and they can scan it onto different hardware and make different items with this graphical image.
In present time, if we look closely around everything we visualize: the clothes we wear, the colors of the room in which we find ourselves, the traffic signs, the television etc., everything around us had a process in which made the picture the sign the logo, Film, video, That where Graphic designs, photography, printmaking, computer-aided design and digital art come into play. Printmaking is a mechanical method to reproduce texts and images on paper, cloth or other materials. In its classic form, it consists of applying an ink, usually oily, on metal pieces to transfer it to a paper by pressure. There is a couple of different technique when it comes to printmaking like relief, intaglio, lithography, and serigraphy which matrices included wood
This Essay will discuss Codecs; it will explain the definition of codecs and their functions and include a brief history on digital signals, equipment and standards. It will also discuss compression and compression formats such as Lossless and Lossy and files such as FLAC and ALAC
heavily relying on it every day. We would feel painful if no digital devices. In the past, we are
The two main ways printers work is either impact or nonimpact. Impact printers have a device that touches the paper and then creates an image while nonimpact does not touch the paper. The type we use most often in our homes is the nonimpact printers; these include the ink-jet and laser printers. The ink-jet printer drops ink from a nozzle onto the paper. The laser printer is a bit more complicated because it uses toner, static electricity, and heat to get the ink where you want it on the paper. This is nice though because it decreases the drying time that may cause ink to smear, especially when you are printing pictures. (Tyson)
Almost every device has some type of computer in it. Whether it is a cell phone, a calculator, or a vending machine. Even things that we take for granted most cars since the 1980’s have a computer in it or a pacemaker. All of the advancements in computers and technology have led up to the 21st century in which “the greatest advances in computer technology will occur…” Mainly in areas such as “hardware, software, communications and networks, mobile and wireless connectivity, and robotics.”
Without technology we wouldn’t have gotten this far, we wouldn’t have a simple and convenient life or even met new people from around the world. Technology is what everyone needs for a better life, but in order for it to benefit, we need to use it in the correct manner and not exploit it.
After the telegraphy came the telephone, and the radio, and then the television: where messages had motion pictures attached to it. The developments of these five important tools of communication played a role in evolving technology to where we are
People in the present society have turned from the use of the old means of communication to the more advanced and technological ways of communicating. Technology has made it easier for people to communicate in a faster, efficient, and cost saving means through the introduction of the communication channels. The world has turned out to be the centre for technology with different technologies emerging daily as the people continue to develop from time to time to cope with the growing technology. The benefits of adopting the communication technology are explained in this article which shows why people do not function without technology.
Technology has gone from colorless block televisions and giant computer to computers you could fit on your fingertip and televisions that are flat and 3 Dimensional. Now they even are making holograms and televisions that go into an even better quality of graphics. There are thousands
Now for computers in the schools, I feel we will soon have no books and all work will be done on computers. Even homework will be done on the internet and e-mailed to the teacher. Children will be taught about computers at a younger and younger age. This in turn will make the younger generations more and more skilled in electronics and understanding how they work. This will have a very large impact on they way projects and or work is viewed.
Input is really important for the computer. Through this device, users are allows to enter data or instructions into a computer. It changed something on the screen through the response. There are many kinds of input device for users to select depending on their application to get the result they want. There are many input technologies, for example, keyboard, pointing device, trackball, touch screen, touchpads and audio input. These devices can help users to connect with computer system directly.
