Differences in Output Devices
Technology is ever changing around us, and one of these changes comes in the form of output devices. Can you imagine looking up something on the computer and not being able to print it out? How could we look at or listen to anything on our computer without a monitor and speakers? All of this is possible because of the advancement of output devices. Output devices use electronic or electromechanical equipment, such as printers, video displays, or speakers, to present data from a computer to a user in the form of text, images, sounds, or other media (Farlex). Output devices have made our lives so much more convenient, and allow us to receive the information we desire much more readily.
One of the most common output devices is a printer. A printer is an output device that produces text and graphics on a physical medium such as paper (COM 9). There are a wide variety of printers to choose from including impact, nonimpact, and photo printers. Each comes with their own set of pros and cons, and deciding which one works best for you all depends on what features are most important to you.
One type of impact printer is the dot-matrix printer, which prints characters and illustrations by striking pins against an ink ribbon. The pins form closely spaced dots to shape the desired character. The negatives of dot-matrix printers are they are quite expensive, do not produce high quality output, and are quite noisy. However, they can print to multi-page forms, while non-impact printers cannot (Escotal).
Two types of non-impact printers are ink-jet and laser printers. Ink-jet printers work by spraying ionized ink at a sheet of paper, than magnetized plates in the ink's path direct the ink onto the paper to create t...

3D printing has the potential to revolutionize the way we make almost everything. 3D printing was invented in the mid 1980s and was initially known as additive manufacturing. It consists of the fabrication of products through the use of printers which either employ lasers to burn materials (sintering) or place layer upon layer of material (known as stereolithography), eventually resulting in a finished item. Unlike the traditional manufacturing process, which involves milling, drilling, grinding or forging molded items to make the final product, 3D printing “forms” the product layer by layer. There are many different technological variants but almost every existing, 3D printing machine functions in a similar way: a 3D computer-aided engineering (CAD) file is sliced into a series of 2D planar sections and these are deposited by the printer, one above the other, to construct the part.
As we progress deeper into the digital era, we rely more and more on our electronic devices. Over the last decade, almost everyone who lives in a developed nation owns a cellphone and they are becoming an integral part of our life.
Smartphones are something we could not live without in our world today. You cannot leave the house without worrying where your smartphone is or even go to bed without making sure it is on the charger. Almost everyone you know has a smartphone, but technology has come a long way since the first smartphone was invented. Most people think of the company Apple Inc. when they hear the word smartphone, but believe it or not, they were not the first ones to invent it. In 1992, the International Business Machines Corporation (IBM) created the first mobile phone to incorporate PDA features that include receive faxes and emails, have a calculator, address book, appointment calendar, and a note pad (Sager, 2012). This device was called the Simone Personal
Throughout the years, it has become increasingly more efficient to access the media as more innovative and interactive mechanical devices are introduced. In fact, new technology has yet to be presented, further
In todays society the printing press has been innovated to colored printers. Without the
The advancement of cell phone technology in the last decade is truly astounding because back then most people’s cell phones had such limited capabilities. Cell phones or smart phones as they are also known today have so many advanced abilities it’s more like having a pocket sized computer in your grasp. We can
To put it more vividly, the printing process of a 3D printer is like making a melaleuca cake with various materials. And “the materials”, as the inventor of this technology Charles W. Hull once wrote, “include polymers, metals, ceramics, composites, food, probably other things, too”. So, imagine these materials can be melted like cream and stretched as thin as the hairline. The printer uses these lines to draw the outline of the object based on the inputted or scanned blueprint firstly and then overlaps the lines upon the previous frame just like decorating the cake with cream.
Johannes Gutenberg who was a German goldsmith, developed the printing press “in Mainz, Germany between 1446 and 1450” (Ditttmar, 1133). The printing press was made to print books, newspapers, and flyers. The machine was made from wood and was based off screw presses, that worked with inked movable type heads that allowed the paper to be quickly and efficiently pressed with letters. The type head was made by pouring a
With all the hype surrounding the iPod post its introduction into the electronics market, it should be of no surprise that iPod’s unmatched demand for such distinct music management tool would lead Apple to add iPod’s features to the most sold electronic device to date: the cell phone. Thus, you get a hybrid called the iPhone. This highly anticipated electronic trend setter without fault had numbers of people waiting in line at the Apple store in New York; iPod fans want to be among the first to explore some of the most innovative phone features to date. Among those features you will find a 3.5 inch touch screen (the largest of all smart phones), Wi-Fi connectivity, the most usage time of all smart phones, i.e. talk time, internet use, or video playback, and many more impressive characteristics. The iPhone has, thereby, revolutionized the cell phone industry to become a potential best designed and most admired phone of the decade.

Although, you can already go online and order a 3d printer that can fit on your desk it is still not very cost effective. Even the cheapest models can still run upwards of six hundred dollars, not including the operating cost of subscription to software and the material you are going to be printing in which, today is still mainly molten ABS plastic. There are also desktop laser cutters and CNC milling machines but still are not very cost effective, but the prices are slowly dropping as the technology is advanced, and this will lead to a whole new world full of inventors with ideas at very corner and for it to be made almost immediately. Some of the more expensive printers can use chocolate and other sweet foods that are easy to liquefy. Scientists have developed a printer that prints with human skin cells so to make new tissue and organs.
The printing press was invented in 1453. The movable printing technology was invented in China in 1040 but Johannes Gutenberg was able to perfect this technology by creating the Gutenberg printer in 1440. The printer was a movable type. A movable type was where individual blocks could be set up in order to print almost anything. Before this, wooden blocks, carved by hand were used to print things. These blocks would have consisted of what the individual wanted to print which would take an incredible amount of time. Gutenberg’s invention of a movable type printer established the ability for mass communication.
The idea was to improve 3d printer with special technology, a single printer, with multi material features, can transform from any 1D strand into 3d shape, 2d surface into 3d shape or morph from one 3d shape into another. The shape of 3d technology is basic mode for 4d. Objet Connex multi-material technology is an 3D printing important part of his work – and is being used extensively in this new process. The Connex multi material technology allows the researchers to program different material properties into each of the various particles of the designed geometry and harnesses the different water-absorbing properties of the materials to active the self-assembly process. With water as its activation energy, this technique promises new possibilities for embedding programmability and simple decision making into non-electronic based materials.
Print media is a rather commonly used term referring to the medium that disseminates printed matter. In everyday life we refer to print media as the industry associated with the printing and mostly with the distribution of news through a network of media, such as newspapers and journals. People also refer to print media simply with the term "press;" it's an intermediate communicative channel aiming at reaching a large number of people. Print media example Yellow pages, Newspapers, Business directories, Books, Magazines, posters.
Human beings are creative species. They have come up with great ideas and invented some wonderful tools since they have been on earth. From the time that someone threw a rock in the ground to make the first tool, to the introduction of the wheel, to the development of electricity and the Internet. These alterations, and many more have been made to provide us the modern life we are living today. There are many inventions that have changed the world dramatically. Historians suggest that the printing press was one of the most revolutionary inventions in the human history. The printing press was invented over five-hundred years ago and was the first step in transforming societal literacy. Around 1440, the printing press was invented by the German Johannes Gutenberg, who was the first to design a technique that has the ability to transform the ink from the movable type to paper. Basic development of the printing press was, the hand mold which is the process that enabled the production of metal movable types. Printing presses with this movable type mechanism increased the rates at which copies of books
