Digital Camera
About a year ago I purchased my very first digital camera. The digital camera is by far very different from the analog camera that I used to have when I was a kid. The analog camera used film that you had to advance to take the next picture and you also had to worry about the flash. The digital camera captures the photograph and saves it on a digital memory card. The biggest difference from the digital camera and the analog camera is that you can see your picture immediately after taking the picture. The analog camera you had to wait until you developed the film to see the results.
“The first recorded attempt at building a digital camera was in 1975 by Steven Sasson, an engineer at Eastman Kodak. It used the then-new solid-state CCD (charged coupled device) image sensor chips developed by Fairchild Semiconductor in 1973. The camera weighed 8 pounds (3.6 kg) recorded black and white images to a cassette tape, had a resolution of 0.01 megapixels (10,000 pixels), and took 23 seconds to capture its first image. This prototype was a technical exercise not intended for production.” Digital cameras have become very compact and stylish, since the prototype.
In the mid 1980’s Kodak was the first to develop a 5x7-inch digital photo quality print from the megapixel sensor, capable of recording 1.4 million pixels. They also produced the Photo CD System and released the first professional digital cameras for professional photographers. The Digital camera became available to the common consumer in 1994 that worked with a home computer connected by a cable.
Several other companies were also getting on the digital bandwagon with Kodak were Apple and Olympus. Apple developed the “Quick Take 100, a color digital camera with a 640 x 480 pixel CCD, and a fixed-focused 50mm lens. The Quick Take 100 could only store 8 images on its internal memory.”…...

Digital Media

...Digital Media: A Better Way to Learn Educators and parents have legitimate concerns about the effects of the Digital Age on learning. Digital media has changed dramatically since the development of the Internet and improvement of wireless technology. John Palfrey, Professor of Law and Urs Gasser, Executive Director of the Berkman Center for Internet and Society, both employed by the prestigious Harvard Law School, have written about how the world has been reshaped because of this new digital world in Born Digital. They found that this period “is the most rapid period of technological transformation ever, at least, when it comes to information” (3). This transformation of digital media over the last twenty-five years and the introduction of tools like the iPad create a clutter of information that threaten the ability to think deeply and concentrate, which has made the current educational system obsolete and ineffective. This same technology can be utilized to create the school of the future, by improving learning in the Digital Age. Digital natives, ”born after 1980,” do not know the world without the Internet, cell phones, computers, tablets and everything else that networked digital technology has provided (Palfrey 1). They “study, work, write and interact with each other in ways that are very different from the ways” their parents and grandparents grew up. (Palfrey 2). Palfrey and Gasser found that digital natives are comfortable with this new technology and......

Digital Transmition

...1 Introduction to Digital Data Transmission 1.1 INTRODUCTION This book is concerned with the transmission of information by electrical means using digital communication techniques. Information may be transmitted from one point to another using either digital or analog communication systems. In a digital communication system, the information is processed so that it can be represented by a sequence of discrete messages as shown in Figure 1–1. The digital source in Figure 1–1 may be the result of sampling and quantizing an analog source such as speech, or it may represent a naturally digital source such as an electronic mail file. In either case, each message is one of a finite set containing q messages. If q = 2, the source is referred to as a binary source, and the two possible digit values are called bits, a contraction for binary digits. Note also that source outputs, whether discrete or analog, are inherently random. If they were not, there would be no need for a communication system. For example, expanding on the case where the digital information results from an analog source, consider a sensor whose output voltage at any given time instant may assume a continuum of values. This waveform may be processed by sampling at appropriately spaced time instants, quantizing these samples, and converting each quantized sample to a binary number (i.e., an analog-to-digital converter). Each sample value is therefore represented by a sequence of 1s and 0s, and the communication......

Digital

...biggest way of communication to the public. So here are my ways to help improve the nine elements of digital citizenship. Digital access is for people that have devices that they work on for participation in society. So one way to help improve this new generations access, is to give them either a computer or tablet. But, there should be qualifications for low-income families that cant afford it but also limited one per household. This could be done the same way the Obama phones are work. The problem with buying and selling goods through an electronic source is that you never meet or know whom your actually talking business with. Therefore you should have some way to contact that person directly without going through others. Exchanging information with anyone through a device is only going to improve for our futures. One way I can see improvements is by seeing and monitoring those such as criminals, and warn those who they are talking to. Therefore they are alerted of their situations and then they can decide what their options are. One way to improve digital immigrants is by hosting live sessions that are free in local libraries on Digital Literacy. This will help bring some communities together to learn and understand the digital aspect of our world today. This will also give the people a resource that is dependable in answering technology questions. Digital etiquette should be in school classes to help people understand the proper way to use......

Digital Fabrication

...Q1. Summarize, in your own words, what “digital fabrication” is and how it is different from traditional manufacturing tools and technology. What is a digital fabrication? Digital fabrication is the process that merges designing, construction and production that come together at one level. In other word, it is the process of translating digital design into physical objects that is tangible. Digital fabrication is going to allow individuals to design and produce tangible object and that can be by using the new technology that appears in last several years, which is the three dimensional printer along with the three dimensional software programs that help them to do their work more easily by using this technology. Digital fabrication becomes more useful in business areas because using this technology can increase the production line in inventory and that will help firms to be more efficient when they are using this technology which is (3D printer). On the one hand, the digital fabrication adds value for the consumers. Thus, the consumer no longer needs to buy from stores because today, three dimensional printer can do for those consumers what they wants in short time of period, if they owns their three dimensional printer. As an example, if a consumer has an own 3D printer and want to design and print his or her own Mug. He or she goes through several steps. The first step is the designing which the consumer design his or her own mug using the 3D software program......

The Digital Divide

...The digital divide Jamie R. Harris INF103: Computer Literacy Author Note Instructor: Mathias Fok October 12, 2014 The "digital divide" refers to the fact that certain parts of the population have substantially better opportunities to benefit from the new economy than other parts of the population. Internet and computer use has undoubtedly increased in the United States and the digital divide may be smaller within certain population (Neilson 2006). The digital divide separates those who are information rich on one side from those who are poor, who live in an underdeveloped country, or who reside in a rural area with no Internet access. In 1990, 22% of all homes in the United States had a personal computer. This percentage increased to 63% by 2001, and in 2004, nearly 75% of all Americans had Internet access in their homes. While this is a high number, and growing daily (especially among multiple-computer households) there are still a significant number of people without computers or Internet access, and they are getting left behind in school and in the workplace (Bowles, M.D. 2013). Although the majority of Americans now have access to broadband, too many minorities, non-English speaking populations, and members of low income and rural communities remain disconnected. Addressing this digital divide goes beyond providing access to those without it. America must do more to ensure that those who are disconnected understand the need and value that broadband can bring to...

Digital Library

...Digital library development Rapid improvements in information technology have certainly transformed the traditional role of libraries in relation to its daily operation and how it serves its users’ information needs. With increasing number of libraries shifting to automation meant, that up-to-date forms of information technologies and systems are required to store, preserve and disseminate information to users and also it is necessary for libraries to utilize specific collection management system to address users’ demands and need of information and the format of the information required. Having mentioned that, this writing will consider the benefits of having a digital library, why it is necessary to cut back on print library materials and replacing these with electronic resources as eBooks, online dictionaries and encyclopedias and full text journals, also the issues and challenges in relation to digital information and whether this development could work for libraries in the Solomon Islands. Firstly, digital library, electronic library and virtual library are terms that are frequently used to refer to the same thing. Thus in this writing the term digital library will be used when referring to the digitization and utilization of electronic resources in a library. According to Wikipedia.org digital library is defined as, “a library in which collections are in electronic media formats and accessible via computer networks (2014).

The Digital Divide

...INTRODUCTION: Digital divide is a term used to describe the inequality between technology haves and have nots. Sometimes, this can refer to the gaps between first world and third world countries, other times it's used to refer to differences among various population groups within an industrialized country (such as the United States). The technology being measured has been a moving target. Early news articles talked about general computer penetration among households. Then, as the Internet became more predominant, Internet access by individuals became the measure. Now, with free Internet access available through most public libraries, experts discuss the quality of access and usage. Even the term "digital divide" is controversial. "Digital" focuses attention on technology over other factors. "Divide" implies a distinct split. My opening sentence referred to haves and have nots, but can everyone really be separated into one group or the other, or is the difference more graduated?. BODY: Do you think that the digital divide is a major problem inside the United States: Why or why not? YES Digital Divide in the U.S. The Digital Divide is the gap between those who have the skills, access and resources for technology and those who do not. This divide is based on factors such as race and class. In order to have access to the Internet one must have the resource to own a computer and pay for Internet connection. Though comparatively inexpensive in the United States, the cost...

Digital Transformation

...Digital transformation [pic] Summer 2008: Dramatic developments in digital technologies and the diffusion of the Internet protocol as an open and efficient communication standard are wiping out the specialized symbiotic link between content and technology. That’s how Gianvito Lanzolla and Jamie Anderson see the digital world, and here they reveal three trends that companies need to prepare for. Comments In the past, media and technology industries operated through specialized value chains with clearly defined boundaries. Mobile phones were used to make simple voice calls, Walkmans were used to play cassette tapes, and computers existed mainly to crunch data. But new technologies have made it possible to convert different kinds of content – a radio programme, a book, a magazine, a song, a phone call – into digital data; in digital terms, there is little difference between them. At the same time, the Internet and other communication networks based on Internet protocol have made it possible to distribute this digitized content in costeffective and ubiquitous ways. The extent and nature of these changes and their consequent strategic implications remain substantially misunderstood. While some studies have been made, they have mainly had an industry-specific focus, with the consequent limitation of overlooking the systemic effect of ongoing transformations. In order to address this limitation, we researched current transformations in media, telecommunications and......

Cámaras de Sedimentación

...Cámaras de Sedimentación Cámaras de sedimentación por gravedad. Partículas de interés industrial: En general, las partículas arrastradas por corrientes gaseosas varían en su tamaño desde 0,001 a 500 micrones. Las partículas con un tamaño inferior a 0,1 µm están sujetas a movimientos de naturaleza aleatoria ocasionados por colisiones con las moléculas del gas que las arrastra. Las comprendidas entre 1-20 µm tienden a seguir el movimiento del gas y solo las superiores al 20 µm tienen velocidades de asentamiento por acción gravitatoria significativas. Desde un punto de vista pragmático podemos establecer una distinción entre polvo, que asienta con rapidez debido a su elevada velocidad de sedimentación, y las partículas suspendibles, que sedimentan con tanta lentitud que puede considerarse que permanecerán en una corriente gaseosa por tiempo indefinido. En base a este criterio, las partículas que interesan en métodos de colección que utilizan la fuerza gravitatoria como principio de funcionamiento para la separación de polvos son las comprendidas entre 20-50 µm y mayores. El dimensionado de un equipo que permita este fin está estrechamente ligado al conocimiento de la naturaleza del movimiento de una partícula que se mueve en el seno de un fluido. El modelo aceptado es el propuesto por Stokes o ley de Stokes. Principio físico de funcionamiento: Ley de Stokes: Para una partícula que se mueve en un fluido, considerando únicamente la componente vertical del movimiento, el......
