Abstract
The writer looks at how the concept of a camera and film has evolved and been transformed over the years. In this paper, the writer examines the workings of a digital camera. The article includes relevant illustrations. The writer also considers the benefits of digital cameras over film cameras.
From the Paper
"Cameras of all kinds-still video film digital-have become so ubiquitous that Americans seemingly take them for granted. Once cumbersome to the point that taking a photograph required subjects to sit still for several minutes, today's cameras have progressed to the point that they exist in cellular phones. Despite the fact that digital and film cameras are both called cameras they use significantly different technology to capture images. This research considers how film cameras evolved into digital cameras and the advantages associated with the ... "

Abstract
This paper argues that digital cameras are better than analogue cameras. Specifically, the paper looks briefly at the history of digital photography, at its utility in matters such as record-keeping and crime-fighting and at some noteworthy instances of digital photography producing impressive and compelling works. Finally, the paper looks at all of the various reasons why it may be said that digital black and white photography is better than analog black and white photography.
From the Paper
"More than that, the technology that makes digital black and white photographs possible always runs the risk of becoming obsolete. For instance, the old Epson 2200, 7600, 9600 printers have been pushed aside by Epson Stylus Pro 4800, by the Epson Stylus Pro 7800, and by the Epson Stylus Pro 9800 (FLAAR Network, para.8); simply put, unlike the fairly low-maintenance prints rendered by analog cameras, the "splashy" digital B&W prints of today place photography enthusiasts in the uncomfortable position of seeking out new technological tools that have a (quite literally) a built-in obsolescence factor. Be that as it may, though, most photographers will gladly accept this trade-off if it means the chance to be more creative."

"Storage virtualization is able to accomplish this by making physically separate and heterogeneous storage arrays seem to be a single logical pool of storage resources, controllable from a central console. The purpose of the program is for data to freely flow between the different tiers and types of storage, depending on business needs, without disturbing the operating environment. The author also asserts that "The single most important attribute of any storage virtualization solution is the ability to mask complexity and thereby make manageable that which is increasingly unmanageable.""

Abstract
This paper explains that, in spite of the usefulness and potential of the digital imaging process in hospital radiology departments, the cost of the equipment it requires has stopped digital imaging in hospital radiology departments from progressing and growing as fast as was hoped. The paper also explains that the slow progression towards digital imagery does not mean that the importance for the future that the technology holds should be discounted. The paper then discusses the two main types of digital imaging systems as they relate to hospital radiology departments and concludes with a discussion of image quality and its significance. A copy of the source documents used are also appended to the paper.

The Evolution of Digital Imaging
Computed Radiography (CR)
Digital Radiography (DR)
Image Quality
From the Paper
"Digital imaging in hospital radiology departments came about for several reasons. The most important of these, however, was the idea that the digital images could be viewed by any authorized person at any time, thus making it much easier and faster for those that needed to see them to have access to these images (Gillespie, 1999). These digital images eliminate the need for films and film libraries, thus freeing up space, as well. However, there are still problems with this issue that have stopped digital imaging in hospital radiology departments from progressing and growing as fast as was hoped. The major concern for these departments is the cost that is incurred when it comes to the digital imaging equipment, which is much more expensive than the older methods that were previously used to take x-rays and perform other functions (Gillespie, 1999)."

Abstract
This paper discusses digital television, comparing it to analog television. The paper presents an explanation and assessment of the current laws and mandates regarding digital television in America and in the United Kingdom. The paper explores the technology involved and provides examples of several cable companies that offer digital television.
From the Paper
"Though some providers of digital television like Sky claim that weather conditions do not affect the clarity of images on digital television, this fact has been demonstrated as not being true. Weather does affect digital images and there is a certain amount of corruption present. In fact, though the images are better than those of analogous television, the limitations of the compression technology that is used for digital television is apparent in the manner in which ?digital artifacts? or ?after images? as they are better known occur on the television when the picture changes much too fast, or even when other channels are fighting for the same bandwidth at the same time. Digital television must not be confused with ?high definition? television; in fact digital television occupies the same number of lines of 625, as the analogous television."

Abstract
This paper reviews and discusses the history of photography. According to the paper, George Eastman introduced the first film roll in 1884 and the first camera called a Kodak, in 1888. The paper then goes on to discuss the digital camera and the development of photography.
From the Paper
"There were many attempts until the XIX century to capture drawings or images using the reaction to light, but the resulting work always deteriorated. In 1816 Joseph-Nicephore Niepce succeeded to capture the first negative images, using paper treated with silver chloride but failed to fixate the image. He managed to achieve positive images using a pewter plate covered with a petroleum derivative called bitumen of Judea . Although ti was successful there were still many problems to cover. He received the reversed image, and the exposure took hours to fixate the picture, which caused the sun to move and alter the position of the light. Louis Jacques Mande Daguerre, interested in Niepce's work conducted his own researches. In 1835 he published his first results, called daguerreotype. This was a sheet of silver-coated copper, treated with iodine vapor. He achieved to reduce the exposure time to 30 minutes, achieving a barely visible image that he later revealed with mercury vapor and fixated with salty hot water. "

From the Paper
"This paper will discuss the concept of digital recording, with a focus on digital audio tape (DAT) recorders. The methods of digital recording sharply contrast those of analog recording which preceded them. Analog recording is based on the concept of capturing the shapes of sound waves as they vibrate in the air. In an analog recording, sound is "stored as a physical representation of the original soundform". An example of this can be seen in the squiggly lines which form the grooves on a phonograph record. With digital recording, on the other hand, computer technology is used to convert analog waveforms into numerical, or digital, data. In a compact disc (CD) player, this data is read by means of a laser; in a DAT player, it is read by means of a rotary tape head. Because digital recording uses numerical data instead of physical ...

Abstract
This paper defines digital radiography as a branch of radiography which converts X-ray images to electronic data which can then be viewed and read by radiologists on a monitor. The writer stresses the convenience of being able to store digital radiographic images on computer discs. This paper details the various uses and advantages of digital radiography including the fact that this particular method is quicker and far more accurate than the previous practice of producing x-ray images. This paper discusses the differences between computed radiography and digital direct radiography while also delving into the pros and cons of both radiographic methods.
From the Paper
"The 'Direct Digital Radiography' System provides options for the transition to digital technology. This system offers the highest quality images that are available in DR today. Developed only in recent years, the system can be used across a large number of potential applications. The advantages of the system are that it consists of two types of detectors, one direct and the other, indirect. In the setup for its imaging, indirect sensors convert x-rays into light, and then convert that into electronic signals. The images depend on both signal profiles as well as on image resolution. The system relies on a scintillation method, wherein x-ray energy may be converted into light, and this light can then be converted into electronic signals by thin-film diodes."

Abstract
This paper discusses the music recording industry and how it has been impacted by digital music distribution. The paper relates that the early success the music labels had against the initial music file downloading sites were short lived, and legitimate digital downloading sites have since prospered. The paper then argues that major recording labels are suffering from the decline in CD sales, not because of music pirating, but because they refuse to recognize that consumers demand digital music downloading for its convenience and portability. The paper further emphasizes that digital music distribution and retailing is the future of the music industry and every relevant party seems to recognize this, except the music industry itself.
Outline:
Overview
Restructuring of the music Industry
New distribution model & Itunes
Online distribution variations
Conclusion
From the Paper
"The music industry, in spite of its ineptitude and obstinacy over the past decade regarding digital music downloading, is finally realizing that whether it embraces downloading services such as iTunes and others, it must evolve with the digital age or face irrelevance. In order to compensate for the loss of revenues, the recording music industry has been examining their base revenues in order to determine if digital downloads can compensate completely for the decline in sales of CDs. Two of the major record labels, Sony and BMG, have even merged in order to expand their catalogues (Recording, 2007). There have been efforts made to encourage EMI to merge with one of the remaining three major record labels but thus far these remaining major record labels have resisted further consolidation. However, EMI undertook its own internal restructuring by merging its two main record labels in the US market during the first half of 2007 and Warner Music was sold during 2004 creating even more churn in the industry (Recording, 2007). Yet, perhaps the most visible change is the industry is the downsizing or disappearance of retail music stores, which has begun to accelerate."

Abstract
As the globe becomes more dependent on digital technology to exchange information over the Internet societies are becoming more concerned with issues of privacy. Individuals surfing the net, purchasing products over the Internet, and corresponding with others via the World Wide Web are required to provide personal information that has the potential of being used illegally in many ways. The United States has relied on the wording of the fourth amendment of the constitution in past years to address privacy issues in the country. Yet, as digital technology has evolved the focus on this amendment to resolve privacy concerns in relation to digital media is restricted by privacy in relation to search and seizure. This paper discusses the issues of privacy in relation to digital media, focusing on how these issues are handled in the United States and Canada.

Abstract
There are many in today's society who do not have access to the internet and this fact automatically makes them 'digitally challenged'. This paper analyzes three articles which tackled the different dimensions or facets of the digital divide in the United States. Through the article analyses, the researcher posits that the problem of digital divide has multiple, rather than one, facet. This means that at present, the internet-oriented society confronts 'digital divides' of different kinds: Stratification in terms of access, use and even knowledge or education about the internet.
From the Paper
"At present, societies from all over the world are rapidly becoming Internet-oriented, where almost all daily activities are mediated by or use Internet and computer technologies. The vital role of the Internet is especially addressed in increasing one's level of knowledge and becoming an aid in achieving formal education. Moreover, because of the generally-beneficial effects of Internet technology to society, accessing and using it has become imperative for all members of these Internet-oriented societies.
However, a digital divide exists despite the proliferation of Internet technology and use. There are still stratified groups that do not have access to the computer and Internet. Moreover, apart from lack or absence of access, the lack of skills and knowledge to use the Internet is another problem that relevant institutions such as the government and schools have been trying to curb by offering free access and training programs to the public about Internet use."

Abstract
In this article, the writer discusses how the act of business transactions have changed due to the progress in technology. The writer examines the effect of digital signatures on e-commerce, including the need for digital signatures. In this paper, the writer explores how digital signatures work. The paper also discusses the outlook for the future. Further, the writer looks at the importance of identity in cyberspace.
From the Paper
"For thousands of years transactions between individuals were conducted face-to-face. There was little doubt about who the buyer or seller was and when cash was involved it was not necessary to know for certain who was whom. Indeed even in today's high-technology world, cash transactions still carry the greatest amount of anonymity since the funds are guaranteed. As credit became more and more common, it became necessary to ensure that the persons involved with commercial transactions had the authority to perform those transactions."

Abstract
This paper discusses the issues and challenges involved in an enterprise-centric approach to the managing of digital content. The writer specifically focuses on the management of medical imagery, a field commonly referred to as digital asset management. Additionally, the writer discusses the need for standards that provide for the creation of digital medical imaging systems.
From the Paper
"At the center of integration efforts within the medical digital imaging system design efforts in the industry today is the creation of the virtually integrated electronic patient record (VIEPR), which is the basis of the future generation of wireless and web-based applications that are capable of "tracking" to patients as they progress through treatment programs. The VIEPR concept is aimed at taking digital medical imaging strategies and making them on an "always on" status that patients can present for analysis by medical professionals including radiologists and medical specialists. The future of thin-client based medical digital imaging delivery applications is based on this technology."

Abstract
This paper explains how scanners can transfer text and pictures into digital form for manipulation and storage. The author points out that digital imagining allows storage in a smaller area. The paper relates that digital imagining manipulates information into a different format for use in desktop publishing of company documents and similar uses.
From the Paper
"Digital imaging has a wide variety of uses today, serving as a new means of photography, empowering office copiers, allowing for the transfer of images over long distances, and so on. Digital technology is computer technology translating information into a series of numbers, computer code that can be read and transformed back into the original form. Digital information can be text, sound, or pictures when translated, and in its digital form the information can be stored, retrieved, sent from one place to another, and altered, all with greater ease than changing the original material. Digital imaging in the workplace is found in office computers, copiers, fax machines, databases, and so on."

Abstract
In this article, the writer notes that today, healthcare practitioners enjoy a wide range of digital equipment that can help them provide more efficient healthcare services, including laptop computers, cellular telephones and personal digital assistants, or PDAs. The writer points out that these devices have been used in various ways by clinicians to improve their ability to deliver more timely and accurate diagnoses and treatments and it is clear that the use of these devices will continue to increase in the future. The writer provides a current snapshot of how personal digital assistants are being used in various healthcare settings, including military and government tertiary facilities and the use of PDAs on the battlefield in times of war, but with a specific focus on how PDAs are being used in nongovernmental healthcare facilities today. To this end, a critical review of the relevant peer-reviewed and scholarly literature is provided to describe the general history and evolvement of PDAs, a recapitulation of current literature and research studies, a discussion of how these devices are currently being used in the healthcare arena, and an estimation of future trends based on the foregoing descriptions. A summary of the research and relevant findings are presented in the conclusion.
Outline:
Review and Discussion
History and Evolvement of PDAs in the Healthcare Field
Current Literature and Research Studies
Application of the Area in the Healthcare Arena
Visions for the Future
Conclusion
From the Paper
"The research showed that personal digital assistants, or PDAs, are increasingly popular handheld devices that provide users with a vast array of functions and features that are particularly useful in healthcare settings. The research also showed that while PDAs are becoming smaller and more powerful, they are also becoming easier to use, but some healthcare practitioners may be reluctant to invest the time needed to learn how to use these devices efficiently today. There appears to be some good reason for this reluctance on the part of many healthcare professionals as well. Past trends suggest that PDAs, like other digital devices, may well just be interim technology that will be eventually supplanted by the ubiquitous computing environment that many observers predict will be firmly in place in the near future. In the meantime, the research was clear in showing that more and more people are using PDAs in their personal and professional lives, and healthcare providers are no exception. A few studies concerning how these devices can be used in various healthcare settings have already found their way into the peer-reviewed, organizational and military-based literature, and it is reasonable to conclude that new applications for PDAs will continue to be identified in healthcare until such a time as a superior technology emerges to replace them. Finally, the U.S. Department of Defense was shown to be a firm advocate of the use of PDAs by healthcare providers as part of its ongoing initiative to transform the battlefield into a comprehensive digital environment wherein resources can be more effectively deployed and better use of existing resources can be accomplished."
