These include microelectromechanical systems (MEMs), "such as sensors and actuators, and digital signal processors that enable cost reductions and extend it into new types of devices. Examples of MEM devices include ink-jet printer cartridges, hard disk drive heads, accelerometers that deploy car airbags, and chemical and environmental sensors" (Gulliksen 2000).
Trends toward improvements in microelectronics and MEMs are expected to continue as well in information storage, networking and applications of information technology (it).
Information storage is necessary for a digital computer. Its process, not being analogous, need to be stored and then reused as the problem advances. Disk drives and other storage for information are improving in cost and performance. The amount of original information that can be stored has expanded so much that it is now estimated that most of the information in the world is now stored on various kinds of disk drives. And as the world wide web expands, this information has become increasingly available to everyone. Computers have improved incrementally with the amount of storage space made available, due to improvements in other areas, such as semiconductors, increasingly inexpensive and efficient microchips and the world-wide acceleration in the production of less expensive computers.
Networking is another reason for the trend in the growth of digital design, versus analogous design for computers. As computers connect to each other in networks, both wide area and local area networks, specialized software and hardware are becoming standardized and Internet based. As more people connect to the networks, the acceptance of the original digital design is becoming committed. Worldwide, there were 100 million Internet hosts or server computers connected to the Internet, in July of 2000, an increase from 30 million just two years earlier.
As the array of applications that make it more useful to everything from cars to individual computers to huge corporations, become more powerful and convenient, the use of digital design has left analogous design far behind. Originally, the digital computer was used primarily to process data, but their use expanded to word processing, spreadsheets and database programs. However, over the last twenty years, software has so improved and enabled applications, that uses have been expanded to "educational software,...
Digital Signature Scheme Based on Factorization The objective of this study is to discuss an issue in cryptography or computer security. Digital signatures are described as "an analog of handwritten signatures" which are based on "the physically idiosyncratic way of signing one's name. But they can be easily forged." (Grabbe, 1998) The digital signature is "a mathematical method of attaching one's identity to a message" and is held to be more
Digital Sound Synthesis and Usability Testing Overview of analogue/digital synthesizers and their input in the music industry An essential issue in the researches of new media happens to be to investigate and clarify the connection between technological development and cultural revolutions. In this case, digital technology has usually been seen as the single most significant tool in the design of numerous of today's new cultural terminologies. In media that is heavily reliant
This phenomenon is referred to as the filter roll-off generally expressed in Decibels of attenuation per octave of frequency. When a filter is designed there is the intention of making the roll-off as narrow as achievable which gives the filter a chance to get as close as possible to the intended design in terms of performance. There is a difference that exists between the upper and the lower cutoff frequencies
45). There are also important racial issues that are examined throughout "A Touch of Evil"; these are accomplished through what Nerrico (1992) terms "visual representations of 'indeterminate' spaces, both physical and corporeal"; the "bordertown and the half-breed, la frontera y el mestizo: a space and a subject whose identities are not fractured but fracture itself, where hyphens, bridges, border stations, and schizophrenia are the rule rather than the exception" (Nericcio,
We owe our engineers a pat on the back for the part they have played in creating, designing, implementing, and perfecting these new technologies. Technologies that many people take for granted works because of good digital design. Digital cameras, wireless networking hubs, and digital voice recorders all work because of digital logic. Video game consoles and game boy technologies would be absolutely unthinkable without digital design wherewithal. Even cars
Digital communications could be described as being borne from the first electronic transmission of words via a wire uttered by Alexander Graham Bell. Those words; "Watson, come here. I want to see you" (American Treasures, 2010) will live on in historical fashion as a changing of not only the manner in which individuals communicate, but the changing of an entire world. From that era to today's digital communication accessibility almost
