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 anywhere in the world took nearly 140 years yet advanced society light years into the future.
In today's modern communication modes there are a wide variety of methods for communicating not only the spoken word, but the written word, text, images, pictures, books and entire libraries of information at a press of a button. There are also a number of digital methods for transmission, including but not limited to; TETRA (terrestrial trunked radio), the Internet via Widebrand and Broadband, and a variety of networks used for public and private transmissions. Many of these methods carry more information than Alexander Graham Bell likely ever even imagined. One recent article found that "3G cellular networks can usually handle data rates of several megabits per second" (Evans-Pughe, 2011, p. 75); or in other words, more information in one second can now be transmitted than what the Library of Congress had in its archives during the Bell era.
The rate of transmission and what is being transmitted is an astounding display of man's creativity and the fact that such creativity is not being limited to one nation or region is a reason...
74).
One could ask what is the draw of digital communications? Besides the obvious instant communication capabilities with loved ones in remote places, some of the other uses include games, streaming video and entertainment. The Daga et al. study determined that "China's digital usage, which is similar to that of the United States, skews toward instant messaging, social networks, gaming, and streaming video" and that "increasingly, Internet users in China are substituting digital media for traditional ones, with the potential for further cannibalization as digital consumption grows" (p. 17). The same study determined that only seven percent (81 million) of India's population currently has access to digital communications. One can only imagine the future growth of communicating digitally with awe and amazement.
It's not only the capacity of digital communications that is mind-boggling, it is also the speed, distance, accuracy and clarity of today's communications network that are astounding as well. Currently there are a number of avenues being examined that may increase the digital capacity even more. One such method is described as a chaotic system; instead of using a linear approach to transmitting data it uses…

Communication Verbal communication includes the words that are physically spoken, as well as factors, according to the video, such as tone of voice, rhythm of speaking, word choice, and emphasis. Experts and researchers in the field of communication assert that nonverbal communication composes more than half of the communication among people. Nonverbal communication has a variety of factors such as eye contact, gestures, body language, the setting, and even the dress
Digital Privacy in an Information Technology Age Information privacy refers to the desire of individuals to control or have some influence over data about themselves. Advances in information technology have raised concerns about information privacy and its impacts (Belanger & Crossler, 2011). There are many definitions for information privacy, but there is little variance in the elements of the definitions, which typically include some form of control over the potential secondary
To Choose an Accounting Topic That Would Be Excellent for A Dissertation. Research Topic Taxation in the digital era is an excellent topic for a dissertation because there is an ongoing debate on whether digital companies are paying their fair share of taxes. Some tax experts believe that digital companies enjoy tax levels close to zero compared to traditional companies, yet they earn huge profits. The underlying principle of corporate taxation is
Communication Skills Self-Assessment Interpersonal Communication Speech and language pathologists are considered to be experts in the field of interpersonal communication. Yet these professionals readily agree that although they may be experts in disorders of communication, they "are not experts in 'communication,' particularly that of interpersonal communication" (Montgomery, 2006). A fundamental reason that someone might not be skilled in interpersonal communication is that they have difficulty attending to and processing all of the
Other cable news channels and the broadcast news shows also offer infotainment. Like CNN, the content and points-of-view generally do not challenge and I have found that the mass media underestimates the intelligence level of the viewers so much so that content is "dumbed down." However, some television news sources are able to break the mold. Comedy news spoof program the Daily Show makes fun of the media's faults while
