...the Internet of today. Licklider was the first head of the computer research program at DARPA,4 starting in October 1962. While at DARPA he convinced his successors at DARPA, Ivan Sutherland, Bob Taylor, and MIT researcher Lawrence G. Roberts, of the importance of this networking concept. Leonard Kleinrock at MIT published the first paper on packet switching theory in July 1961 and the first book on the subject in 1964. Kleinrock convinced Roberts of the theoretical feasibility of communications using packets rather than circuits, which was a major step along the path towards computer networking. The other key step was to make the computers talk together. To explore this, in 1965 working with Thomas Merrill, Roberts connected the TX-2 computer in Mass. to the Q-32 in California with a low speed dial-up telephone line creating the first (however small) wide-area computer network ever built. The result of this experiment was the realization that the time-shared computers could work well together, running programs and retrieving data as necessary on the remote machine, but that the circuit switched telephone system was totally inadequate for the job. Kleinrock's conviction of the need for packet switching was confirmed. In late 1966 Roberts went to DARPA to develop the computer network concept and quickly put together his plan for the "ARPANET", publishing it in 1967. At the conference where he presented the paper,...

So there it was, the Strowger Automatic Telephone Exchange that cut out the operators’ use and became standard equipment in the telephone systems worldwide until the touch-tone dialing in the late 1970’s. Claude Shannon was an American mathematician and electronic engineer born in Petoskey, Michigan in April of 1916 to a line of New Jersey settlers. Shannon’s grandfather was also an inventor and designed the first washing machine ("Claude shannon,”). Shannon was also fond of inventing at a young age and actually built an off-balance unicycle that made it easier for the rider to juggle while operating the bike. Shannon is known as the Father of the Information Theory from a paper he published in 1948.Besides being responsible for designing the digital computer and digital circuit theory, at only 21 years old, he demonstrated that the...

...1. Discuss the concept of vertical relations between firms and present a case study to illustrate it. This paper will be looking at vertical relations between companies, putting an emphasis on supply relations, vertical integration and hybrids, illustrating the theory with multiple examples in order to better explain the concepts. Vertical relations refer to a logical and natural association between two or more entities as well as their relevance to one another and the linkages in between. This concept can be easily transposed into the business world, as the interdependence amongst companies is a state of fact in the vast majority of cases. As a matter of fact, it is a general truth that companies only achieve self-sufficiency after integrating all links of the supply chain. Even so, there are still operations that need to be outsourced due to a wide variety of reasons (lack of certain competences/”know-how”, geographical restraints, financial feasibility, time concerns, etc.). More precisely, vertical relations refer to the rapport between two companies in the sequence along the value chain, where there can be one (or multiple) upstream company and multiple (or one) downstream companies. Although the typical characterization of the rapport between a company and the market is a direct one (where the firm sells directly to the end consumer), it is generally not the case. In the most familiar scenarios it is considered that the producer would retain...

...INTRODUCTION In the year 1960, RAND Corporation introduced the first computer network to the U.S military. They used command-and-control network where there was only one authority who can convey message which can b3e linked from city to city, state to state, and base to base. However, in spite of its ability to transmit the necessary messages to all concerned, its limitation with regards to its capacity to transmit was not to be denied Four years later Paul Baran form the same company proposed in public the first public networks that have no central authority. It was designed to operate on a get-go transcend were all the nodes in the network would be equal in status to all the other nodes, each node with its own authority to originate, pass, and receive messages. The national physical laboratory in Great Britain set up the first test network of this principal in 1968. Shortly afterward, the Pentagon’s Advanced Research projects Agency funded a larger and more ambitious network nodes were built in high-speed super computers. In fall 1969 the first node was installed in UCLA by ARPANET which can transfer data on a high-speed transmission lines. By 1970 ARPARET grew and its structure expands easily because it can accommodate many different kinds of machine. The original standard for communication was known as the “Network Control Protocol (NCP)”, but as time passed by and the technique advanced, the NCP was superseded by a much higher-level, and more sophisticated standard known...

The main topic of this text is how packet switching works. Packet switching is a digital networking communications method that groups all transmitted data – regardless of content, type, or structure – into suitably sized blocks, called packets. The concept of switching small blocks of data was first explored by Paul Baran in the early 1960s. Independently, Donald Davies at the National Physical Laboratory (NPL) in the UK had developed the same ideas a few years. Two major packet switching modes exist; (1) connectionless packet switching, also known as datagram switching, and (2) connection-oriented packet switching, also known as virtual circuit switching. In the first case each packet includes complete addressing or routing information. 1 PACKET SWITCHING Packet switching is a digital networking communications method that groups all transmitted data – regardless of content, type, or structure – into suitably sized...

...usually a lump-sum amounting to millions, that is paid in the event of a change in control of the company1. The reasons for the implementation of the Golden Parachute is something that has been constantly debated, but the most common objective, and the objective I will be focusing on in this paper is to control the behaviour of the management in the event of a acquisition2. Often times when an acquisition occurs, the management of the acquired firm will not stay with the new firm, meaning that their will not benefit from the acquisition, but would rather suffer if the acquisition occurs. As such they might be inclined to try to prevent the acquisition, and not act in the best interest of the shareholders3. The Golden Parachute serves to ensure that the management acts in the best interest of the shareholders by providing a mechanism to protect their own personal self interest. Another objective that is often talked about would be that of an anti-takeover mechanism4. The Golden Parachute serves as a antitakeover mechanism in a number of ways, but in summary it is assumed to increase the cost of acquisition making the company less attractive for takeover. Through the course of this paper, we hope to learn a number of things about the whole Golden Parachute situation. Firstly, focusing on it being a tool to control the behaviour of the 1 Richard A....

...Jacob Kleintz FYWT Christa DiMarco Research Paper A Culture of Rejection Graphic designer David Carson reflected the grunge culture of the 1990’s through his design of the first issue of the music magazine, Raygun which was published November of 1992. Grunge itself, has its roots in the new music that was emerging as America entered the 90’s. Much of the music shows a disenchantment with society and a sense of entrapment. In 1992, music critic Simon Reynolds said about teenagers in the 90’s, “…there’s a feeling of burnout in the culture at large. Kids are depressed about the future.” By the early 1990's a majority of young adults found the pop music of the time had become too dull and boring. Due to this fact teens turned to a more alternative sound. They found this sound to be produced by college radio and small time record label companies. (Benner). By the start of the 90’s grunge was not only moving to new areas but also began making their own music. Grunge musicians rejected expensive, highly staged performances; most would not use pyrotechnics or other complicated lighting and visual effects during their shows. Grunge ironically arose from a complete rejection of culture (Berman). Carson's style of typography experimentation influenced the development of the deconstructed style of design and a whole new era of designers. The experiments by Carson and other Ray Gun designers were chaotic, abstract and distinctive, but sometimes illegible. The magazine's radical subject...

...Matthew Centrella Technology in Education In our lives today we expect technology to make a difference, and particularly in furthering our education. We see technologies effects as beneficial. We look for it to change, and improve, what has come before it. Technology is the set of means without which certain kinds of constructive activity would be almost impossible. It supports our efforts to appeal to different learning styles, which give us a way to interact with each other and extend the learning experiences. It is a good way to extend the essential skills and knowledge of students. By integrating technology into our educational programs it provides students with additional tools to enhance their learning. Technology allows us to demonstrate teaching strategies and also provide teachers with skills to succeed in the classroom. It changes the structure and the manor in which we learn. Such technologies used in education from the past, present and beyond are the typewriter, computer games, Internet, and communication. Technology and Education (the relationship) The relationship between technology and education can be characterized as a process of change and innovation. In the beginning societies depended on oral communication then the written language was developed. Making an alphabet made learning to read and write much easier then in the past. As technologies of written language became prevalent and more people became literate social structures formed. The next big...

This history revolves around four distinct aspects. There is the technological evolution that began with early research on packet switching and the ARPANET (and related technologies), and where current research continues to expand the horizons of the infrastructure along several dimensions, such as scale, performance, and higher-level functionality. There is the operations and management aspect of a global and complex operational infrastructure. There is the social aspect, which...

...This literature review of academic research suggests that competitive markets in health care can offer patients greater quality, more options, and lower costs. The Federal Employees Health Benefits Program and Medicare Part D serve as two illustrative examples of competition in health care today. Proper reforms to add further competition to the health care industry would be quite significant and would further America’s position as the world’s leader in health care for years to come. KEY POINTS 1. The body of peer-reviewed academic literature suggests that health care can and should operate like a traditional market. 2. Market-oriented reforms have the potential to improve the quality and cost-effectiveness of care, as demonstrated by the Federal Employees Health Benefits Program (FEHBP) and Medicare Part D. 3. Consumer-driven health plans are viable alternatives to traditional plans, and consumers should have the option of choosing such plans. 4. Proper risk adjustment mechanisms can prevent adverse selection. 5. Migrating toward value-based payment systems will result in greater quality of care at lower costs, in part by incentivizing the health care industry to make great strides in offering integrated care, innovative treatments, and personalized medicine.
