From Physical Machines to Virtual Machines
Anthony V. Lear
ITT Technical Institute

From Physical Machines to Virtual Machines For years businesses have depended on multiple pieces of hardware, linked together and deployed with software, to connect users to the resources they need. As technology has advanced with today’s virtual software programs, we can now run another “virtual computer” on a physical client machine. With all the technology advances some people believe that virtual machines are equal to physical machines. First, let’s get some background of the physical machine (server/client) and what it has to offer a network. There are many options when it comes to the CPU, Motherboard, Memory (RAM), etc. These options include hard drives (storage), video cards, audio cards, and central processing units (CPU’s). Even though “it’s all just computation” (Nikhil, 2011, p.38) the combination of hardware can make or break the performance of a physical machine. IT professionals have to consider the needs of a network when choosing a physical machine. Depending on how it will be utilized on the network this will then elaborate on the requirements of the machine to provide the capabilities needed to perform its role on the network. For instance, if you require a file server to allocate resources such as software, programs, employee documents, etc. you will have to consider the servers hardware needs to meet this demand. The most important considerations for a file server are storage, memory, and CPU. Storage capacity is always an issue with any physical machine, the more storage a machine can hold the better it can perform. The next consideration would be the CPU. Depending on the processor’s capabilities (number of cores, speed, and socket type) will impact how fast users can access the resources available to them. Memory is another important…...

Snack and Soda Machines Should Be Removed from Schools

...Nick Conklin English Period 7 Snack and soda machines should be removed from schools because students are attaining unhealthy eating habits. In recent years, schools have been pushing to reduce obesity levels. Students have a higher risk of diabetes, hyperactive behavior, and hypertension. This is happening in teens under 18. Schools want to encourage their students to eat healthier meals, but students don’t have many options for a healthy choice. Most machines are filled with sugary snacks like cookies and potato chips. “Access to and consumption of sugary and unhealthy foods and drinks have led to a childhood obesity rate that has tripled in the past 30 years, with one of every five children obese,” reports the federal Centers for Disease Control and Prevention. Most teens receive 13 percent of their calories each day from sugar-sweetened drinks, including sodas, sports drinks and specialty coffees. A single can of soda has about 150 calories. A child can increase caloric intake by 300 calories. In fact, a study conducted by the Division of Epidemiology at the University of Minnesota showed that school aged children who drank soda consumed close to 200 calories more than those who didn't. A pound of fat is equal to 3,500 calories. This is a potential weight gain of almost 20 lbs. a year from drinking soda. Snack foods or "junk" foods, such as chips, cookies and crackers are usually high in fat. A gram of fat is worth about 9 calories, but a gram of protein or...

Future Machine it or not, machines will play an important part in the future. They already play such a large role in our life, it’s almost inevitable. Over the past 20 years, the use of computers has skyrocketed. Now there is almost one in every home. Children of this generation are being taught to use computers at a very young age. Computers are used in most every office, also. Jobs that used to be done by men can now be done by machines. Technology is growing each day. Jobs are being replaced by machines, and there is more need for people familiar with computers or technology. In a lot of cases as far as jobs etc go, it’s something you need to know or something that helps considerably. Technology is becoming more advanced. As the technology changes, so do our lives in a small way and it shall continue into the future. Technology has changed our lives for both better and worse. It has made life so much easier. Now instead of baling the hay themselves, farmers can put the hay into a machine that makes bales. It is not only more efficient, but the outcome is much more desirable. Laborious jobs have been reduced or eliminated. Though it has made life easier, it also has promoted laziness. Instead of using our physical ability to accomplish a job, so many can now be done by machine. Rather than walking to the store to pick up margarine most would drive to the store. Little things that are so easily accomplished by hand can now be done mechanically. We’d rather have a machine do the job,......

Electric Machines

...Science 6.685 Electric Machines Class Notes 1: Electromagnetic Forces c 2003 James L. Kirtley Jr. September 5, 2005 1 Introduction Bearings Stator Stator Conductors Rotor Air Gap Rotor Conductors Shaft End Windings Figure 1: Form of Electric Machine This section of notes discusses some of the fundamental processes involved in electric machinery. In the section on energy conversion processes we examine the two major ways of estimating electromagnetic forces: those involving thermodynamic arguments (conservation of energy) and field methods (Maxwell’s Stress Tensor). But first it is appropriate to introduce the topic by describing a notional rotating electric machine. Electric machinery comes in many different types and a strikingly broad range of sizes, from those little machines that cause cell ’phones and pagers to vibrate (yes, those are rotating electric machines) to turbine generators with ratings upwards of a Gigawatt. Most of the machines with which we are familiar are rotating, but linear electric motors are widely used, from shuttle drives in weaving machines to equipment handling and amusement park rides. Currently under development are large linear induction machines to be used to launch aircraft. It is our purpose in this subject to develop an analytical basis for understanding how all of these different machines work. We start, however, with a picture of perhaps the most common of electric machines. 2 Electric Machine......

Organizations as Machines

...Gareth Morgan Images of Organizations Organizations as Machines The central thesis of Gareth Morgan’s book ‘Images of Organizations’ is that all developed theories of organization are based on implicit metaphors. By this, the author tries to give a deeper insight into the nature and design of organizations, as they have tremendously changed and further developed over time. In the following, I will demonstrate how the metaphor ‘Organizations as Machines’ can be used to highlight certain aspects of organizations and to generate deep understandings of the nature of organization as well as organizational life referring to this distinct, very sophisticated metaphor. Viewing an organization as a machine shapes our perceptions, expectations and actions in profound ways. We take for granted our ability to design and operate machines to do exactly what we want them to do. We expect consistent performance, each part executing its function without variation. Planning in a mechanistic organization can be seen as the creation or construction of a detailed blueprint, everything exercised to efficiency and maximization with predictable outcome, standardized and designed as precisely as possible to diminish any possible endangerments. When seeing an organization as a machine, the plan would obviously be the focus. Despite, it is not important who created the plan or who participated in drafting it, but the quality of the plan is of capital importance. It is the basis, the......

Experience Machine Objection

...Experience Machine Objection Utilitarianism is a normative moral theory, which suggests that actions are seen as right if they tend to produce happiness to the majority and wrong if they tend to be wrong if they produce unhappiness. This theory can take on the form of act utilitarianism although in this essay, I will be focusing solely on hedonistic utilitarianism as well as an objection to this theory, the experience machine objection. Robert Nozick introduced this objection. Following an explanation of both hedonistic utilitarianism and the experience machine objection I will be critically evaluating the objection. I am going to argue that the experience machine objection is valid against hedonistic utilitarianism because there are people who would not plug into the machine. There are some people who prefer to physically do things not just experience them, don’t want to be limited to a man-made reality and want to make a difference in the world. Two key contributors to the normative moral theory of utilitarianism are Jeremy Bentham and John Stuart Mill. Utilitarianism specifies what makes an action morally correct or incorrect. The theory suggests, “actions are right in proportion as they tend to promote happiness and wrong, as they tend to produce the opposite of happiness.” (Mill 454) It is a type of consequentialism as even though the act itself may be morally wrong, if it produces the best consequences it is seen as a morally right action. For example, killing one......

Vampires: Killing Machines or Sex Machines?

...Callan Parker Ms. Faith Dickens English Honors II May 30th, 2014 Vampires: Killing Machines or Sex Machines? The sexualization and carnality of modern vampires can be tied to the commercialization of peoples interest in the supernatural and a contrasting society. In less than a century, vampires have gone from scary and repulsive monsters to beautiful, mysterious creatures. This transformation is brought on by the common advertisement of sex and the attentiveness of people to abstract societies nowadays. The look and feel of vampires has also changed due to the resources of entertainment producers and a capitalist society focused on building revenue. Nosferato vampires compared to modern vampires: In Nosferatu, the most important and popular element in the movie was the accuracy of Dracula/Count Orlok. The description in the book matches the actors portrayal, “…a tall old man, clean shaven save for a long white mustache, and clad in black from head to foot, without a single speck of colour about him anywhere,” (Stoker, 21). Later in his letter, Jonathan mentions the physical structure of the Count who stands before him: “His face was a strong—a very strong—aquiline, with a high bridge of the thin nose and peculiarly arched nostrils …The mouth, as far as I could see it under the heavy moustache, was fixed and rather cruel-looking, with peculiarly sharp white teeth; these protruded over the lips, whose remarkable ruddiness showed astonishing......

...Should machines be used to do good and services instead humans? I believe they should not for many reasons. Machines can not be smart unless a human is controling it. So it would not matter if its an intelligent machine or not a human is still controlling it to do everything. When using a machine it could easily malfunction and it could be hard to fix the problem or it will just take a while to fix it. If a human is taking over instead of the machine there may be fewer problems. Machines have so many problems that it would not be worth having. Also, the more machines you have the less jobs there are for people because everyone thinks it would be better to have machines instead of people. When less people are out of work that means less money for those people and sometimes they will lose their homes or cars because they can not afford anything. Sometimes working with machines can be very stressful because they may not work at times or they could be running extremely slow and won’t get anything done. Machines are not smart at all, only when people are controlling them they are but not all the time. It may seem smart but its really not. In conclusion, I think machines should not be used to take over a human job because machines can not think only humans can think and make right or wrong decisions. Machines do not have brains, their not wired to think so why have them do stuff that we can do ourselves....

A Man-Machine Interface

... Abstract The Man Machine Love-Hate relationship is examined and the eventual blending of the two to create an augmented form of reality. The problems with such a task are not only with the hardware but with the Human sense of spiritual bonding to the past. A past imbued with fear, pain and hardship, a meta-ethnic past that some long for and believe to have been a simpler time. The Personal Computer will someday become an invisible extension of our minds with no peripherals nor external hardware to obstruct the users from achieving their creative goals. From its beginning mechanical computers have frightened Humans who believed that they would be replaced by these thinking machines. The human beings mechanical mobility has evolved out of our spirits need to interact with the universe and the next step, the one that frees mankind from physical limitations will be the use of machines that will be ubiquitous, in effect, working as natural extensions of the body. The continuous innovations in electronics are making more and more components ubiquitous. The convergence of man and machine requires that computers become an integral part of the human body. The hurdles are many and those in opposition of such a world are afraid that these changes can only come about with the sacrifice of the soul. The last huddle that will stand in mans way of a true Man-Machine interface may well be one of posed by the threat that others may seek to control the machine portion and enslave...

Time and the Machine

...In Aldous Huxley’s “Time and the Machine” the author is unenthusiastic with the use of the present generation’s use of time management as opposed to previous generations. In the past, people were more involved with nature, they enjoyed taking walks and kids ran and played outside more. Nowadays more children would prefer to remain in doors and play video games or surf the internet instead of a game of “jump rope.” Nature is relevant in this work due to the author’s frustration with time being spent elsewhere instead of with nature. Place is referred to how time is different between generations of the past and generations of the future. “Eco-Defense” by Edward Abbey was a very interesting periodical. Abbey stated that it is essential for people to care for and defend their wilderness as if it were their child because it is their home. He made reference to the government valuing more for their pockets/own personal gain and big business rather than the value of land and the people. His work was very interesting to me because God created Man from the dusts of the ground, so the wilderness is our “home.” Nature is represented by the wilderness and place is given presence by the difference of what we consider to be home. James, M. & Merickel, A. (2010). Reading Literature and Writing Argument (4th ed.). Prentice Hall. Mallory I really enjoyed reading Eco-Defense. Abbey’s call for people to defend their American wilderness was insightful and interesting, as he claims......
