Network Security Essay Example for Free

Network Security Essay You are interested in starting your own Music Store, QualitySounds, in a suburban area of your town. You need to design and build a network and computing solution for your stores. You have done some initial planning and you will start with two stores (but you plan to add two more stores across town within one year). Your store will sell new and used music and allow customers to get â€Å"online† in your stores and download music. You also will offer classes on how to setup music downloads and configure MP3 devices. You took computer networking courses in college and you feel you can tackle this solution yourself. Upon initial planning, you have identified the following requirements for your network: * Connects three office computers and one computer used for Point-of-Sale (POS) services at each of your stores. You also want six (6) computers in the lobby/store where patrons can download music and you can run â€Å"training classes† for people to learn about using MP3 players and get other basic information. The two offices have to be connected into one cohesive network, sharing POS services and other critical company information. You also need to provide a â€Å"hand out† casual area for people to stop in and discuss music and connect wirelessly to the Internet (you might even offer free coffee to entice people to come in to your store). * Provides adequate security for all of the company communications and documents (especially sensitive sales documents). All POS services must be protected. All general network access should be segmented from the company POS services. * Fast and have additional capacity as the company grows * Provides for centralized printing * Supports the eventual addition of other stores to the network * Provides customers with a general information Website and a secure Website where clients can buy services, and products * Provides for limited downtime (24 hour downtime maximum) * Provides for centralized management and control of the computers in the two stores, so that you can maintain the network from off-site * Provides for long-term cost effectiveness * Provides a suite of software tools for the employees to effectively communicate and a POS solution for the stores The company does not have any equipment. Your plan should include a complete network and computer system that meets these requirements and future expansion plans. The two store locations will (eventually) be within a five-mile radius of each other. The locations are within a suburban area that has current technological infrastructures and related technology offerings. The stores will need a sales system and print services for invoices. Complete your proposal including costs for computing equipment, network infrastructure, network servers, printers, and related hardware, software, and accessories. Include as much detail as possible as well as justification as to your selections. Diagram and explain your physical network and computer design as well as the logical network design (server installation, domain layout, etc.). As you are a small business, cost is a major factor and should be minimized.

Abstinence Only Sex Education Essay -- Sex Education

Where in the first world would one expect the teen pregnancy rate to be the highest? Surprisingly, it is the United States that has the highest teen pregnancy rate of any first world country, more than double the rate of twenty other first world countries and almost ten times greater than that of Switzerland. While some of the disparity can be attributed to factors such as income inequality, the presence of abstinence only education has a major impact on birth and STD rates in the United States in comparison to other countries with more comprehensive programs. It is clear that this difference in approaches has a significant effect, and the United States needs to act to ensure the health of its citizens. Urgent actions are necessary because abstinence only education is becoming more popular in the United States and more and more school districts are adopting it. Despite its popularity it has not been proven in any way to be effective in meeting its goals of reducing teen pregnancies and STDs. In fact, there is strong evidence and reasons for its ineffectiveness that should, when compared to the dearth of evidence showing any benefit, make it clear that this is not an effective approach. Not only is it ineffective however, it also results in harm to American teenagers and society by attempting to discourage sex by saying condoms are not safe, and this results in decreased contraception use and thus more STDs and pregnancies. And finally, when America and other first world countries with abstinence only curricula are compared to countries which have a more comprehensive methodology to teaching health, it is clear what is the more effective approach. Abstinence only curricula targeted at adolescents are both ineffective at meeting th... ...ent Education: Ine." bepress Legal Series . N.p., 2004. Web. 25 Apr 2012. Santelli, John, Mary Ott, et al.

Renaissance Philosophy Essay

I believe that the Renaissance philosopher who has provided the greatest contribution to humanity is Rene Descartes, whose aggregate contributions to intellectualism in Western culture are difficult to overstate. His significance lies in his judicious use of skepticism in the assessment of truths and beliefs frequently held up as objective knowledge. Descartes was a Catholic, but this did not necessarily mean that he took its authoritative and hegemonic role in the maintenance of knowledge at face value. He realized that certain truths cannot be satisfactorily determined through Church teachings alone, and therefore what must be held up to close scrutiny is not ‘truth’ itself but the criteria used to assess it. Granted, Descartes was not the first person to examine such issues. The skeptical tradition dates as far back as the first millennium AD. But rather than asserting that truth has no value, Descartes was concerned with the development of a unified and almost arithmetic means of measuring knowledge. This sense of skepticism blended with a belief in ordered reasoning is reflected in his other pursuits, particularly mathematics. This combination of mathematics and sophistry is made most manifest in Cartesian dualism, which argues a divide between the nonmaterial mind/soul and the material of the body that influences each other. However, it is Descartes’ ordering of metaphysics that has provoked the most significant amount of reaction and influence in equal measures supporting or contradicting him. Descartes believed that in order to prove the existence of the material world, one must first prove the existence of the self, which he posited as self-evident because â€Å"Cogito ergo sum† or â€Å"I think, therefore I am. † The reaction to these assertions is primarily split along two lines: skepticism and idealism. George Berkeley’s disagreement falls in the latter category, as he opined that Cartesian dualism implied that we cannot know anything beyond the sensations and ideas our mind believes to exist, while David Hume problematized why we believe in the existence of an external in the first place. John Locke developed a more nuanced understanding of the mind-self by defining it as a â€Å"conscious thinking thing† whose materiality or immateriality is irrelevant to acknowledging that it is conscious of sensation and emotion. Locke also posited that the body is also crucial to the formation of the mind-self, arguing that the mind-self is a tabula rasa, a blank slate shaped by experience, including natal sources of experience. Immanuel Kant developed an elaborate set of transcendental arguments and categories as a means f proving the existence of external reality. Essentially speaking, while sensations and perceptions do exist, they are meaningless without a unified comprehension of them. As such, experience is formed by the mind-self being able to cohere these impressions together as something meaningful. George Hegel challenged the understanding of truth as not just a concern with matters of substance, but matters of the subject perceiving and comprehending truth. As such, truth is just as contingent on the mind-self which thinks. Thus, unlike Berkeley, external realities are not just mere mental content, but an expression of thought itself. Descartes may have found few adherents during his time and years after, but his importance to succeeding philosophers who have attempted to deconstruct the contents of the mind and its relationship and understanding of the external world. In effect, he ushered in a fundamental level of doubt in assessing truth and knowledge so necessary in abnegating the kind of dogmatism which makes unquestioned acceptance of ‘common wisdom’ so problematic.

Business Structures Essay

If someone wants to start a business, that person would have to decide which structure he or she would want to use. To know what kind of structure he or she has to know what kind of business he or she is trying to run and who will run it with him or her. Structures range from sole proprietorships and partnerships to corporations. When companies first start up, they consider sole proprietorships or partnerships, but as they grow into larger companies, they become corporations. When someone first opens a business it may just be him or her, those companies consider sole proprietorships, meaning a business owned by one person. There are several advantages when running a sole proprietorship. First is it is the simplest type of business to start and run and also it is not regulated as much. Also, sole proprietorships pay lower income taxes compared to other business structures. Last, when a company is a sole proprietorship, decision-making rest on the owner’s shoulders but the owner keeps all profits (Films Media Group, 2011). Even though there are some very good advantages owning a sole proprietorship, there are also some disadvantages. The biggest advantage is also the biggest disadvantage, the bills, debts, and major obligations. If the owner does not pay the bills, the company cannot run. Another big disadvantage is the capital the business has. If the owner does not have some other capital invested into the company, the company will not grow. The last disadvantage is running the company when the owner leaves or dies. Because there is no one else with stock, the owner has to let the company go (Parrino, Kidwell, & Bates, 2012). The next business structure is a partnership, which consist of two or more owners that legally run the business together. With a partnership, the owners know what his or her position in the company is and how the profits would be split. There are two different partnerships; a general partnership and a limited partnership. The general partnership has the same advantages as a sole proprietorship, but has one more disadvantage. All owners have unlimited liability regardless of  the percenta ge in the company (Parrino, Kidwell, & Bates, 2012). To avoid the big issue with a general partner, the partner would sign into a limited partnership. In a limited partnership, the company can have general and limited partners. One or more general partner has unlimited liability while limited partners only deal with the obligations he or she provides. To qualify as a limited partner, he or she cannot engage in the managing of the business (Parrino, Kidwell, & Bates, 2012). The last business structure is the biggest and the last to get to. Large companies consider themselves to be corporations. Corporations consider themselves as a â€Å"person,† where the corporation can sue and also be sued, borrow money, and own assets like real estate. An advantage of a corporation is that the stockholders have a limited liability for all of the corporation’s obligations. Because the corporation is a â€Å"person,† the corporation is taxed as a â€Å"person† on the income it earns (Films Media Group, 2011). References Films Media Group (2011).

How to Write a Research Paper on Death Penalty

How to Write a Research Paper on Death Penalty Research Paper on Death Penalty How to start a research paper on death penalty Tips on how to start Making an outline Outline example Thesis statement examples Example of a death penalty research paper introduction How to write body paragraphs for the research paper on death penalty Tips on writing the body of the research paper First paragraph example Second paragraph example Third paragraph example How to write a conclusion of a research paper on death penalty Tips for writing a conclusion Example of a conclusion Revision tips How to start a research paper on death penalty In making a research paper, you should first come up with a topic. The topic should be relatable and informative. In choosing the topic, the author must consider the current events that are happening, the most talked about a topic that the readers would be interested to read. Death penalty is one of the biggest issues that have been revolving in the news for a very long time. Below are the tips on how to start writing your own research paper about the death penalty. Tips on how to start 1. Gather Information A student should first read journals and articles that are related to death penalty to be able to understand the topic well. An author should touch every aspect of the topic so when the writing starts not to state the false truth and to make the research paper or thesis reliable and factual. 2. Familiarize with the topic Familiarization will help an author see different sides of the topic death penalty. He or she can do this by watching videos of debate on death penalty. This way a student will understand the topic better and will be able to write the research paper in an objective manner. It is important to be objective in this kind of topic because the readers will have the freedom to take a side based on truths and evidences and not just based on the subjective point of view of the author. 3. Incorporate laws in the research Death penalty is a very sensitive topic and the information about it should be disseminated to the readers in a manner that is not derogatory to anyone. Reading law articles would be helpful in writing a research paper on this topic. This way the author will be informed of what laws are interconnected and related to death penalty. Making an outline An outline will serve as a guide for a research paper to be written in an organized manner so that the readers will understand it. This will help you organize your thoughts and ideas before writing. It is important to make an outline first before making the research paper to avoid errors and mixed information. The outline should consist of the following points: Thesis statement Supporting Arguments Body of the research paper of thesis Conclusion Outline example Thesis Title Abolish Death Penalty Thesis Statement Death penalty should be abolished because there is no assurance that the justice system is foolproof. It will only make the risks higher for innocent people to be punished in crimes they did not do. Supporting Arguments a) Killing people is inhumane and immoral. b) Death penalty is against human rights and very barbaric. C) The prisoners in the death row can possibly be innocent. Body of the Research Paper List of reasons why death penalty never fit a crime and why it is not morally accepted. Conclusion a) Supporting quote (relate back to intro): â€Å"The fear of death is the fear of life.† b) Restate thesis: Death penalty will not help people find justice; instead, it will only worsen the flaw in our justice system. Above is a sample outline that will guide you and give you an idea on how to make your own research paper. In your actual research paper or thesis, the body of the paragraph should consist of more than four paragraphs while the conclusion can be one long paragraph. Thesis statement examples In order to help you with your research paper, here are some thesis statement examples that will give you an idea of writing your own. The thesis statement is the problem that will be discussed in the entire research paper so if the statement is good the whole paper will be good. Death penalty should be abolished because of there is no assurance that the justice system is foolproof. It will only make the risks higher for innocent people to be punished for crimes they did not do. The approval of death penalty will only bring back the medieval way of punishing people in the most inhumane way. Death penalty is just like giving the politicians the right to murder anyone to settle political scores. Example of a death penalty research paper introduction In each given thesis statement examples above, there is a correspondent example introduction below to show you how to make an introduction. An introduction should always answer the questions why and how, why it should happen and how it would be accomplished. This will also help you come up with your own introduction in your research paper. The abolition of the death penalty should be pushed through so no one will be put into jail and die because of injustice. It will only happen if the government justice system will listen to the peoples cry and if they will consider human acts of punishment. In the medieval times, people were punished to death if they did something that is against the law. If we just continue this inhumane act of our ancestors, we will only prove that we have not evolved and stayed the same. In this present age, people are more open to change; if we continue the traditional punishment it only will show that there is no difference between the medieval people and us. Death penalty is an act that shows how the justice system will legalize a different kind of murder. The politicians who abuse their powers will be delighted to use death penalty as their scapegoat in murdering innocent people that come their way. How to write body paragraphs for a research paper on death penalty A body of the paper should contain supporting statements that will make the research paper convincing. Below are some tips on how to write the body of the paragraph. Tips on writing the body of the research paper You should start by writing your main and supporting ideas. The main ideas should always be in the first paragraph and the supporting ideas should be on the next paragraphs so the readers will understand the main topic. Each idea has to be explained and elaborated well for the readers to understand it clearly. You can also provide examples to give clarification to the readers. You should cite legitimate sources in your research paper. In finding supporting statements, you should make sure that you cited from books and journals that are used by lawyers and professionals. This will make your research paper authentic and reliable. If you want, you can also state news and article reviews as evidences of your statements. Conclusion in every paragraph is optional but it can also help the readers summarize the whole research paper. Below is an example of a short body of the paragraph to be your guide in writing your own research paper on death penalty. Thesis statement: Death penalty should be abolished because of its injustice. First paragraph example There is a number of reasons why death penalty never fit a crime. Even if a person did a crime, there is still no valid reason for anyone to sentence him death. The current justice system states that a person who committed the worst crime should be punished based on how worst his crime is. This seems to be completely illogical and contradictory. How can a person be accused of a crime that he did not do anything about? The answer is no one; therefore, the death penalty is not morally accepted. Second paragraph example In terms of morality, those people who receive the death penalty are usually not physically or mentally fit to receive the punishment. Some are suffering from mental disabilities that have caused them commit such crimes. Twelve percent of people who are on the death row are proven mentally retarded making them not fit to the punishment of death. Third paragraph example The electric chair used for killing people who are in the death row has reported to fail and causes multiple attempts of execution before the prison actually die. Even the lethal injection used in modern execution sometimes fails and makes the prisoners execution slower and painful. Things like this prove that there is a serious flaw in the justice system. How to write a conclusion of a research paper on death penalty A conclusion serves as the summary of a research paper. It will also include your stand on the topic, whether you agree or disagree. It is important to include a conclusion in every research paper because it will be the closing paragraph and it indicates the end of the research paper. Tips for writing a conclusion A conclusion should have a brief summary of a body of a research paper. You can use a quotation related to death penalty to capture the attention of your readers until the end. Recall some important points in the body of the research so that the information will be refreshed in the mind of the readers. Compare your topic with other. In this way, you will show the readers that your research paper is broad and universal. Lastly, give recommendations. This will make your conclusion more professional. To complete your guide in writing a research paper on death penalty, below is an example of a conclusion that you can use as to help you write your own conclusion. Example of a conclusion A wise man once said, â€Å"The fear of death is the fear of life.† Death penalty will not help people find justice; instead, it will only worsen the flaw in our justice system. The people who commit crimes should receive punishment but not in the form of death. Their lives should be valued no matter what mistake they have made. They should learn their lesson while in jail but they should never suffer death as a form of payment for their crimes. Revision Tips After submitting your final thesis or research paper your professor/instructor will give advice on how you can improve your research paper. Below are some tips on how you will revise your paper fast and efficiently. List down corrections When your professor gives back your thesis or research paper for the revision you must first check what are the parts that need revision. Once you finish scanning the paper for all the revisions needed you can already start revising. The best technique to make revising fast is to go page by page. When you do this, you can make sure that there is no single word in the research paper that you have not seen. Consider feedback Your professor aims to help you in your research paper so you should consider all his notes and advice in improving your research paper. Accept that your paper is not perfect and the advice that he or she gave you is important and will be so much help. Ask for help When you are having a hard time correcting your own work it is okay to ask someone for help. It may be your classmate, brother, sister, or parents, as long as they are willing and knowledgeable you should always consider their help. Sometimes we cannot see our own mistakes, so having another person check your work and give comments about it will not only improve the research paper it will also give you ideas on how to make it better the next time you make another research paper.

State of Matter Definition - Chemistry Glossary

State of Matter Definition - Chemistry Glossary Physics and chemistry both study matter, energy, and interactions between them. From the laws of thermodynamics, scientists know matter can change states and the sum of the matter and energy of a system is constant. When energy is added or removed to matter, it changes state to form a state of matter. A state of matter is defined as one of the ways in which matter can interact with itself to form a homogeneous phase. State of Matter vs Phase of Matter The phrases state of matter and phase of matter are used interchangeably. For the most part, this is fine. Technically a system can contain several phases of the same state of matter. For example, a bar of steel (a solid) may contain ferrite, cementite, and austenite. A mixture of oil and vinegar (a liquid) contains two separate liquid phases. States of Matter In everyday life, four phases of matter exist: solids, liquids, gases, and plasma. However, several other states of matter have been discovered. Some of these other states occur at the boundary between two states of matter where a substance doesnt really display the properties of either state. Others are most exotic. This is a list of some states of matter and their properties: Solid: A solid has a defined shape and volume. Particles within a solid are packed very close together fixed in an ordered arrangement. The arrangement may be sufficiently ordered to form a crystal (e.g., NaCl or table salt crystal, quartz) or the arrangement may be disordered or amorphous (e.g., wax, cotton, window glass). Liquid: A liquid has a defined volume but lacks a defined shape. Particles within a liquid are not packed as close together as in a solid, allowing them to slide against each other. Examples of liquids include water, oil, and alcohol. Gas: A gas lacks either a defined shape or volume. Gas particles are widely separated. Examples of gases include air and the helium in a balloon. Plasma: Like a gas, a plasma lacks a defined shape or volume. However, the particles of a plasma are electrically charged and are separated by vast differences. Examples of plasma include lightning and the aurora. Glass: A glass is an amorphous solid intermediate between a crystalline lattice and a liquid. It is sometimes considered a separate state of matter because it has properties distinct from solids or liquids and because it exists in a metastable state. Superfluid: A superfluid is a second liquid state that occurs near absolute zero. Unlike a normal liquid, a superfluid has zero viscosity. Bose-Einstein Condensate: A Bose-Einstein condensate may be called the fifth state of matter. In a Bose-Einstein condensate the particles of matter stop behaving as individual entities and may be described with a single wavefunction. Fermionic Condensate: Like a Bose-Einstein condensate, particles in a fermionic condensate may be described by one uniform wavefunction. The difference is the condensate is formed by fermions. Because of the Pauli exclusion principle, fermions cant share the same quantum state, but in this case pairs of fermions behave as bosons. Dropleton: This is a quantum fog of electrons and holes that flow much like a liquid. Degenerate Matter: Degenerate matter is actually a collection of exotic states of matter that occur under extremely high pressure (e.g., within the cores of stars or massive planets like Jupiter). The term degenerate derives from the way matter can exist in two states with the same energy, making them interchangeable. Gravitational Singularity: A singularity, like at the center of a black hole, is not a state of matter. However, it bears noting because its an object formed by mass and energy that lacks matter. Phase Changes Between States of Matter Matter can change states when energy is added or removed from the system. Usually, this energy results from changes in pressure or temperature. When matter changes states it undergoes a phase transition or phase change. Sources Goodstein, D. L. (1985). States of Matter. Dover Phoenix. ISBN 978-0-486-49506-4.Murthy, G.; et al. (1997).

The Image of Iron Man Essay Example | Topics and Well Written Essays - 1000 words

The Image of Iron Man - Essay Example To many, Iron man remains known as a superhero and therefore a number of items need always to be included in the making of his art work. Iron man hence represents power, intelligence, confidence and indestructibility. Iron man remains as a representative of symbol of power. One day, while visiting an art gallery of Iron man in the neighborhood, I managed to come across the comic galleries of Iron man. Meeting one’s eyes from far, one could always recognize Iron man from the red iron suit that he constantly has. Red being a symbol of danger, always ensures that it attracts people’s attention toward that direction. In addition, the eyes of Iron man are always depicted as constantly glowing hence remitting an eminence of power being driven from a source. The bright light that constantly surrounds the background of Iron man in many of the comics depicts the nature of a superhero. In one of the comic books, one could clearly see the contrast between villains and Iron Man sim ply by the play of light and darkness. Iron man always stands out in a crowd when looked from far due to his bright clothing and attractive outfit. In addition, Iron man on art work and comics always becomes depicted as an intelligent being. In some of the posters, Iron man often has this gaze that depicts a nerd at work. The makers of Iron man used incredible thinking capacity to come up with an intelligent iron suit that made the character a great superhero. From whatever Iron man often says in the comics, one could realize that he often spoke of aspects related to advanced technology. In addition, the owner and maker of the designer iron suit when not at work, is always depicted as being involved in activities that require great intelligence. Furthermore, Iron man depicts a sign of confidence to many that view his art work. In looking at one of the posters of iron man in the gallery store, one is always met by the sharp gaze of Iron man looking straight at some one. It is only co nfident people that manage to make such gaze to individuals. In addition, looking at the Iron man’s body physic, one could realize that on standing, everything about the superhero was so perfect. It is via the confidence that such superhero gains popularity among children and adults interested in those comic books and posters. In having a face mask with a single expression on its face, confidence, one always remains admiring such a comic. In one of the posters, one could see Iron man blasting some form of energy from his hands to a bunch of villains. His confidence remains as what derives him to do whatever he does best, save other people at the end of the day from the hands of the villains. The expression of confidence from the way the robot frame of iron man walks while approaching its enemies clearly depicts confidence of the highest level. The character in being behind an iron armor, the character believes he could face any villain he came across. Furthermore, in the pict ures depicting Iron man as flying, his head remains always ahead while his hands sideways facing backwards, a symbol of great confidence in whatever one was doing. Iron man in some of the comic books and posters also depicts a sense of indestructibility. In wearing an iron suit, one always felt confident that nothing would harm the person controlling the iron suit. In addition, in one of the comics, one could see a picture of iron man being struck by a villain, but
