The Process Control Management In Linux Information Technology Essay

The Process Control Management In Linux Information Technology Essay Linux started to create in 1991 when a Finnish understudy, Linus Torvalds, composed a modest independent portion for the 80396 processors. Linux source code was accessible free on the web. Because of that Linux created by numerous clients from around the globe. Linux is a free working framework and present day dependent on UNIX measures. A total Linux framework contains numerous parts that were grown freely of Linux. The center of Linux working framework bit is totally unique, yet it permits many existing free UNIX programming to run, bringing about a total UNIX perfect working framework liberated from exclusive code. Presentation A procedure is the fundamental setting between all client action and client demand inside the working framework. Linux needs to utilize a procedure model natural to different variants of UNIX to be good with them. Linux works same as UNIX and contrastingly hardly any key spots. Segment 1: Operating Systems Procedure control the board in Linux Procedures and Threads Linux readies a fork () framework call with the standard usefulness of duplicating a procedure. Linux give capacity to make strings through the clone () framework call. In any case, Linux can't stamp as various among procedures and strings. All things considered, Linux for the most part utilizes the term task when applying to a progression of control inside a program. At the point when clone () is mentioned, it is passed a gathering of flagellate that decide how much sharing is to happen between the parent and kid obligations. In this manner, if clone () is affirmed the banners CLONE_FS, CL0NE_VM, CLONE_SIGHAND, and CLONE_FILES, the parent and youngster obligations will have a similar record framework data, a similar memory space, a similar sign handlers, and a similar arrangement of open documents. Utilizing clone () in this style same as making a string in different frameworks, since the parent obligation imparts the greater part of assets to youngster obligation. The absence of distinction among procedures and strings may be conceivable on the grounds that Linux doesn't hold a whole procedure setting inside the fundamental procedure information structure. It keeps the setting inside self-sufficient sub-settings. The procedure information structure essentially contains pointers to these different structures, so every number of procedures capable effectively shares a sub-setting through highlighting a similar sub-setting as appropriate. The contentions to the clone () framework order it which sub-settings to duplicate, and which to share, when it makes another procedure. The new procedure continually is given another character and another planning setting; as per contentions passed, in any case, it might either make new procedure utilize a similar sub-setting information structures being utilized by the parent. The fork () framework call si unique instance of clone () that copy all sub-setting and nothing to share. Procedure Scheduling Booking is designating CPU time to various errands inside a working framework. Generally, being the running and hindering of procedure are ordinary pondering planning, yet another part of booking is additionally essential to Linux which is running of the different bit assignments. Part assignments encompass the two errands that are mentioned through a running procedure and undertakings which execute inside for the benefit of gadget driver. Linux has two independently unique procedure booking calculations. Initial one is a period sharing calculation for reasonable, preemptive planning inside numerous procedures; the subsequent one is intended for continuous undertaking, where specific needs are a higher priority than decency. The booking calculation utilized for schedule, time-sharing assignments got a significant update with variant 2.5 of the piece. Before form 2.5, the Linux piece made a variety of the planning calculation in customary UNIX. Issues with the customary UNIX are among different issues that it doesn't offer adequate help for SMP frameworks and that it doesn't scale very well as the quantity of undertakings on the framework develops. The redesign of the scheduler piece with rendition 2.5 presently gives a planning calculation that runs in steady time without thought of the quantity of assignment on the framework. The new procedure scheduler likewise offers diminished help for SMP, including processor fondness and burden adjusting, other than keeping up decency and intuitive undertakings supporting. The Linux scheduler is a specific, need based calculation with two need goes independently: a constant range from 0 to 99 and a pleasant worth running from 100 to 140. These two territories map into all inclusive need conspire through numerically lower esteems show higher needs. Linux doles out higher-need assignments longer time quanta and the other way around. Because of remarkable nature of the scheduler, this is appropriate for Linux. A run capable assignment is considered meet all requirements for execution on the CPU while it has time staying in its time cut. At the point when an assignment has used its time cut, it is viewed as lapsed and isn't qualified for twice execution till every single other errand have likewise depleted their time quanta. The portion bolster s a rundown of all run-capable undertakings in a run-line information structure. Because of its help for SMP, every processor keeps up its own run-line and timetables itself freely. Each run-line incorporates two need clusters which are dynamic and terminated. The dynamic cluster contains every single terminated undertaking and every one of these need exhibits contains a rundown of assignments ordered by need. The scheduler chooses the assignment with the most elevated need from the dynamic exhibit for execution on the CPU. On some multiprocessor machines, this implies every processor on the single machine is booking the most elevated need task from its own run-line structure. So when all errands have used their time cuts which is the dynamic exhibit is vacant, the two need clusters are supplanted as the terminated exhibit turns into the dynamic exhibit and the other way around. Assignments are dispensed unique needs that depend on the decent worth less or in addition to until esteem 5 dependent on task intuitiveness. Regardless of whether a worth is deducted or included from a pleasant worth errand relies upon the assignment intelligence. A task㠢㠢‚⠬㠢„â ¢s intuitiveness is controlled by to what extent it has been resting during hanging tight for I/O. Errands that are all the more imparting regularly have longer rest times as are all the more most likely to have an alteration closer to - 5, as the scheduler supports such intelligent undertakings. in a contrary way assignments with shorter rest times are as a rule more CPU-bound and accordingly will have their needs diminished. The recalculation of dynamic need task happens when the undertaking has drained its time quantum and is to be moved to the terminated cluster. Along these lines, when the two exhibits are traded, the sum total of what errands have been doled out in the new cluster to new needs and comparative time cut. Ongoing planning in Linux is more straightforward still. Linux plays out the two ongoing booking classes required by POSIX.1b: first come, first served (FCFS) and cooperative effort. Each procedure has a need extra to its planning class in them two. Procedures of various needs may be rivaled each other somewhat in booking of time sharing; continuously planning, notwithstanding, the scheduler more often than not runs the procedure with the most elevated need. Among equivalent need forms, it runs the procedure which has been standing by longest. The main distinction between cooperative effort and FCFS planning is that FCFS forms keep on running till they either exit or square, yet a cooperative procedure will be procured inevitably and will be moved as far as possible of the booking line, subsequently, equivalent need cooperative procedures will naturally time-share between themselves. Not at all like common time-sharing assignments, continuous undertakings are apportioned static needs . Continuous Linux planning is delicate as opposed to hard constant. The scheduler gives severe assurances about the overall needs of constant procedures, alongside the portion doesn't offer any ensures that how rapidly a continuous procedure will be booked once that procedure become run capable. Segment 2: Computer Systems Architecture Chip Single-Processor Systems The majority of PC frameworks utilize a solitary processor. The decent variety of single-processor frameworks might be amazing, in any case, since these PC frameworks extend from PDAs through centralized computer frameworks. There is one principle CPU fit for playing out a broadly useful guidance set on a solitary processor framework that including guidelines from client forms. Practically all PC frameworks have other specific reason processors also. They may come through gadget explicit processors, for instance designs controllers, plate and console; or, on centralized computers, they may originate from of increasingly broad processors, for example, I/O processors which move information rapidly among the part of the framework. These particular reason framework processors run a CPU constrained guidance set in more often than not and don't run client forms. Some of the time they are controlled by the working framework, in that the working framework sends them rapidly data about their next assignment and afterward screens their status then again. For example, a plate controller microchip in a framework gets an arrangement of solicitations from the fundamental CPU and executes its own circle line and booking calculation. This course of action discharges the fundamental CPU of the overhead of the circle booking. All the PCs contain a specific microchip in the console to change the keystrokes into code to be dispatched to the CPU. In certain frameworks unique reason processors are low-level fixing incorporated with the system㠢㠢‚⠬㠢„â ¢s equipment. The working framework can't discuss effectively with these sorts of processors; they carry out their responsibility autonomously. The utilizati on of particular reason chip is common and doesn't change a solitary processor framework into a multiprocessor. Be that as it may, the framework is a solitary processor framework if there is just one universally useful CPU. Multiprocessor Systems Albeit single p

How to Control Compulsive Lying When You Have an Addiction Addiction Drug Use Print How to Control Compulsive Lying When You Have an Addiction When Other People Just Dont Understand By Elizabeth Hartney, BSc., MSc., MA, PhD Elizabeth Hartney, BSc, MSc, MA, PhD is a psychologist, professor, and Director of the Centre for Health Leadership and Research at Royal Roads University, Canada. Learn about our editorial policy Elizabeth Hartney, BSc., MSc., MA, PhD Updated on May 05, 2019 Lying to your doctor is not a smart move. PhotoAlto/Eric Audras / Getty Images More in Addiction Drug Use Cocaine Heroin Marijuana Meth Ecstasy/MDMA Hallucinogens Opioids Prescription Medications Alcohol Use Addictive Behaviors Nicotine Use Coping and Recovery Lying about your addiction, particularly if your addictive behavior is illegal, can become second nature. It can even give a sense of power â€" “I got away with that.” But lying is extremely damaging to relationships, family members are often aware that they are being lied to, and many people with addictions would prefer to be more truthful, but just don’t know how. Try following these tips on controlling compulsive lying. They will give you some ideas to get you started on building trust and easing your conscience. 1. Stop Lying to Yourself This might seem like a strange tip, but research shows that people with addictions actually do lie to themselves in a number of different ways. Tip: Lying to yourself may be making your addiction worse. Being honest with yourself is the first step in becoming honest with others. 2. Know Who You Can Trust â€" When It’s In Your Best Interests There are some people who will always want what is in your best interests, and they are a great place to start when being truthful is new. They include your doctor, and any counselors or therapists you may be seeing. These people are trained to understand and help people with addictions, but they can’t help you if you don’t tell them what is really going on. In fact, lying to your doctor about your addiction could even put you at risk of getting advice or a prescription that is the opposite of what you actually need. This could even cause you harm. Tip: Be honest with your doctor. Even if you don’t tell them everything, at least answer their questions truthfully. 3. It’s None of Their Business â€" Or Is It? Everyone has the right to privacy. The fact that you have an addiction is your private business, and you should be in control of who has access to that information. But in some cases, your addiction might also impact someone, making it their business, too. Before writing off another persons right to know the truth about your addiction, think about whether it has any impact on them. Members of your immediate family, for example, will very likely be impacted by your addiction, even if it is simply by your lack of availability for your relationship with them. Anyone who may be affected by the consequences of your addiction also has a right to know the truth, including anyone you have hurt while under the influence. Tip: If you think your addiction may impact another person, consider telling them the truth. 4. They Can’t Cope With The Truth â€"- But Maybe They Are Already You may think you have to keep your addictive behavior secret from people you are close to, such as your partner, adult children, or your parents, because you think it would be more than they could cope with. Although they are likely to worry, in reality, they would have a much harder time coping with the serious consequences of your addiction, such as legal and health problems, if they were unaware of your addiction. However, you should be careful in talking to young children about addictions, and this should ideally be done with the support of a trained family therapist. Having a parent who uses alcohol or drugs makes it more likely that your child will use these substances, so be careful about disclosure and particularly to never use alcohol or drugs in front of them, or offer them alcohol or drugs. Tip: Even if you don’t proactively tell your partner, adult child or parent about your addiction, understand that if they ask about it, they can probably cope with a truthful answer. 5. All They Do Is Criticize Me â€" But They Could Just Listen The chances are that the news of your addiction will cause some initial upset. You may, indeed, be subject to criticism. You may also hear some negative comments which are not criticism, but which you perceive as such. It can be helpful to see the difference. It can be hard to know how to talk to someone with an addiction, especially if there have been past lies and hurts. If the person in question cares about you, they will want what is best for you, which is that you are well and happy. They may have a period of adjustment as they accept your addiction, but they may also be your greatest source of support through overcoming your addiction. Also, knowing what is going on can help family members find their own support. Tip: If you expect criticism, make a point of reflecting on your own behavior in case they have a point. You can also ask your loved one to listen without criticizing. 6. They Don’t Understand â€" But Maybe They Could With Help Perhaps your loved one is not as worldly-wise as you, but they might be. And although you might think that understanding someone with an addiction is something they are not capable of, often people with addictions are surprised at how well their loved ones understand what they are going through. On the other hand, they may have a hard time understanding, but after a period of adjustment, may well do all they can to understand. Many treatment services now offer education and support sessions for family members for precisely this reason. After learning about addiction, family members can be extremely supportive. Tip: Give your loved one the chance to understand by educating them about your condition. 7. I Don’t Care About Them â€" But Maybe I Should Sometimes people with addictions get into relationships with other people for what they can get out of it â€" money, drugs, sex and social status are all common motivators. But by being in exploitative relationships with other people, you are setting yourself up for more shame and regret than you realize. You may not feel you are doing the other person any harm. You may even feel they are getting as much out of the relationship as you are. But the time you spend exploiting them is time neither of you will ever get back. You are essentially depriving them of the chance to have a genuine relationship with someone who really cares about them. When the relationship ends, you will be left with the shame of knowing you have spoiled part of someone else’s life. These shameful feelings are very unpleasant, and can often make an addiction worse, as you attempt to escape them through addictive behavior. Tip: Think about whether you want the responsibility of having impacted negatively on someone else’s life. 8. Allow Your Loved One the Gift of Forgiveness By shackling your relationship with secrets and lies, you deny your loved one the opportunity to forgive you. They may be well aware of your lies, or at least suspect, but they can’t be freed from their hurt and resentment unless they know the truth. Then they have the option to forgive you for past lies and hurts. Of course, having your loved one’s forgiveness will probably feel pretty good to you too. Tip: Apologize if you have hurt someone you love. They might just forgive you.

Potential Medical Benefits of Embryonic Stem Cells

Today’s society has involved many scientific advances and beneficial research. Scientists all over the world have been doing recent studies on embryonic stem cells. Embryonic stem cells are the cells that aid the process of child growth while in the womb. These cells have a specific function to reproduce into any body part, such as a heart or major organ to hair or something not so major. Research shows that these cells have many potential medical benefits in the future. Embryonic stem cell research should continue to be pursued in society today. Embryonic stem cell research has led to medical benefits to aid in curing diseases and many cancer cases that have grown in today’s society. Tissues throughout the body have a specific single layer of cells that can regenerate daughter cells. These daughter cells, or embryonic cells, have the capabilities to regenerate and build tissues or organs. These cells can aid in a lifelong regeneration process for tissues throughout th e body. In vitro studies have shown that these cells can be placed in a specific area where there is large amounts of tissue damage due to injury or disease and completely rebuild this tissue into a completely new, fully functioning tissue. (Weissman, 2005, p. 1). However, people will argue the fact that embryonic stem cells have not been cleared to work in the human body.

The Importance Of The National Association For Young...

The History of NAEYC By: Katie A. Wnukoski ECED 776 Dr. Shaffer 10/13/2016 Throughout our career as childhood educators, we observe the significance of the National Association for Young Children or NAEYC. It is recognized as â€Å"the nation’s premier organization for early childhood professionals-setting research based standards and providing resources to improve early childhood program quality† (Copple NAEYC, 2001) for teachers, students, and families. Despite exercising the knowledge of what NAEYC means for our classrooms and the students in them, some may not know who or how the organization was founded. Knowing the background of NAEYC is important because it has a reputable history of providing universities and educators with high quality, researched, information. In order to ascertain a further purpose to why these standards matter and the importance of NAEYC in education, we must learn its history and its founders. The standards written for NAEYC have been chosen through the appropriate research, to suite multiple situations and prac tices. By learning more in depth of the theorists and researchers that have made NAEYC what it is today, allows us to see origins of each standard and how they have developed from theory, into a standard in today’s education.

Weathering and Erosion Free Essays

Weather is the state of the atmosphere at a given time and place, with respect to variables such as temperature, moisture, wind velocity, and barometric pressure. Weather can be classified as day to day temperature and precipitation activity, where climiate is average atmospheric conditions over longer periods of time. Weather occurs from temperature and moisture differences between one place and another. We will write a custom essay sample on Weathering and Erosion or any similar topic only for you Order Now These differences can occur due to the sun angle at any particular spot. The strong temperature contrast between polar and tropical air gives rise to the jet stream. Weather systems in the mid-latitudes, such as â€Å"extratropical cyclones†, are caused by instabilities of the jet stream flow. Because the Earth’s axis is tilted relative to its orbital plane, sunlight is pointed at different angles at different times of the year. On Earth’s surface, temperatures usually range from 0-100 degrees farenheit annually. Over thousands of years, changes in Earth’s orbit affect the amount and distribution of solar energy received by the Earth and influence long-term climate Surface temperature differences in turn cause pressure differences. Higher altitudes are cooler than lower altitudes due to differences in compressional heating. Weather forecasting is the application of science and technology to predict the state of the atmosphere for a future time and a given location. The atmosphere is a chaotic system, so small changes to one part of the system can grow to have large effects on the system as a whole. Human attempts to control the weather have occurred throughout human history, and there is evidence that human activity such as agriculture and industry has inadvertently modified weather patterns. Studying how the weather works on other planets has been helpful in understanding how weather works on Earth. A famous landmark in the Solar System, Jupiter’s Great Red Spot, is an anticyclonic storm known to have existed for at least 300 years. However, weather is not limited to planetary bodies. A star’s corona is constantly being lost to space, creating what is essentially a very thin atmosphere throughout the Solar System. The movement of mass ejected from the Sun is known as the solar wind. On Earth, common weather phenomena include wind, cloud, rain, snow, fog and dust storms. Less common events include natural disasters such as tornadoes, hurricanes, typhoons and ice storms. Almost all familiar weather phenomena occur in the troposphere (the lower part of the atmosphere). Weather does occur in the stratosphere and can affect weather lower down in the troposphere, but the exact mechanisms are poorly understood. Weather occurs primarily due to density (temperature and moisture) differences between one place to another. These differences can occur due to the sun angle at any particular spot, which varies by latitude from the tropics. In other words, the farther from the tropics you lie, the lower the sun angle is, which causes those locations to be cooler due to the indirect sunlight The strong temperature contrast between polar and tropical air gives rise to the jet stream. Weather systems in the mid-latitudes, such as extratropical cyclones, are caused by instabilities of the jet stream flow (see baroclinity). Weather systems in the tropics, such as monsoons or organized thunderstorm systems, are caused by different processes. Because the Earth’s axis is tilted relative to its orbital plane, sunlight is incident at different angles at different times of the year. In June the Northern Hemisphere is tilted towards the sun, so at any given Northern Hemisphere latitude sunlight falls more directly on that spot than in December (see Effect of sun angle on climate). This effect causes seasons. Over thousands to hundreds of thousands of years, changes in Earth’s orbital parameters affect the amount and distribution of solar energy received by the Earth and influence long-term climate. see Milankovitch cycles). Uneven solar heating (the formation of zones of temperature and moisture gradients, or frontogenesis) can also be due to the weather itself in the form of cloudiness and precipitation. Higher altitudes are cooler than lower altitudes, which is explained by the lapse rate. On local scales, temperature differences can occur because different surfaces (such as oceans, forests, ice sheets, or man- made objects) have differing physical characteristics such as reflectivity, roughness, or moisture content. Surface temperature differences in turn cause pressure differences. A hot surface heats the air above it and the air expands, lowering the air pressure and its density. The resulting horizontal pressure gradient accelerates the air from high to low pressure, creating wind, and Earth’s rotation then causes curvature of the flow via the Coriolis effect. The simple systems thus formed can then display emergent behaviour to produce more complex systems and thus other weather phenomena. Large scale examples include the Hadley cell while a smaller scale example would be coastal breezes. The atmosphere is a chaotic system, so small changes to one part of the system can grow to have large effects on the system as a whole. This makes it difficult to accurately predict weather more than a few days in advance, though weather forecasters are continually working to extend this limit through the scientific study of weather, meteorology. It is theoretically impossible to make useful day-to-day predictions more than about two weeks ahead, imposing an upper limit to potential for improved prediction skill. Chaos theory says that the slightest variation in the motion of the ground can grow with time. This idea is sometimes called the butterfly effect, from the idea that the motions caused by the flapping wings of a butterfly eventually could produce marked changes in the state of the atmosphere. Because of this sensitivity to small changes, it will never be possible to make perfect forecasts. Weather has played a large and sometimes direct part in human history. Aside from climatic changes that have caused the gradual drift of populations (for example the desertification of the Middle East, and the formation of land bridges during glacial periods), extreme weather events have caused smaller scale population movements and intruded directly in historical events. One such event is the saving of Japan from invasion by the Mongol fleet of Kublai Khan by the Kamikaze winds in 1281. French claims to Florida came to an end in 1565 when a hurricane destroyed the French fleet, allowing Spain to conquer Fort Caroline. More recently, Hurricane Katrina redistributed over one million people from the central Gulf coast elsewhere across the United States, becoming the largest diaspora in the history of the United States. Weather forecasting is the application of science and technology to predict the state of the atmosphere for a future time and a given location. Human beings have attempted to predict the weather informally for millennia, and formally since at least the nineteenth century. Weather forecasts are made by collecting quantitative data about the current state of the atmosphere and using scientific understanding of atmospheric processes to project how the atmosphere will evolve. Once an all-human endeavor based mainly upon changes in barometric pressure, current weather conditions, and sky condition, forecast models are now used to determine future conditions. Human input is still required to pick the best possible forecast model to base the forecast upon, which involves pattern recognition skills, teleconnections, knowledge of model performance, and knowledge of model biases. The chaotic nature of the atmosphere, the massive computational power required to solve the equations that describe the atmosphere, error involved in measuring the initial conditions, and an incomplete understanding of atmospheric processes mean that forecasts become less accurate as the difference in current time and the time for which the forecast is being made (the range of the forecast) increases. The use of ensembles and model consensus helps to narrow the error and pick the most likely outcome. There are a variety of end users to weather forecasts. Weather warnings are important forecasts because they are used to protect life and property. Forecasts based on temperature and precipitation are important to agriculture, and therefore to commodity traders within stock markets. Temperature forecasts are used by utility companies to estimate demand over coming days. On an everyday basis, people use weather forecasts to determine what to wear on a given day. Since outdoor activities are severely curtailed by heavy rain, snow and the wind chill, forecasts can be used to plan activities around these events, and to plan ahead and survive them. Studying how the weather works on other planets has been seen as helpful in understanding how it works on Earth. Weather on other planets follows many of the same physical principles as weather on Earth, but occurs on different scales and in atmospheres having different chemical composition. The Cassini–Huygens mission to Titan discovered clouds formed from methane or ethane which deposit rain composed of liquid methane and other organic compounds. Earth’s atmosphere includes six latitudinal circulation zones, three in each hemisphere. In contrast, Jupiter’s banded appearance shows many such zones, Titan has a single jet stream near the 50th parallel north latitude, and Venus has a single jet near the equator. Weather events influence biological processes on short time scales. For instance, as the Sun rises above the horizon in the morning, light levels become sufficient for the process of photosynthesis to take place in plant leaves. Later on, during the day, air temperature and humidity may induce the partial or total closure of the stomata, a typical response of many plants to limit the loss of water through transpiration. More generally, the daily evolution of meteorological variables controls the circadian rhythm of plants and animals alike. Living organisms, for their part, can collectively affect weather patterns. The rate of evapotranspiration of forests, or of any large vegetated area for that matter, contributes to the release of water vapor in the atmosphere. This local, relatively fast and continuous process may contribute significantly to the persistence of precipitations in a given area. As another example, the wilting of plants results in definite changes in leaf angle distribution and therefore modifies the rates of reflection, transmission and absorption of solar light in these plants. That, in turn, changes the albedo of the ecosystem as well as the relative importance of the sensible and latent heat fluxes from the surface to the atmosphere. For an example in oceanography, consider the release of dimethyl sulfide by biological activity in sea water and its impact on atmospheric aerosols.

Wilamenah Merriam Mrs. Plowmen American Literature 15 September 2017 Rhetorical Analysis John F. Kennedys' speech "Ich bin ein Berliner", was delivered in West Berlin during the Cold War. JFK delivered that speech to advocate for peace. He believed everyone should be able to experience peace. During this time period, democrats and communist were divided which caused some tension. In his speech, JKF argued the wall dividing Berlin was separating people who wanted to be together. In his speech, he uses logos, pathos, and ethos to advocate for peace during the cold war. JFK uses logos in in speech multiple times. He states, "Real, lasting peace in Europe can never be assured as long as one German out of four is denied the elementary right of free men, and that is to make a free choice" ( "Ich bin ein Berliner"). This appeals to logic because it is persuading the audience by reason, that all can not be free if some are still not, showing a flawed logic in the wall. Further in the speech, JFK states, "Freedom has many difficulties and democracy is not perfect. But we have never had to put a wall up to keep our people in -- to prevent them from leaving us" ( "Ich bin ein Berliner"). This appeals to logos because it is using the logic that nothing is perfect, but nothing should be so bad to have to build a wall to keep people in one place. The use of ethos in the speech is an underlining theme. In his speech, JKF talks about the many consequences of the separation and the non-peaceful environment of Germany. He states," ..an offense not only against history but an offense against humanity, separating families, dividing husbands and wives and brothers and sisters, and dividing a people who wish to be joined together"( "Ich bin ein Berliner"). This appeals to emotions because everyone has family, and it put them in the position of imagining them separated from their family members and friends. He also states," . I know of no town, no city, that has been besieged for 18 years that still lives with the vitality and the force, and the hope, and the determination of the city of West Berlin" ( "Ich bin ein Berliner"). This appeals to the emotional side because it is telling the people that the city of West Berlin still hasn't lost their hope through the tough times of being separated from their friends and families. JFK also uses ethos in his speech along with logos and pathos. He talks about the rights of freedom and lasting peace of individuals. He states,"this generation of Germans has earned the right to be free, including the right to unite their families and their nation in lasting peace, with good will to all people"( "Ich bin ein Berliner"). This use of ethics ties back to the idea of the United States freedom that all men are created equal and have the right to freedom. He also talks about the given rights, peace, and goodwill towards all people which appeals to most people's ethics on unalienable rights. In conclusion, JKF's speech, "Ich bin ein Berliner", JFK argues for peace during the cold war by uses logos, pathos, and ethos to appeal to all different kinds of people to prove one point. The use of these devices helps prove an effective argument for the peace of the nation. The argument shown in this speech helps make people motivated to make a change in their society and push for what they know is right ethically, logically, and emotionally. Kennedy, John F.
