Type Of Microprocessors For Desktop Computer Science Essay This reports body is divided into two main sections. One section will explain a different topic from another. In each section, there are introductions to the topic, explanation, conclusion, and FAQ (Frequently Asked Questions). Section one will explain about memory management in operating system, which is Windows 7 32-bit. There are 2 memories that will be covered in this section including their technology in management also, physical memory and virtual memory. Analysis about limitations of the technologies and solutions to overcome them are included. Section two will cover about the design and performances of microprocessors. There is a list, consisted of 5 major trends affecting the microprocessor performance. Besides that, microprocessors are explained further through the types of modern microprocessor, which are separated into the usage in desktop, laptop, or server. The differences in design and features between the desktops, laptops, servers, and embedded systems are included at the end of the section. Section 1 (One) : Operating System Memory Management Introduction Windows 7 is the latest release of operating system which is introduced by Microsoft in July of 2009 It was preceded by Windows XP and Windows Vista. The purpose of the development of Windows 7 is on personal computers, including desktops, laptops, and tablet PCs. Windows 7 has not so much difference from predecessor Windows Vista. Windows 7 adapts some features that Windows Vista already introduced before, but 7 was intended to be more focused on improvement compatibility with applications and hardware with which Vista already compatible. Microsoft also always tries to improve security in each generation of Windows operating system. Since the generation of Windows Vista, it actually works. Windows operating systems have become more secure and more susceptible from viruses, especially Windows 7. This report will cover about Windows 7 32-bits memory management. This report will also explain further about Windows 7s management of physical memory and virtual memory. Memory Management Memory management is planned organization of programs and data into the memory. The objectives of memory management are not only to easier for programs to find space to be loaded and executed, as simple as possible, but also to maximize the use to reduce memory waste. There are two kinds of memory management, physical memory management and virtual memory management. Physical memory, known as RAM (Random Access Memory), is a form of dynamic computer storage. RAM allows the computer to store data for quick retrieval and run multiple programs at once. This memory has capacities and types which vary and will depend on the computers motherboard. Virtual memory on the other hand, has the work to compensate the lack of RAM needed to run an application or an operation. Virtual memory combines the computers RAM and the temporary space on hard disk together. When RAM runs low, virtual memory will move data from RAM to a space called a paging file. Then it moves the data to and from the paging file to free up RAM. Physical Memory Management Physical memory  management is a memory management technique that uses RAM (Random Access Memory) as its resource to handle all of the processes in the computer. So, all the processes will be divided into smaller parts and they will be loaded into physical memory that later will be processed. System Paging In System Paging, the operating system or Windows will retrieve the data from secondary storage called as pages, and then Windows will use the paging file as a temporary storage for the memory dump. As the system reboots, Windows will copy the memory dump into a separate file, and then frees the space that was used before. Since Windows Vista onwards, Windows operating system had been improved a lot better in its physical memory management as in improvements for input-output speed and performance and more efficient and effective memory management. Windows 7 implements a technique related to physical memory management which is called Microsoft SuperFetch. Microsoft SuperFetch Microsoft SuperFetch is a technology that helps Windows to manage the amount of RAM (Random Access Memory) in the machine it runs on more efficiently. SuperFetch was introduced first in Windows Vista and still holds an important part in Windows 7s physical memory management. A less capable version, called PreFetcher, is included in Windows XP. SuperFetch tries to make sure often-accessed data can be read from the fast RAM instead of the slow hard drive. SuperFetch has two goals. The first is, it will decrease boot time as in SuperFetch will record which data and files need to be accessed at which times, and stores this data in a trace file. During consecutive boots, this information is used to make the loading of files become more efficient, resulting in shorter boot times. The Second goal is SuperFetch will make sure the applications that you use the most will be loaded more efficiently. SuperFetch will also adapt itself to your usage patterns and put it into account. SuperFetch does this by pre-loading your most often used applications in your main memory, based on not only usage patterns, but also on when  you use them. For example, if a user has the same routine every morning, he will run the Mozilla Firefox and browse the Facebook, SuperFetch will pre-load these into memory in the morning. And then comes the evening, the routine will be different, like he will run iTunes and plays his playlist, SuperFetch will adapt, and load those in memory instead during the evening. Analysis Microsoft SuperFetch can give memory manager a hand to divide an often used program into priorities. So it will become more responsive and of course save some time. Despite on its advantages, SuperFetch has some limitations. The limitation is that SuperFetch will spend the leftover free memory on a low-priority applications and processes. The effect will occur when the user tries to run a high resolution video or high performance game, the effects will slow down the computer because there are no more or very few free memories left. Solution Microsoft SuperFetch need to have some reserved memory for some applications that require a lot of memory in their processes. SuperFetch should allocate the free memory for the high performance processes also, without neglecting the existence of low priority processes in the free memory. It does not have to be balance exactly, but an equal allocation for processes is a must. Virtual Memory Management Virtual Memory Management is a memory management technique that is made of various hardware memory devices such as RAM modules and disk storage drives. Virtual memory is used to help physical memory to execute more processes because some pieces of processes are loaded to physical memory and other pieces will be loaded into virtual memory, so physical memory can handle more processes and will be in ready state at any particular time and also virtual memory can handle a process that may be larger than physical memory by loading some required pieces and then the rest pieces of processes will be loaded onto virtual memory. Demand paging Demand paging is one of the virtual memory management technique that load some part of the processes into virtual memory instead of load all part of the processes into physical and virtual memory and later the part of the process from virtual memory will be brought it into physical memory when its need the rest of parts of process. Operating System such as Windows is using demand paging as its virtual management technique but there are some problems in managing virtual memory in the demand paging at Windows XP and previous versions had and the solutions has been provided by Windows 7. Kernel address space Windows Kernel virtual address space is allocated into 2 sections, which are User address space and Kernel address space. Important resources in Kernel address space are adjusted according to the operational requirements. The sizes and locations of the resources are included as a management of virtual memory arranged by the operating system. Analysis In Windows XP and its previous versions, Kernel address space had been allocated statically into some fixed sizes and locations, so it will have some major problems in case that one or more of the resources oversized than its size allocation. The processes will not work well as usual in result. In Windows Vista and 7, the problems have been overcome by expanding the size and provide the size and location for the resources together. Nowadays, in Windows 7, Kernel address space shares the same space and is no longer divided into some sections. But it still have some limitations, the space is not dynamic enough to handle a very oversized resource. The same result of previous version of Windows still might be occurred. Solution Kernel virtual address space should be dynamic enough to overcome any possibilities. The user address space is a space that will not be unavailable each time, so it does not mean it cannot be available to handle some oversized-resources problem. The virtual memory space should be dynamic enough to let user address space to share a little space for the Kernel address space. Conclusion Windows 7 uses same techniques in memory management with previous versions of Windows which are System Paging in physical memory management and Demand Paging in virtual memory management. Microsoft develops a technology to help physical memory manager to work more efficient, which is called Microsoft SuperFetch. For the virtual memory manager itself, the allocations of the Kernel address space has been better since the introduction of Windows Vista and better in Windows 7 though it still has some limitations. FAQ What is Windows 7? Answer: is the latest release of Microsoft Windows for use as an operating system on personal computers, including home and business desktops, laptops, netbooks, and tablet PCs. What is the benefit of Microsoft SuperFetch? Answer: Microsoft SuperFetch can give memory manager a hand to divide an often used program into priorities. So it will become more responsive and of course save some time. How exactly the virtual memory works? Answer: Virtual memory is used to help physical memory to execute more processes because some pieces of processes are loaded to physical memory and it can handle a process that may be larger than physical memory by loading some required pieces and then the rest pieces of processes will be loaded onto virtual memory. Section 2 (Two) : Microprocessors Introduction Microprocessor is the main brain of a computer. Microprocessor is also known as the Central Processing Unit (CPU) that has main function to respond to and to generate arithmetical and logical operations.   The microprocessor is the heart of any normal computer, whether it is a  desktop machine, a laptop, or a server. Microprocessor is a complete computation engine that is fabricated on a single chip. The first microprocessor was the Intel 4004 which is introduced in 1971. The 4004 was not very powerful. But at that time it was quite an invention since everything was on one chip. Even though the 4004 powered one of the first portable electronic calculators, all it could do was to add and subtract. Nowadays, there have been a lot of improvements in modern microprocessors. This report will cover some areas such as major trends affecting microprocessor performance and design in recent years and differences between microprocessors design goals for laptops, servers, desktops and embedded systems. Microprocessor Performance Since microprocessor has an important main role in the entire computers work and performance, then it is also important to concern about the performance of the processor itself. As time goes by, performances of microprocessor have always been improved to be better in architecture, faster in speed, smaller in size, and lower in energy consumption. Microprocessor at this time is built and developed to meet those requirements. In purpose to meet those requirements, there are some measurements and factors that affect microprocessor performance. Some of the major trends affecting the microprocessors performance are: Clock speed Microprocessors job is to process tasks/instructions and executes them. How fast a microprocessor can do its job to complete a cycle of task from when its retrieved from its  memory, determines what actions the instruction requires, and carries out those actions matters because it measures the performance of the microprocessor itself. The clock speed is stated in megahertz (MHz) or gigahertz (GHz), and is a measure of how many instructions the processor can execute in one second. For example, a three Gigahertz (GHz) processor can operate at a rate of three billion cycles per second. The more cycles a processor can handle per second, the faster the clock can pump the current and the better the performance of the microprocessor. Number of Cores Number of cores will first determine whether it is a single-core microprocessor or multi-cores microprocessor. Multi-cores microprocessor is designed to have more than one core integrated to a single chip. Multi-cores microprocessor allows a complex instruction to be divided into some simple instructions to each of its cores, so that the instructions can be executed faster. Microprocessors such as Intel core i7 and AMD Phenom II X4 are examples of modern multi-core microprocessors. Instruction Set Architecture (ISA) Instruction set tells how to execute duties and works in the processor. Together with processor architecture will affect performance so it means the better instruction set and processor architecture the better performance of processor will get. Instruction Per Clock (IPC) IPC is the average number of  instructions executed for each clock cycle. IPC massively depends on the architectural design of the microprocessor and its number of transistors. A microprocessor with high clock speed is meaningless without IPC. It is pointless to have a fast-speed microprocessor if it can only execute four or five instructions. On-Board Cache Processors have resources to get their data from, which is the computers Random Access Memory (RAM). After the data is retrieved by the processor, it will copy and send it to a cache. The cache acts as a temporary information way station. Nowadays, the architecture of a microprocessor provides an on-board cache which is internal RAM that is built directly into the processor. Rather than requesting data from the RAM continuously, the CPU is allowed to access used data directly from its own on-board memory instead. This way, CPU can access and process data faster and more accurate. Its very effective for the applications that need high performance such as games, video player, etc. Type of Microprocessors for Desktop, Laptop, and Server Desktop Intel Core i5 (2nd Generation) Intel Core i5 (2nd Generation) is included in the family of Intel Core Processors. It is a newly-developed processor after being preceded by the first generation. Intel Core i5 (2nd Generation) was launched first at January 9th 2011 together with Intel Core i7 (2nd Generation) and are based on Sandy Bridge microarchitecture, unlike the first generation. This microprocessor has features such as, Intel Turbo Boost Technology 2.0, a later version which is better at accelerating performance than the first generations version 1.0; Intel HD Graphics 3000 that integrates high-performance graphics and media processing on the processor, putting the two components which is CPU processing and graphics on a single chip. Laptop Inter Core i5 Mobile (2nd Generation) Intel Core i5 Mobile (2nd Generation) does not have much differences from Intel Core i5 (2nd Generation) except it is designed for laptops so that there will be a difference in its design and architecture that will adapt with the power consumption and energy efficiency. This microprocessor also has the same features like the desktop version, for example Intel Turbo Boost Technology 2.0 and Intel HD Graphics 3000. Server Intel Xeon E7 Intel Xeon E7 is multi-core microprocessor that is targeted for non-customer, server and workstation markets. It has 10 cores processing that enables improved virtualization performance and increasing system utilization. This microprocessor is also based on the newly-developed Sandy Bridge microarchitecture which is up to 17% faster clock-for-clock compared to Nehalem microarchitecture processors of the previous generation. Differences between Microprocessor Design for Desktops, Laptops, Servers, and Embedded Systems Desktops Desktop computers can be said as normal media in computer usage. Desktops have advantages in their access to AC electricity as power source. So, theyre become beneficial to users who want to utilize the best performance of computer. That is why desktops microprocessors do not have to limit their clock speed and referring to the spaces that desktops have for cooling fans, heat problem will not become an issue. Desktops microprocessors are designed to improve the computers performance. So, they will consume more energy than laptops. But the size of them is still smaller than microprocessors that are designed for servers. Laptops Laptops are designed to be used on the go. The criteria are to be flexible so it can be brought anywhere, anytime. So, battery power is the main source of a laptops life. Other than that, overheating is also a main issue since laptops size that does not provide a large space for cooling fans. These criteria and issues become a consideration of why there must be a differentiation in laptops microprocessors. Laptops microprocessors are designed to minimize the power consumption, so that the battery life could last as long as possible. In purpose to overcome the heat problem, laptops processors usually have lower clock speed than the desktop version. As the clock speed is lower, the laptops processors may have a lower bus speed as well. Most of the modern mobile microprocessors have some components to the chips, such as wireless networking cards. Desktop microprocessors could have these as well, but the space requirements of a laptop make these integrated chips way much more popular in laptops. Servers Servers must be available and stable every time. Servers have an important role to store and load important data so everyone in the company can access the server every time. Server microprocessors are designed to overcome issues such as, stability, server uptime, and energy consumption. Servers are usually high-end computer since there are a lot of heavy tasks that needed to be completed. The size of the microprocessors is usually a bit larger than desktops and laptops, regarding to handle the tasks and the electricity consumption. That is also a cause of why server microprocessors will become more sensitive to the heat issue. Overheated- microprocessor will decrease servers performance, so there is another method to take care this issue, like putting the server computers in a room with air conditioners in it to maintain the heat issue. Embedded Systems Embedded systems are predefined systems that specifically can do one or more functions but they are limited based on the purposes. Embedded system cannot be changed by the end user because in case if that is changed, then the embedded system will not run appropriately. Examples of the embedded systems are such as, handphone, calculator, etc. Embedded system will need the microprocessor based on the functionality that it held, the more functions it held, a more powerful the processor that it will need. This happens because the microprocessor will run a lot of instructions from the user, and it will need a capable microprocessor which can do a lot of processes in a short time. The less function it held, there will be reasons to have such a standard microprocessor to save more energy and production cost. Conclusion Microprocessor has an important role as the main brain and operates the processes in computer. Without a microprocessor, a computer cannot do anything. That is why the performance of the microprocessor itself becomes the main priority for the user. There are some major trends affecting the microprocessor performance, which are clock speed, number of cores, instruction set architecture, instruction per clock, and on board cache. Though its main function is the same, computers type varies because of their purposes. So the type of microprocessors will vary also based on their purposes. Type of microprocessors will have a slight difference between one and another because of the design. There are each design for laptops, desktops, servers, and embedded systems.

Broadcasting in the UK Essay -- Television TV Antenna Digital Essays P

Broadcasting in the UK Introduction: Broadcasting, the transmission of information by radio or television, is a major factor affecting the television industry today. Broadcasting is currently achieved through analogue, a system that has existed since television began in the 1940’s and 50’s. "Analogue converts sound and pictures into waves, which are then transmitted through the air and picked up by our rooftops or indoor aerials." But, because of rapid technological advances in the modern era, analogue will soon be obsolete, and is presently in the process of being replaced by digital broadcasting, the new form of broadcasting that "turns pictures and sound into computer language, which changes one’s television into a form of computer, so that it can connect to the Internet, take interactive programs, and carry many more channels," all of which cannot be accomplished through analogue. As modern technology grows, the television industry is introduced to major issues, such as low consumer confidence, analogue switch-off difficulties, and the lack of technical skills. And unless these problems are resolved soon, they will lead to the collapse of the television industry. Lack of skills: Concerns associated with employee technical skills is becoming very common in the digital TV industry. The industry fears that its employees may lack the advanced technical knowledge required for the future. Its major concern right now is to find the right people with the right skills to effectively implement future strategies. Digital TV companies must become much more competent, innovative and creative, which means that its employees must be willing to develop themselves and their company in order to sustain the industry. As many are aware, IT skills will be very essential to the well-being of the industry. Because a number of shoppers today are already purchasing products online – and Internet access via digital TV exists, advanced IT skills are definitely required for the future health of the digital TV industry. However, since the demand for specialist IT skills is increasing and the human resources are limited, there exists a shortfall – one that appears to worsen . It has been reported by e-commerce consultancy, Spectrum Strategy, that over 850,000 e-business jobs could be created in Britain by 2003. But unfortunately, due to skills shortages, the digital TV indu... ...emove public confusion. However, ONDigital and SkyDigital have also pursued a common plan. Both companies have negotiated a plan with the UK Parliament to aid their shared issue. But unfortunately for both, Parliament has not yet conducted any of its promised public info campaigns. Conclusion: In conclusion, the future of digital television is unpredictable. Who knows where our high-tech society will end up next? Because technological advances are happening "right before our eyes," the TV industry is forced to "keep up with" modern technology. If this cannot be accomplished effectively, the industry will experience its gradual downfall. The UK government must help the industry "stay on track" and ensure that its products are agreeable to public interest. But in order to do so, Parliament must take a serious stand on the issue and motivate itself to promote public awareness of the benefits of converting to digital TV. If Parliament fails to play an "active" role, results for the television industry will be extremely negative. Not only will this give the industry a "bad" reputation, but it will also cause the Parliament itself to have a long-term negativereputation as well.

A Trip to the Grocery Store

As far back as I can remember, one of the activities that my mother and I enjoyed doing a lot together was going to the grocery on a weekly basis to stock up on our food and household supplies.I remember that my mother had certain brands in particular that she preferred over others. I really did not pay so much attention as to why she chose certain brands. All I knew back then was that the stuff she got turned into food for me to enjoy eating. That was the part of my childhood when I could roam about the grocery store, take one bag of potato chips, or a can of soda to enjoy during the drive home.But as I got older, my mother began to teach me how to buy things at the grocery store. She told me that â€Å"You need to learn how to buy these things because you are old enough to go to the grocery store for me already if I need you to.†To which I often replied, â€Å"But Mom! Only the names change. Bath soaps are all the same!† Then she would try to convince me that eventual ly I would setting up my own home and I would need to be making these decisions for myself so I needed to learn the rudiments now.While she could still guide and advise me about it. Needless to say, no amount of explanations from my mother could convince me that I needed to be a discriminating buyer. At that age, I did not feel any need to learn about comparing products, getting the best buy, and spending within a food budget. Our cycle was really simple, I went with mom to the grocery store, I got the foodstuff that I liked or looked good and she took care of the rest.As I began my high school education, mom started to give me a bit more responsibility when it came to purchasing items at the grocery store. She always kept it simple for me because she knew how I would just grab the first item on the shelf that related to the item she had listed down.So mom always listed down the item and the specific brand name she wanted me to get. Each time she handed me the list she would tell me â€Å"Do me a favor and read the label of the other brands available. There might be a better product out there.†Being a teenager at the time, all I had in mind was to get the errand done and go on with whatever other activities I had in mind for myself. So I never really bothered to read about the other similar items in those aisles. Little did I realize that the time would come when I would need to know about all those items in the aisles and how they compared to each other in price, quantity, and quality. I kind of took it for granted that whatever mom had listed down was the one I should purchase.Then came time for me to spread my wings and move out of the house into an apartment of my own and keeping house for myself for the very first time. I would have to keep to a budget and decide upon grocery purchases by myself and for myself. Since I had no previous experience with going to a grocery store and buying my own stuff, I suddenly felt overwhelmed and scared.The grocer y store looked like a huge hangar to me and I was lost in a sea of products that all looked the same to me. But in the back of my mind I could still hear my mom telling me to â€Å"Read the labels and choose the best product for my money.â€Å"I was not confident I could do that without the security of my mom’s grocery list with me that contained a list of all the necessary items and brands. I was worried by tried to convince myself in whispers that   â€Å"I can do this. How hard can it be to buy my food and supplies?†I felt a cold sweat come over me as I wheeled my cart into the main shopping area. 6 different types of   fresh milk each carton looking better and saying something newer than the next. Rows upon rows of vegetables, the limitless canned foods, soap brands, fabric softeners†¦ how could anybody make that choice immediately?I decided that I needed back up and whipped out my cellular phone. I dialed a number and waited for the familiar voice over the answering machine to pick up. â€Å"Mom! Pick up the phone!† I hollered after the beep.â€Å"I need your help!† It seemed like an eternity for my mom to pick up the phone. â€Å"What’s the matter?† her worried voice said. I told her my problem. I was stuck in the grocery store without her list and without a clue as to which items to buy. Could she please tell me what to get? I heard my mom sigh deeply before saying â€Å"You are on your own now. It is time for you to make your own choices in life. You don’t need my list. You just need to find out what things you like.â€Å" I tried to explain to her that I was not sure what things I liked because she always had that list for me to refer to. I really needed it at that moment. â€Å"Trust yourself.† she told me. â€Å"You will know which products you will be using regularly. It just takes a bit of time to develop the skill. Go with your instincts† As we ended the conversation, I w as not sure if I could trust myself to make that choice. After all, I considered pizza with a liter of soda a healthy meal.It took me 4 hours to shop for groceries that day. Without my moms list, I was forced to do what I never had to do before, compare products, learn to choose the best brand, and be comfortable for any mistakes in choices that I may have made.But I realized that as I took the time to read the product labels and ponder upon my choices, I began feeling a sense of freedom and responsibility for myself. That phone call and trip to the grocery store made me realize that if I were to call myself an adult, I would now have to take charge of my life, make my own decisions, and learn to make wise choices. Nobody would be there to decide for me anymore.Guess what? I have slowly evolved from that unsure person terrified of all the product choices out there who tried to get her mother to make a grocery list for her into a wise, budget conscious shopper, and it makes me feel g reat!

Free Essays on The Cast of Anontillado

The Paradox of Revenge â€Å"The Cask of Amontillado† raises a question pertaining to the multiple character of the self (Davidson 202); Can harmony of one's self be restored once primal impulses have been acted upon? This question proposes the fantasy of crime without consequence (Stepp 60). Edgar Allan Poe uses first person point of view, vivid symbolism and situational irony to show that because of man's inner self, revenge is ultimately not possible. Edward Davidson suggests that Montresor, the main character of the story, "has the power of moving downward from his mind or intellectual being and into his brute or physical self and then return again to his intellectual being with his total self being unimpaired" (202). However, Poe tells this story from Montresor’s point of view. The use of first person narration provides the reader with insight into Montresor's inner struggles. First person narration is Poe's method of insuring the reader understands that Montresor is not successful at this harmony. The thoughts and feelings of Montresor lead the reader to conclude that he is not successful at revenge. Montresor says in telling his story, "You, who so well know the nature of my soul, will not suppose, however that I gave utterance to a threat" (153). By communicating in this way, the question arises of who Montresor is actually speaking to, and why he is telling this story fifty years later. One can only conclude that it is for one of two reasons: he is either bragging or finally giving confession. As he tells the story, it becomes obvious that he has not yet filled his need to win, and now a half of a century later, is still struggling with his conscience. As Gregory Jay states, "Introspection produces a doppelganger who becomes a moral antagonist" (84). This is similar to Ken Frieden's theory that a rhetorical moment takes the place of a ghost and the speaker is driven to confess (144). Both of these thoughts are developed becaus...

American Providentialism Through Eras Essays

American Providentialism Through Eras Essays American Providentialism Through Eras Essay American Providentialism Through Eras Essay American Providentialism through Eras Centuries ago John Winthrop preached on board Arbella to the people full of hopes and desires for their new life. He talked about the beautiful Promised Land and the new paradise on earth. Winthrop’s motivational speech â€Å"A Model of Christian Charity† was supposed to encourage people on board Arbella to fulfill their destiny and create a pure society just like God intended them to. The inhabitants of the New World were chosen by God to create a new society which will serve as an example for the rest of the world. John Winthrop insisted on people being united as one body in Christ through brotherly love for one another and through love for God. â€Å"[T]rue Christians are of one body in Christ (1 Cor. 12). Ye are the body of Christ and members of their part. All the parts of this body being thus united are made so contiguous in a special relation as they must needs partake of each others strength and infirmity; joy and sorrow, weal and woe. If one member suffers, all suffer with it, if one be in honor, all rejoice with it. [T]he ligaments of this body which knit together are love. (Winthrop, 4) At the very beginning of existing of America, the main task of its inhabitants was to be united. Religion was their knitting thread. Since they had not yet formed their laws, they lived according to laws of the Church. America’s destiny was to be â€Å"one nation under God† and God was leading them closer to the fulfillment of this destiny. â€Å"[W]hile the law did not abrogate [their] institutions, and the theocracy to be inaugurated did not supercede them, God was all the time educating them to broader views of their destiny †¦ they were to perform as a chosen people among the nations of the earth. (Pierce, 3) God has chosen the people abroad Arbella to create a nation of all nations and He was along their side in all times. During the Civil War the knitting thread between the people was lost because of different views on the issue of slavery. The northern states wanted to abolish slavery while the southern states were against it. Since Americans could fulfill their destiny only if they are united, they saw the Civil War as the wrath of God towards them for being separated. America was separated into the United States, or the Union, and Confederate States of America, or the Confederacy. â€Å"Both parties deprecated war, but one of them would make war rather than let the nation survive, and the other would accept war rather than let it perish, and the war came. † (Lincoln, 1) Lincoln thought that northern states wanted to destroy the Union and that they were ready to fight a war for that cause, while the southern states would do anything to keep the nation united, so they accepted the war to preserve the Union. Lincoln believed that the war was the wrath sent from God because the nation was separated.
