Free Essays on Four Main Parts Of A Computer

The four categories are the processor, memory, input and output devices, and storage devices. I will explain what each one of these are, in definitions. The Central Processing Unit (CPU) is what we call the processor. The computer CPU is responsible for handling all instructions and calculations that it receives from other hardware components in the computer, and software programs running on the computer. There are many different speeds of processors, but I can’t name all of them. Memory is the electronic holding place for instructions and data that your computer's microprocessor can reach quickly. Memory is often referred to as random access memory (RAM). The RAM accesses instructions and data from the more slowly accessed hard disk form of storage. There are four sections of memory, external memory, high memory area, upper memory area and conventional memory. External memory (XMS) is directly accessible memory starting at 1 MB. High memory area (HMA) is the first 64 KB of XMS, the extended memory above the first 1MB of memory. Upper memory area (UMA) is located between 640KB and 1MB. Upper Memory Block (UMB) is areas of upper memory that is remapped into RAM. Conventional memory portion of the RAM is the only portion of memory DOS. I/O (input/output), is any operation, program, or device that transfers data to or from a computer. Typical I/O devices are printers, hard disks, keyboards, and mice. A storage device is capable of storing data. The term usually refers to mass storage devices, such as disk and tape drives. So this explains the four categories of computer hardware, and their component’s and section’s....

CAMPBELL KEYBOARD CORPORATION Essay Example | Topics and Well Written Essays - 750 words

CAMPBELL KEYBOARD CORPORATION - Essay Example As a result of the nature of the order, Ingborg proposed two options for the quotation. The first quotation was to be based on the worth of the entire job which Plum Computer was willing and able to pay Campbell Keyboard. This proposal would therefore be in principal, a fraction of the payment made to Campbell Keyboard. Consequently, Smith had to disclose the value of the job to Ingborg so as to come up with a quotation price for the RF transmitter. In my opinion, this proposal meant that Smith would disclose vital information by revealing the worth of the job. By so doing, Ingborg would have tied the cost of the RF transmitter to the whole value thereby attaining a higher price. Attaching the cost of the RF transmitter to the value of the whole job would not be realistic as the transmitter is being purchased by Campbell Keyboard, thus Ingborg should not be concerned with the contract in place between Campbell Keyboard and Plum Computer. Smith should therefore not agree to this propo sal since it not only reveals information on a contract with a client but it is also an expensive option due to it being a percentage of the entire value of the job. The second proposal from Ingborg was for $33 per hour straight time and $40 for overtime based on the actual hours spent on the job. This proposal is more realistic as the cost is based on the amount of hours that Ingborg put in the production of the RF transmitter. In my opinion, this is the best proposal of the two not only because the cost is based on the work done but also because it would be cheaper than the first proposal in the long run. This option is also better for negotiating on the side of Smith since the cost per hour can be negotiated lower than is stated by Ingborg. Although it would be difficult to ascertain the exact hours worked by Ingborg, Smith has more leverage in this proposal than the previous one. Are there any other choices open to Smith for arriving at an equitable agreement? Smith can research on the market charges by the other firms and use the average as a basis for negotiating. The market prices for the three other sources could be essential to coming to an agreement. Even though the three other companies were not in a position to handle the order due to time constraints, Smith can still get the cost they would charge on making the RF transmitter and use the average during the negotiation with Ingborg. By so doing, Ingborg would realize that Smith has knowledge on the on goings in the market thus giving Smith a bit of leverage during negotiations. Another option available to Smith is giving a counter proposal that is based on the cost of producing the RF transmitter that Campbell Keyboard has incurred in the past. Campbell Keyboard also produces RF transmitters but due to the time limitations in place for this new order, it is difficult to manufacture hence the need to outsource the product. Therefore, in order to come to an equitable agreement, Smith can use the cost of manufacturing the RF transmitter that Campbell Keyboard has incurred in the past and use it as a basis for negotiating with Ingborg. By doing this, a relatively fair price can achieved on the side of Campbell Keyboard and an equitable agreement can be arrived at. How would you have handled the procurement if you were Smith? If I were Smith, I would invite proposals from companies who could make the RF transmitter within the time frame and specifications needed, to bid for

Drugs and their influence Research Paper Example | Topics and Well Written Essays - 2500 words

Drugs and their influence - Research Paper Example In 2004, the famous Whitney Houston disappointed many of her fans when she was arrested because of drug use. She ended losing her voice and reputation. In 2009, Michael Jackson shocked the world with his death that is associated with drugs. Such cases are only a few of the many unknown cases of drug users. Other effect is on the economy of the government. Billions of government money has been spent to treat victims of drug abuse and eliminating its supply but it seems victims of it and its illegal market grew even more. Tom Whitehead (2011) in his editorial report mentioned that the government has wasted 100 billion pounds tackling illicit drug markets. Because of this, aggressive attempts to prevent abuse of drugs by the government not only in the United States but internationally have been enforced. The supply and cost, risk factors of illegal drug use, and practice of physicians all influence the continuous habit of using drugs. Understanding these factors may lead to better strat egies or techniques in dealing with the problem of drug use in the United States. Review of Related Literature Influence of Supply and Costs of Illegal Drugs in its use Most problems of drug use in the Unites States are rooted in the supply. The supply of illegal drugs is abundant in some States of the country especially in the southern part because of its proximity to Columbia and Mexico which are the largest producers and suppliers of heroin, cocaine, and methamphetamine (Reuter, 2009). Drugs flourish in the Northern cities of Mexico and seem too crawl beyond its border and expand to United States through its border cities. This claim is further supported by the study by Bucardo and company (2005) where they explained that Mexican border crossings might be a contributory factor on the rampant heroin use in the border cities of the United States. History also reveals that Mexican and Columbian drugs reach the United States and Canada via the Caribbean. With the proliferation of dru g production in these neighboring countries, eliminating drug use is almost would be difficult. Not only illegal drugs are abused because of abundant supply. Cigarette, alcohol, marijuana, and over the counter (OTC) drugs are also commonly abused. More than 46 million individuals in the United States alone are smokers. The supply of cigarette and alcohol makes it an easy choice of drug abusers to shift from illegal drugs to cigarette and alcohol instead. Today that law enforcers are becoming stricter in the implementation of laws in clamping down drug traffickers, supply of cocaine was reduced forcing drug users to resort to over the counter drugs too. Most often, pain killers like codeine, morphine, and oxycodone are abused as a replacement of illegal drugs. Cost also influences the proliferation of drug users. Low price encourages users to continue the use of illicit drugs because it is affordable. Ironically, policies prohibiting its sale caused the price of the commodity to decr ease and that drug users could easily avail of it. The increased capture of drug traffickers by coast guards and other government authorities had significantly resulted in the low price of the commodity favoring drugs users because of reasonable price. Report also stated that the price of heroine had further deteriorated to 30% more even with a 26% seizure rate of heroine throughout the world (ONDCP, 2004). On the other

Oliver Twist Essay Example for Free

Oliver Twist Essay In Oliver Twist Bill Sykes brings terror to the novel, which adds to the suspense and makes you want to read on. Bill Sykes is brutal which you soon realise when he delights in beating his dog or girlfriend, Nancy. Many novels of this time were full of such characters and Dickens, a playwright and an actor as well as a novelist, knew then well. The orphan Oliver Twist escapes from the workhouse by running away to London. Oliver is introduced to Fagin who trains him to be a thief and he is then taken on a burglary with Sykes, Oliver recovers from being shot in the burglary and Nancy nurses Sykes back to full health. Sykes kills Nancy, which has a terrible effect on him, and he later kills himself. Bill Sykes brings the real terror to the novel but he is also extremely unpredictable. Rarely he can seem quite reasonable and occasionally shows kindness to his dog and girlfriends, but generally he keeps everyone in fear of what he is going to do next. We see evidence of this when Fagin says, You wont be too violent Bill? This statement shows that they have no trust in him. Bill Sykes also has a problem with alcohol, he drinks far too much, and this probably accounts for some of his unpredictable behaviour. We see evidence of his drinking problem when he says, to prevent my standing treat for a pint of so. This shows that he thinks that he thinks drinking is a treat and does not himself think that he has a drinking problem. Bill Sykes us the archetypal Victorian villain. To be a real villain Sykes must show no compassion for anyone and we see that on many occasions. When Nancy has nursed him back to health, staying up for nights looking after him, he turns on her the moment he wakes up. This shows he is very ungrateful for any sympathy given to him. Illness had not improved Mr Sykes temper, for as the girl raised him up and led him to a chair, he struck her . He is also quite ready to send Nancy out to work and possibly profit from what she does. From all of this we can gather further evidence that he is ungrateful for any help he received. Sykes treats his dog very badly, it receives regular kicks and is threatened constantly. At one time when he was going to escape he contemplates killing, The dog, though. If any descriptions of him were out, it would not be forgotten that the dog was missing. Sykes is a typical bully who shows no remorse for what he does to others. We see evidence of this when he takes Oliver on the burglary with him and does not care whether Oliver gets injured. Sykes has no respect for Fagin and you can tell this by the way he speaks to him. You can see Fagin is afraid of him but Fagin does like to have the last word. If Sykes does not get his own way he will turn to violence as we see with the arguments over Oliver, looking sternly at him, and ostentatiously passing a pistol into a more convenient pocket. Thats lucky for one of us. This shows again Sykes is unpredictable and a bully and brings more tension. When Bill Sykes sees Fagin, Fagin changes the tone of his voice at once. Fagin is obviously afraid of the physical strength of Sykes but Sykes is still wary of Fagin.

The Emancipation Proclamation :: essays research papers

The Emancipation Proclamation The emancipation proclamation was issued by Abraham Lincoln on January 1, 1863, during the American Civil War, declaring all "slaves within any State, or designated part of a State... then... in rebellion,... shall be then, thenceforward, and forever free." The states affected were enumerated in the proclamation; specifically exempted were slaves in parts of the South then held by Union armies. Lincoln's issuance of the Emancipation Proclamation marked a radical change in his policy. After out break of the Civil War, the slavery issue was made acute by the flight to Union lines of large numbers of slaves who volunteered to fight for there freedom and that of there fellow slaves. In these circumstances, a strict application of established policy would have required return of fugitive slaves to their masters. Abolitionists had long been urging Lincoln to free all slaves, and public opinion suported that view. Lincoln moved slowly and cautiously nonethe less; on March 13, 1862, the federal government fforbade all Union Army officers to return fugitive slaves, thus annulling in effect the fugitive slave laws. On April 10, on Lincoln's initiative, congress declared the federal government would compenste slave owners who freed their slaves. All slaves in the District of Columbia were freed in this way on April 16, 1862 . On June 19, 1862, Congress enacted a measure prohibiting slavery in United States territories, thus defying the supreme court decision in the Dred Scott case, which ruled that Congress was powerless to regulate slavery in the territories. Finaly, after the union victory in the battle of antietam, Lincoln issued a preliminary proclamation on September 22, declaring his intention of promulgating another proclamathion in 100 days, freeing the slaves in the states deemed in rebellion at that time.

Effectiveness of Airasia’s Performance Measurement System Essay

We could see that this system used by AirAsia is successful as they have been doing really well and improving since year 2001 from first airline in the world to introduce mobile booking, to be a public listed company on the Malaysia Stocks Exchange (Bursa Malaysia), after having on 22 November 2004. In line with its growth and expansion plans, AirAsia has secured a 175 aircraft commitment with Airbus for its A320s. The 175 aircraft order will place AirAsia as the single largest customer for the aircraft in Asia-Pacific, and potentially one of the largest airline fleets in the region. On 23 of March 2006, AirAsia successfully moved its operations to the new Low Cost Carrier Terminal (LCCT). This is a major milestone as it is the first dedicated terminal for low cost carrier operations in the world. Besides that, they have achieved many more heights even in the past 2 year. AirAsia are focus on its performance measurement system and made sure that whatever they do are in line with the system and try as hard to meet its benchmark. For example, to ensure the safety of guest and employees, the â€Å"List of Checks for Airbus A320† is created. These safety procedures include strict aircraft maintenance, constant updating and training of technicians and flight crew. Once any problems occur during this checklist, immediate action will be taken, making sure it is safe and no problems will occur. Because if the safety are threaten, it will influence the investors, potential customers and rest of the stakeholders to loose confidence in AirAsia, making it hard for AirAsia to achieve their vision. With all this achievements, awards and significant milestones in just 6 years, it is obvious to see that the performance measurement system that AirAsia is using is effective and efficient. This system set a very good benchmark to all the key elements in helping AirAsia achieve its vision and goals. By following the system, AirAsia gives priority on areas like cost efficiency, branding, product development, growth, human capital, safety of guest and employee. The performance measurement system applied manage identify prominent areas that will affect its business and lead it towards its goal and vision.

Absolutism in Europe – Summary

During the 17th century two future rulers, Peter the Great of Russia and Louis XIV of France, were born who would push absolutism to new heights. Absolutism is a form of government where all the power is in the hands of one individual. Absolute monarchies are the most common form of absolutism. Peter the Great and Louis XIV had similar traumatic experiences involving people with traditional power during their childhoods. Louis’ was the Fronde, a rebellion by nobles. The Fronde began in 1650 when Louis was a young boy.Many times during the uprising his life was put in danger as his mother and himself were occasionally treated as prisoners. They also had to retreat from Paris. Peter the Great’s traumatic childhood experience was the Streltsy uprising of 1682. The Streltsy, the traditional guards of the nobles in Russia, mobbed the Kremlin after rumors were circulated that Peter’s half brother, Ivan, had been killed. They lynched many nobles including two of Peterâ €™s uncles. The killings were quite brutal, including some being thrown off of balconies unto the Streltsy’s bayonets.The young Peter witnessed this and it began his deep mistrust and hatred of traditional ways in Russia. Another similarity of Peter and Louis was their handling of their nobles. They both took power from them in different ways. Louis built the luxurious palace of Versailles. The grand building project of Versailles employed many artisans and common builder for a lifetime. Thus it was supported by the population of France. Many of the most prominent nobles were forced to live there for about half a year in apartments. Their actual power was essentially traded for social pomp and court life.They filled their days with various social acts like watching the rising of the King in the morning and the pursuits of the frivolous fashions of the day. Another purpose of Versailles was to show the sheer might of Louis XIV. Peter the Great pushed very hard for moderniz ation of Russia. His need to imitate the west led him to have his own massive building project, St. Petersburg. Conscripted laborers primarily built this new city. The conditions were harsh and over 60,000 died. This contrasted sharply with Louis XIV’s building of Versailles.Another push way forced modern ways upon his constituents was to have dress codes for the royals. He had them dress in western clothing. This was disliked by many, especially the women, for their impracticality for the harsh landscapes of Russia. He also had the men shaved their beards. If they refused he’d cut them off himself. War campaigns Louis XIV and Peter the Great contrasted drastically. Peter was the first ruler of Russia to turn its army from amateur to professional. He abandoned the Streltsy that he had formed a hate from in childhood and began to train his soldiers using modern techniques.His love of the military started in childhood when he would play war with real men. Western general s were brought in to teach the young Peter different formation which they would practice often. Eventually this play army became the beginnings of his real army. In addition to an army he created a navy. Most of Peter’s wars had a purpose and were led by the king directly from the battlefield. His first war against the Tartars, who were backed by the Ottomans, and mostly in the southeast area of the empire.This war was used to secure the border which often fell victim to horrific raids by the Tartars. His second major war was against Sweden. While the Great Northern War was long, 21 years, it gave Peter the land he needed for the port city of St. Petersburg. Also, it marked the last time Sweden was ever a military power. To Louis XIV war was usually just a way to show the glory of France, thus the glory of its ruler Louis. Some of the wars included, the war of devolution, the war against Holland, the war of the league of Augsburg, and the war of Spanish Succession.Most of the se wars resulted in little actual benefits for the victor. That is because they had been mostly for glory. One last notable similarity is how both Louis XIV and Peter the Great dismissed their main advisors at a young age. Louis dismissed his advisors at the age of 23 when he began to truly become the absolute rule her was. Peter the Great did the same at the younger age of 17. Overall Peter and Louis both had major affects on the entire continent of Europe from their reigns onwards. They are both the best examples of absolutism that the world will probably see.

Childrens Health essays

Childrens Health essays Exercise and proper nutrition are the key to having a health child. Nutrition and exercise are important because it keeps people's bodies - and minds healthy. Without both of these factors, we wouldn't be feeling or looking very good. Actually, there are so many reasons why exercise and good nutrition are good for people at every age, and it's a good time to teach children to develop healthy habits and see why it's cool to be fit! Exercise makes your heart happy and your heart is one hardworking part, pumping blood every day of your life. The heart is a muscle, and it's the strongest muscle in your body - but it's always looking to become even stronger! Since it can't lift weights to get stronger, it relies on you to do aerobic exercise. Aerobic is a fancy word for needing oxygen, and aerobic exercise is any kind of activity that makes your muscles use oxygen. Aerobic exercise is repetitive; meaning it's an activity you do over and over, to keep bringing fresh oxygen to all of your muscles. When you do aerobic exercise and bring in that oxygen, your heart becomes stronger and even a tiny bit bigger. The number of blood cells in your blood increases, so the blood can carry even more oxygen. The blood in your body even moves more easily through the blood vessels. All these things mean that your body works more efficiently to keep you healthy and you can do lots of exercise without getting worn out. It' s a good idea for kids to do some kind of aerobic exercise two or three times a week, for 20 to 30 minutes at a time. It's not hard to do - some excellent aerobic activities are swimming, basketball, ice or roller hockey, jogging (or walking quickly), inline skating, soccer, cross-country skiing, biking, and rowing. Even dancing, skipping, jumping rope, and playing hopscotch are aerobic activities. Exercise makes muscles and all the muscles in your body do a fine job when you use them for easy stuff, like picking up...

Interesting and Strange Astronomy Facts

Interesting and Strange Astronomy Facts Even though people have studied the heavens for thousands of years, we still know relatively little about the  universe. While astronomers continue to explore, they learn more about the stars, planets, and galaxies in some detail and yet some phenomena remain puzzling. Whether or not scientists will be able to solve the mysteries of the universe is a mystery itself, but the fascinating study of space and all its many anomalies will continue to inspire new ideas and give impetus to new discoveries as long as humans continue to look up at the skies and wonder, Whats out there? Dark Matter in the Universe   Astronomers are always on the hunt for dark matter, a mysterious form of matter that cant be detected by normal means- hence its name. All of the universal matter that can be detected by current methods comprises only about 5 percent of the total matter in the universe. Dark matter makes up the rest, along with something known as dark energy. When people look at the night sky, no matter how many stars they see (and galaxies, if theyre using a telescope), theyre only witnessing a tiny fraction of whats actually out there. While astronomers sometimes use the term vacuum of space, the space that light travels through isnt completely empty. There are actually a few atoms of matter in each cubic meter of space. The space between galaxies, which was once thought to be quite empty, is often filled with molecules of gas and dust. Dense Objects in the Cosmos People also used to think that black holes were the answer to the dark matter conundrum. (That is, it was believed that the unaccounted for matter might be in black holes.) While the idea turns out not to be true, black holes  continue to fascinate astronomers, with good reason. Black holes are so  dense and have such intense gravity, that nothing- not even light- can escape them.  For example, should an intergalactic ship somehow get too close to a black hole and be sucked in by its gravitational pull face first,  the force on the front of the ship would be so much stronger than the force at the back, that the ship and the people inside would get stretched out- or elasticized like taffy- by the intensity of the gravitational pull. The result? No one gets out alive. Did you know that black holes can and do collide? When this phenomenon occurs between supermassive black holes,  gravitational waves  are released. Though the existence of these waves was speculated to  exist, they werent actually detected until 2015. Since then, astronomers have detected gravitational waves from several titanic black hole collisions.   Neutron  stars- the leftovers of the deaths of massive stars in supernova explosions- arent the same thing as black holes, but they also collide with one another. These stars are so dense that a glass full of neutron star material would have more mass than the Moon. As gargantuan as they are, neutron stars are among the fastest spinning objects in the universe. Astronomers studying them have clocked them at spin rates of up to 500 times per second. Whats a Star and What Isnt? Humans have a funny propensity to call any bright object in the sky a star- even when its not. A star is a sphere of superheated gas that gives off light and heat, and usually has some sort of fusion going on inside it. This means that shooting stars arent really stars. (More often than not, theyre just tiny dust particles falling through our atmosphere that vaporize due to the heat of friction with the atmospheric gases.) What else is not a star? A planet is not a star. Thats because- for starters- unlike stars, planets dont fuse atoms in their interiors and theyre much smaller than your average star, and while comets may be bright in appearance, theyre not stars, either. As comets travel around the Sun, they leave behind dust trails. When Earth passes through  a cometary  orbit and encounters those trails,  we see an increase in meteors (also not stars) as the particles move through our atmosphere and are burned up. Our Solar System Our own star, the Sun, is a force to be reckoned with. Deep inside the Suns core, hydrogen is fused to create helium. During that process, the core releases the equivalent of 100 billion nuclear bombs  every second. All that energy works its way out through the Suns various layers, taking thousands of years to make the trip. The Suns energy, emitted as heat and light, powers the solar system. Other stars go through this same process during their lives, which makes stars the powerhouses of the cosmos.   The Sun may be the star of our show but the solar system in which we live is full of weird and wonderful features as well.  For instance, even though Mercury is the closest planet to the Sun, temperatures can drop to a frigid -280 ° F on the planets surface. How? Since Mercury has almost no atmosphere, theres nothing to trap heat near the surface. As a result, the dark side of the planet- the one facing away from the Sun- gets extremely cold. While its farther away from the Sun, Venus is considerably hotter than Mercury due to the thickness of Venus’ atmosphere, which traps heat near the surface of the planet. Venus also spins very slowly on its axis. One day on Venus is equivalent to 243 Earth days, however, Venuss year is only 224.7 days. Odder still, Venus spins  backward  on its axis as compared to the other planets in the solar system. Galaxies, Interstellar Space, and Light The universe is more than 13.7 billion years old and it is home to billions of galaxies. No one is quite sure exactly how many galaxies there are all told, but some of the facts we do know are pretty impressive. How do we know what we know about galaxies? Astronomers study the light objects emit for clues as to their origins, evolution, and age. Light from distant stars and galaxies takes so long to reach Earth that were actually seeing these objects as they appeared in the past. When we look up at the night sky, were in effect, looking back in time. The farther away something is, the farther back in time it appears. For instance, the Suns light takes almost 8.5 minutes to travel to Earth, so we see the Sun as it appeared 8.5 minutes ago. The nearest star to us, Proxima Centauri, is 4.2 light-years away, so it appears to our eyes as it was 4.2 years ago. The nearest galaxy is 2.5 million light-years away and looks the way it did when our Australopithecus hominid ancestors walked the planet. Over the course of time, some older galaxies have been cannibalized by younger ones. For example, the Whirlpool galaxy (also known as Messier 51 or M51)- a two-armed spiral that lies between 25 million and 37 million light-years away from the  Milky Way that can be observed with an amateur telescope- appears to have been through one galaxy merger/cannibalization in its past.   The universe is brimming with galaxies, and the most distant ones are moving away from us at more than 90 percent of the speed of light. One of the strangest ideas of all- and one thats likely to come true- is the expanding universe theory, which hypothesizes that the universe will continue to expand and as it does, galaxies will grow farther apart until their star-forming regions eventually run out. Billions of years from now, the universe will be made up of old, red galaxies (those at the end of their evolution), so far apart that their stars will be almost impossible to detect.
