The Main Memory System for a Computer Essay Example

The Main Memory System for a Computer Essay Memory is an important component of any computer. A part of the Central Processing Unit (CPU) of a computer, memory performs either of short-term or long-term storage functions. At a conceptual level, memory can either refer to the storage devices themselves (hard-drives, DVDs, etc) or to the data/information stored therein. The Random Access Memory (RAM) is the most important for the functioning of a computer, for it is essential for immediate and high-speed computing operations. But RAM has a limitation in terms of its capacity but the access time is very impressive. In contrast, secondary memory devices offer vast storage capacities for information with the trade-off being slow access time. Computer memory devices are mostly made of semiconductor circuits such as Integrated Circuits (ICs). The basic storage unit for semiconductor memory is called a cell which can store a unit of binary information (0 or 1). Cells are in turn part of memory words of lengths such as 1,2,4,8 so on. These words are characterized by two parameters – 1. their physical address within the device and 2. the data that they contain. The main memory of a computer can either be a volatile or non-volatile memory device. RAM is always a volatile memory and so is CPU cache. Whereas more static and long-term data are normally stored in non-volatile memory. Read Only Memory (ROM) and flash memory are good examples of non-volatile memory. Other examples include hard-disks, blu-ray optical discs, etc. We will write a custom essay sample on The Main Memory System for a Computer specifically for you for only $16.38 $13.9/page Order now We will write a custom essay sample on The Main Memory System for a Computer specifically for you FOR ONLY $16.38 $13.9/page Hire Writer We will write a custom essay sample on The Main Memory System for a Computer specifically for you FOR ONLY $16.38 $13.9/page Hire Writer In order for a computer to function properly, the efficiency with which memory is managed is the key. The Operating System that is installed in the computer has sophisticated systems and procedures at place in dealing with memory. Each operating system (Windows, Linux, Mac, etc) works in its own fashion and has its share of pros and cons. If an Operating System (OS) is inefficient in managing memory it can lead to bugs, which can slow down the overall processing time of tasks. They can also lead to frequent overloads and crashes of user sessions. An inefficient memory management system will make the computer susceptible to malware and viruses as well. With respect to the Operating System’s handling of computer memory, Virtual Memory is part of the set-up. Various applications demand from the OS different memory requirements. The OS creates a virtual memory that dissociates the physical storage location of data from its conceptual processing. The ability of virtual memory to work across storage devices lends it flexibility and adaptability. As technology advances, the speed and capacity of memory devices also grow incrementally. Hence, these days even Personal Computers are enabled to handle complex and simultaneous processing requirements. Far from the primitive text-only basis of computer operations, modern computers play High Definition videos, high-integrity music and are also enabled to play multi-media streams through web-browsers. These impressive features are in large part enabled by vast memory capacity that functions at a rapid pace. But it should be kept in mind that memory in exclusion is of little value. What determines the real utility of memory is the ability of the Operating System and interfacing hardware to efficiently and optimally tap into its capacity. Reference: Arora, Ashok (2006).

Some of the major job attitudes are: * JOB SATISFACTION * JOB INVOLVEMENT * ORGANIZATIONAL COMMITMENT PERCEIVED ORGANIZATIONAL SUPPORT * EMPLOYEE ENGAGEMENT PERSONALITY: IT CAN BE DESCRIBED AS SUM TOTAL WAYS IN WHICH AN INDIVIDUAL REACTS AND INTERACTS WITH OTHERS. Personality can be of two major types : type-A, type-B. The big five factors to describe personality are: * EXTROVERSION * AGREEABLENESS * CONSCIENTIOUSNESS * EMOTIONAL STABILITY * OPENNESS TO EXPERIENCE SOME OF THE PERSONALITY TRAITS ARE: MOTIVATION: IT CAN BE DESC RIBED AS THE PROCESSES THAT ACCOUNTS FOR AN INDIVIDUAL’S INTENSITY, DIRECTION AND PERSISTENCE OF EFFORT TOWARDS ATTAINING A GOAL. Need theories, Goal setting theory, Reinforcement theory, Equity theory and Expectancy theory are some of the motivation theories. ANALYSIS: Examples for the following concepts: 1] ATTITUDE – Incidence is about our neighbour Mrs Kumar, she was looking for a new position as an administrative assistant in her company HCL, she was initially reluctant to learn a new computer program as she could not relate her much with latest technology, but knew that would improve her skills and therefore help her get a better job with better pay. One day she decided to reverse that viewpoint and decided to learn a spreadsheet software program; one that she rarely used in any previous job position. That knowledge could possibly be one of a number of software programs that could aid her in a potential admin position. Within a few hours after learning the program, her boss asked her if she would take up the challenge of the new post vacated in her company sometime back, she agreed and got a new job. Not only that, but the job position involved made extensive use of the very spreadsheet program she had learned sometime before. The effort by Mrs Kumar to learn made her overcome her reluctance and embrace a possibility and opportunity helped trigger an event that led to immediate, startling, and positive life response in that precise domain where she made the change. It seems impossible, but that is precisely how life works. She happily narrated this incident to our family last month. It shows how positive attitude makes all the difference. Few steps that the management could have taken to change attitude of Mrs Kumar are: * Active Participation-Senior manager if would have encouraged Mrs kumar to actively discuss her ideas, suggestions and views about important issues related to organization, she would have been motivated to do better with more involvement. Working together gives a sort of assurance that work is valued by everyone. * Enhanced Communication- The importance of communication is understood only when we actually see the results effective communication brings with it. We need to communicate with the employees from time to time, hold meetings, discuss issues and deal with grievances to eradicate communication barriers. After this, we will understand exactly how to motivate the employees. * Appreciation Rewards -It is very important for the employer to get appreciated, if not reward, work that is properly, or at times exceptionally, done. 2] PERSONALITY: Mr Aman had joined the company Reliance India Ltd 2 months back. He was a young, talented and ambitious manager, handling sales in entire region. He was very determined to complete his sales target. Within a year. He got 3 promotions in the company. All accepted that he used aggressive tactics to climb up the ladder of success. His colleagues and subordinates started calling him insensitive and manipulative. He started having conflicts with managers of the other departments. His performance review showed him to be average in spite of him being dedicated, hardworking and productive. Finaly; he decided to quit the company. He thought of taking advice of his colleague who was also his close friend. His colleague explained him, that he is having all the conflicts because his personality is becoming negative due to very high obsession for success. Aman realized after the entire conversation that he was showing the typical traits of MACHIAVELLIANISM personality. Machiavellianian is person who has tendency to deceive and manipulate others for personal gain. The concept is named after Renaissance diplomat and writer Niccolo Machiavelli. Machiavellianism is the degree to which an individual is pragmatic, maintains emotional distance and believes that ends justify means. High Machs tend to take a more detached, calculating approach in their interaction with other people. In terms of Big Five personality traits, Machiavellians tend to be low on agreeableness and high in conscientiousness. Low Machs tend to take a more personal, empathic approach in their interaction with other people. They tend to be more trusting of others and more honest. They believe humans are essentially good natured. At the extreme, low Machs tend to be passive, submissive, highly agreeable, dependent and socially inept; in contrast with those who are more Machiavellian, they also tend to believe that everyone has a good and bad side. For Mr Aman following steps could have been taken: * Allotment of work according to personality type, best suitable for him. In case of Aman job profile requiring aggressive sales dealing would be most suitable. Motivation by the management about handling conflicting situations by such personality workers. * Conducting employees psychometric and personality tests in the organizations and providing them proper counselling and guidance. 3] MOTIVATION: Mr Talwar who had been working for company Accenture as a consultant for last 2 years was earning a handsome salary o f 2 Lks per month. He is considered to be hardworking and productive employee . However, his colleagues always find him to be dissatisfied and irritated. His juniors always complain about his short tempered nature and over aggressiveness in his speech. After 3 months new Vice Chancellor joins the organization. After going through the performance review and scores of Mr Talwar he decided to meet him and tried to find reasons for his job dissatisfaction. The reason was huge financial loans on Mr Talwar which was making him dissatisfied with his current salary. After discussing the matter with other board of directors and reviewing the annual work performance of Mr Talwar, senior management decided to give him salary appraisal. This motivated Mr Talwar to perform better and gave him job satisfaction. Ways which could have been used to motivate the employee’s productivity: * Guide employees about Organization Culture This is one of the classical motivational methods for employees of a company where organizational behaviour practices have been launched. The business owner and the employees are enforced to think at factors like how the practices would improve the standing of the company in the industry, how the practices will enable to company to boost sales etc. Employee’s suggestions should be taken by senior management. This will not only motivate them to work better but would also increase employee’s loyalty towards company. Provide incentives and manage performanceEmployees should understand that the end of the day what counts for a company is how an employee has performed on productivity and quality. At the same time, discipline and ethics are some things which the company cannot forsake in lieu of productivity and quality. Top management should review the employees work periodically and provide them with additional bonuses and incentives. Also other rewards system could be included. * Reverse Motivation Not many companies have used this technique, but in some cases, this has proved to be a highly effective tool for motivating employees. As per Reverse Motivation, employees are motivated by telling them the consequences of them not implementing the Organizational Behaviour practices. The whole stream of Reverse Motivation works on a completely negative aspect of motivating the employees. CONCLUSION: From the above examples we can see how motivation, personality, attitude affects employees behaviour and functioning in an organization. It is very essential to understand the above factors which determine productivity of employees and achieving goals of the organization.

The Difference Between a Cation and an Anion

The Difference Between a Cation and an Anion Cations and anions are both ions. The difference between a cation and an anion is the net electrical charge of the ion. Ions are atoms or molecules which have gained or lost one or more valence electrons, giving the ion a net positive or negative charge. If the chemical species has more protons than electrons, it carries a net positive charge. If there are more electrons than protons, the species has a negative charge. The number of neutrons determines the isotope of an element  but does not affect the electrical charge. Cation Versus Anion Cations are ions with a net positive charge. Cation Examples: Silver: AgHydronium: H3OAmmonium: NH4 Anions are ions with a net negative charge. Anion Examples: Hydroxide anion: OH-Oxide anion: O2-Sulfate anion: SO42- Because they have opposite electrical charges, cations and anions are attracted to each other. Cations repel other cations and anions repel other anions. Predicting Cations and Anions Sometimes, you can predict whether an atom will form a cation or an anion based on its position on the periodic table. Alkali metals and alkaline earth metals always  form cations. Halogens always form anions. Most other nonmetals typically form anions (e.g. oxygen, nitrogen, sulfur), while most metals form cations (e.g. iron, gold, mercury). Writing Chemical Formulas When writing the formula of a compound, the cation is listed before the anion. For example, in NaCl, the sodium atom acts as the cation, while the chlorine atom acts as the anion. When writing cation or anion symbols, the element symbol(s) is listed first. The charge is written as a superscript following the chemical formula.

Propaganda Essay Example | Topics and Well Written Essays - 750 words

Propaganda - Essay Example Propaganda extends beyond the Machiavellian ‘black’ methods that are often implemented in wartime situations, and includes ‘white’ and ‘grey’ propaganda wherein overtly or subtly stated ideologies are advanced to achieve persuasive means. (Linebarger 1954). One such example of less devious, yet arguably a no less manipulative form of propaganda, is broadcast daily across American television sets – the nightly news. Indeed, recent video leaks of Dan Rather humorously spending five minutes to determine whether to leave his collar up or down for an outside broadcast and Katie Couric mocking then vice-presidential candidate Sarah Palin demonstrates both the high levels of aesthetic and ideological manipulation that go into producing the CBS Evening News (Shea 2008). While there are a diverse amount of tacit ideological assumptions that can be identified in both local and national news broadcasts, this essay examines the specific propaganda me chanisms advanced in the July 22nd, 2010 episode of the CBS Evening News News with Katie Couric. Viewers familiar with the CBS Evening News are aware that the show starts with a nightly overview of what will be included in the broadcasts. This specific episode indicates that the broadcast will include: the BP Oil Spill, the Shirley Sherrod incident, an examination of the immigration debate, and a piece on how researchers used twitter to determine the country’s mood. Already in this programming outline a number of ideological assumptions are readily present. While the news is mythologized as existing in an objective vacuum, where relevant content is reported to the public, it’s clear that the format is much more aligned with the dramatic principles required to draw and hold an audience. In this instance, the CBS Evening News includes the most somber, yet startling information first BP Oil Spill. It seems this ultimately has the effect of catching the viewer up on past o ccurrences; for instance, the daily reports on the minutest details of the BP Oil Spill come to represent a sort of daily drama for viewers, with continuity being made from past broadcasts. The plot twist for the night’s broadcast is that a potential storm may sidetrack the clean-up crews. While the information is presented as direct news, its hidden ideological assumptions are clearly that BP hasn’t done enough in aiding the coast, and now they are further failing as may be unable to accomplish their clean-up before the oncoming storm.

Internal and External Factors of Management Essay Example for Free

Internal and External Factors of Management Essay Introduction Businesses rely heavily on the four basic functions of management Planning, Organizing, Directing, and Controlling; however, the skilled management of internal and external factors will ultimately determine the longevity of the company. Management teams are measured on how quickly they can build a company over a short period. However, the real measure is how well a company can continue to grow. Company success is continually evolving as the world changes, making it difficult on management teams to adapt as internal and external forces mold new paths. Google is a prime example of a leading company who must constantly evaluate their business objectives to keep up with the changing technological landscape. Traditional business models use a top down approach may leave the company unable to change, as the business leader is unable to change. â€Å"It is noteworthy that neither Larry Page nor Sergei Brin, Googles founders, has proclaimed himself chief software architect, the badge Bill Gates wears at Microsoft† (Hamel, 2006) Instead the founders have designed a concept the makes every idea stand on its own merits. Internal and external factors such as Globalization, Technology, Innovation, Diversity, and Ethics carry large weight in management strategies and the method in which ideas are executed. Planning Planning is the first of the four management functions. Google manages to plan for their future by recognizing that planning requires research and development. Investing in new technologies takes time and money, and not every cent or minute can be dedicated to research without other sources for income. This is why Google invest in smaller companies to fund the evolution of change in the technological world. So even though the company’s overall growth may experience slow periods the overall income will continue to grow with the acquisition of these multiple smaller companies. Organizing Organizing is attracting people to the organization as well as assembling and coordinating the human, financial, physical, informational, and other resources needed to achieve goals. â€Å"Google is famously elitist when it comes to hiring. It understands that companies begin to slide into mediocrity when they start to hire mediocre people. Googles grueling hiring process, akin to a Mensa test, values nonconformity nearly as highly as genius.† (Hamel,  2006) Google also allows their employees 20% creative time, which is off budget, and off project. This off shift time can attribute to some of Google’s most profitable ideas and software implementation. Providing the creative outlet for the company’s highly creative employees has yielded great results and is part of Google’s overall planning model. Hamel, G. (2006, Apr 27). Management a la google. The Wall Street Journal Asia. Retrieved from http://search.proquest.com/docview/315425991?accountid=35812 The ultimate test of any management team is not how fast it can grow its company in the short-term, but how consistently it can grow it over the long-term. In a world where change is relentless and seditious, this demands a capacity for rapid strategic adaptation. In many cases, companies havent been changing as fast as the world around them.What the laggards have failed to grasp is that what matters most today is not a companys competitive advantage at a point in time, but its evolutionary advantage over time. [Google] gets this. While Googles growth will inevitably slow, theres a good chance that its revenues will arc upward for years. Why? Because its novel management system seems to have been designed to guard against the risk factors that so often erode an organizations evolutionary potential: When power is concentrated at the top, a tradition-bound executive team can hold a companys capacity to change hostage to its own ability to adapt. Thats why it usually takes a financial meltdown and leadership change to set a company on a new course. It is noteworthy that neither Larry Page nor Sergei Brin, Googles founders, has proclaimed himself chief software architect, the badge Bill Gates wears at Microsoft. Rather than assume theyre infallible seers with a divine right to dictate Googles next strategy and the one after that, Messrs. Page and Brin have created a Darwinian environment in which every idea must compete on its merits, not on the grandeur of its sponsors title. Google understands that even as its ramping up todays business model, it has to be buying options on the future by creating a lot of little Googlettes. Evolution demands a lot of new experiments; but experimentation takes time and money, scarce commodities when every hour of time and every dollar of capital have already been  allocated to some mission critical project. Thats why every Google developer can spend up to 20% of his time working on off-budget, out-of-scope projects. This time is more than a perk; its Googles seed corn for the future. The payoff? In one recent period, more than half of Googles newly launched products could trace their origins to a 20% project.

Liberal, Conservative, and Socialist Ideals vs. Feminism before the 20th Century :: Sociology Sociological Women Paperes

Liberal, Conservative, and Socialist Ideals vs. Feminism before the 20th Century Tales from the beyond, story one: a parent binds his baby girl's feet in China, so it will not grow more than five to six inches because small feet in women are a sign of elegance; story two: a wife is burned alive in India, so she can accompany her husband in death. Are these stories? No, things like this really happened in the past. They are part of the reason that contributed to the birth of the Women's Movement in the 19th century. This movement was also known as the Feminist movement because its foundation came from feminism, an ideology that developed in the 19th century, and whose main goal was to gain equality for women. The goals of the Women's Movement in the 19th century where: to get the vote, to archive equality in property rights, access to education, access to jobs and fair pay, divorce, and children's custody. These ideals had been around for a while, but the 19th century was the perfect time for them to develop. During the 19th century, nations were going throu gh radical changes; countries were adopting new ways of life based mainly of one of three ideologies: liberalism, conservatism, and socialism. The development of one of these ideologies, and the success of feminism in a country went hand in hand, and it is by analyzing the similarities, and differences between feminism, and each of these ideologies that we can see why feminism was most successful in liberal countries. Moral, political, and social are the three cores of liberalism, and the ideas in each core have a very similar resemblance to the ideas the feminist movement was trying to promote in the 19th century. Liberals believe that individuals had the right to personal liberties, which included the freedom to think, talk, and worship. Feminist believe women had the right to think, to have an opinion different from that of their husband, or fathers. The faith in total freedom, and equality for the individual that liberals, and feminist shared came from their faith in education. Their theory was that if individuals were educated, then they could be trusted to make the right decisions, decisions which would then in return helped make a better society. Adam Smith, writer of "The Wealth of Nations" considered the bible of liberal economics, believed in that theory, he expressed that "each person,.
