The Five State Processor Model
Our lives have become very dependent on computers. We use them for EVERYTHING from playing games, being the brains behind our phones to running our automobiles. As complicated as these have all become they all still depend on a microprocessor to make the decisions happen and all microprocessors have the same five state model used to make decisions on what runs when. These five states are new, running, ready, blocked, and exit (Sinapova, 2001). This paper will cover provide a brief explanation of each of these states.
The first state we will cover is the “new” state. The “new” state can simply be described as what a process becomes when it is first accessed by the user. You can think of this as when you double click an icon on your desktop. When the user double clicks the icon the processors receives a request to start up a new process and depending on what the processor is already doing will depend on how quickly it answers the request to start that application.
The second state we will cover is the “running” state. The “running” state can be thought of as a process that is currently being attended to by the processor. A simple example of this would be using the calculator function of the operating system and having it execute a simple math function.
The third state we will cover is the “ready” state. The “ready” state can simply be thought of as a process waiting to happen. The process will stand by until the processor has the time and/or resources to transfer the “ready” state process to a “running” process and execute the needed task.
The fourth state we will cover is the “blocked” state. The “blocked” state will usually occur when a “running” process runs into an error of some sort. An example of these errors could be an…...

The Five Forces Model of Competition

...The Five Forces Model of Competition The model above is known as the Five Forces Analysis which was designed and created by Michael Porter of Harvard Business School. Each shape defines the five forces that shape competitive rivalry and is relevant to industry profitability. Each new entrant to an industry faces competitive pressures from: • Buyer bargaining power and seller buyer collaboration. • Companies in other industries to win buyers over to substitute products. • Supplier bargaining power and supplier-seller collaboration. • The threat of new entrants into the market. • Rivalry among competing sellers to attract new customers. For a new entrant to the automobile industry there is generally a very low threat. In order for a new entrant to be successful they must be able to mass-produce. Due to the expense of mass production, a new entrant must have a large amount of capital to compete in the automobile industry. Buyers and customers both have high bargaining power when purchasing an automobile. Buyer power is strong when a consumer has a multitude of products to choose from. An example would be choosing to purchase a Ford Expedition or Chevrolet Tahoe. Both are similar in size, gas mileage per gallon, seating and engine size. Each vehicle is produced by a different manufacturer which gives the consumer the ability to create competition. In addition manufacturers are forced to create quality automobiles in order to maintain......

Porter's Five Forces Model

...American Military University Abstract Porter’s Five Forces Model is a holistic approach towards competitive strategy. The model provides a framework for the strategic direction of management teams that are seeking an edge over their competitors and additional factors that may undermine profits. The model displays the dynamics between the competitive rivals, buyer’s bargaining power, suppliers, new entrant’s threat and substitutes. The implementation of Porter’s Five Forces Model is crucial on international business practice in order to establish a successful overseas operation and reduce cost of expansion. Global business expansion has become a common practice. Modern organizations are prone to take advantage of international attractive markets that are highly profitable and offer incentives for foreign companies. Implementation of the model increases the chances of success for firms that are considering branching out or simply starting a new company overseas. The Company’s management strategic vision also benefits from Porter’s Model because it points out the forces that affect the organization’s profitability. However, Porter’s modeling techniques have some limitations such as the absence of providing meaningful advice for preventive actions and profitability based solely on fighting competitors without taking in consideration opportunities of competitive strategic alliances. In conclusion, Porter’s Five Forces Model influences the profitability,......

... Michael Porter’s Five Forces Strategic Competitive Model By Rajshekhar.V IGTC 2012-14 Roll No. 29 Indian Automobile Industry The Indian automobile industry is the tenth largest in the world with an annual production of approximately 2 million units. Indian auto industry, promises to become the major automotive industry in the upcoming years and the industry experts are hopeful that it will touch 10 million units mark. Indian automobile industry is involved in design, development, manufacture, marketing, and sale of motor vehicles. There are a number of global automotive giants that are upbeat about the expansion plans and collaboration with domestic companies to produce automobiles in India. Porter's five forces model on Automobile Industry * Barriers to Entry – Automobile Industry is a capital extensive and labor extensive industry. The emergence of foreign competitors with the capital, required technologies and management skills began to undermine the market share of many automobile companies. Globalization has lead to huge investments and has caused businesses to move from national and domestic markets to a worldwide environment which is a huge factor affecting the auto market. Off late, it is becoming easier for foreign automakers to enter the Domestic market .Automobiles depend heavily on consumer trends and tastes. While car companies do sell a large proportion of vehicles to businesses and car rental companies (fleet sales), consumer sales is the largest source......

...Five Forces Model Porter’s Five Forces Model was created to act as a framework for industry analysis and business strategy development. Porter singled out five different forces that impact competitive intensity which portrays an image of the overall attractiveness and profitability of a market. To aid in our evaluation of Nestle and its status in the industry, we will apply Porter’s Five Forces Model to the company. Threat of New Entrants The food processing industry is very large and competitive; it is not uncommon for firms within the industry to do quite well. As a result, many companies enter into the market every year in an attempt to gain a portion of the profitable market. Luckily for Nestle, the company has been around for over a century and boasts a long history of quality products and consumer satisfaction which has allowed the company to obtain a considerable share of the market. As a result, new entrants into the industry must attempt to seize a portion of Nestlé’s market share in order to survive. Essentially, Nestle is constantly a target and so the threat of new entrants is moderate. Threat of Substitute Goods Due to the nature of the industry, Nestle is beset with the threat of substitute goods. From bottled water to lean pockets, there are arrays of similar products that compete directly with Nestle. It is vital for Nestle to continuously find new ways to improve its products as the competition is so fierce. In recent years, Nestle has focused...

Porter's Five Forces Model

...Porter's Five Forces Model Porter's five forces analysis is the structure framework for industry analysis and business strategy development. (Porter, M.E. 2008) Using Porter's five forces analysis is a way to figure out the different firms competition levels and force of said "attractiveness" of a market. "Attractiveness" being used in the context of the end all, be all of a industry's profitability. On the other hand, an unattractive industry refers to the combination of all five of the forces acting to drive down the overall profitability. (Porter, M.E. 2008) Three of the five forces of Porters refer to the competition derived from external sources, the remaining two are both internal threats. Porter looked at the forces as the micro environment, that way it would highly contrast against the more commonly known term "macro environment". These forces are close the company and greatly affect the company's ability to serves its customers and make a profit also. If a change were to occur it will normally result in a business having to re-evaluate and re-asses the marketplace to see what overall changes in the company would have to be made to keep up with the market. This however, does not go to say that every firm or company will have the same amount of profit. A company with clear objectives is more likely to achieve a profit over a company with less clear objectives. It comes down to the company's core competences and how the company comes together to work......

Five Forces Model

...Porter five forces analysis is a framework to analyse level of competition within an industry and business strategy development. It draws upon industrial organization (IO) economics to derive five forces that determine the competitive intensity and therefore attractiveness of a market. Attractiveness in this context refers to the overall industry profitability. An "unattractive" industry is one in which the combination of these five forces acts to drive down overall profitability. A very unattractive industry would be one approaching "pure competition", in which available profits for all firms are driven to normal profit. This analysis is associated with its principal innovator Michael E. Porter of Harvard University (as of 2014). Porter referred to these forces as the micro environment, to contrast it with the more general term macro environment. They consist of those forces close to a company that affect its ability to serve its customers and make a profit. A change in any of the forces normally requires a business unit to re-assess the marketplace given the overall change in industry information. The overall industry attractiveness does not imply that every firm in the industry will return the same profitability. Firms are able to apply their core competencies, business model or network to achieve a profit above the industry average. A clear example of this is the airline industry. As an industry, profitability is low and yet individual companies, by applying unique......

Porter Five Fold Model

...Porter’s Five Forces model The five forces model of analysis was developed by Michael Porter to analyze the competitive environment in which a product or company works. It identifies the five most common threats faced by firms in their local competitive environments and the conditions under which these threats are more or less likely to be present; these forces are the threat of entry, threat of rivalry, threat of substitutes, threat of buyers and the threat of suppliers. These threats increases a firm's costs, decreases a firm's revenues, or in other words they reduces a firm's performance. Industry Structure This model analyzes industry structure and by definition an industry is a group of firms that market products which are close substitutes for each other. Guardian Life Limited offers services such as Individual Benefit Plan and Employee Benefit Plan. The individual benefit plan includes benefits such as Critical Illness Plans, Traditional Insurance Plans, Universal Life & Equity Linked Plans, Interest Sensitive Plans, and other Plans. Also the Employee benefit plan includes: Group Life Insurance, Group Health Insurance, and Pension Administration. We will now state how the 5 forces model applies to Guardian Life Limited. Threat of Entry One reason why new entrants pose threat is that they bring additional production capacity. Unless the demand for a good or service is increasing, additional capacity holds consumers’ costs down, resulting in less revenue and......

Porter Five Model

...PORTER’S FIVE FORCES MODEL Porter’s five forces is a framework developed by economist Michael E. Porter to analyze level of competition within an industry and business strategy development. Further, it determines the probability and attractiveness of a market or market segment. In 1979, Porter was an associate professor at Harvard Business School, the Porter’s framework maintains that the attractiveness of a market segment is determined by five competitive forces namely: 1. Threats of potential new entrants 2. Bargaining power of buyers 3. Bargaining power of suppliers 4. Threats of substitute products 5. Rivalry among competitors 1. Threats of potential new entrants The threat of new entrants is usually based on the market entry barriers, which can be said to provide obstacles for newcomers to gain a foothold in any given industry. These barriers can take many different forms. Briefly, it can be said that entry barriers exist whenever it is difficult or not economically feasible for an outsider to copy or imitate the existing player’s competitive capabilities. Common forms of entry barriers are depicted below: * Economies of scale * Capital requirement of entry * Access to supplies and distribution channels * Customer or supplier loyalty * Lack of experience in industry * Legal restrains such as trade barriers 2. Bargaining Power Of Buyers Important determinants of buyer power are the size and the......

...Five Forces Model Competitors and their Relationships • Dick’s Sporting Goods • Hibbetts • Sports Authority • Foot Locker • Wal-Mart Threat of New Entrants The threat of new entrants is moderate. It is relatively easy for a company to enter this market because there are not a lot of legal barriers. But a smaller company that has just entered the market would have a tougher time competing with some of the larger companies – an obvious reason being that larger companies can have larger inventories. Another reason is that larger companies can do things to weaken the smaller companies, such as offer discounts, sales promotions, and increase spending on advertising. Since most of the companies in this industry are competing on price, it would be difficult for the smaller company to keep up with these tactics and remain profitable. So in short, the threat is there, but it isn’t a huge one. Threat of Substitutes The threat of substitutes is high. One example is online shopping. Customers can easily buy just about anything they could find in a sporting goods store on websites such as Amazon.com, eBay, and Craig’s List. These substitutes are readily available and there is also a good chance that they will be at competitive prices as well. The ease of the internet and good chances of finding good deals makes the willingness of switching to substitutes higher. Buyers Buyer bargaining power is strong. This is for a number of reasons, but a few are: • The......

Five Step Model

...Applying the Five Step Model HUM/115 University of Phoenix Amy Riddle The five step model begins with identifying the problem. In order to do that is by understanding exactly what is going on. Once the problem is identified, the rest of the process will feel more manageable. Discovering how the problem all started is the next leading thing to the process. Thinking critically will help anyone start a list. When the list is created you can now figure out how to solve the problem that you are having. Now it’s time to evaluate what is the best option to the solution. Critical thinking becomes your best tool here. The best part of it all is doing what needs to be done to get the problem resolved. Almost everyone is confronted with financial problems during his and her lifetime. Whether these problems come from major college debt, bankruptcy or not being able to find a job that sustains your lifestyle, everyone needs to face his or her financial problems and deal with them appropriately. Ignoring financial problems only makes them worse, but bracing the issue won't always be the easiest thing to do, but in the long run, it can significantly improve your life and teach you about responsibility. You should treat everything you do like a financial investment. This allows you to make good spending decisions as you work toward fixing your financial problems.

...The Five-Step Model Nicola .S. Hershey HUM/115 February 01, 2016 Patience Johnson The Five-Step Model There are five steps to overcome our problems. The first step is the most imperative and that is to identify the problem in details and what you hope to gain from solving this problem. “We cannot solve a problem unless we define it well” (kirby & goodpaster, , p. 288). Secondly, know your alternatives, your other options and of course your limitations. Thirdly weigh your alternatives in terms of their advantages and disadvantages. Fourth make your choice on what solution you will use to overcome your problem. Last but not least revise how your solution works for you and how well your final goal will help you. Education I yearn for my Bachelor’s Degree like I need my next breath. I have a major problem in attaining one and that is my time management skills. I will master this, and hold my degree in my hand by the end of this course. ”To live is to decide, and to live fully is to decide well.” (kirby & goodpaster,, p.320). I could easily just throw my hands up and forget about achieving my goal, which would not solve my problem because I would still have that deep rooted desire to get my bachelors. I can manage my time better by asking for help when I need to, I can also ask if the deadline for a particular assignment is set or if extensions are......

Five Factor Model

...Psychology 204 November 6th , 2015 Five Factor Model Paper According to my results from the Five Factor Model test I completed I am a kind and trusting person who has a wild imagination, who often feels anxious and or irritated. My highest scores were in agreeableness, and openness to experiences. According to my text book people who score high in the agreeableness category tend to be “sociable and easy to get along with, and those who score high under openness to experiences are intellectually curious, and untraditional” (Lilienfeld, 2011). My lowest scores were in emotional stability and extraversion, scoring low in these categories means that I am likely to be anxious, irritated, and shy. I believe that the results are consistent with how I see myself. I have come to accept that I am a sensitive person who feels shy and closed off when trying to integrate with a new group, especially big groups. Although I am shy in big groups I do well in dyads, I feel less anxious in small groups, and many people have said that they enjoy confiding in me because they find me easy to talk to. Personality is complex and it varies between each person because our personalities have many dimensions and layer, but I think that this personality test kind of covers all the bases. When I compare my results to the table of Portland State University college student norms I see that my means tend to stay mostly moderate compared to the norms.
