...POS/355 March 11, 2013 Bhupinder Singh Failures Paper The distributed systems are unique in that it’s executions of the application of the protocols are to coordinate on multiple processes on the network, they have their own local memory and it communicates in entities with each of them using a massage passing mechanism. They also have their own personal users to them that they can use for personal uses. What are shared across the distributed systems are the data, processor, and the memory that can achieve those tasks when processing information. The distributed system has features to help achieve in in solving problems and issues with software and programs, when being useful with the distributed system is not very easy; its capabilities are the components, than just the stand alone systems that are sometimes not as reliable. Because of the complexities of interactions between running the distributed systems, it must have special characteristics like the fault tolerant; this can recover from component failures without performing incorrect actions. Recoverable is where failed components can restart and then rejoin the system after the cause failure has been repaired. The failure on a distributed system can result in anything from easily repairable errors to a catastrophic meltdown. Fault tolerance deals with making the system function in the presence of defaults. Faults can occur in any one of components. In this paper we will look at the different...

...Comparison and Contrast of the Professional Stories of Michael Dell and Andy Grove Melissa A. Honea Northcentral University ABSTRACT Michael Dell and Andy Grove were both successful businessmen who use different approaches to their businesses. Both men had success and failures that shaped their business into the successful company’s they are today. Michael Dell tried a new approach to his business that he quickly saw was a failure. He realized that the approach he currently uses is the most successful for his company. Andy Grove made his company successful twice. While in the memory business he had 100 percent of the market share. He learned a hard lesson when his company was pushed out of its market share by competitors. The company had to quickly find a new niche. After three years, the company was successful again. Comparison and Contrast of the Professional Stories of Michael Dell and Andy Grove Michael Dell Michael Dell became an entrepreneur at the age of 12 when he advertised his business “Dell Stamps” in a local trade journal. While in college, Dell turned his dorm room into a personal computer laboratory and started selling them. In 1984, Dell started Dell Computer Corporation. In 1988, the company went public raising $30 million at its initial public offering (Krames, 2003a). Dell’s philosophy is to put the customer at the center of his business. All computers are custom ordered by the customer. The production process does...

...take a test whether I study or not. 2. What are your first memories of being in a testing situation? What were your feeling, and why? My first memory of being in a testing situation is in high school. It was finals and I needed to pass this one course to graduate. It was a course that I detested, and I was horrible at it. This course was Trigonometry. I am not good in math period, but this course was a requirement. I felt that I was going to fail the course, and it was going to be a setback. It was a depressing feeling. 3. What make a test “good” and “bad” from your perspective? What make a test good is knowing what kind of test it, what is covered and how much a percentage is geared toward that test. How do I know that the test is good is when the instructor lets you know what is going to be on the test. A test is good when much preparation and work goes into it. The format or the structure of the test also make it good. When I think of a bad test, it mean no preparation, no work or study when into taking the test. A bad test is a test that is not put together well. The organization is not good and the test is very confusing. It can be a bad test when the person taking the test is ill-prepared. 4. What factors contribute to your success or failure on a particular exam? Which of these factors are under your control? The factors that contribute to a success or failure on a particular exam are the preparation time, how much notes you take...

...discovered to possess. 10Xers are leaders who built companies that started from a position of vulnerability, rose to beat their respective industries by at least 10 times, and did so in the midst of instability, crisis, and uncertainty. They are characterized by three behaviors: fanatic discipline, empirical creativity and productive paranoia. Towards the end of the book, the authors also explore luck and how much of an influence it has on successful or unsuccessful outcomes. They hone in on the notion of return on luck, arguing that fortune is but one variable in the equation of success. “Defeat is not the worst of failures. Not to have tried is the true failure.” –George Edward Woodberry What is success? And more importantly how does one obtain it? Some would be surprised to know that some of the greatest success stories came only after a myriad of failures. But it is no surprise that the recipe for success is a complicated one. Jim Collins and Morten Hansen spent nine years researching what it takes in order for a company to be successful and thrive in this fast-paced ever changing world we live in. In the book Great By Choice Collins seems to have decoded a large part of the recipe for success that can easily be summed up in four words, “fire bullets, then cannonballs.” In the midst of firing these...

...According to Webster, a failure is classified as “an omission of occurrence or a state of inability to perform a normal or specified function that ultimately leads to a lack of success.” In the light of operating systems, this topic can be extremely important to a customer and designer of said system. Failures in a system can create catastrophic events that are costly in both monetary and emotional aspects. Faults within a system can be different in nature and can continue to wreak havoc on the system or to do nothing in some cases. Failures in distributed and centralized system can be specific in nature; however a generalized topic can describe the majority of these failures across the system. There are four types of failures in distributed systems that can affect functionality; but two of these four specific failures that can affect centralized systems as well. The general failures include: halting type failures, byzantine style failures, omission failures, and failures related to network issues. While all of these are important some of them affect a system more violently than others. The first types of failures to discuss are halting failures. These types of failures can be frustrating in nature since they affect most of the system and do not allow the operator to really investigate without rebooting the entire system. These failures essentially freeze the system without allowing any action to alleviate the issue. There can be many reasons for a halting failure such as hardware...

...Failures of a Distributed System POS/355 July 25, 2013 Failures of a Distributed System In the words of Adam Savage from Mythbusters, “failure is always an option”. This holds true when talking about a distributed system, which is a computer network like a Wide Area Network (WAN) or a Local Area Network (LAN). Distributed systems is defined as a software system in which components located on networked computers communicate and coordinate their actions by passing messages (Coulouris, Dollimore, Kindberg, & Blair, 2012). This allows the computers or even devices like smart phones and tablets, to share resources like printers, hard drives, and even internet access. A centralized system is a computer that is by itself, one that is not connected to a laptop. Think of a centralized computer as one of the spy computers in movies, like Mission Impossible. These systems can and will fail, while sharing some failures; a distributed system has more components that could fail, leading to them having more problems. There a many things that could fail on a distributed system, this paper will cover four of them, starting with hardware failure. Video cards, network access card, hard disk drives, solid-state drives, memory, and power supply units (PSU), these are all pieces of hardware that are in most of the computers sold today, and they can all die at a moment’s notice. Some of these items, if they failed would not affect the network or distributed system at all, like a video card...

...Topic 1: Discussion Question 2 I reminisce to the excitement of the first day of school as I begin the next chapter of my educational journey. The sweet feeling of unknown, the butterflies in the stomach bring about childhood memories. I am looking forward to expanding my knowledge, the joy of overcoming the challenges and most importantly, earning my BSN. I have my goals set clearly before me and my motivation is strong. I know I can overcome my fear of failure as I have done in the past. My fears almost caused me to give up during my LPN to RN bridge program. I felt overwhelmed and lost confidence in myself. Thankfully I had a strong support system. I was able to refocus on my goals, prioritize and utilize my resources to overcome my fears of failure and succeed. With hard work and determination I regained my confidence and drive to become a professional and a scholar. From that point there was no turning back. I have too much at stake to allow self-doubt to interfere with my goals. Although I encountered a setback during my bridge program I was able to complete it and earn my associate degree. I am glad I had that experience. It made me more confident in myself and more aware of my strengths and weaknesses as a student. I think it is naïve for a person to believe they will never fail. That mid set handicaps a student’s mind. I feel that knowing and accepting one’s fears is the best way to not fall into their depths. References: Lake, A., & von Baeyer, C. (2005)...

...A woman named Alexandra Elle once said “I am thankful for my struggle because without it, I wouldn’t have stumbled upon my strength.” Accepting defeat is perhaps one of the most difficult challenges to go through. The mortification is tough to overcome after experiencing failure. Failure comes in many different forms and people have different ways of handling it. For myself, my failure came recently after I was not reelected for senior class president. After I found out I was no longer a part of student council, I had one question to answer: what do I do now? Throughout my years at high school, I have held a variety of positions in student council. I was class reporter my freshman year, class vice president my sophomore year, and class president...

...1 Valedictory Address Time strides with leaps and bounds that our six-year stay in this school has finally come to an end. For us graduates parting from our Alma Mater is a nostalgic climax we can never forget. It is here in this school that we are molded. It is here where we met our friends as well as our enemies, shared with joys and laughters, experienced love and sorrows, success and failures and many other changes that occur in our lives. Graduation doesn't mean triumph, it implies responsibility and burden to us so we should think of a way to surmount lifes innumerable struggle to build a better tomorrow. We should think that graduation does not hold a complete bright promise. It grims along a few grim prospects, fear of the uncertain future. It is not the end of struggle but a prelude to an even tougher competition that is the battle to survive in the real world. It is then imperative that we arm ourselves for this battle while still we can. We should strive hard to make good with our studies. We should aim high for there is no plave in this world for under achievers. This is for us graduates for we still have the choice. There is no turning back for us. We have to face the world that awaits us and see for ourselves what it holds in store. Graduation day is therefore a mixture of happiness and sadness It is the most awaited moment for all of us. After all the hardships and struggles we had experienced, the six years of endeavors is almost over without...

...to which it was built, it is considered to be experiencing fault. The two fundamental approaches to constructing a reliable system are fault tolerance and fault prevention. (Tamer M. O.,1999). While fault tolerance measures constitute design time features to be built in system which detect and remove faults that can result in system failure; fault prevention is the system analysts’ task to ensure a reliable system after it has been implemented and is under use. Analyze risks involved. Identify the probable points of failure of the system and how far reaching could be the impact on business. Take steps to ensure maintain business continuity if the system will exhibit faults, and implement monitoring systems for critical components such as operating system performance, database stability monitoring and hardware maintenance. Ensure safe transactions. Incorrect input data or database deadlocks can lead to system failures. While data validation is strictly recommended at client level, database design should implement transaction abort on fault detection. Maintain redundancy. Hardware and software failures are the most common forms of system failures. Keeping a second set of servers for load balancing and a database replication server can make the system scalable to take on additional load and also act as buffer for business continuity if a fault is detected in primary system. Identify symptoms of...

...The Memory or The Statue Americans are fighting vigorously more and more each day to stay ahead of their futures. With our own president saying our country is in its greatest depression, people are beginning to have to ask themselves what type of opportunist’s are they. Many people in America find it quite easy to settle, and become content with the America dream. Then our economy does what it’s currently doing and people lose stability. Now they have to choose how hard they want to fight to keep their style of living. There are three main types of opportunists in the world and they are categorized as Type A, Type B, and Type C. Type C: Those whose stand back and watch others achieve success; Withholding dreams due to fear of failure. Type C opportunists are the most troublesome group of opportunists during times of needed growth. Type C opportunists usually show signs of low self-esteem, and have a problem with social acceptance. It is said that Type C opportunists develop this personality in the teen years and can be brought on by many factors. The Type C opportunist is not a problem though in the workforce of corporate America for a few reasons. They may show little signs of leadership, but these individuals do quite well at handling low-level jobs that keep the business’s running. Type C people may never be leaders, or own their own business, but it does not mean they lack a work ethic. Many of them are very hard workers, but are too afraid to take the next step into...

...Victoria White Distributed System Failure December 16, 2013 There are two types of system structures that can be created. The first is a centralized system, which consists of one or more major hubs. All communication is processed through these hubs. This system setup provides security, to an extent, since all of the computing is done through a single computer. However, it also creates a single point of failure, if the main computer goes down the system is down. A distributed system is a collection of processors connected by a communication network. The processors may include microprocessors, workstations, minicomputers, and large computer systems. These processors are known by a few different names, sites, hosts, nodes, computers, and machines. There are a couple major reasons for creating a distributed system, these reasons include resource sharing, communication, reliability, and computation speedup. However, there are a few failures that may occur with a distributed system these failures include link failure, host failure, storage media failure, and scalability. The first failure, link failure, occurs when the connection between two parts of the system fails. When this takes type of failure takes place the two parts of the system connecting can no longer communicate with each other. To detect link failure, a procedure known as handshaking is done. With this procedure first the host that is still functioning will continue to send I-am-up messages to the other host. After...

...day without a hug never seems right to her. I remember when I’m standing out of the window. I wanted to play with a couple of girls who were jumping rope. My mother wouldn’t let me jump rope with them, and I started to cry. Nobody seemed to notice me when I ran off by myself.” the memory depicts a sense of rejection and hurt. Although Honey Grace tries to play with the other girls, her effort ends in futility. The memory evokes painful feelings, but there are also features of the remembrance which present more hopeful aspects. Honey Grace’s high degree of activity is evident and she seeks to be a part of a constructive experience with others. Basic mistake Emotional perfectionism: I should always feel happy, confident, and in control of my emotions. 2. Performance perfectionism: I must never fail or make a mistake. 3. Perceived perfectionism: People will not love and accept me as a flawed and vulnerable human being. 4. Fear of disapproval or criticism: I need everybody’s approval to be worthwhile. 5. Fear of rejection: If I’m not loved, then life is not worth living. 6. Fear of being alone: If I’m alone, then I’m bound to feel miserable and unfulfilled. 7.

...“Failure is the key to success; each mistake teaches us something.” When I walked onto the campus at Virginia Tech in 2011 failure wasn’t even on my mind. I had finished high school with honors and the dream of becoming a pharmacist. I had a plan (the same one since fifth grade) and knew that nothing was going to change. Little did I know that pharmacy was far from my passion, medical based chemistry and biology were some of the most difficult courses I had ever been faced with and I came to realize that I had a lot of thinking to do. I left Virginia Tech with an abysmal GPA and decided a year at home working and going to community college were my best options. I had to immediately get over my pride and accept the fact that I had hit the road running and fell flat on my face. The year I spent at home I went to J.
