...Failures Paper Charles Persinger University of Phoenix POS/355 Jeff Rugg April 28, 2014 Simply put, distributed computing is allowing computers to work together in groups to solve a single problem too large for any one of them to perform on its own. Distributed computing is not a simple matter of just sticking the computers together. For a distributed computation to work effectively, those systems must cooperate, and must do so without lots of manual intervention by people. This is usually done by splitting problems into smaller pieces, each of which can be tackled more simply than the whole problem. The results of doing each piece are then reassembled into the full solution. As handy as a distributed system can be there are a there are four main issues you could face: Operating system failures, Hardware Failures, Omission Failures and Byzantine Failures. Crash failures are caused across the server of a typical distributed system and if these failures are occurred operations of the server are halt for some time. Operating system failures are the best examples for this case and the corresponding fault tolerant systems are developed with respect to these affects. Hardware failures used to be more common, but with all of the recent innovations in hardware design and manufacturing they tend to be fewer and far between with most of these physical failures tending to be network or drive related. With more hardware the probability goes up that there will...

...Failures Adam Cain POS/355 2/6/2014 Randy Shirley Failure is not an option! This is what I have been told growing up and while I served in the Marine Corps, but as I found out in this assignment, failure is 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...

...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”.

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).

...Operating System Analysis Paper Team A: , POS/355 August 25, 2012 Demetrius Fluker University of Phoenix Operating System Analysis Paper When ruminating over which operating system for a home, business, or office computer or network of computers, it is vital to evaluate all areas of the different operating systems options. The key system options to compare and contrast when evaluating Microsoft Windows XP, Microsoft Windows Server 2003, and Linux operating systems are to consider the system requirements, the different editions available, security features, system features, updates and support, user interface, and cost effectiveness. Moreover, the best fit operating system can be determined depended on the individual’s or organization’s needs. Operating System Requirements Windows XP The system requirements for Windows XP Home Edition and Professional Edition are the same. These requirements are a PC with a 233 megahertz or higher (a 300 megahertz + processor speed is recommended), 64 megabytes (MB) of RAM or higher (128 MB is recommended), 1.5 gigabytes (GB) of available hard drive space, a video adapter and monitor that is Super VGA (800x600) or higher-resolution, CD/DVD-ROM drive, keyboard, and mouse/pointing device. The Windows XP Starter Edition has different system requirements. These are 233MHz processor or better, 256 MB of RAM, Super VGA (800x600) video adapter and monitor, CD/DVD-ROM drive, keyboard, mouse/pointing device, DirectX 9 graphics with 32 MB...

...Construction Management and Economics (May 2004) 22, 347–356 The development of the construction legal system in China LAM YOW THIM and CHEN ZONGGUI School of Civil and Environmental Engineering, Nanyang Technological University, Singapore Received 2 December 2002; accepted 29 May 2003 China has been developing at an amazing speed since it carried out reform and open-door policy in 1978. Construction industry is playing a leading role in the rapid Chinese economic development. At the same time, China has also worked hard to encourage overseas investors to expand their investment in the construction industry. With its development over the years, China has established a legal system for governing construction activities. To participate in such a major market in the world, it is important to understand the legal system governing it and the impact of China’s joining the World Trade Organization. The Chinese construction laws and practice are still very different from the international norm. If foreign participants are to make a success out of doing business in China, they must understand the Chinese way of life. Particularly, they must prepare to adapt to an environment where new rules are created as circumstances and situations change.

...SPECIAL ARTICLE Challenges to Financial Inclusion in India The Case of Andhra Pradesh S Ananth, T Sabri Öncü Focusing on the institutional challenges to financial inclusion in Andhra Pradesh, this paper argues that it is the inability of formal financial institutions to meet the specific needs of the poor that has enabled informal service providers to fill the vacuum. Without a paradigm shift, especially on the part of banks, financial inclusion is bound to fall short of expectations. It proposes that the banking sector should look at efforts to expand inclusion not as a capital cost or as a charitable expense, but as a long-term investment in the future. The soundness of such an investment is borne out in the success of individual business correspondents in some districts of the state. 1 Introduction The views expressed in this paper are those of the authors and do not necessarily reflect views of the Centre for Advanced Financial Research and Learning. S Ananth and T Sabri Öncü (Sabrioncu.cafral@rbi.org.in) are with the Centre for Advanced Financial Research and Learning, Mumbai. Economic & Political Weekly EPW inancial inclusion has become central to Indian policymaking over the past few years and various attempts have been made to expand its scope. Despite these attempts, the challenges to financial inclusion remain formidable. These attempts and challenges have to be not only examined in the context of an increasingly globalised economy, of expanding markets...

This paper presents additional insight into who entrepreneurs are and how their characteristics relate, and how those relationships might impact their behavior. We have studied selected entrepreneurial characteristics and their relationship to optimism, realism, and pessimism. The study shows that some entrepreneurial characteristics are positively related to optimism and realism and negatively related to pessimism. Key Words: Entrepreneurship, Psychology, Entrepreneurial Characteristics, Optimism, Realism, Pessimism 2 Entrepreneurial Characteristics, Optimism, Pessimism, and Realism – Correlation or Collision? Introduction There is a common argument among researchers regarding if entrepreneurs are optimistic, and if optimism relates to other characgteristics of entrepreneurs. The purpose of this paper is to explore and examine the relationship between entrepreneurial characteristics, optimism, realism, and pessimism. For many years, researchers have identified unique characteristics of entrepreneurs – confidence, independence, being in control, risk taking, creativity, just to name a few. Literature has also discussed...
