Assignment In Client Server Architecture Information Technology Essay

Assignment In Client Server Architecture Information Technology Essay This report focuses on understanding the problems being faced by the Information System (IS) department of Hures as well as other Organisations dealing with human resource and management. Such organizations, private or public, continuously collect and process data (information) using technologies available at an increased rate and store the information in computerized systems. To maintain such information systems becomes difficult and extremely complex, especially as scalability-issues arise. Such problems identified are required to be sorted and find out the solutions. Therefore from the scenario given, the measures were taken into considerations to minimize problems in communication mechanism. The client server architecture was established in the beginning to improve productivity, efficiency and information handling. Nevertheless, the Hures Information System department experienced difficulties as the stored information grew leading to the need of establishing peer to peer architecture, intranets and extranets for security purposes. QUESTION ONE Do you think the problems faced by Hures are unique? Why or why not? The difficulty faced by Hures IS department is not peculiar to them rather the underlying technology. In a distributed environment they were working on, the client server technology had problems when it comes to the extension or scaling servers to accommodate additional loads that were initially not envisaged. Client-server architecture consists of series of clients connected to a common server mounted at some remote or nearby location. Hence when there are load increments in the distributed environment, it usually tends to cause problems that make the architecture difficult to scale accordingly. Moreover, for all users on the network the rate of data transfer might go down, and sometimes a powerful and expensive computer needs to be installed and integrated into the system in an attempt to improve scalability and availability of the server. Nevertheless, for every application under heavy loading, numerous computers may be needed. It is customary to utilise one computer to each server application under medium loading, so as to prevent the extent of damage, for example in the occasion of system failure or violation of privacy and security. Client and servers when connected together to form a network that would facilitate better communication is referred to as a client server architecture. A client is an application or system that accesses a (remote) service on another computer system known as a server by way of a network. Hence servers by their operation receive a message from client and work on them and then return the responses to the client. For instance, file server, web server, mail server and web browser are servers and client respectively (Harkey et aL, 1999). QUESTION TWO Suggest alternative architectures that could be used to overcome the problems faced by Hures current Client/Server technology. Increasingly need of users accessing to network resources (i.e. information) virtually for anything held on a database through a common interface. The network supports between the user and that information. Therefore, distributed system is one of the most ideal for location of resources or database transparency. In general, a server and client systems consist of two major parts which are software and related hardware. On a controlled and shared ground to the clients, servers host resources and make them available. This allows access to server content to be controlled in a much better and secured manner. Basically, client/server architecture is a two tier technology which means that it has two nodes namely a client and a server. In order to improve communication between the client and the server, a third node or interface called a middleware is introduced between the client and the server. This is technically a better design as the middleware which is a form of software between the client and the server processes data for clients such as web browsers e.g. internet explorer, mozilla firefox and safari which are all web client. Middleware store data for user applications enabling a comparatively better design that facilitate server scalability as the processing of requests has been separated by balancing the load on different servers (Harkey, et al, 1999). The role of Middleware in a Client-Server Architecture is illustrated in the figure below: Introducing the middleware results in the design of a three-tier architecture which later can be extended to an n-tier. The n-tier architecture has the disadvantages of impacting or increasing traffic congestion and reducing the design robustness. N-tier architecture becomes more difficult to run and test software than the two-tier architecture due to device congestion resulting in communication difficulties. The increased load in n-tier architecture could lead to overloading of the network. Apart from the mentioned disadvantages n-tier architecture has number of advantages which include: better security control, increased flexibility, user friendly, easy upgradeability and scalability compared to the two tier architecture (Harkey, et al, 1999) The implementation of an n-tier distributed computing architecture will be a solution to overcome problems faced by Hures. N-tier architecture has the potential to provide better, more timely information across the enterprise at a lower cost than the current combination of PC LAN, two-tier client/server, or mainframe applications that have been developed in most organizations. For n-tier architecture to be effective, three key components need to be present: Empowerment of the developer to integrate a distributed computing architecture within existing databases, tools, and components. Certainty of efficient network traffic. Mechanisms to handle load balancing to distribute the work across many servers. The n-tier client/server architecture provides an environment which supports all the benefits of both the one-tier approach and the two-tier approach, and also supports the goals of a flexible architecture. The three tiers refer to the three logical component parts of an application, not to the number of machines used by the application. An n-tier application model splits an application into its three logical component types-presentation logic, business logic, and data access logic, where there may be any number of each of the component types within an application. The application components communicate with each other using an abstract interface, which hides the underlying function performed by the component. This infrastructure provides location, security, and communication services for the application components. The n-tier client/server architecture provides an environment which supports all the benefits of both the one-tier approach and the two-tier approach, and also supports the goals of a flexible architecture. The technology should be able to handle future growth. Hures should carry out n-tier client/server technology to solve their partitioning problems. N-tier client/server architecture is an evolution of the traditional 2-tier and 3-tier models, and is suitable for large business applications where many users share common data and operations on them. Peer to Peer The structure of peer to peer network architectures, they do not have a fixed server responsible for blocking and routing request to and from nodes unlike client server architecture. Peer-to-peer networks are simple and easy to implement. However they fail to render the same performance under heavy loads. Distributed computing, instant messaging and affinity communities are all examples of peer to peer network architecture (Deal, 2005). QUESTION THREE One of the suggestions proposed by Hures IS department is the use of intra net web technology. Examine the pros and cons of such an idea. Intranet can be described as a private version of the internet or network connectivity. It is based on TCPIIP protocols configured for a particular organization system, usually a corporation, accessible only by the organizations members, employees, or others with permission to do so. An intranet website looks and acts just like any other Web sites, but the firewall surrounding an intranet fends off unauthorized access. Like the Internet, intranets are used to share information over a network (Douglas, 2005). Intranet is privately owned computer network that utilizes Internet protocols and network connectivity. It is safe and secure in sharing part of organizational operations such as marketing, administrative information or other matters concerned with the organization and its employees. The techniques, concepts and technologies associated with the internet such as clients and servers running on the Internet protocol suite are employed in building an intranet. HTTP, FTP, e-mail and o ther Internet protocols are also applied. Usually intranets are restricted to employees of the particular firm, while extranets tend to have wider scope so that they can be accessed by customers, suppliers or other authorized agents. On the other hand, intranets like other technologies have their own merits and demerits. Below are some of the advantages and disadvantages of this technology (Stallings and Slyke, 1998). The pros and cons (advantages and disadvantages respectively) for Hures using intranet web Technology were accounted for as follows: Advantages Intranet serves as an effective communication tool within the organization, both vertically and horizontally thereby promoting a common corporate culture where every user is accessing the same information available on a common platform. Intranet enables proper time management, since organizations are capable to make adequate information available to employees on the intranet. This way, employees are able to connect to relevant information within the effective time. Increases the productivity levels of workforce by allowing them to locate and view information faster. It also enables them to use applications relevant to the task at hand. Also, web browsers such as Internet Explorer or Firefox help users to readily access data from any database the organization makes available, subject to security provisions within the companys workstations thereby improving services to users. Intranets have cross-platform capability which enables it to adequately support different types of web browsers irrespective of their backbone be it Java, Mac or UNIX. This ability enhances collaboration since every authorized user is capable of viewing information on the site thereby promoting teamwork. Provide a comparatively cost-effective means for network users to access information or data through a web-browser instead of preparing physical documents like manuals, internal phone list or even ledges and requisition forms. Publishing on the web permits critical corporate knowledge such as company policies, business standards, training manuals etc to be secured and easily accessed throughout the company using hypermedia and other web technologies. It facilitates the business operations and management. Increasingly they are being used as a platform for developing and deploying applications that support business operations and decision making across the whole enterprise. (Goldberg, 1996) QUESTION FOUR Do you think the popularity of intranets and the Internet pose threats to traditional Client/Server systems? Intranet and Internet become popular to some extent because they pose some threats to the traditional Client/server systems. It is true that Internet and intranet are both web technologies. A few years ago, the typical office environment consisted of PCs were connected to a network, with servers providing file and print services. Remote access was awkward, and profitability was achieved by use of laptop computers. Terminals attached to mainframes were prevalent at many companies as well with even fewer remote access and portability options. (Silberschtuz, 2004) Currently the secure intranets are the fastest-growing segment of the Internet comparatively much less expensive to build and manage compared to the private networks. Usually private networks are based on proprietary protocols with mostly client server architecture. An extranet creates a secure tunnel between two companies over the public Internet. It is also used to connect remote employees to corporate network by the use of Virtual Private Networks (VPNs). Also intranets are increasingly being used for tools and applications delivery, which facilitate group work and teleconferencing to an enhanced collaboration within the organizations. In order to increase productivity of organizations, sophisticated corporate directories, sales and CRM tools and project management, are all taking advantage of intranet technology (Robert, et al, 1999). Conclusion The problems faced by Hures like other organization including private and public,which are continuosly collecting and storing data in accelerated rate. The above answers on respective four questions discussed on as follows: If the problems experienced by Hures since 1985 up to now are unique or not, comparing to other organizations, such problems experienced were due to growth of business demands in information systems (IS). For example, Hures was forced to downsize the IS from mainframe to Client/Server network resulted in higher efficiency and profit. Nevertheless the problems arise on the server scaling due to loading capacity, forced the company to incur much cost on implementation of distributed environment with more powerful desktop machines. These problems are not unique because all organizations demand changes in IS while they grow up in business. Secondly, the alternative architectures have been discussed about solving the problems of Heures as well as other organizations in information systems. Therefore, distributed system has been suggested which is the most ideal for location of resources or database transparency in networking environment. Thirdly, the intranet web technology as the special network for special organization suggested by Hures IS department, was discussed on its pros and cons which can be relied on for proper construction of networks in any organization. Finally, we have seen that the popularity of intranets and the Internet pose threats to traditional Client/Server systems since the most fastest growing firms with sophisticated systems have taken advantages of Intranet and Internet technologies to facilitate the efficiency in networking and higher production.

How the Atkins Diet Works :: Health Nutrition Diet Exercise Essays

How the Atkins Diet Works   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Dr. Atkins has been at the center of the recent controversy over how to cure America’s obesity problem. America’s desire for a quick fix has caused the introduction of fad diets that claim to work quickly. The Atkins Diet has been deemed one of these fads because of its radical ideas and its straying from the norm of low fat diets. Dr Atkins encourages consumption of foods high in protein and fat while minimizing intake of foods that are high in simple carbohydrates including sugars and breads. But how can this diet be effective at losing body fat if the subject consumes foods that are high in fat? The Atkins diet reduces body fat quicker than normal low fat diets by reducing the amount of food that is consumed and by causing the body’s natural biological functions to burn the body fat that has already accumulated.   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  One reason that the Atkins diet reduces body fat is due to the decreased intake of calories. This reduction in caloric intake is not due to calorie counting but to a reduction in food consumption. The first explanation for this decrease in consumption is that the strictness of the diet severely reduces, if not halts, the occurrence of â€Å"snacking†. These in between meal snacks often consist of simple carbohydrates that are prepared for your easy consumption. Since Dr. Atkins forbids the consumption of simple carbohydrates, he prevents snacking and therefore reduces the amount of calories that enter your mouth. Furthermore, the monotony in the method of the Atkins diet could be a cause of the loss of appetite that is experienced by dieters. Again the strictness of the diet only allows the dieters to eat a small category of foods. This causes the subjects to eat the same meals consistently and understandably become bored with the acceptable foods. Soon this will cause the dieter to opt not to eat rather than eat the same meal again. In addition, the foods that are acceptable according to

Ap Biology Lab 1 Questions

AP Biology Lab 1 Ross Lordo Introduction Questions 1. The solute potential would be -2. 48. If the concentration inside the cell is . 15 M, then would diffusion out of the cell and into the solution of . 1 M. This is due to water potential and the tendency for water to move from areas of high water potential to low water potential. 2. The turgor pressure must be equal to the water potential if there is no net diffusion.The cell and environment have reached equilibrium and the movement of water is equal on both sides. Getting Started 1. Kinetic energy is the energy an object possesses due to its motion. The difference between kinetic energy and potential energy is the kinetic energy is the energy of an object that is already in motion and potential energy is the energy possessed by an object at rest. Potential energy is stored energy, while kinetic energy is energy being exerted. 2.Temperature can affect the rate of diffusion. If the temperature is colder, the rate of diffusion is muc h slower as a result of all particles becoming closer together. If the temperature is warmer, there is much more energy present and therefore allows for the diffusion to take place at a fast rate. The distance a molecule needs to travel across the membrane can also affect the rate of diffusion. If the distance across the membrane is large, then the rate of diffusion will be much slower and vise versa. 3.A high temperature can speed up the diffusion process by providing more energy for the molecules and also for eliminating in double bonds in the phospholipid membrane. A low temperature will decline the rate of diffusion, as the particles will have less energy. The distance travelled will also affect diffusion rates. The longer the distance, the slower the diffusion is going to take place. The shorter the distance, the quicker the rate of diffusion 4. Gradients offer a pathway for molecules to go in and out of the cell.Many molecules are to big to fit through the semipermeable phosph olipid membrane and these gradients allow these large molecules to be able to cross through the cell. 5. Most cells are small because diffusion can take place at a quicker rate. The convolutions allow for more space to be able to be used in order to get molecules across the membrane. These small cells allow for materials to quickly be able to reach the cell membrane and get in or out of the cell, without having to make a long journey from an inside part of the cell. . Water will move out of the cell. The high water potential means there is little solute in the cell and more in the outside environment. In order to balance these concentrations, water moves out of the cell and creates equilibrium with the environment. 7. If saltwater is applied to a plant, the plant would shrivel up and die. This is a result of the water moving out of the cells in order to try to balance the concentration of solute compared to inside the cell.The water movement out of the cell would cause the cell to s hrink and the lack of water would eventually cause the plant to die. 8. A plant can control its turgor pressure through its central vacuole and cell wall. If a great amount of water is inside the cell, the central vacuole will take in some of the water to take some of the pressure of the cell wall. The cell wall can also eliminate water from making its way into the cell. The would cause the cell to keep expanding, but slowly eliminate its excess water.

China & Art Essay

China is probably the most influential and powerful civilization in Asia and is a good source of a very rich cultural and artistic heritage. In its early centuries, Buddhism, as the major religion of China has had a great influence in the country’s artistic imagery. Other art forms that thrived during this period were painting and calligraphy. It is also during this early time periods that China invented one of its greatest contributions to art and to the world – paper. Very early in during this period, the Chinese made what they called the mingqi. These are sculpted figures of soldiers, attendants, entertainers, and also of usual objects that people need and use such as houses, wells, stoves, and more. This is in part of their belief that even after death they would still need those things and continue living their usual routines as when they were still alive. Some of the early proofs of Buddhism in China were the carvings of Buddhist Images on the cliffs at Kungwangshan in Jiangsu Province. These images were dated back to around the 2nd century. At around 100 A. D. the Chinese had started working on developing paper. Rag paper (probably the first forms of paper) that was found was dated to as early as the 2nd century B. C. The first hemp paper however that had writings on it were dated to around 109 A. D. Cai Lun was one of those people who helped developed the method for mass-producing paper made from tree bark, hemp and linen. It was by the 3rd century that paper had been widely used in China. China also has their share of Ceramics. Ceramic products that hailed from the provinces of Zhejiang and Jiangsu are most admired. These provinces also had reputation in the creation of burial urns shaped like animals. The period from 220 to 265 A. D. was the period of the Three Kingdoms. Known for its Chivalric and Romantic nature, it became the setting and inspiration of one of China’s favorite historical novel. Written by Luo Guanzhong entitled Sanguo zhi yanyi (Romance of the Three Kingdoms) was published during the 14th century. Towards the end of these first 5 centuries at 317 to 420 A. D. , the arts flourished even more in China particularly at Nanjing in Jiangsu Province. It was also the period of development of Chinese literature. Some important Chinese personalities that arose from that time were Wang Xizhi for calligraphy, Gu Kaizhi for figure painting, and Tao Qian (aka Tao Yuanming) for poetry. And at the 5th century Xie He wrote the Guhua pinlu (Classification of Ancient Painters). Being one of the most famous Chinese critics, he wrote this book stating six laws which he thinks are the good characteristics of a work of art and the person who created it. His ideas have been recognized and considered in Chinese painting ever since. Conclusion It is quite apparent that in the three East Asian Cultures that were discussed, it seems that the Chinese really had a lot to contribute in terms of creating art and understanding art during the ancient times. And these contributions and ideas are still apparent even to the present day. Let us not fail to consider that other Asian cultures also had their own influences and contributions to , Asia and the World but China probably just had the most influential ones because they were probably the first in doing and developing many things also considering how big and powerful the Chinese civilization is. In looking for a commonality, it seemed that all three had their share of ceramic and pottery craft. Naturally, they did not yet have plastic back then and they were still quite new to metals which was why clay would be the main material they would likely use in creating things. They also had a different use for some pottery; they used some urns as sort of coffins in which they placed their dead. In understanding today’s culture, it would be good to look back and understand the ancient forms of art that had a great role in the development of a culture and how it influences other surrounding cultures up to the present days.

China’s Threat to the United States Economy

For the last twenty eight years, China has been quickly growing into one of the largest economies in the world. China has accomplished this feat, in part, by radically changing their policies on trade and free market interactions with other countries. During this process, China has bought approximately one hundred trillion dollars of United States debt in the form of Treasury bills, notes, bonds, and Inflation Protected Securities (Amadeo). This debt has given China leverage against the United States which has enabled China to keep the value of the United States dollar high, while keeping the value of the Chinese yuan low. As the inflation of the dollar continues to negatively affect the United States economy, China has become an economic superpower. Recently, concern has risen that China is a threat to the economy of the United States. China has become a perceived threat to the United States economy because of the increasing trade deficit between the two countries, the ability to undercut production costs of similar products produced in the United States, and the amount of leverage that China has over the United States due to the amount of money that has been lent by the Communist nation. Trade deficits between countries are caused when a country imports more goods from one country than they export to that same country. In the case of the United States and China, there is approximately a two hundred and twenty five billion dollar trade deficit (Prassad). The United States imports nearly three hundred and thirty five billion dollars worth of goods and services from China, while exporting only a little more than eighty billion dollars worth of goods and services to the growing economic power (CRS). The disparity in trade between the two countries results in a flooding of Chinese made products that force their United States competitors to lower production costs. In many cases, lowering production cost of domestic products results in either the closing of these businesses or the outsourcing of jobs. Both of these cause the loss of jobs in the United States. One of the reasons that the United States has been unable to lessen the trade deficit is China’s ability to undercut production costs of similar products made in the United States (Elwell 27) China’s overall cost of living is much lower than their United States counterparts (Amadeo). Therefore, they are able to produce goods and hire labor at a much lower price. One of the main reasons for this economic statistic is China’s population. It is nearly three times that of the United States, giving China a much larger work force to produce electronics, automobiles, and clothing at a fraction of the United States production cost (CIA). Not only does this negatively affect employment in the United States, but it also impacts their ability to compete on the global market. Industries that involve manufacturing, such as automobiles, computers, and electronics have decreased by thirty four percent since 1998 (Prasad). This has a negative effect on the amount of goods that the United States can export. Finally, China has gained a certain amount of leverage affecting the United States economic policies, due in part, to the amount of money that China has loaned the United States. Starting in the early 1980’s, every time the value of the dollar would drop, China would buy Treasury bills, notes, bonds, and Inflation Protected Securities to keep the dollar stable in value (Elwell 36). After nearly thirty years of this practice, the United States has come to depend on Chinese loans to maintain its currency value and China has come to own a majority of United States debt. This imbalance of debt has created a number of different scenarios that could bring about potential political and economic problems for the United States. China could theoretically cash in their treasuries and bonds tomorrow, which would cause the United States dollar to suffer massive inflation. While this scenario is not necessarily in China’s best interest right now, the possibility should concern the United States government. Instead, China could use their debt leverage to impact foreign trade policies and more importantly domestic political policies that budget how the United States spends its tax dollars (Elwell 22). China has become a perceived threat to the U. S. economy because of the increasing trade deficit between the two countries, their ability to undercut production costs of similar products produced in the United States, and the amount of leverage that China has over the United States due to amount of money that has been lent by China. Although the United States has taken steps to close the trade deficit, such as convincing China to raise prices on their exports, there is still a considerable gap (Prasad). The United States government continues to print money that they simply can’t afford, therefore, relying even more heavily on China sustaining the value of their currency. Unless the United States is able to close the trade deficit and regain control of our economic flexibility, the problems caused by foreign countries owning our debt will remain eminent.

The Methodology of Risk Decreasing and Fraud Operations Avoiding with Essay

The Methodology of Risk Decreasing and Fraud Operations Avoiding with Payment Cards of International Payment Systems - Essay Example As the discussion stresses the great quantity of these methods gives us an opportunity to choose the most suitable for each specific task, for each kind of database. This paper declares that systems analysis of multiple risks is used when we have no considerable database of certainly fraud operations, which represents different fraud kinds. The idea of using this methodology lied in developing of system classification by degree and level of risk and situation recognition of given classification. Alaric, a company, which specializes on banking systems, insists that fractal systems of fraud prevention, based on adjusted rules with using Bayes logic, are more effective then neuronets. But the high result production of there systems can be reached only after 4 months for banks with great quantity of emitted cards and high branched acquirer system. The neuronet can help to create a mechanism of operation stream evaluation, which will be based on special rules. Firstly, these rules are defined by experts, later changed and corrected with system. This function is necessary system component, as the fraud methods are changed as times goes by, and detectin g them mechanically, we’ll miss more refined and, surely, more detrimental for a bank. The second task is trivial enough. For topology identification can be used next algorithms of local optimization with calculation of partial derivatives of first order; local optimization with calculation of partial derivatives of first and second orders.

Happy Family Life Essay Example | Topics and Well Written Essays - 1000 words

Happy Family Life - Essay Example One simple rule that I have observed to be the most effective is when families eat dinner together. I remember several outdated TV commercials that portray a happy family on the dinner table while eating. The father would often come home from work tired and weary while the mother would burst out of the kitchen door and upon seeing off her husband, would gaily call â€Å"Kids, your father’s here!† The scene cuts then to the mother serving the dish she prepared for her family, to which her husband and children give a beaming look to each other before deciding to dig in and eat. The cutscene is particularly critical and it can be interpreted as the time to cook dinner for the mother is but just a few moments because she loves what she is doing. It is the smile that she sees in her husband and children’s faces that make it all worthwhile and thus the emphasis of the commercial is on the eager faces of the people she loves who are bound to get fed. Commercials like th ese are still successful in getting their point across millions of families worldwide and they are as attractive today as they were four decades ago. I recently went out with a girlfriend to the mall and when it was about past eleven, she was already seeming impatient and anxious, always checking her watch and her mobile. I never knew her to be a stickler for a time but about a quarter before twelve, she promptly asked if we could go home already as she is concerned that her family might get worried about her. I, of course, conceded to her wish and she verbally thanked me and gave me a hug. Later on, she would reveal to me the reason why she acted the way she did. She recalled that every evening at about eight o’clock, her parents would let her and her sister sit in the dining room and eat dinner. While eating, her parents would casually ask her and her sister how was school or how was their day in general.
