IT - Research Paper Example However, every system has its own advantages and disadvantages. Certain components easily get corrupted due to many reasons like improper handling and heat. Therefore, the factors causing damage must be carefully analyzed and techniques to reduce and to protect the data must be adopted. Role of Information Technology Information Technology plays a key role globally. It deals with computing technology, such as the internet, software, hardware or networking system. In other words, it is the tool of managing information using different software and hardware devices (Agarwal & Prasad, 2012). At present, information technology is used in varied sectors like medical and health, education and widely in corporate sectors. Information technology has become an inseparable part of private as well as public sector institutions. Consequently, the risk of media failure and data losses has been a serious matter of concern. Thus, creating the needs for reliable backup media to avoid data losses is q uite imperative (Chau & Hu, 2001). Backup Media Backup is usually an activity of copying databases in order to preserve that database in case a system failure takes place. Backup is a routine operation for the IT users. Backup prevents the users when catastrophe occurs in the system. The file when retrieved back to the system, it is called restoring. Various types of physical backup media are used to backup files, such as Optical DVD media, Internal Hard Disk, External Hard Disk and Flash memory (Hagen & Bieringer, 2001). Optical DVD Media Optical media comprises recordable/rewritable as well as dual layer formats DVD and CD disks. Optical Disc Drives use electromagnetic or laser light waves for reading and writing data. These devices are reasonably cost effective media to store small amount of data. In present times, nearly each and every personal computer comes with DVD or CD burners or writers. Data can be written and stored easily in a few minutes. Data can be stored in the form of documents, audio, video or in digital form. DVD rewritable permits the user to write discs and then erase and rewrite. DVD recordable provides permanent record for the data copied. Optical discs do not provide enough data storage space when compared to other media storages. Optical disks are not suitable for full system backup as it does not have sufficient capacity to store data .It needs certain special drives to write or read. Data stored in optical media gets destroyed, if it is scratched or exposed to heat. Thus, long-term reliability of optical DVD media cannot be assured (Hagen & Bieringer, 2001). Internal Hard Disk or A Second Hard Disk, Mounted Internally Internal Hard Disk is used for storing and retrieving digital information in the computer system. The hard disk may result in failure in many ways and cause loss of data either partly or totally. Internal hard disks are within the computer system and are easily available. Moving of files in case of internal hard disk i s easy and fast. The benefit of using internal hard disk is that its cost is low and the data transfer is easy. Data can be kept stored in the internal hard disk for considerable amount of time in various types of data format. It is highly vulnerable to virus attacks and malware. Trojans and power loss can cause data corruption and in such circumstances it

The Current Scenario And Its Causes Economics Essay

The Current Scenario And Its Causes Economics Essay INTRODUCTION: The current picture of the economic and financial state has caused a huge literature study evaluating its origin and how to respond with the pertinent strategy. Before going in depth let us discuss about general financial crisis [1] ( Charles,P et al 2005) . The situation can be termed as an economic crisis when a financial institution or an asset lose a large part of its value. It takes many factors into account when defining a global recession, but the International Monetary Fund  (IMF) states that general recession can be declared when the worldwide economic growth is 3 percent or less than that [12] (Rogoff,K.2002). FINANCIAL CRISIS- AN OVERVIEW: Financial crisis occurs when there is a sudden drop in market after a steady growth. It can be said that, it is the harbinger for the decline of market. Due to the volatility of the market and economic growth, this becomes the crux of the financial crisis. Stocks and real estate properties will reach the rock bottom after a period of growth. When the investors predict the market and invests in any sector, due to the market instability, the demand of that investment may decrease and their value of the estimation substantially diminishes. This trend follows a period and significantly investors huge investment does not return the expected revenue and this in turn affects their loan payment. They abruptly stop further investments and they begin to sell assets. [2] ( Aiginger,K. 2009) This trend persists in individuals private income too, they also follow the same practice by selling their assets and luxury objects. Over-optimistic companies and such individuals are the main cause for the crisis during the preceding economic growth epoch. They lean to believe that the general market growth will persists forever without any suspension. This optimism makes everyone to borrow colossal quantity of principal and invest them in homes, luxury objects and expansion of their business. Another cause are executives in banking companies tempted to lend out as much money as possible to the borrowers, regardless of the consequences for the bank and the borrowers, because this behavior gives the executives an enormous short term personal gain. When the supply decreased, the demand too got reduced. Hinder all the financial institution which lends out more money to the borrowers who pays back when they are comfortable [7]( carmassi et al, 2009). The government should interfere and has to lay proper regulations to set clear criteria that must be satisfied when the money lending process is done. Employment contrac ts for the bank executives should be forbidden by the bank which rewards them directly for the amount of mortgages they establish. When did it happen? The global financial crisis hit when there is a blooming economic trend persists. It happened in number of occasions, but the Great depression (1930) and the current financial crisis (2007-2010) are the core calamities which collapsed the global economy. [1] ( Charles,P et al 2005) THE CURRENT SCENARIO AND ITS CAUSES: The current financial crisis period started during 2007. It is the worst economic meltdown since the Great depression. The collapse of the US sub-prime mortgage market and the housing boom turnaround had a ripple effect around the world. Some financial goods and tools have become so difficult and abnormal, and things start to disentangle. The trust in the whole system started to fail. The origin of this present state is due to the extravagant lending of money by banks which permitted various groups to buy expensive assets that they could not afford. This was welcomed and encouraged by the politicians and was cleverly sold by the middle men. This created the trigger for the current scenario [9] ( Cooper,G. 2008) .The survival of excessive land use regulation which helped to drive up the prices. Innovations and internationalization are also cause for the regulation failure. Oligopoly structures in the agencies, insufficient regulation followed in the market, neglected cumulative system ic risks are the additional grounds involved in this trigger. Heterogeneity of profits across businesses, novel forms of equity standards, leveraging of banks, the firms and consumers are the factors which caused misinterpretation that the expected returns will be high. Bubbles in currency, oil and food shortages, short-term view on profits, inappropriate accounting rules and analysts reports, shortages of raw materials, energy deficit and unequal income and wealth distribution are the other aggravating factors which influenced the crisis [7]( carmassi et al, 2009). Consequently the demand decreased as the supply increased. This forms the nucleus of the present crisis. EFFECTS: As a result of this, unemployment increases and companies lay-off the employers in order to muddle through this recession, many banks filed bankruptcy and shortage of food supply too had its effects. The Gross domestic product (GDP) of the world declined for the first time since the Great depression of 1930. World economy growth dropped from 5% in 2007 to 3 % in 2008. USA and Europe economies already shrank during 2008 last quarter and those GDP from 2% to 4% [2] ( Aiginger,K. 2009). During the first quarter of 2009 production and orders declined when compared to the previous years. In order to compensate the cutback in the stipulated private sector caused by the crisis, the government passed large fiscal stimulus. During 2008-2009 alone US implemented two stimulus packages, totaling nearly $1 trillion [3] [2] ( Aiginger,K. 2009). The government has also bailed out many organizations due to large financial obligations. About 70% of GDP growth attained in the euro area and 40% of the same in the US due to the financial sector leverage [7]( carmassi et al, 2009). This is the key issues for the prevalent pressure in the European banking system. United States may be precursor of this current scenario, but the fragility persists in the European financial sector caused them badly and exposed to losses from US assets. An additional feature that made Europe more exposed to the crisis situation like the US is asset price bubble [7]( carmassi et al, 2009). Europe experienced the same real estate price bubble. During 2006-2007 house prices are less in US when compared to Europe, this is the key distinction involving the United States and the Europe [7]( carmassi et al, 2009). The banks in United States and Europe had excessive leverage and also the renovated maturity which are mistakenly manipulated by the regulatory system and allowed by the monetary policy. AGE WAVE THEORY: The additional cause for this economic slowdown was given by Ken Dychtwald, Ph.D in his Age wave theory [4] (Dychtwald, Ken, 1989). According to him, the persons who were born during 1947 to 1966 are called as baby boomers. According to the statistics the economic trend suitably followed as the baby boomers grow. Baby care books sales recorded a high during those initial years. Baby foods were consumed more during 1950s. The toy industry sales also reached record growth as the children grows. When they reached the teenage soft drinks sales and movie tickets sales reached the maximum. When the boomers enter the workforce during 1970s there was a record growth of 29%. Mini vans and SUVs dominated the automobile industry during 1980s and 1990s as the baby boomers started to raise their families. During 2007-2009 the workforce growth is just 12% due to the retirement of the baby boomers , and this may also be one of the reasons which kindled the crisis [5] (Dychtwald, Ken et al 2006). FUTURE REMEDIES: In order to tackle future recession, the UK government needs to follow some regulations. The economic policy should support the total demand by increasing the public demand or by providing inducements to encourage private expenditure [2] ( Aiginger,K. 2009). Monetary policy should be reintroduced to increase the money supply which has reduced interest rates. To improve the structure of taxation, fiscal policy is to be followed. It includes national and international stimulus packages. The European model to be followed [2] ( Aiginger,K. 2009), it includes strategic spending i.e., to invest in future technologies, education, research and development and green technology. Government and financiers should try to compress the scam and increase the capital requirements for banks .They also should follow the regulations and it would be compelled to hold sufficient funds to cover their normal operations. In order to reduce the jeopardy, the bank should bear all the risks and also increase their transparency, their accounting ethics are to be modified accordingly and also to be included in the asset definition. It is crucial that the current land rationing policies should wither as soon as possible. Capital requirements are to be set adequately so that it cannot be evaded by the mediators to raise liquidity [8] (Minsky, H. (2008) .The simple way of doing it is to set capital requirements with reference to total assets and no gimmicks allowed. The main cause for the delude information for investors and obstinate incentives are the assets with maximum risk. [6] (Gros, D. (2009). These assets should be scrapped to maintain the economy. The government should provide guarantees by affording small pensions and loans and also it should fight poverty by employment. The youth unemployment problem can be tackled by training and also making informal jobs more professional. By increasing the choices the supply and demand stability can be maintained. These aforementioned strategies are to be followed by the UK government in order to maintain the stability and also to prevent the arrival of the current scenario [10] (Greenspan ,A. 2009). CONCLUSION: Brian Cowen, the former finance minister says that, If I am right, the next financial crisis, when it comes, stands to make the last two years look like a warm up [11]. So the optimism and complacency natures should be discarded and follow the policies and also the remedies as mentioned above to restore the trust and balance in the system.

The History of Computers :: Computers Technology Essays

The History of Computers Thousands of years ago calculations were done using people’s fingers and pebbles that were found just lying around. Technology has transformed so much that today the most complicated computations are done within seconds. Human dependency on computers is increasing everyday. Just think how hard it would be to live a week without a computer. We owe the advancements of computers and other such electronic devices to the intelligence of men of the past. The history of the computer dates back all the way to the prehistoric times. The first step towards the development of the computer, the abacus, was developed in Babylonia in 500 B.C. and functioned as a simple counting tool. It was not until thousands of years later that the first calculator was produced. In 1623, the first mechanical calculator was invented by Wilhelm Schikard, the â€Å"Calculating Clock,† as it was often referred to as, â€Å"performed it’s operations by wheels, which worked similar to a car’s odometer† (Evolution, 1). Still, there had not yet been anything invented that could even be characterized as a computer. Finally, in 1625 the slide rule was created becoming â€Å"the first analog computer of the modern ages† (Evolution, 1). One of the biggest breakthroughs came from by Blaise Pascal in 1642, who invented a mechanical calculator whose main function was adding and subtracting numbers. Years later, Gottfr ied Leibnez improved Pascal’s model by allowing it to also perform such operations as multiplying, dividing, taking the square root. Technology continued to prosper in the computer world into the nineteenth century. A major figure during this time is Charles Babbage, designed the idea of the Difference Engine in the year 1820. It was a calculating machine designed to tabulate the results of mathematical functions (Evans, 38). Babbage, however, never completed this invention because he came up with a newer creation in which he named the Analytical Engine. This computer was expected to solve â€Å"any mathematical problem† (Triumph, 2). It relied on the punch card input. The machine was never actually finished by Babbage, and today Herman Hollerith has been credited with the fabrication of the punch card tabulating machine.

The Effects Of Reciprocal Teaching On English Language Education Essay

This reappraisal of the literature is separated into subdivisions get downing with mutual instruction and the current research. The surveies for mutual instruction are reviewed harmonizing to their research design ( e.g. , meta-analysis, group designs, qualitative designs, and single-subject designs ) . Part of this subdivision includes a reappraisal of the mutual instruction monitoring scheme as it relates to current surveies. Subsequently there is a sum-up of the unwritten linguistic communication development in English Language Learners ( ELLs ) . With a turning figure of immigrants from assorted states, Miami Dade County Public Schools ( M-DCPS ) is a runing pot of ELLs. M-DCPS is besides the second-largest minority public school territory in the state. These pupils are expected to execute at the same degrees as their equals on the Standardized Achievement Test, Tenth Edition ( SAT-10 ) regardless of their appreciation of the English linguistic communication. With the current move into answerability and pupil accomplishment, instructors are obliged to happen schemes to help the ELLs in increasing non merely vocabulary, but besides reading comprehension. ELL pupils need to understand the reading strategies non merely to go through the SAT-10 and progress to the following class degree but besides to construe text in the existent universe. In order for pupils to efficaciously utilize the reading schemes, they must be actively engaged in the activities that are represented to them. The instructor must supply a huge sum of chances across all capable affair and convey in illustration from their day-to-day lives every bit good. If the pupil continues to pull strings the assorted passages/text, so their comprehension accomplishments will increase and in bend will accomplish higher tonss in the SAT-10.Reciprocal TeachingResearch workers in a figure of surveies have systematically found that mutual instruction is an effectual manner to increase pupil comprehension. Relatively small is known about the issues of how multiple schemes can, and should, be combined in comprehension direction ( Brunstein & A ; Kieschke, Sporer 2009 ) . Reciprocal in struction ( RT ) is an instructional process developed by Palincsar and Brown ( 1984 ) to better pupils ‘ text comprehension accomplishments through scaffold direction of four comprehension-fostering and comprehension-monitoring schemes ( Palincsar & A ; Brown, 1984 ; Palincsar, David, & A ; Brown, 1989 ; Rosenshine & A ; Meister, 1994 ) , that is, ( a ) bring forthing one ‘s ain inquiries, ( B ) sum uping parts of the text, ( degree Celsius ) clear uping word significances and confounding text transitions, and ( vitamin D ) foretelling what might come next in the text ( Brunstein & A ; Kieschke, Sporer 2009 ) . The instructor could so supply counsel and feedback at the appropriate degree for each pupil. Theories of comprehension suggests that active acquisition from text must affect a flexible repertory of comprehension-fostering and monitoring activities ( Alfassi, 1998 ) . Explicit direction in comprehension-enhancing activities appears particularly important for the novice reader and the academically delayed pupil ( Alfassi, 1998 ) .Meta-AnalysisIn order to look into the effectivity of mutual learning two meta-analyses have been conducted. Meister and Rosenshine ( 1994 ) provided the first analysis of the survey. After placing 16 published and unpolished surveies related to mutual instruction, they concluded that teacher-made appraisals had a greater consequence on reading comprehension instead than standardised trial. In general, Meister and Rosenshine and ( 1994 ) found that when the four schemes ( i.e. , oppugning, sum uping, clear uping, and foretelling ) were explicitly taught before prosecuting in the mutual instruction processs pupils ‘ comprehension abilities increased more than when the schemes were taught as the mutual instruction intercession was in procedure. In an unpublished thesis by Galloway ( 2003 ) , an extended reappraisal of the current literature on mutual instruction was conducted utilizing traditional meta-analysis. The research worker found moderate consequence sizes for intercessions utilizing mutual instruction. The important differences between teacher-made trials and norm-referenced trials found by Meister and Rosenshine ( 1994 ) were non found by Galloway ( 2003 ) . Galloway concluded there still is a demand to document in the literature the execution of the mutual instruction process. Both of the meta-analytic surveies described provide support for the effectivity of mutual instruction. Sample size and the fidelity to which the mutual instruction intercession was implemented remain a restriction.Group DesignsLysynchuk, Pressly, and Vye ( 1990 ) studied how mutual instruction improves the reading comprehension public presentation of hapless readers. In this survey, 72 four and rate seven pupils in Canada participated in 1 3 Sessionss of mutual learning reading intercession reading direction. Of the 72 pupils, 36 were assigned to the mutual instruction intercession, while the others worked in little groups, with the instructor offering aid if needed in decrypting and transition apprehension. Thirteen Sessionss were administered to both groups, with day-to-day dependent steps being taken ( i.e. , reciting and inquiries ) , every bit good as pre and station standardised reading steps. For both informal and formal appraisals, the reading comprehension of the experimental group of hapless decipherers was higher than the control group of hapless decipherers. No betterments were seen on vocabulary acquisition and care in either group. Klinger and Vaughn ( 1996 ) used mutual instruction as an intercession for hapless decipherers with larning disablements ( LD ) , but who were besides ELL at the in-between school degree. This survey concluded that mutual learning intercession appeared to better the reading comprehension of pupils with LD/ELL and supported mold and societal interaction as agencies to larning as proposed by Vygotsky ( Schunk, 2004 ) .Qualitative DesignsThe usage of qualitative research methods lend themselves good in the probe of jobs where engagement, observation, and enquiry of intending are of involvement ( Shank, 2006 ) . In a survey conducted by Hacker and Tenent ( 2002 ) instructors constructed their cognition of mutual instruction ( based on Hashey & A ; Jimmy conorss, 2003 ) as they implemented the intercession. The survey lasted 3 old ages and 17 instructors from two simple schools were followed. Data was collected based on patterns and alterations of mutual instruction in order for them to d evelop a theory on how to implement the intercession efficaciously in the schoolroom. The three elements of mutual instruction that were examined: scheme usage, profusion of duologue, and scaffold direction. The chief issue the instructors encountered with the pupils was in duologue in which they felt it was superficial and non rich ; this determination was besides supported by Whitehead ‘s ( 2002 ) probe of guided reading intercession. Hashey and Connors ( 2003 ) besides suggest that pupils benefit from mutual learning beginning in the 3rd class because of their experience with decrypting accomplishments.Single-Subject DesignsPalincsar, David, and Brown ( 1989 ) have suggested that mutual instruction may be more good as a little group intercession. In the initial mutual instruction survey, Palincsar and Brown ( 1984 ) employed a individual capable research design to look into the effects of mutual instruction with a little group of pupils. To day of the month several research workers have utilized individual capable designs to mensurate the effects of mutual learning with little groups of pupils in applied scenes.The Reading ProcedureCrowder and Wagner ( 1992 ) suggest reading may be a â€Å" fuzzed construct † ( p. 3 ) to understand ; it is a complex procedure ( Sternberg, 2003 ) , A simpler position of the reading procedure was explained by Hoover and Gough ( 1990 ) . The research workers suggested that the reading procedure consisted of two constituents: decryption and comprehension. To them, decrypting encompasses phonemic consciousness, phonics, and reading eloquence, while comprehension and vocabulary are thought of as one constituent. The simple construct of decrypting and comprehension was elaborated on by LaBerge and Samuels ( 1974 ) . From the position of cognitive psychological science, they proposed a theory of automaticity, which explained decrypting as a combination of reading velocity and truth. This eloquence in decrypting allows for cognitive resources to treat information expeditiously make intending from text ( Hashey & A ; Jimmy conorss, 2003 ) . Therefore, fluid readers have the ability and attending to grok what they read. Conversely, hapless decipherers, who lack eloquence, will utilize their available cognitive resources to decrypt alternatively of utilizing those resources to grok text to the full ( LaBerge & A ; Samuels, 1974 ) ; this deficiency of eloquence outputs superficial comprehension and spreads in apprehension.English Language LearnersThere is limited research conducted on the unwritten linguistic communication development in English Language Learners ( ELLs ) , such as vocabulary, grammatical signifier, and matter-of-fact forms. Therefore, restricting the apprehension of specific facets of ELLs unwritten linguistic communication development and, therefore small empirical footing for be aftering educational intercessions ( Genesse, Lindholm-Leary, Saunders & A ; Christian, 2006 ) . Latino pupils as a whole, including English proficient kids in the 2nd coevals and beyond, score significantly lower in reading than other pupils. However, the chance of geting an unknown word by the way through reading is merely approximately 15 % ( Swanborn & A ; de Glopper, 1999 ) . These pupils frequently exhibit more jobs with reading comprehension than make fluid talkers of English of comparable ability, because of differences in background cognition relevant to what is read in school and limited English linguistic communication proficiency ( Klingner & A ; Vaughn, 1996 ) . There are besides assorted positions on the benefits of mutual instruction. Many surveies suggests that ELLs can profit from mutual instruction because of improve comprehension for pupils who can decrypt but have trouble groking text ( Klingner & A ; Vaughn, 1996 ) and others recommend that vocabulary direction should take topographic point in order to increase pupil comprehension ( Genesse, Lindholm-Leary, Saunders & A ; Christian, 2006 ) . Prior mutual instruction research has examined the effects of teacher-facilitated scheme direction without analyzing how pupils apply schemes when the instructor is non present ( Klingner & A ; Vaughn, 1996 ) . This survey conducted by Klingner and Vaughn ( 1996 ) proved that that initial reading ability and unwritten linguistic communication proficiency seemed related to additions in comprehension, that a greater scope of pupils benefited from scheme direction than would hold been predicted on the footing of old research, and that pupils in both groups continued to demo betterment in comprehension when provided minimum grownup support. For those grounds, it is critical to understand the relationship of mutual instruction among ELLs. This will let instructors to outdo find the most effectual reading scheme to accomplish acquisition additions in reading comprehension. These patterns include expressed direction in nucleus reading competences after control for undertaking trouble through systematic staging, learning pupils separately or in little groups, patterning and learning schemes, learning when and where to use schemes, ongoing and systematic feedback, and ongoing advancement monitoring ( Miester & A ; Rosenshine, 1994 ) .
