Life with No Possibility of Parole free essay sample

An examination of the life sentence and how parole is allocated. An in-depth look at prison sentencing and allocation of parole. The author argues that life sentencing in the U.S. court system is unfair and that majority of life term prisoners are first time prisoners that receive life sentence due to their involvement with drugs. In effect prisons become full and more dangerous criminals are given parole as they dont sit for life sentences. The author further discusses the effects of this on tax-payers and on society in general. Imagine receiving a 25-year prison sentence with no possible chance of parole. There is not even a way the sentence can be reduced from the start. For repeat offenders, this is becoming common in the American criminal justice system. Now imagine it is the first offence, and yet there is still a 25-year to life sentence imposed. This situation is quite common in many states, i.

The question must be asked: Are mandatory minimum sentences in drug offences truly just in todays society? Sentences like these are unfair to many of those convicted under them. Mandatory minimum sentences have been filling American prison systems with first-time, non-violent offenders, the majority of which are drug offenders. Since these sentences cannot be reduced, room has to be made for all of the incoming prisoners. In order for the room to be made, violent offenders are usually released early. Not only are these sentences unfair to the offenders, but also because of the extreme sentences, they are costly to the American taxpayer.

Computer Viruses Essays (1326 words) - Computer Viruses,

Computer Viruses Almost every End-user in the world has heard of computer viruses and/or has had one at one point in time. Don't worry if you haven't heard about them, you won't find it in your bloodstream. Unfortunately you may find one in your computer memory or disk storage. ? Some may be as benign as the common cold and others as deadly to your hard drive as the Ebola virus ?. - 1 -What is a Computer Virus? ~ Usually defined as ? a malicious code of computer programming? it is actually just another software, only written with not so noble intentions. ~ A computer virus is designed to install, reproduce itself and cause damage to computer files and data without the users knowledge or permission. ~ A computer virus can only survive and attack in computer memory, which is usually RAM and disk storage. ~ You will not find a computer virus in your monitor or keyboard. How will the virus invade your computer? ~ All viruses enter the system through two main points. ~ Disk drive ~ Network adapter cards. ~ Disk drives may be any type (hard, floppy, CD and whatever you have). This makes anything you insert in your drive a possible source of infection. ~ The network adapter card is most likely your connection to the Internet. Viruses enter here most likely disguised as e-mail attachments. These attachments are often program files and office documents containing macros. Besides e-mail attachments, there are certain WebPages that contain harmful programming codes that may transfer into your computer as virus or virus-like codes. How do viruses spread? ~ After entering the computer memory, A virus often immediately sets out to multiply and spread duplicate copies of itself across the main data storage device. It does this by copying itself into as many files as it can on the disk drive. Later when users transfer or copy these files to their friends and colleagues, the virus can gain entry to all of their systems. If the virus has come this far on its path, the user may have permanent damage to data and hardware. Such a level of infection only happens to two types of users, those who do not install good anti-virus programs and those who do not update their programs on a monthly basis. As a result newer viruses can actually use the anti-virus programs to infect an even greater number of files. Four main types of viruses ~ 1) Boot sector viruses are usually transmitted when an infected floppy disk is left in the drive and the system is rebooted. The virus is read from the infected boot sector of the floppy disk and written to the master boot record of the system's hard drive. The master boot sector is the first place your system reads from when booting up from the hard drive. Then whenever the computer is booted up, the virus will be loaded into the system's memory. 2) Program or file viruses are pieces of viral code that attach themselves to executable programs. Once the infected program is run, the virus is transferred to your system's memory and may replicate itself further. 3) Macro viruses are currently the most commonly found viruses. They infect files run by applications that use macro languages, like Microsoft Word or excel. The virus looks like a macro in the file, and when the file is opened, the virus can execute commands understood by the application's macro language. 4) Multipartite viruses have characteristics of both boot sector viruses and file viruses. They may start out in the boot sector and spread to the applications, or vice versa. While not technically viruses, other malicious programs like worms and Trojan horses usually get stuck in there too. A worm is a program that replicates itself but does not necessarily infect other programs. Just like in the Greek myth, Trojan horses contain a concealed surprise. A Trojan horse program lies hidden in another seemingly harmless piece of software until some condition triggers its awakening. Why are they called viruses? The term virus is more recent, and was first used in 1984 by Professor Fred Cohen to describe self-replicating programs. The earliest PC viruses came a bit later in 1986. The name is appropriate because like a biological virus, a computer virus is

DRC History essays

DRC History essays The DRC, has a turbulent political history racked with war and colonization. Though much of the DRCs history is still unknown, the most clear information is on its political past, Belgian Congo to Zaire. The history, includes various uprisings, and slave trading. Henry Stanley, an English explorer, explored the Congo from 1874 to 1877. Stanley explored most of the Congo river, a 1,600 mile journey. Stanley wanted the British government to colonize the area, but the government refused to do so. Soon after his journey, king Looped II of Belgium asked Stanley to set up trading posts. Stanley also communicated with local tribal chiefs. The Congo Free State, was governed by Belgium, and officially recognized by the world as a nation in 1885. After nationalist riots in Lopoldville in 1959, elections were held. Patrice Lumumba, and his Congolese National Movement Party, claimed an outright victory. The riots and elections, were the result of years of Belgian misrule and abuse of the native Congolese. The Belgians, forced the Congolese to work the rubber tree fields to pay for high taxes. The Congolese were also not allowed to own land, and had fewer rights than the white colonists. The DRC was officially declared independent on June 30, 1960. The government again changed hands in 1965, when Kasavubu was elected prime minister. Joseph Mobutu, then secretary of the military, overthrew Kasavubu and installed himself as president. Mobutu brought stability to the country at first, but soon became corrupt. In 1971, he made a new constitution, and the country was renamed the Republic of Zaire. During this period city names were Africanized, Lopoldville became Kinshasa. Mobutu seized foreign companies, and nationalized them, distributing control among his close friends and supporters. Mobutu funneled his private wealth of four billion us dollars from the companies, and laundered money...

Windber Medical Center Essay Example | Topics and Well Written Essays - 750 words

Windber Medical Center - Essay Example Adherence to staff hierarchy and unquestioned physician authority were the norm. However, with the demise of the coal industry, Windber Medical Center lost its key clientele, influence and revenue dipped. To make matters worse Congress enacted the Balanced Budget Amendment Act that changed how reimbursements would be made to small, nonteaching and non-rural hospitals such as Windber. This meant that Windber would have to find a way to be more competitive in order to attract more patients, government funding and funding from other third parties. Diagnosis: What problems was Windber Medical Center facing? According to the report from Ernst and Young, Windber was not making enough money and it faced an imminent demise in five years’ time because of the changes in insurance reimbursements, changes in government reimbursements and heightened competition due to increased penetration of managed care products in the market. Furthermore, Windber was located in an area where the populat ion was migrating out of thus reducing the size of its market. However, the root cause of Windber’s problems was that it operated in an archaic system that saw patients as â€Å"disruptions† rather than as customers.... The new president charged with implementing the change made appointments to meet with each employee and members of the medical staff individually. This assessment method was effective because it enabled the president to understand the organization’s culture fully as well as its influence on each employee. A similar tactic with the medical staff was not successful, however out of its failure the president learnt about the hidden, informal power structure. He learnt that there were sixteen physicians who were the nucleus of power among the medical staff. Out of this assessment it was also noted that senior managers who believed in the power of physicians sided with them on every decision. Design: What is the desired state or goal? The ultimate aim of the change effort at Windber Medical Center was to make patient-centered care the organization’s premier priority. To support this goal the organization also committed to providing a loving, nurturing environment to patients and their families as well as to addressing all patient and patient family issues quickly and efficiently. Implementation: What interventions were employed to reach this goal? Four techniques were adopted by management to advance the change effort: training, rewards, dismissals, feedback sessions and media communications. Trainings were done through: (1) peer-to-peer where four employees from different departments were trained offsite and brought back to train their peers; (2) hiring of a management consultant; (3) taking head of departments on tours to learn new models of care; and (4) annual refresher courses. Rewards were given to employees caught caring and this motivated others to do the same. After three years nearly 10 percent of the workforce

Te Uku - wind farm project Essay Example | Topics and Well Written Essays - 2000 words

Te Uku - wind farm project - Essay Example Networks that constructed the 33kV transmission line with a length of 25 kilometers in order to distribute electricity generated by the 28 wind turbines of the wind farm. Overall, the wind farm has a capacity of 64.4 MW coming from 28 turbines, with an average of 2.3MW of power from each turbine (Discover Te Uku, 2014). The Te Uku Wind Farm project in Waikato is very efficient in terms of energy production in supplying the area which it is supposed to supply with electrical power. Moreover, when it comes to sustainability, the assessment of environmental effects shows that the wind farm has mostly a neutral relationship with its surrounding flora, fauna and earth. However, in terms of its earthworks, the Te Uku Wind Farm project somehow falls short of some of the requirements of the RMA. Nevertheless, the company’s continued existence proves otherwise. Lastly, the economic value of the wind farm is that it has somehow provided so many jobs to workers. The Resource Management Act, or RMA, is the specific national policy or the aspect of the law that explains the laws that govern the establishment, maintenance and operations of certain projects, firms and infrastructures in New Zealand. Specifically, when it comes to the operation of wind turbines, wind farms do not actually qualify as â€Å"rural industries† because the term â€Å"rural industries† excludes the generation of electricity (Resource Management Act, 2007). Therefore, wind farms are known as a â€Å"Discretionary Activity† and may not comply with some of the standards of Permitted Activity as specified by the law (Resource Management Act, 2007). Nevertheless, the continuous operation of the Te Uku Wind Farm up to this day implies that its requirements as a discretionary activity have been complied with. The earthworks plans for the project have also been considered questionable by virtue of the provisions of the Resource Management Act, but the fact that the wind farm operates until now somehow

Handwashing Practices among Health Workers

Handwashing Practices among Health Workers BACKGROUND Hand washing or hand hygiene is the process of cleaning ones hands with or without the use of water or another liquid, or with the use of soap for the purpose of removing soil, dirt, and/or microorganisms. Handwashing involves five simple and effective steps; Wet, Lather, Scrub, Rinse and Dry. Regular handwashing, particularly before and after certain activities, is one of the best ways to remove germs, avoid getting sick, and prevent the spread of germs to others. Its simple, its quick, and it can keep us all from getting infected (CDC, 2016). The provision of healthcare worldwide is always associated with a potential range of safety problems. Yet, despite advances in healthcare systems, patients remain vulnerable to unintentional harm in hospitals (Devnani et al. 2011; Mani et al. 2010). One of the most significant, current discussions in healthcare delivery in hospitals is healthcare associated infection (HAI), sometimes called hospital acquired infection (Mani et al. 2010; Momen Fernie 2010) or nosocomial infection, which is any infection that a person develops as a result of treatment in hospital (Minnaar 2008, 2). Nosocomial infection is a global public health problem with an estimated 1.5 million suffering consequences at any given time [WHO,2009] noted that at least 25% of all hospital infections in the developing world are nosocomially acquired. The hands of health care providers are major agents of infection transmission in hospitals leading to the campaign to improve hand hygiene, Clean Care is Safer Care [WHO, 2005]. Two types of hand colonizing flora are predominant in hand skins. These are the Resident flora that are not easily removed by the simple friction associated hand washing and the Transient microorganisms which are not usually hand colonizers but they are most likely associated with infection [ Grayson, 2009]. Various types of such microbes are found on patients, instruments and other items and are important in infection transmission  [Hubner, 2006]. Improper hand washing practices serve as means of infection transmission in hospital wards (Duckro, 2005). Hand hygiene was thought to be a key factor in reducing hospital acquired infection during the initial development of healthcare systems (Akyol 2007; Ott French 2009). The battle with HAI started when the Hungarian obstetrician, Semmelweis (1847), observed that puerperal fever was more common on a maternity ward, where physicians and medical students provided care to women in labour, than it was on the ward where midwives assisted deliveries. He noted that physicians and medical students were contaminating their hands while performing autopsies and later attending the examination of women without hand washing. Arguably, he was the first to recognise the importance of hand washing in controlling the transmission of infection (Akyol 2007; Meers et al. 1992; Trampuz Widmer 2004). Equally important was the work of Florence Nightingale during the Crimean war, when she called for basic public health in a military hospital in Scutari in 1854. PROBLEM STATEMENT Hospital acquired infections has resulted in many negative impacts on health workers, patients and families over the world (WHO2012). The working environment, health workers and patients are the main reservoirs of hospital acquired related infection (weber, 2013). The transmission of infection from patient to patient mainly occurs at the hands of health workers (Ellingson K, 2014). The hands of health professionals are contaminated during patient care on a daily bases despite wearing gloves (Kendal A, 2012). Handwashing is critical in the prevention of hospital acquired infections. It is a very simple procedure and work well in the prevention of diseases as people are the carriers of pathogenic microbes. The practice is however unacceptably low among health workers (Takahashi Turale 2010; Trampuz Widmer 2004). Hand hygiene compliance rates in different developed countries rarely exceed 50% (Mani et al. 2010; Maxfield Dull 2011; Ott French 2009). For instance, figures show that in the USA it is 50%, in Switzerland 42% and in the UK 32% (Takahashi Turale 2010). Hence, poor compliance has resulted in high morbidity and mortality. In the USA, there are between 1.7 and 2 million people who contract HAI and 88 to 99 thousand deaths are attributed to HAI annually. Furthermore, HAI affects nearly 10% of hospitalised patients and presents major challenges in healthcare facilities. Consequently, annual medical expenses have increased in the USA to approximately $ 4.5 billion (Maxfield Dull 2011; Smith Lokhorst 2009; Trampuz Widmer 2004). Hand hygiene practice among HCWs is considered to be the single most clinical and cost effective measure to prevent HAI, a view recognised internationally (Momen Fernie 2010; Ott French 2009; Takahashi Turale 2010).The World Health Organisation (WHO) strongly emphasise the essential need for hand hygiene during healthcare delivery, to avoid possible infection and subsequent complications; hence, the Clean Care is Safe Care programme, launched by WHO in 2005 as part of the First Global Patient Safety Challenge. This programme offers new guidelines on hand hygiene training, observation and performance reporting in healthcare settings. Out of every 100 hospitalized patients, at least 7 in high-income and 10 in low-/middle-income countries will acquire a healthcare-associated infection. Among critically ill and vulnerable patients in intensive care units, that figure rises to around 30 per 100 (who,2014). Factors that contribute to poor hand washing compliance include absence of hand washing sinks, time required to perform hand hygiene, patients condition, effect of hand-hygiene products on the skin and inadequate knowledge of the guidelines(Larson and Kretzer, 1995; Simmons et al., 1999;Meengs et al., 1994; Doebbeling et al., 1992; Voss and Widmer, 1997). PURPOSE OF THE STUDY The purpose of this study is to determine the knowledge, attitude, and practices of healthworkers and also compare between healthworkers regarding their knowledge, attitude, and practices on hand washing. MAIN OBJECTIVE To determine hand washing practices among health workers in the Tamale West Hospital. SPECIFIC OBJECTIVES Assess the knowledge, practices and attitudes of healthworkers on handwashing Assess the differences across age groups, gender and experience regarding KAP of handwashing Compare between healthworkers regarding KAP of handwashing Assess the availability of resources for handwashing RESEARCH QUESTIONS What is the knowledge, practices and attitudes of healthworkers concerning handwashing? Are there differences across age groups, gender and experience regarding KAP of handwashing? Can KAP between healthworkers regarding handwashing be compared? Are there available resources for handwashing? SIGNIFICANCE OF THE STUDY Hand washing is considered the most important single and simple practice for preventing hospital acquired infection. An intricate problem may be caused by a number of factors if there is failure to practice effective hand washing. Understanding the factors that influence this behavior is key to change the behavior of poor effective hand washing practices. More studies are needed to identify, which of the factors contribute significantly to the problem of poor compliance with hand washing recommendation. OPERATIONAL DEFINITION OF TERMS Hand washing Hand washing is the process of cleaning ones hands with or without the use of water or another liquid, or with the use of soap for the purpose of removing soil, dirt, and/or microorganisms. Health care workers Professional personnel working in clinical setting of a health facility Veronica buckets Buckets used to store water for washing of hands Nosocomial infection/hospital acquired infection are infections gotten from the hospital setting. LITERATURE REVIEW KNOWLEDGE, PRACTICES AND ATTITUDES OF HEALTHWORKERS ON HANDWASHING Hand hygiene practice among HCWs is considered to be the single most clinical and cost effective measure to prevent HAI, a view recognized globally. Despite the relative simplicity of this procedure, adherence to hand washing recommendations is unacceptably low, usually well below 50% (Ekwere Okafor, 2013). Most nosocomial infections are thought to be transmitted by the hands of health care workers. It has long been known that hand hygiene among health care workers plays a central role in preventing the transmission of infectious agents. Hand-washing (HW) is the most effectiveway of preventing the spread of infectious diseases But despite a Joint Commission requirementthat Centers for Disease Control and Prevention hand hygiene guidelines be implemented in hospitals, compliance among health care workers remains low The reasons for low compliance to hand hygiene have not been defined in developing countries probably due to limited studies on hand hygiene. Factors that contribute to n oncompliance to HW among health careworkers are: lack of awareness and knowledge among health care workers as regard the importance, techniques, methods and quality of hand hygiene (Abd El Aziz Bakr, 2009). Alex-Hart and Opara, (2011) study on hand washing revealed that, more than halve (55.4%) of the health workers lacked the knowledge of good hand washing technique as most believed it involved the use of soapy water in a basin. This may be due to the fact that running water is not readily available, so the use of soapy water in a basin may have been the available alternative. With its repeated use over time, most health workers may have come to perceive it as the ideal hand washing technique. The NMCS Code of Standards and Conduct requires nurses and midwifes to provide a highstandard of practical care all the time. Yet, the momentum for hand hygiene, some nurses are still presenting with low compliance because they perceive it as not their problem, that it is something to do with infection control staff and they have to deal with it . Furthermore, Nazarko (2009) indicates that nurses often fail to practise hand hygiene because they are busy and they feel hand hygiene takes up precious time. In addition, nurses often perceive that gloves can be used as an alternative to hand hygiene. They usually tend to remove the gloves without washing their hands or use the same gloves to deliver intended care to multiple patients. Even when they remove their gloves, only 20% of nurses actually clean their hands (Ott French 2009). According to Canham, (2011) nurses avoid hand hygiene because they are frightened that skin problems such as dermatitis could develop, especially with alcoh ol hand-rubs. DIFFERENCES ACROSS AGE GROUPS, GENDER AND EXPERIENCE REGARDING KAP OF HANDWASHING Nurses tend to wash their hands more often than doctors and among non-health care workers, females tend to wash their hands more often than males. This study examined the influence of gender on the hand washing rates of health care workers (HCWs). The null hypotheses were that, there would be no inter-gender difference in either hand washing rates in healthcare workers across professions, or within professional groups. Although increased compliance with hand washing protocols has been shown to decrease infection rates, hand washing compliance remains poor, particularly among some professional groups. Studies of hand washing frequency have recorded hand washing rates following patient contact ranging from 10.6% to 61%, and significant differences have long been noted in hand washing frequency between professional groups such as nurses and doctors. (Van de Mortel, 2001) Van de Mortel, (2001) studies again found out found that, registered nurses (RNs) washed their hands following patient contact significantly more often than doctors in the Intensive Care Unit (ICU). The RNs washed their hands 71% percent of the time, whilst junior and senior resident doctors (RMOs) washed their hands 50% of the time and specialists washed only 25% of the time. He postulated that, failure to wash hands may be a gender-related phenomenon. The proportion of female nurses is considerably higher than the proportion of female doctors. In the above study, 90% of the nurses were female; 45% of RMOs and 6% of specialists were female. (Van de Mortel, 2001). Several studies have examined, among other variables, the influence of gender on hand washing frequency in health care workers however; these studies arrived at conflicting conclusions. Van de Mortel, (2001) found that hand washing frequency in the emergency department was lower among female nurses, RMOs and specialists tha n among males within each of those groups, however, the sample size of the study was small (n = 13 nurses, 11 RMOs, and 11 specialists). In contrast, in an extensive study of hand washing practices in two countries, it revealed that female health care workers were washing their hands more frequently than males, regardless of occupational group. However, this study was based on self-reported practices collected by questionnaire, and a degree of bias may have been introduced due to the fact that non-responders may have exhibited different behavior than responders. There is also a tendency for people to overestimate socially desirable behavior when answering questionnaires. To illustrate the latter point, Van de Mortel, collected data on hand washing frequency among doctors, both by means of questionnaires and by covert observation. He found that doctors estimated that they washed their hands 73% of the time, but the data collected by covert observation showed the percentage of doctors washing their hands following patient contact was in fact only 10.8%. METHODOLOGY This chapter describes the study area, the study design, the study population and the sampling procedure as well as the recruitment of respondents and the data collection procedure. The data entry and analysis is also outlined in this chapter. RESEARCH DESIGN This study is a cross-sectional study method designed to assess the knowledge, attitude and practices of health workers in TTH towards handwashing. Including assessing the differences across age groups, gender and experience regarding knowledge, attitude and practices of handwashing, and also, compare between healthworkers regarding KAP of handwashing RESEARCH SETTING The study will be conducted at the Tamale Teaching Hospital (TTH). It is a foremost tertiary referral centre providing patient care to residents of Tamale and neighboring towns and cities. There are 30 wards in Tamale Teaching Hospital. There are 74 doctors and 655nurses at the hospital. Hand-washing facilities are located in all the wards and clinics in the hospitals. Each ward is provided with at least a Veronica bucket for hand washing, running tap water, soap (liquid or cake) and sometimes, a towel for hand drying. TARGET POPULATION This study targets the clinical staff of the Tamale Teaching Hospital with a total population of 729. There are 31 wards in Tamale Teaching Hospital SAMPLE, SAMPLE SIZE, AND SAMPLING TECHNIQUE The sample size is 360 respondents this was arrived at by the using Cochran formula. Sample Size = [z2 * p(1-p)] / e2 / 1 + [z2 * p(1-p)] / e2 * N] N = population size z = z-score e = margin of error p = standard of deviation N= 729 Z= 1.96 (using 95% confidence interval) E=0.05 P= 0.5 Sample size = [(1.96)2*0.5(1-0.5)]/0.052 / 1 + [1.962*0.5(1-0.5)]/0.052* N Sample size = 384.16/1.076 Sample size= 357 An extra 3 was added to make it a total of 360 respondents. There are 30 wards in the hospital. 12 respondents would be sampled from each ward if they are eligible for the study. INCLUSION CRITERIA Respondents must be registered healthcare workers in the Tamale Teaching Hospital. EXCLUSION CRITERIA Medical, nursing and other clinician students are excluded from this study. DATA COLLECTION TOOL A well-structured questionnaire will be used to collect socio-demographic data, knowledge on handwashing from the respondents. PROCEDURE FOR DATA COLLECTION Probability sampling technique will be used. This is to help get an equal proportion of participants from the various wards used. The data collection will employ the use of structured questionnaire which respondents will check and will also give short answers to some questions to solicit data from respondents. All the wards will be successfully visited on a daily basis to get eligible participants for the study. These wards will be visited on a daily bases recruiting respondents until the last questionnaire is administered. The wards in the Tamale Teaching Hospital include; Purposive sampling will be used to select clinicians from the hospital who will be available during the data collection from Tamale Teaching Hospital. The study data will be collected based on the socio-demographic characteristics of respondents, general knowledge about handwashing, assess the differences across age groups, gender and their experiences regarding handwashing through the use of a structured questionnaire administered by the research assistants with minimal clarification from the research assistants. Primary data will be collected and used in the analysis. DATA ANALYSIS The data will be coded in excel and then entered into SPSS V.16 for analysis. Responses will be assigned codes in the form of numbers, which will make it easy for keying in the responses into a computer format. Univariate analysis will be done for socio-demographic characteristics of respondents and also for areas that require only descriptive statistics. Bivariate analysis will be performed to find associations or relationships between socio-demographic characteristics and level of knowledge, attitudes and practices of clinicians on handwashing. Likert item was rated on a 1-5 response scale; where strongly agree=5, agree-4, neutral=3, disagree=2, strongly disagree=1. The scores were graded into positive, neutral or negative. ETHICAL CONSIDERATIONS Ethical approval to use the hospital was from the Ethics and Research Committee of the hospital. Formal consent will also be obtained from the respondents prior to administration of questionnaire. Individual participants will be told that the study is purely for academic purpose and names as well as addresses will not be and also needed assuring them of their privacy and confidentiality. Respondents were also told that they had the right not to participate in the study. LIMITATIONS OF THE STUDY The cost and inexperience of researchers in conducting this study will be a challenge. Also, bias in the sampling procedure can also occur. REFERENCES Abd Elaziz, K.M. Bakr, I.M (2009) .

Client And Server Architecture :: Networks Telecommunications

Most organization today are moving to client server architectures. Client server attempt to balance the processing between the client and the server by having both do some of the logic. In these networks, the client is responsible for the presentation logic, while the server is responsible for the data access logic and data storage. The application logic may reside on the client on the client or on the server, or it may be split between both. These are many ways in which the application logic can be partitioned between the client and the server. The type of the client server consists of two-tier, three-tier and multi-tier client server. Two-tier client server is one of the most common. In this case, the server is responsible for the data and the client is responsible for the application and presentation. The two-tier client server is uses only two sets of computers, one client and one server. For example, the database management system (DBMS) runs in the server. A request from the client is sent to the DBMS, which responds by searching the server and sending only the result to the client. If 100 records matched the criteria in our million-record example, only 100 kilobytes of data traverse network rather than one gigabyte. Another type of client server architectures is three-tier client server uses three sets of computers. In this case, the software on the client computer is responsible for presentation logic, an application server is responsible for the application logic, and a separate database server is responsible for the data access logic and data storage. Three-tier client server Beside that, the web really is a client server. Because on the server side, the web uses a multi-tier architecture with interlinked web server, application servers, database servers and caching servers. On the client side, user machines commonly execute scripts embedded in countless web pages. They also execute java applets, java programs and rich client application, all of which means that both client and server cooperate in tandem. Advantages and disadvantages of these method The client server architecture does not propose any new model or architecture, but it simply allows users to get more processing power for developing their business network applications in a cooperative processing environment. It does not define any new infrastructure, but it uses the existing structure and new user interface tools. It integrates these new tools and the concepts of the distributed architecture to define a new computing environment which will enhance productivity at much lower operating costs.
