The Poisson Probability Distribution

The Poisson probability distribution, named after the French mathematician Simeon-Denis. Poisson is another important probability distribution of a discrete random variable that has a large number of applications. Suppose a washing machine in a Laundromat breaks down an average of three times a month. We may want to find the probability of exactly two breakdowns during the next month. This is an example of a Poisson probability distribution problem. Each breakdown is called an occurrence in Poisson probability distribution terminology.The Poisson probability distribution is applied to experiments with random and independent occurrences. The occurrences are random in the sense that they do not follow any pattern, and, hence, they are unpredictable. Independence of occurrences means that one occurrence (or nonoccurrence) of an event does not influence the successive occurrences or nonoccurrences of that event. The occurrences are always considered with respect to an interval. In the ex ample of the washing machine, the interval is one month. The interval may be a time interval, a space interval, or a volume interval.The actual number of occurrences within an interval is random and independent. If the average number of occurrences for a given interval is known, then by using the Poisson probability distribution, we can compute the probability of a certain number of occurrences, x, in that interval. Note that the number of actual occurrences in an interval is denoted by x. The following three conditions must be satisfied to apply the Poisson probability distribution. 1. x is a discrete random variable. 2. The occurrences are random. 3. The occurrences are independent.The following are three examples of discrete random variables for which the occurrences are random and independent. Hence, these are examples to which the Poisson probability distribution can be applied. 1. Consider the number of telemarketing phone calls received by a household during a given day. In t his example, the receiving of a telemarketing phone call by a household is called an occurrence, the interval is one day (an interval of time), and the occurrences are random (that is, there is no specified time for such a phone call to come in) and discrete.The total number of telemarketing phone calls received by a household during a given day may be 0, 1, 2, 3, 4, and so forth. The independence of occurrences in this example means that the telemarketing phone calls are received individually and none of two (or more) of these phone calls are related. 2. Consider the number of defective items in the next 100 items manufactured on a machine. In this case, the interval is a volume interval (100 items).The occurrences (number of defective items) are random and discrete because there may be 0, 1, 2, 3, †¦ , 100 defective items in 100 items. We can assume the occurrence of defective items to be independent of one another. 3. Consider the number of defects in a 5-foot-long iron rod. The interval, in this example, is a space interval (5 feet). The occurrences (defects) are random because there may be any number of defects in a 5-foot iron rod. We can assume that these defects are independent of one another. The Poisson Probability Distribution The Poisson probability distribution, named after the French mathematician Simeon-Denis.

Key words: Self medication, youngsters, trend, prescription. 1 INTRODUCTION 1. 1 Background of the study Self-medication is defined as obtaining and using medicine without the suggestion of a doctor either for diagnosis. Drugs for self-medication are normally name as ‘nonprescription' or ‘over the counter' (OTC) and are obtainable without advice of doctor's through chemists. Self medication is nowadays gradually being considered as a self-care component.Support of self-care is seen as give patients' every view to take accountability and create self-confidence in their ability to deal with their own health. Unlike other characteristics of self-car e, self-medication involves the use of medicines and medicines have the potential to do better as well as cause harm. This is mainly concern to these countries where there is lack of enforcement of system leading to accessibility of non prescription medicines over the counter like Pakistan. This results in extensive use of such drugs which is related with serious undesirable effects.Numerous cases studies have stated that unsuitable self-medication outcomes in wastage of resources and causes serious health hazard such as unwanted drug reactions, prolonged suffering and drug dependence. When the medication correctly done, self-medication might be save the time which spent in waiting to see a physician, may be cost-effective and also propose savings for medical schemes and the general healthcare system. The WHO has also pointed out that dependable self-medication can help patient and treat illness that do not need medical consultation and gives a cheaper option for treating common dis eases.With self-medication, the person tolerates primary accountability for the use of self-medication products. All parties concerned in self-medication should be attentive of the advantages and disadvantages of any self-medication product. Through many studies have been conducted in different populations to appraise the practice of self-medication there is a scarceness of studies on self-medication among university and medical students. To enhance our knowledge we carry on this agenda and targeted the youngsters to find out the practices of self-medication in youngsters of Karachi.This study is conduct on trend of Self-medication in youngsters of Karachi. Self medication trend is continuously increasing in youngsters. This study might be helpful to determine the rate of self medication in youngster of schools, colleges and universities of Karachi. This study also explores the injurious effects of self medication, causes for not discussing with the doctor and general issues for whi ch students rely on self medication. Self-medication is the healing of general health issues with drugs particularly proposed and labeled for utilize without any medical prescription and permitted as safe and useful for such medical issues.To enhance our information, we conduct this study in Karachi and especially target the youngsters to evaluate self medication in the youth. In Karachi, approximately every chemist sells medicines without a prescription of doctor; a phenomenon seen in many is developing countries. Self medication is a part of health care and it is measured as initial public health source in system of health care. Use of non-prescription medicines by people on their own initiative is a part of self medication and it is in common practice in youngsters for common issues related to their health.Self medication also encompasses the use of the medicines by the users for self perceived health problems or the continuing use of medications formally prescribed earlier. Furt her broading of the definition includes treatment of family members especially to minor and elderly. Adverse effects of self medication Its very common in our society that whenever we catch a cough, flu or any common disease we have fixed a prescription in our mind and we do self-medication in such situations. We ask any of our friends or neighbors who prescribes the medicine which was effective for him.We do these types of things but the main thing we forget in all this is going to a doctor. Some adverse effects of self-medication are as follows. Insomnia Due to self-medication you can face the problem of insomnia. Insomnia is a sleeping disorder this is very common now a days and one of the major reason to insomnia is self-medication. When this problem occurs again open you medicine box and do self-medication again for this problem too. This worsens your problem. When you take one type of medicine again and again you may addicted to it and you also get dependent on such medicines. Skin problems When you involve in self medication you will get some skin problem or any other allergy due to reaction of medicine.

The counter sales of nearly all medicine are available without any prescription or regulation this is one of the majo r factor probably contributing to this phenomenon. In the practice of our dermatology, we commonly meet patients with acne infections due to use of topical self medication. The prevalence of self medication is extensively high in the acne infections patients in our residents.The most frequently used medication was potent topical steroids. 2. 2 Self-Medication practices According to Shankar et al (2002) Mild illness is the most common reason of self-medication which is mentioned in the literature, prior knowledge of treating related disease, lack of availability of healthcare personnel and financial considerations. Analgesics and antimicrobial are commonly used for self medications. In addition to allopathic medicines,  herbal medicines were also usually used for self-medication. 2. 3 Reasons for self-medication practiceAccording to Almasdy et al, (2011) Among university students the major reason for self-medication were their prior experiences and the majority of the authors agree d with this major reason of self medication, their health problems was measured as too insignificant and time savings. Family or friends guidance, non availability of transport, doctor was not available, capability to self-manage the symptom, urgency of the problem and have adequate information were other main reasons for self-medication practice.Have reported that the main reasons to self-medication practice among university student were lack of time and low cost consultation. 2. 4 Demographic characteristics and prevalence of self medication practice According to Hussain et al. (2011) many of these researches mentioned the mean age of undergraduates was under 25 years old. This was reflected by the majority of the samples was undergraduate students. In manner of sexual characteristics, prevalence of the undergraduates who have involved in self-medication is female.Three of these researches have been engaged to undergraduates majoring in equally health and non-health courses, while two of the studies have engaged to undergraduates simply majoring in health, and the rest did not revealed the field of the undergraduates involved in the studies. Frequency of self-medication observed among the university student was diverse. The occurrence of self-medication reported was mainly depend on how the query was created in the questionnaire.For example, the occurrence reported was authentic, if the question was concerned to the modern practice of self-medication. On the contrary, when asked whether the students had used any medication for the past one month, the incidence reported was low. However, some studies did not report the prevalence of self medication. Due to the difference in the methods used in studies, therefore, it is quite difficult to estimate the true prevalence rate of self-medication in university students. 2. 5 Benefits and Risks of Self Medication According to Carmel M et al. 2001) Practices of self-care for mild illnesses are increasingly encouraging by some governments, including self-medication. Support of self-care is observed as giving all probability to patients to take accountability and construct confidence in their capability to control their own health. Patient confidence is observed as a helpful step in the improvement of the correlation between patient and healthcare provider and is described as an significant health policy model. 2. 6 In? uences on Knowledge and Attitudes about Prescription Drugs among Teens.According to Twombly et al, (2008) escalating precise information about the hazards of recommended medicines misuse is expected to reduce misuse. In fact, there is an inverse relationship between level of perceived risk and likelihood of use when it comes to teenagers’ willingness to misuse prescription drugs. 2. 7 Symptoms leading to self-medication According to Zafar et al. (2008) Approximately in Pakistan, everyone can get medicine without any prescription, mostly pharmacy selling medicines without a d octor advise; this incident observed in every developing nations.Even, antibiotics and high potential medicines are easily available to the common man. The common practices of self-medication among undergraduates is leading to the main symptoms of self-medication were headache or mild pain; fever; flu, caught and cold; and diarrhea. Others symptoms includes allergy, skin problems, inability to sleep, vomiting, eye and ear symptoms, menstrual syndrome and others minor problems. This case study shows the outcome of the Pakistani youth's information, mind-set, and practice towards self medication. 2. 8 Sources of drug informationAccording to Hussain et al, (2008) in this research, the author explains sources of drug information in self-medication practice. In this research statement shows that the undergraduates obtain access to drug information from many resources. Which is relate to their own earlier experience, family, contacts or university course mates, pharmacy sales representati ve, doctor or nurse, and advertisement in the television, radio, newspaper, magazine or books. 2. 9 Problems-related to self-medication practices According to James et al, (2006) a new important findings significance of elf-medication highlighted in this literature was the effect of health instruction on the knowledge of drug’s side-effects amid the self medicating undergraduates. Calculate the effect of exposure to medical knowledge to equally the first year and senior medical undergraduates. The research exposed that troubles linked with self-medications were fewer in senior medical undergraduates as contrast to the first year students. Less awareness of medical information may be reason to the low self-assurance of the first year medical students 2. 0 Self -Medication among university students According to Mumtaz et al, (2011) Self medication mounting the probability of illegal use of medicine and medicine addiction and due to this the symptoms of disease are underlying th us are complicating the problem, produce drug resistance and create difficulty to diagnosis. On the other side many of people involved in self medication who accept accountability and are cautious is a source saving phenomenon to the health system. Easy accessibility of the medicine by the counter sales increases self medication.Self medication is a phenomenon and practiced almost in the countries all over the world with different prevalence. In the low and middle income countries, commonness of self medication is higher. This research is explained that the educated people tend to practice self medication more than uneducated peoples. According to this research the frequency of self medication among undergraduates of medical and non medical is nearly 80%. This study endorses earlier reported local estimates of self medication among university students. . 11 Self-Medication in Nigeria According to Fadare et al, (2011) now a day’s Self-medication is growing in the population ma ny counties as a common type of self-care behavior. Many global researches have explored the frequency and characteristics of self-medication practices at the resident’s level. In Nigeria, many studies conduct to find the frequency of self-medication in general; still the frequency of antibiotic self-medication among medical undergraduates has not been conducted.The interest in studying this practice among this select group is due to the fact that they are the future prescribes and health educators of the population of Nigeria. 2. 12 Evaluation of Self-Medication According to SD Sontakke et al, (2011) The World Health Organization has also identified that proper self-medication can help patients and treat illness that do not need medical consultation and gives a cheaper substitute for treating common diseases. With self-medication, the person takes primary accountability for the use of self-medication products.Every individual must be aware of advantages and disadvantages of self medication products who involved in self-medication practices . however many researches has been conducted in different populations to assess the frequency of self-medication there is a paucity of studies on self-medication among medical students. Support of self-care is considered as providing patients' every opportunity to construct self-confidence in their capability to control their own health. Unlike other aspects of self-care, self-medication involves the use of drugs and drugs have the potential to do good as well as cause harm. . 13 Self-medication in Sri lanka According to Wijesinghe et al, (2012) Self medication growing with increasing literacy and it is even appreciated so as to have self-sufficiency for healing, preventive , primitives and rehabilitative care . If done properly, it is helpful to save expenses of health care seekers. therefore, considering the usefulness of self-medication, the World Health Organization (WHO) has focused to develop strategy for regul atory estimation of the medicines suitable for self-medication. he frequency of Self-medication is very familiar among women, youngster, those individuals who living alone and the individuals who belongs to low financial status (SES), sufferers of chronic ailments and psychiatric conditions. Many researches in Sri Lanka were conducted to city areas which have well built-up health and hospitals networks. Substitute indicators such as self-medication prevalence for malaria indicate that self-medication is relatively low in rural areas. 2. 14 Self-Medication pattern in Punjab According to S Shveta et al, (2011) the frequency of self medication practices is common in the state.Fever, cough and cold are reasons for the use of self-medication. The most common drugs which is commonly used for self-medication is tonics and food supplements and it is taken frequently without prescription. We recommend that holistic approach should be taken to prevent this problem, which contain correct knowl edge and information regarding the self medication and strictness concerning pharmaceutical marketing. Furthermore especially in case of Punjab state ban must be implemented on counter sale of medicines. Dispensing modes in the state required to be enhanced by proper education, regulatory and administrative strategies. . 15 Self-Medication in Children’s According to Oshikoya et al, (2007) medicine use in children is of great anxiety worldwide and has received a lot of attention. Various researches have been performed in the urbanized and developing countries, and have all the countries faced many problems from mistreat and abuse of recommended medicines, and errors of medications. Children include a larger percentage of the residents in developing countries and are responsible to many illnesses as a effect of poverty. The majority of medicines in children are used outside of hospitals, both as recommended and non- recommended medicines.The primary reply by the majority famili es too many diseases in their children has been found to be use of non-prescribed medicines . Self-medication is very common among urban children in Nigeria. The presented laws concerning the use and sale of over the counter medicine, prescribed and non-prescribed drugs must be reinforced to ensure normal use of medicines. 2. 16 Self-medication practices for drug consumers According to Andualem et al, (2004) On Socio-demographic the respondents concealed the characteristic of drug consumers consist of all age category like both genders, pregnant women and breast-feeding mothers.Self-medication illnesses that reported very commonly in the respondents were headache, fever, cold, respiratory tract infection and gastrointestinal diseases. Education for the self-medication should be provided to public as well as health care providers ;i. e; this type of illnesses can be easily self-treated and diagnosed and the drug products to be used in promoting the responsible self-medication. 2. 17 Self-medication in West Uttarpradesh According to Ghosh et al, (2010) some students reported that they were alcoholic, smoker or involve in some chronic problems i. . non-communicable diseases, they have less awareness about the medicines that they use with smoking, alcohol or suffer problems with chronic diseases. Non-seriousness related to the disease is the most common reason reported for self-treated and for self-medication, previous experience on the medicine and emergency use. 2. 18 Assessment of Self-medication According to Sawalha, (2007) In An-Najah students the preference of self-medication in very common. Practice of treating this condition is done either simple or by previous experience.Even important self-medication predictors did present in the studied group, types of medications knowledge on the level of self-care orientation can be significant in analyzing the self-medication practices. 2. 19 Health care strategies According to Haider et al, (1995) treatment from som e medical systems found in majority of cases. Health care behavior for childhood illnesses and assessment of the degree and the reasons for self-medication assess in Karachi, Pakistan. The main reason is the good past experience of self-medication. he main reason is the use of different medicines by health professional that influence the parents for self-medicate to their children. Self-medication is hard to reduce but some information can be made to discourage wrong use of harmful drugs. 2. 20 Self-medication (WHO). According to WHO (1988) The WHO pointed that Self medication can help and treat illness that does not require any consultation of medication and provides a cheaper option for treat such common diseases. Yet, the person bears basic responsibility for the use of self-medication products.Due to self-medication products parties should be aware about the benefits and risks of self-medication. 3 METHADOLOGY This part presents an overview of the methods to be used in the study . Areas covered in this part include data collection, variables, sample and sampling techniques and model for analyzed the data. 3. 1 Data In this study primary data is used for gathering information. A survey was conducted in 4 areas of Karachi, Pakistan during May 2012. Data collection was entered using SPSS version 17 to generate descriptive statistics.Data analyzed complete using chi-square test to check the associations between variables. 3. 2 Variables Variables used in this study are 1.

The counter sales of nearly all medicine are available without any prescription or regulation this is one of the majo r factor probably contributing to this phenomenon. In the practice of our dermatology, we commonly meet patients with acne infections due to use of topical self medication. The prevalence of self medication is extensively high in the acne infections patients in our residents.The most frequently used medication was potent topical steroids. 2. 2 Self-Medication practices According to Shankar et al (2002) Mild illness is the most common reason of self-medication which is mentioned in the literature, prior knowledge of treating related disease, lack of availability of healthcare personnel and financial considerations. Analgesics and antimicrobial are commonly used for self medications. In addition to allopathic medicines,  herbal medicines were also usually used for self-medication. 2. 3 Reasons for self-medication practiceAccording to Almasdy et al, (2011) Among university students the major reason for self-medication were their prior experiences and the majority of the authors agree d with this major reason of self medication, their health problems was measured as too insignificant and time savings. Family or friends guidance, non availability of transport, doctor was not available, capability to self-manage the symptom, urgency of the problem and have adequate information were other main reasons for self-medication practice.Have reported that the main reasons to self-medication practice among university student were lack of time and low cost consultation. 2. 4 Demographic characteristics and prevalence of self medication practice According to Hussain et al. (2011) many of these researches mentioned the mean age of undergraduates was under 25 years old. This was reflected by the majority of the samples was undergraduate students. In manner of sexual characteristics, prevalence of the undergraduates who have involved in self-medication is female.Three of these researches have been engaged to undergraduates majoring in equally health and non-health courses, while two of the studies have engaged to undergraduates simply majoring in health, and the rest did not revealed the field of the undergraduates involved in the studies. Frequency of self-medication observed among the university student was diverse. The occurrence of self-medication reported was mainly depend on how the query was created in the questionnaire.For example, the occurrence reported was authentic, if the question was concerned to the modern practice of self-medication. On the contrary, when asked whether the students had used any medication for the past one month, the incidence reported was low. However, some studies did not report the prevalence of self medication. Due to the difference in the methods used in studies, therefore, it is quite difficult to estimate the true prevalence rate of self-medication in university students. 2. 5 Benefits and Risks of Self Medication According to Carmel M et al. 2001) Practices of self-care for mild illnesses are increasingly encouraging by some governments, including self-medication. Support of self-care is observed as giving all probability to patients to take accountability and construct confidence in their capability to control their own health. Patient confidence is observed as a helpful step in the improvement of the correlation between patient and healthcare provider and is described as an significant health policy model. 2. 6 In? uences on Knowledge and Attitudes about Prescription Drugs among Teens.According to Twombly et al, (2008) escalating precise information about the hazards of recommended medicines misuse is expected to reduce misuse. In fact, there is an inverse relationship between level of perceived risk and likelihood of use when it comes to teenagers’ willingness to misuse prescription drugs. 2. 7 Symptoms leading to self-medication According to Zafar et al. (2008) Approximately in Pakistan, everyone can get medicine without any prescription, mostly pharmacy selling medicines without a d octor advise; this incident observed in every developing nations.Even, antibiotics and high potential medicines are easily available to the common man. The common practices of self-medication among undergraduates is leading to the main symptoms of self-medication were headache or mild pain; fever; flu, caught and cold; and diarrhea. Others symptoms includes allergy, skin problems, inability to sleep, vomiting, eye and ear symptoms, menstrual syndrome and others minor problems. This case study shows the outcome of the Pakistani youth's information, mind-set, and practice towards self medication. 2. 8 Sources of drug informationAccording to Hussain et al, (2008) in this research, the author explains sources of drug information in self-medication practice. In this research statement shows that the undergraduates obtain access to drug information from many resources. Which is relate to their own earlier experience, family, contacts or university course mates, pharmacy sales representati ve, doctor or nurse, and advertisement in the television, radio, newspaper, magazine or books. 2. 9 Problems-related to self-medication practices According to James et al, (2006) a new important findings significance of elf-medication highlighted in this literature was the effect of health instruction on the knowledge of drug’s side-effects amid the self medicating undergraduates. Calculate the effect of exposure to medical knowledge to equally the first year and senior medical undergraduates. The research exposed that troubles linked with self-medications were fewer in senior medical undergraduates as contrast to the first year students. Less awareness of medical information may be reason to the low self-assurance of the first year medical students 2. 0 Self -Medication among university students According to Mumtaz et al, (2011) Self medication mounting the probability of illegal use of medicine and medicine addiction and due to this the symptoms of disease are underlying th us are complicating the problem, produce drug resistance and create difficulty to diagnosis. On the other side many of people involved in self medication who accept accountability and are cautious is a source saving phenomenon to the health system. Easy accessibility of the medicine by the counter sales increases self medication.Self medication is a phenomenon and practiced almost in the countries all over the world with different prevalence. In the low and middle income countries, commonness of self medication is higher. This research is explained that the educated people tend to practice self medication more than uneducated peoples. According to this research the frequency of self medication among undergraduates of medical and non medical is nearly 80%. This study endorses earlier reported local estimates of self medication among university students. . 11 Self-Medication in Nigeria According to Fadare et al, (2011) now a day’s Self-medication is growing in the population ma ny counties as a common type of self-care behavior. Many global researches have explored the frequency and characteristics of self-medication practices at the resident’s level. In Nigeria, many studies conduct to find the frequency of self-medication in general; still the frequency of antibiotic self-medication among medical undergraduates has not been conducted.The interest in studying this practice among this select group is due to the fact that they are the future prescribes and health educators of the population of Nigeria. 2. 12 Evaluation of Self-Medication According to SD Sontakke et al, (2011) The World Health Organization has also identified that proper self-medication can help patients and treat illness that do not need medical consultation and gives a cheaper substitute for treating common diseases. With self-medication, the person takes primary accountability for the use of self-medication products.Every individual must be aware of advantages and disadvantages of self medication products who involved in self-medication practices . however many researches has been conducted in different populations to assess the frequency of self-medication there is a paucity of studies on self-medication among medical students. Support of self-care is considered as providing patients' every opportunity to construct self-confidence in their capability to control their own health. Unlike other aspects of self-care, self-medication involves the use of drugs and drugs have the potential to do good as well as cause harm. . 13 Self-medication in Sri lanka According to Wijesinghe et al, (2012) Self medication growing with increasing literacy and it is even appreciated so as to have self-sufficiency for healing, preventive , primitives and rehabilitative care . If done properly, it is helpful to save expenses of health care seekers. therefore, considering the usefulness of self-medication, the World Health Organization (WHO) has focused to develop strategy for regul atory estimation of the medicines suitable for self-medication. he frequency of Self-medication is very familiar among women, youngster, those individuals who living alone and the individuals who belongs to low financial status (SES), sufferers of chronic ailments and psychiatric conditions. Many researches in Sri Lanka were conducted to city areas which have well built-up health and hospitals networks. Substitute indicators such as self-medication prevalence for malaria indicate that self-medication is relatively low in rural areas. 2. 14 Self-Medication pattern in Punjab According to S Shveta et al, (2011) the frequency of self medication practices is common in the state.Fever, cough and cold are reasons for the use of self-medication. The most common drugs which is commonly used for self-medication is tonics and food supplements and it is taken frequently without prescription. We recommend that holistic approach should be taken to prevent this problem, which contain correct knowl edge and information regarding the self medication and strictness concerning pharmaceutical marketing. Furthermore especially in case of Punjab state ban must be implemented on counter sale of medicines. Dispensing modes in the state required to be enhanced by proper education, regulatory and administrative strategies. . 15 Self-Medication in Children’s According to Oshikoya et al, (2007) medicine use in children is of great anxiety worldwide and has received a lot of attention.

Children include a larger percentage of the residents in developing countries and are responsible to many illnesses as a effect of poverty. The majority of medicines in children are used outside of hospitals, both as recommended and non- recommended medicines.The primary reply by the majority famili es too many diseases in their children has been found to be use of non-prescribed medicines . Self-medication is very common among urban children in Nigeria. The presented laws concerning the use and sale of over the counter medicine, prescribed and non-prescribed drugs must be reinforced to ensure normal use of medicines. 2. 16 Self-medication practices for drug consumers According to Andualem et al, (2004) On Socio-demographic the respondents concealed the characteristic of drug consumers consist of all age category like both genders, pregnant women and breast-feeding mothers.Self-medication illnesses that reported very commonly in the respondents were headache, fever, cold, respiratory tract infection and gastrointestinal diseases. Education for the self-medication should be provided to public as well as health care providers ;i. e; this type of illnesses can be easily self-treated and diagnosed and the drug products to be used in promoting the responsible self-medication. 2. 17 Self-medication in West Uttarpradesh According to Ghosh et al, (2010) some students reported that they were alcoholic, smoker or involve in some chronic problems i. . non-communicable diseases, they have less awareness about the medicines that they use with smoking, alcohol or suffer problems with chronic diseases. Non-seriousness related to the disease is the most common reason reported for self-treated and for self-medication, previous experience on the medicine and emergency use. 2. 18 Assessment of Self-medication According to Sawalha, (2007) In An-Najah students the preference of self-medication in very common. Practice of treating this condition is done either simple or by previous experience.Even important self-medication predictors did present in the studied group, types of medications knowledge on the level of self-care orientation can be significant in analyzing the self-medication practices. 2. 19 Health care strategies According to Haider et al, (1995) treatment from som e medical systems found in majority of cases. Health care behavior for childhood illnesses and assessment of the degree and the reasons for self-medication assess in Karachi, Pakistan. The main reason is the good past experience of self-medication. he main reason is the use of different medicines by health professional that influence the parents for self-medicate to their children.

The importance of literacy development in terms of life success Essay

The importance of literacy development in terms of life success - Essay Example Moreover, the notion of literacy is greatly expanded (informational, technical, financial literacy, etc.) and acquires some status of culture’s attribute. Already this issue is not about the availability of key areas of literacy, the question now should be put on the expansion of the general population literacy to the level of culture (information culture, scientific, technical, social, etc.). Thus, we are going to discuss different kinds of literacy and the importance of its development in terms of life success. First of all, it is necessary to mention that ‘literacy’ from a traditional point of view is a definite degree that is mastered by a person in accordance with grammatical rules of native language. Concerning the characteristics of the population – it is one of the basic indicators of its socio-cultural development. The need for literacy and learn reading, writing and arithmetic related to the occurrence of a pictographic writing system, and has its roots in early society. The transition of society to symbolic and graphical ways to store and transfer socially relevant information is a huge leap in the cultural and social development of mankind. According to Cope and Kalantzis, â€Å"literacy is at the heart of education’s promise† (Cope and Kalantzis, 2000). As a result, literacy has become an essential tool of possession of written culture. The specific content of the concept of literacy has changed historically, expanding with increasing public demands for the development of the individual - from basic skills to read, write, count, etc. to the possession of minimum socially necessary knowledge and skills (functional literacy). In addition Cope and Kalantiz emphasized that â€Å"literacy represents a kind of symbolic capital in two senses: as the preeminent form of symbol manipulation that gets things done in modern times and as a symbolic marker of being educated† (Cope and Kalantiz, 2000). Thinking abou t the historical background of the literacy development’s problem it is known that issues regarding the term ‘literacy’ definition, its statistical characteristics were considered at international meetings on statistics and census programs since the end of XIX century. UNESCO General Conference (10th session, Paris, 1958) recommended all countries in conducting censuses â€Å"to consider literate such persons who can read with comprehension and write a brief statement about their everyday lives† (Brandt, 2001). The semi-literate person in that context was a person who was able only to read. A term of functional literacy was proposed at the World Congress of Ministers of Education on literacy (Tehran, Sept. 1965), and a text of recommendations of the International Standardization of Educational Statistics, proposed by UNESCO, was revised in 1978. Street said that â€Å"Initially, functional literacy was used to refer to the needs of employment and economic development† (Street, 2001). Moreover, â€Å"the concept was then broadened to include the print demands of occupational, civic, community and personal functioning† (Street, 2001). According to a new edition of this document, it is necessary to consider a literate person who can be engaged in all activities in

Look at the directions I uploaded Term Paper Example | Topics and Well Written Essays - 1750 words

Look at the directions I uploaded - Term Paper Example A manager would be effective in his respective roles when he understand the strategic, technical and operational responsibilities he holds within the workplace (â€Å"Henry Mintzberg’s Managerial,† n.d.). What are specific roles this first category consists? These set of roles are associated on how a manager will interact to his employees and the entire workforce in general. These are the first three roles out of the 10 roles of management by Henry Mintzberg – figurehead, leader and liaison (Burgaz, 1997, p. 15). The first is a symbolic head. A manager is expected to perform routine duties legally and socially. He is like a father. The father is the head of the family. He is expected to initiate actions for the welfare of his family. In the same manner, if the organization needs resources to complete certain projects, he would initiate actions to provide these resources to ensure productivity. In a social gathering within the organization, a manager may send soli citation letter to sister companies and other organizations requesting them to participate and donate to the said event. He is also the leader of the workforce, which is the second crucial role of a manager. Mr. A, for example, is responsible to motivate his employees. He is responsible to initiate and conduct training to enhance the skills of his subordinates. He is also in charge to fill vacant positions and activate the workforce to perform the tasks and duties as defined in their respective job descriptions. As a leader, he must learn how to follow the rules and protocols of the company or organization. As a leader, he must portray the right attitude in the workforce to become an ideal person and to strengthen his authority with his employees. Authority is not enough for a manager to become effective with his roles – he needs respect and he must learn to gain it from his employees. Mr. A. acts as the liaison officer – that is the manager’s third role. He sha ll facilitate communications between organizations (â€Å"Roles and Responsibilities†, 2012). He maintains a self-developed contact to the outsiders and other companies for the benefit of the organization (Burgaz, 1997, p. 15). Mr. A. needs to know the news outside which can affect his operation and decision-making factors. These outside contacts are expected to provide favors and important data to help him activate the workforce efficiently. In order to build a self-developed network between outsiders, he needs to build a strong relationship to these outside parties for them to entrust him with unbiased details. What are informational roles? Mr. A. is expected to monitor, disseminate and transmit information for the benefit of the entire organization. He seeks and receives different information that would help him develop an effective techniques and strategies to make the entire workforce productive. Mr. A. would monitor his subordinates’ performance and measures it p roductivity. He must exert extra effort to gather information from the outside – e.g. examining the competitors techniques. Most of the times, people reinvent ideas rather than building something from scratch. Competitors are spending millions of cash to enhance their management techniques and approaches – a wise manager can make use of these data and information as important resources to develop an approach suited for his management. Disseminating information to the organization is

Information Management Essay Example | Topics and Well Written Essays - 2250 words

Information Management - Essay Example Evolution of Information Systems Over the decades, technology has evolved manifolds. The major enhancements pertaining to the technological developments involve the communication media. Transfer of information amongst the users has always been a critical issue embedded in the communication strategies. Business environments have imbibed the technology trends up to a great extent in order to enhance their functionality as a complete unit that integrated diverse areas of work (Govindaraj, 2001). The necessity to manage all the data and information related to the vendors, consumers, employees, work processes, business transactions, stakeholders and so on had to be addressed to the minutest details. This issue demanded for an evolution of a system that could store all the information generated at diverse fields of work and support the handling of information in a limpid manner. The system that provides the infrastructure to manage and maintain such task is known as â€Å"Information Systems Provision†. Implementation of Information Systems Information Systems is implemented on the type of the information, whose analysis is required to understand the processes and parameters linked to the data. This data may be acquired from various fields of the concerned business environment (Warboys, Kawalek, Robertson and Greenwood, 1999). Following are the requirements to implement an Information System for a marketing division. To model the dynamics of the processes those effect the production.

Immigration Essay Example | Topics and Well Written Essays - 2750 words

Immigration - Essay Example Wood (2004) sees domestic violence as a ‘crime that does not recognize racial, cultural, or socioeconomic barriers’. In brief, economic, cultural or political development of a given community does not automatically ensure the protection of the rights of women against being the victims of various types of gendered violence. Although domestic violence and other types of violence on women are prevalent among almost all the social groups, its nature and degree are different from community to community. Thus, the violence on immigrant women is so rampant and involves issues and concerns that are radically different from those pertaining to other social sections. It means that the social settings in which an immigrant woman is uniquely placed makes her more vulnerable for being the victim of various types and degrees of sexual and gendered violence than other sections of women citizenry. In addition, the conditions of undocumented immigrant women are even more exploitative and oppressive as they are systemically exempted from the cover of the law of the land. The introduction of Violence Against Women Act (VAWA) in 1994 has marked a turning point on the legal debate over the issue of increasing violence on immigrant women and its social consequences. The merits and drawbacks of the VAWA are on the focus of attention since its very introduction. Demands for amendments to the VAWA have been raised from around the corners for not only making it more effective but also casting off its perceived and real ills. Even, it is possible to identify a ‘VAWA discourse on the violence on immigrant women’ that encompasses almost all the possible aspects of the concerns pertaining to the human rights of immigrant women. The purpose of this paper is to overview the issues of immigration and the violence on immigrant women and analyzes it as a policy matter that must address unique social, political, economic, and cultural factors and include

To what extent does disparity exist with the legalization of the birth Essay

To what extent does disparity exist with the legalization of the birth control movement in regards to poor and minority women in the United States - Essay Example But both prevented the spread of birth control by changing from a popular, participatory cause to a professional operation (Gordon, 1975). The most prominent activist is Margaret Sanger. She is known the founder of the birth-control movement in the United States was Margaret Sanger. She has witnessed the results of uncontrolled fertility, self-induced abortions, and high rates of infant and maternal mortality. Her experiences as a nurse and midwife led her to focus all her energy on the single cause of reproductive autonomy for women. She was convinced that there is a need for extensive information on contraception. She established information and advice centers that help women in safe, effective and female controlled contraceptive. She founded the American Birth Control League which later became Planned Parenthood Federation of America. That time issues regarding birth control and contraception was considered obscene and this results to continuous government harassment and closure of her shops. The Comstock Act which was passed in 1873 states that it is illegal to convey any information or devices that could be used f or preventing conception and defined it as obscene was used against Sanger in her advocacy (Battaglia, 1998). It was the government that controlled the access of poor women to birth control, sterilization and abortion for the most part of the 20th century. Primarily concerned about the maternal and infant mortality, the officials began to offer access to birth control centers but women have limited access. Birth control has difficulty in finding legislative support mainly because of the eugenic rhetoric and arguments used by supporters to promote them. There are four main groups that influenced the nature and delivery of the policies. First are the medical and social scientists that offer theories about the origins and characteristics of poverty and proposed solutions that involved the control of reproduction. Second are the leading health and welfare professionals that shaped public policy and influenced the nature of reproductive services. Third, the state and county officials who implemented public health and welfare policies shaped the delivery of reproductive services. Finally, the poor and minority women targeted by the programs responded to them. Factors such as sexuality, class and racial conflicts shaped the negotiations over reproductive control. The ability of women to control their sexuality in terms and conditions of motherhood are the center of debates about birth control. Class and racial background determines whether women will have access to reproductive health care. It was assumed by Policy makers and health and welfare professionals that poor single mothers in particular if they are African American, Hispanic, or Native American-lacked the ability to function properly as mothers and that they should be discouraged from further childbearing.

Careers in Lodging and Food and Beverage Industries Essay - 2

Careers in Lodging and Food and Beverage Industries - Essay Example This explication concentrates on the lodging, food and beverage industries. The food, beverage and lodging industry constitutes diverse managerial careers, which require professionalism and utter commitment. Such managerial positions include human resource managers who efficiently direct, plan and coordinate the administrative duties of the organization. They authoritatively conduct and oversee interviewing, recruiting and eventual hiring of new staff (Davis, 2013). They also consult with ranking executives on strategic planning and pose as a link between an organization’s management of its workforce. Public relations managerial staff creates and upholds an auspicious public image for their clients or employer. They compose material for media publication, plan and lead public relations programs, and procure funds for their affiliation. In both industries, financial manager assume a key role in holding the responsibility for the financial health of the affiliation. They generat e financial reports, direct investment businesses and create strategies and plans for the financial goals of their affiliation. Advertising marketing and promotions managers compose programs to induce interest in a service or product (Davis, 2013). They operate with sales agents, monetary staff members and art directors. Food, beverage and lodging industries have operational managers in place. Their chief function is to assist the organization’s director in the healthy running of the businesses. They have the responsibility to create, deliver and design product mixes that have quality, while maintaining lump sum monetary returns (Davis, 2013). They do this while ensuring that all working prototypes are under critical review to induce growth and deliver outstanding guest services. Food service managers are explicitly responsible for overseeing the daily operations of restaurants and other affiliations that serve beverages and food to their clientele. These managers ensure that clientele derive sufficient satisfaction with their dining experience in the entire food and beverage industry (Davis, 2013). Maintenance managers in both establishments administer the yearly operating plans and establish yearly objectives and goals for the staff and departments, while reviewing work completion for efficiency and adequacy. This ensures accountability in the hospitality industry when such managers are active in their positions. The food, beverage industry has a career opportunity for directors of new merchandise sourcing, who have a chief responsibility to manage and invent new merchandise product lines. They additionally oversee sourcing selections and support new product introduction and production (Davis, 2013). They also levy for rapid prototyping, therefore they ought to have ample qualification handling such technical matters that are critical to the success of the food and beverage industry. In both industries under study, directors of sales have the mandate to develop an overall strategy with a corporate sense including creation of roadmaps for the affiliation. This is for ensuring that the organization acquires significant sales growth by extending sales in the present customer base. The have an additional role of developing the entire business (Davis, 2013)s. From the past to contemporary times, the hospitality industry ensues growing both internationally and nationally,

My Cousin Vinny Essay Example | Topics and Well Written Essays - 1000 words

My Cousin Vinny - Essay Example Surely this was mainly due to the police officer who kept harassing them, prodding them with questions such as, â€Å"At what point did you shoot the clerk?†, for example. One must realize that, if arrested, one has the right to have representation with one when answering questions, and one need not answer any questions one doesn’t want to, as it can and will be used against a person in a court of law. At trial, there were several errors of procedure and general blunders which would probably not happen in a real courtroom situation. â€Å"Vinny’s pre-trial research† was interesting.1 â€Å"Before the trial, Vinny interview[ed] key witnesses in person and trie[d] to envision how each one saw the crime.†2 At the arraignment, Vinny tries to argue the case instead of simply entering the plea of â€Å"not guilty,† a major mistake.3 Regarding opening statements, there is much to be said. This is a factual error. However, there were other things wrong with the opening statements. For example, Vincent came to court dressed appropriately (in a suit), but it was a red bellhop suit from a second-hand store that looked ridiculous. He wore this because the suit he usually would wear was unavailable, and he couldn’t wear his leather jacket to court. Although this might be a minor point, it is common for lawyers to dress professionally in a nice black or grey suit that has slacks and a jacket, with an appropriate knee-length or below skirt for women if it applies and they wish to wear one. Vincent’s opening statement, for his part, was very poor. Worse, when Vincent was challenged by the judge for his use of foul language in the courtroom, he said, â€Å"What?† and the judge found him in contempt of court for speaking rudely. Vincent also did not address the court by the term â€Å"Your Honor,† either, which was highly disrespectful. But that is just the tip of the iceberg here.

Investment and Portfolio Analysis Essay Example | Topics and Well Written Essays - 2000 words

Investment and Portfolio Analysis - Essay Example The understandings of market sentiments are very important for technical analysts and day-traders who try to maximize profits from stock price movement. The analysis of balance sheet of the company is found that the company has strong fundamentals including sufficient assets to cover its liabilities and there are no concerns regarding debt, payables, or inventory. With the help of several technical indicators, an investor will be able to analyze the relationship between price – volume and demand – supply for the overall market as well as the individual stock and make appropriate investment decisions. The company’s management has been able to successfully tackle the slow demand situation by introducing new products in the market at lower cost which increased the company’s sales volumes. With the increase in sales the company’s cost of production also increased at CAGR of 49% during the past three years. On the basis of these analysis and findings a s uitable recommendation can be given to investor regarding the attractiveness of the investment. The investment style of an individual varies from another depending on various opportunities and investment constraints. Individuals generally invest a certain portion of the surplus left after all necessary expenditures are carried out. The most common objective however is to maximize their return on investment. A proper fundamental and technical analysis generally provides a basic idea regarding these aspects and helps investors make informed investment decisions. Other factors like macroeconomic scenario, industry analysis, market sentiments and management analysis also plays an important factor in giving the best idea of a long or short sale investment decision. This report discusses these important investment tools with reference to a particular stock, which will help the investors a clue of

Christian Worldview Reflection Essay Example for Free

Christian Worldview Reflection Essay In the book, Be thou my vision: Pursuing God’s perspective in a pluralistic world it states , â€Å"provides life events and experiences that deposit eternal truths in our minds and lives, and make room for intimacy with Christ†. When I read this phrase it picked up my attention right away because I am a true believer that God always help us and never is going to leave us alone but, at the same time, I believe it is our job to be smart and choose the best choice. When I was 18 years old, God opened a door so I came to United States to play Soccer and to get a scholarship. Before that opportunity, I was not very close from Christ and never went to church and read the bible very often. Being here, I meet great people, the family that I stay with help me to get closer to God and I started going every Sunday to church and reading the bible more often. Since that moment, God is more present in my life and working through my life showing me His intimate love. With Christ being in my heart, my life has grown stronger and I try to follow His way the best that I can. The NIV of Proverbs 3:5-6 states, â€Å"Trust in the Lord with all your heart and lean not on your own understanding; acknowledge Him and He will make you path straight.† I believe that choosing that opportunity changed my life. I’m glad to be here and I am very grateful to God for giving me so good opportunities in my life. Now, it just depends on me to be successful in what I want and follow his word to be better follower of Christ

Classification Of Network Topology

Classification Of Network Topology The term topology refers that way in which the end points, or stations, attached to the network are interconnected or it is the arrangements of systems in a computer network. It can be either physical or logical. The physical topology refers that, how a network is placed in a physical way and it will include the devices, installation and location. Logical topology refers that how a data transfers in a network as opposed to its design. The network topology can be categorized into bus, ring, star, tree and mesh. Hybrid networks (They are the complex networks, which can be built of two or more topologies together). Bus Topology A bus topology is characterized by the use of a multi point medium. A long and single cable acts as a backbone to connect all the devices in a network. In a bus topology, all computers are stations attaching through the tap (an interfacing hardware to connect to the network) and it connects directly to the bus network. Datas are transmitting and receiving to the bus, by the duplex actions between the tap and the device. Devices in the bus topology send a broadcast message to the other device for communications. But the proposed device can only accepts and processes the messages. Advantages Bus topology can install very easily on a network. Cabling will be less compare to other topologies because of the main backbone cable laid efficiently in the network path. Bus topology suited for a small network. If one computer fails in the network, the other computers are not affected they will continue to work. It is also less expensive than star topology. Disadvantages The cable length will limited and there by limits the number of stations. The main cable (backbone cable) fails, and then the entire network will fail. It is very difficult to trouble shoot. Maintenance cost is very high in a long run. Terminators are required for both the ends of the cable. Ring topology The ring topology is the network consists of dedicated point to point connection and a set of repeaters in a closed loop. Signals passing through ring in a single direction until they reach to its final destination. It may be clock wise or anti clock wise. Datas are transmitted in the form of frames. These topologies are used in school campuses and some office buildings. Advantages It performs better than star topology under heavy work load For managing the connection between the computers, there is no need for the network server. It is cheaper than star topology because of less wiring. By adding the token ring in the network, can create large network. Very order network because all the devices has a access to the token ring and opportunity to transmit. Disadvantages A failure or break in the ring, it can disable the entire network. It is much slower than an Ethernet network with under normal load. Any moves, changes and ads of the devices can affect the network. Network connection devices like (Network adapter cards and MAU) are much more expense than Ethernet cards. Star Topology Star topology is the network in which each station is directly connected to a central connecting node called hub. In star topology all the devices are not directly connected to one another. All the devices are connecting to the central server (switching hub). This topology does not enable the direct traffic between the devices in the network. A controller act as the interface between the devices. A star topology feature, each device needs only one link and one input/output port to connect the number devices in the network. This type of topology is used in local area networks (LAN) and sometimes high speed LAN often uses a star topology with central hub. Advantages If anyone connection is fails in the network, it will not affect the entire network. Only that connection or link affected. It is easy to identify the fault and fault isolation. Easy to expand the network in the star topology. No failure to the network when connecting or removing devices. It is very easy to manage because of its simplicity in the function. Disadvantages In a star topology, if the central connecting device goes down, the entire network will fails. It requires more cable length compared to the linear bus topology. Star topology is more expensive than bus topology because o the connection ports like hub. Tree Topology Tree topology is the generalized form of the bus topology. It integrates the multiple star topologies together on to a bus. The data transmission of the tree topology, through the cables with closed loops. The transmission medium is a branching cable with no closed loops. The layout of the tree topology is beginning at the head end. These layouts have many branches and these are quite complex layouts in the topology. Any transmission from the device is going through the medium and it can receive by all other devices in the tree topology network. Tree Topology will give the expansion of the existing network. Advantages Tree topology is well supported by the hardware and software vendors. Point to point wiring for each and every segments of the network. It is the best topology for the branched networks. Disadvantages It is more expensive because more hubs are required to install the network. Tree topology is entirely depends upon the backbone line, if it fails then the entire network would fail. It is very difficult to configure and wire than other network topologies. In a tree topology, the length of network depends on the type of cable being used. Mesh Topology In a mesh topology, every device has connected to each other or a dedicated point to point link to every other device. (Dedicated term means that the traffic links only between the two devices it connects). To find the number of physical links in a fully connected mesh network with n nodes, we first consider that each node must be connected to other node. Node 1 must be connected to n-1nodes, node 2 must be connected to n-1nodes, and finally node n must be connected n-1 nodes. If each physical link in the network can allow the communication in both directions, we can divide the number of links by 2.In other words we can say that in a mesh topology, we need n (n-1)/2. Suppose if we are connecting 15 nodes in a mesh topology, then the number of cables required; CN = n (n-1)/2 CN = Number of cables = 15 (15 1)/2 n = Node = 15*14/2 = 15*7 = 105 Therefore, the total number of cables required for connecting 15 nodes = 105. Advantages There is no traffic problem because of the dedicated link in the mesh network. Mesh topology is very strong. If any link becomes not active it does not deactivate the entire system. Point-to-point links make full identification and fault isolation easy. Security or privacy for data travels along the dedicated line. Network can be expanded without any disruptions to the users. Disadvantages Installation and reconnection are difficult. Mesh topology required more cabling and the number input/output ports comparing with other network topologies. Sheer bulk of the wiring can be greater than the available space can accommodate. The hardware required to connect each link can be prohibitively expensive. Hybrid Topology A network can be hybrid, which uses two or more network topologies together in a network. An example of hybrid technology is the star ring network. OSI Model in the Network The OSI model was developed by the ISO (International Organization for Standardization) in 1947, as a model for a computer protocol architecture and as a frame work for developing protocol standards. The purpose of the OSI model is show how the communications are going through in a network between different systems. The OSI model is not a protocol; it is a model for understanding a network architecture .This model is flexible, very strong and interoperable. The OSI model is a layered frame work for the design of network systems that allows communication between all types of computer systems. OSI model contains of seven layers, each of which defines a part of the process moving information across a network. The OSI reference model has been divided into two categories according to their specific functions in the network architecture; upper layers and lower layers. The lower layers are used to allow traffic through the network to the other system. The other four layers are used to complete the process to the other system. The Advantages of the OSI model are given below It helps the user to understand the whole features involved in networking OSI model gives a better understanding to the users that how a software and hardware components working together in the networks. Troubleshooting in the OSI model is easier as it breaks the network into usable layers The basic functional relationship terms are defined so that it can be used by network professional on another network The users can understand new technologies as they develop in this model Upper Layers of the OSI Models are; Application layer Presentation layer Session layer The upper layers have act as an interface between the end user and the applications. It consists of all the issues about the application, presentation and sessions and these layers are applied in software only. The application layer is more close to the end user. Examples of upper layer technologies in the OSI model are SNMP, FTP, and WWW etc. Lower Layers of the OSI Model Transport Layer Network Layer Data link Layer Physical Layer These layers provide network specific functions like data transport issues (flow control, addressing and routing). The bottom layers in the OSI model (physical layer and data link layer) can use in software and hardware also. TCP, UDP, IP, IPX are some examples for the lower layers. Application layer The application layer act as the interface to the end users can access the network. Application layer is the layer the user sees in contest of loading an application such as e-mail, supporting the file transfer, ability to print on a network, surfing the World Wide Web etc. These layer have another specific functions like network virtual terminal, access and management, mail services and directory services. Protocols used in this layer are SMTP, Telnet, FTP, and SNMP. Presentation layer In the presentation layer, the application formats the data to be sent out on the network depending on the presentation layer. The presentation allows applications to read and understand the data or message sent.The presentation layer is also responsible for the translation, compression and encryption. Messages are sending between the layers. Presentation layer will translate data into understandable for the transmission. This layer also handles the encryption, decryption, data compression and decompression. Session layer The session layer is the network dialog controller. It establishes, maintains and synchronizes the interaction among communicating systems. This layer is responsible for opening, using and closing session. It handles the remote procedure calls. Session layers are communication through the gateways and application interfaces. Session layer will also places check points in the data flow. Examples for the session layer are SQL, ASP, and RPC etc. Transport layer The transport layer offers end to end communication between the two end networks devices in a network. The transport layer is also responsible for the delivery of a message from one process to another. A process is an application program running on a host. The transport layer ensures that the whole message arrives intact and in order, overseeing both error control and flow control at the source-to-destination level. Transport layer gives a type of address to the data called port address. Transport layer also have the responsibilities of detecting transmission error and the proper sequence. This layer divides the messages into smaller packets and it controls the data flow. Network layer A Network layer provides the end to end (source to destination) delivery of a packet, across the multiple networks (links). This layer ensures that each packet gets from its point of origin to its final destination. Network layer gives logical addressing, so that endpoint (receiver) can be identified. During a packet delivery process it send messages and report errors. This layer also defines the routing works and how routers can learn how a packet can deliver. Examples for network layer protocols are IP, IPX, and TCMP etc. Data link layer A Data link layer transforms the physical layer, a raw transmission facility, to a reliable link. It makes the physical layer appear error-free to the upper layer. This layer divides the datas into frames and gives the physical address. It uses the MAC address for define a hardware or data link address .Data link layer handles the flow control, error control and the access control. This layer can identify the specific computer on the network. Data link layer contains two sub layers; Logical Link Control and Medium Access Control. LLC is the upper layer and which maintain and establish the communication links to the device. And it also responsible for the frame error control and addressing.MAC is the lower sub layer of the data link layer. It controls how the devices sharing the media channel. Physical layer A Physical layer is used to define the connector and interface conditions, also the medium requirements which are cables. The Electrical, Mechanical, Procedural and Functional conditions are also defined by sending a bit stream on the network. This layer defines the characteristics and different types of medium. Physical layer defines the data rate i.e. the duration of a bit or how long they will exist. Physical layer will tell the transmission mode between two devices.
