Walmart :: essays research papers
In 1945, Sam Walton opened his first variety store and in 1962, he opened his first Wal-Mart Discount City in Rogers, Arkansas. Now, Wal-Mart is expected to exceed ââ¬Å"$200 billion a year in sales by 2002 (with current figures of) more than 100 million shoppers a weekâ⬠¦(and as of 1999) it became the first (private-sector) company in the world to have more than one million employees.â⬠Why? One reason is that Wal-Mart has continued ââ¬Å"to lead the way in adopting cutting-edge technology to track how people shop, and to buy and deliver goods more efficiently and cheaply than any other rival.â⬠Many examples exist throughout Wal-Martââ¬â¢s history including its use of networks, satellite communication, UPC/barcode adoption and more. Much of the technology that was utilized helped Sam Walton more efficiently track what he originally noted on yellow legal pads. From the very beginning, he wanted to know what the customers purchased, what inventory was selling and what stock was not selling. Wal-Mart now ââ¬Å"tracks on an almost instantaneous basis the ordering, shipment, and delivery of literally every item it sells, and that it requires its suppliers to hook into the system, enabling it to track most goods every step of the way from the time theyââ¬â¢re made and packaged in the factories to when theyââ¬â¢re carried out store doors by shoppers.â⬠ââ¬Å"Wal-Mart operates the worldââ¬â¢s most powerful corporate computing system, with a capacity (as of late 1999) of more than 100 terabytes of data (A terabyte is 1,000 gigabytes, or roughly the equivalent of 250 million pages of text.). Only the U.S. government maintains a bigger database.â⬠Sam Walton was eventually considered ââ¬Å"the most influential retailer of the century, and with good reason, for nearly every great retailer of the coming years would follow his business examples.â⬠Industrial Revolution: When the Industrial Revolution took place in the United S tates, factories were now able to out produce consumer demand. For the first time, these new goods needed new ways to be sold, new ways to get to the public. ââ¬Å"In New York, Philadelphia, and Chicago, the first department stores opened their doors. Railroads and telegraph wires snaked across the country, giving storekeepers a new way to order goods and get them on the shelves faster than ever before. A whole new industry sprang up to persuade people through advertisements with enticing pictures and clever slogans, to buy things theyââ¬â¢d never known they needed, to turn America, in the phrase department store pioneer John Wanamaker, into the Land of Desire.

Difficulties Interracial Couples Experience
I see interracial couples all the time facing unique struggles and lacking support from family, friends and multiple others. Having knowledge of the reasoning behind this lack of acceptance will help one form a greater understanding that may enable an individual to adjust the judgmental difficulties that they are faced with in an interracial union. The interactions with people that mixed couples experience can be viewed as symbolic interactions because the gestures and words that are interpreted often in negative ways can contribute to the difficulties faced.People deal with racial struggles all over the world. Different countries experience a greater degree of struggles than others. Since Canada is a multicultural country, one might assume that interracial couples would be more accepted and faced with less racial struggles. Unfortunately, that is not the case; couples are still ridiculed. In present day, it's true that interracial couples are more accepted now than years previous bu t support of exogamy is still low. A mere fifty years earlier, the thought of a mixed union was a taboo. During the era of segregation, a mixed union between an AfricanCanadian and a Caucasian person was unthinkable. The federal government in Canada has a history of polices that have attempted to separate races from joining in relationships. A vivid example of Canada's attempt to control and prevent interracial intimacies is the Indian Act. ââ¬Å"The Indian Act, with all its variations, clearly restricted and provided penalties for interracial sex and marriages. â⬠(Real Canadian History, 2012) Some of the discrimination that mixed couples receive today, from individuals has been passed through the previous generations.Though, as generations become more educated they re likely to be more opened minded. The history of views on interracial relationships has contributed to the lacking acceptance experienced in present day. There is no one definitive answer as to why there is hatr ed toward mixed unions, what does exist in the scholar world are a few general statements that provide some understanding. Most Of the problems that interracial couples face relate to racism, discrimination and prejudice. Today's ââ¬Å"young people, who have went to college are educated and more commonly opened-minded. (Bridge News, 2007) This generation is commonly the population participating in interracial unions and they are often more accepting. ââ¬Å"Their parents however, are not as educated and are still strong believers of sticking to your own race. â⬠(Bridge News, 2007) This is a reason why some parents disapprove of mixed relationships. Parent's opinions are often very important to their children. Stereotypes about different races can also influence the views that a parent could have regarding an interracial union that their child is apart of. Prejudice often results from the mismatch between beliefs about the attributes typically possessed by members of a social group (that is, their stereotype) and beliefs about the attributes that facilitate success in valued social rolesâ⬠(On the Nature of Prejudice, p. 19). Similarly, ââ¬Å"[On the Nature of Nature of Prejudice] argue[s] that the potential for prejudice exists when social perceivers hold a stereotype about a social group that is inconsistent with the attributes that are believed to be required for success in certain classes of social rolesâ⬠(p. 3). Parents are non-accepting when such perceived stereotypes are negative. Jon K. Mills at Vanderbilt University did an investigation Of a group with 142 undergraduates on the receptions of family acceptance concerning interracial relationships. Mills concluded, ââ¬Å"both Black and White students indicated that family perception of these interracial relationships would be negativeâ⬠(Family Acceptance Involving Interracial Friendships, p. 349). The most common question that is asked of mixed couples is ââ¬Å"what do your par ents think of your relationship?This is more evidence that parental disapproval is a common difficulty that mixed couples endure. ââ¬Å"Hate still looms as aforementioned because of the inherent survival mechanism that many racial groups want. It is a form of protection almost. â⬠(Lotus, 201 3) Parents have a hard time accepting or even considering the idea of having a grandchild that is mixed with another race different from their own. ââ¬Å"Ezekiel (1995) argues that racists often fear their own survival as a group and hate gives them comfort and assurance that their survival will be met or achieved. Another common issue in mixed unions is the joining of different religions and different cultures. Couples are usually supportive of each other's beliefs but often run into problems. Some religions pacifically disagree with marrying outside of the said religion. More generally couples run into issues such as dietary restrictions. As an example, practicing Muslims do not eat po rk and all of their meat must be hall. Different religions lead to different holidays, which can keep couples wondering which traditions they Will pass onto their kids.Interracial couples are ridiculed often because of the difficulties they will pass onto their children. ââ¬Å"In October 2009, a Louisiana Justice of Peace refused to perform a marriage for a mixed-race couple because he was concerned with the rejection and confusion their hillier would experience growing upâ⬠(Curry, 2010). Some mixed couples decide not to have children because they do not want their children to go through the things they have experienced and to avoid the difficult decisions of which traditions to pass forward.This is another contributor to why individuals do not accept interracial couples and it is also a difficulty regarding important decisions that mixed couples must make. A lot of research regarding interracial couples reveals that such couples face difficulties that are often due to family opinions. There are multiple reasons why families, specifically parents, do not accept mixed unions. Such reasons have been elaborated on and it has been expressed that parental opinions are often a large influence in one's life.When parents have negative views on mixed relationships, it places a burden upon children participating in such relationships. It is true that other factors such as religious and culture differences, give difficult problems to mixed couples as well; such factors are not always as detrimental because they are outweighed by the benefits they receive in the relationship. Research on mixed relationships also revealed any unknown benefits of these relationships.

The Media and How it is Killing Americaââ¬â¢s Future Essay
The Media and How it is Killing Americaââ¬â¢s Future They grace the cover of magazines everywhere we look. Their beautiful tanned skin engulfs a slender ââ¬Å"perfectâ⬠body. The men and women of Hollywood truly are striking, but also all look very much the same. There is an obvious trend in these magazines and on television that thin is in, and only skinny people are worthy of adorning magazine covers. Does this mean that only the thin are beautiful in todayââ¬â¢s society? Whether they mean to or not, the media definitely indicates that this is the case, leaving a very unrealistic image of what is attractive in the minds of young people. Therefore, it really shouldnââ¬â¢t come as any surprise that eating disorders are becoming more andâ⬠¦show more contentâ⬠¦The fact is, one in three adolescent girls has suffered or is suffering from some form of an eating disorder, from severe dieting or excessive exercise, to actual starvation (Steinhausen, 95), and six out of ten high school girls diet, along with one in fo ur high school boys (Berg, 17). These percentages are ridiculously high, and show that there is definitely a problem in our society. Eating disorders are extremely serious and often even fatal. They are tremendously trying on both the person with the disorder, and those who are close to them. I remember the time that my roommate and I were watching TV with a group of girls when one of the girls started commenting on how fat a certain actress had become, and how gross she looked. I saw the look on my roommateââ¬â¢s face when she heard this girl criticize this actress who still looked practically perfect. More than anything, the weight this actress had put on made her look healthier than she had before. I became quite concerned though when I noticed that my roommate ate nothing for the next three days, and the one meal she did eat I am certain she threw up soon after. My roommate, like many other girls, was trying to achieve an unattainable goal. Some girls will just never be so thin, and struggling to be is very dangerous.

Is Use Of Corporal Punishment Nessecary - Free Essay Example
Sample details Pages: 4 Words: 1228 Downloads: 4 Date added: 2019/07/30 Category Society Essay Level High school Tags: Corporal Punishment Essay Did you like this example? Is the use of corporal punishment against 3-year old children associated with future aggressiveness among them? This question brings about a controversial topic on whether it is ok to spank children because of the underlining negative effects it could have on childs behavior in the future. Many parents when disciplining their children use corporal punishment (CP), which includes spanking or slapping, to teach their children lessons, imprint values, and improve current or future behavior. Whether this form of discipline creates future aggressive behavior is the question The American Academy of Pediatrics asks as they conduct a study to see the effects CP has on 3-year olds future development of aggressive behavior. Donââ¬â¢t waste time! Our writers will create an original "Is Use Of Corporal Punishment Nessecary?" essay for you Create order During this experiment, the American Academy of Pediatrics states that their goal is to be able to answer whether there is a link between a mothers use of corporal punishment on a 3 year old and the risk for that child to become more aggressive at age 5, even with the control of the childs initial level of aggression at age 3 and other important maternal parenting risk factors and demographic features (Taylor, Manganello, Lee, Rice, 2010). Before the study is conducted, The American Association of Pediatrics creates a single hypothesis that states that dozens of studies have shown a significant statistical link between the use of CP with children and child aggression (Taylor, Manganello, Lee, Rice, 2010). This includes studies that also controlled the childs initial aggression level. This proposed explanation creates the basis of what they already know on this subject and helps to build on this idea by adding other important maternal parenting risk factors and demographic features. To conduct this study, they choose a sample from the Fragile Families and Wellbeing study (FFCWS). They then ran 2 interviews, one at the childs age of 3 and the other when the child reached age 5. The mothers were questioned from the 19 items from the Child Behavior Checklist version for age 3. This asked certain questions such as if their children at age 3 were defiant, disobedient, easily frustrated, screams a lot, hits others or gets in reoccurring fights, or had irritable tempers. This was measured to determine whether if the aggressive behavior stemmed directly from CP or other factors. At age 5 the children were assessed from the 12 items from the Child Behavior Checklist that included behaviors such as bulling or meanness to others, destructiveness of things belonging to family members or others, arguing a lot, and threats to others. This type of study incorporated more than one study design. The first study design that it incorporates is observational study this study is whe re conclusions, are drawn from a sample, in this case the Fragile Families and Wellbeing study, to a population where the independent variable is not under the control of the researcher because of ethical concerns or logistical constraints. This is used to keep the study ethical by observing rather than assigning manipulation. Another study design that was used was survey study. This design is used to gather information from large groups in order to have more accurate results. The manipulation of this study design is used in the way the study is conducted through questionnaires of the parents of the children at ages 3 and 5. The next study design that was implemented was longitudinal study. This type of study is conducted over a long period of time to see the development of an issue over a timespan.à This design had to be used to measure the behavior between the ages from 3 to 5. The last study design that was used was retrospective study. This is where past behavior/data is view ed to study past vs. present. This is implemented by comparing the childs past behavior at age 3 with their future behavior at age 5. In order to conduct this study 2 groups must be involved, the experimental group and the control group. The experimental group is these studies were the children who did not receive corporal punishment and the control group were the children who received corporal punishment. It also must also include a independent or predictor variable and a dependent or outcome variable. The independent or predictor variable is the variable that is being manipulated to see its effect on the dependent variable or outcome variable. So therefore in this study corporal punishment is the independent variable and subsequent aggressive behavior in 3-year olds is the dependent or outcome variable. All 3 of these design studies contribute to the accuracy and correlation between variables. Through this study we see that even with the control of the childs initial level of aggression at age 3 and the preceding potential confounding factors and key demographic features, Frequent use of corporal punishment, where the mothers use of spanking was more than twice in the previous month, is directly associated with increased subsequent aggressive behavior when the child reaches age 5(Taylor, Manganello, Lee, Rice, 2010). From the results of this study we can also see the findings support a social learning approach to understanding the cycle of violence. This is where the child learns to be aggressive by being treated undeviatingly with aggression. From this study and its results, we can conclude that regardless of the American Academy of Pediatrics recommendation to not use corporal punishment, many parents will continue to use this form of discipline contrary to the behavioral effects children may face. It is even shown that minor forms of CP can increase risk of subsequent aggressive behavior. By using this modern information, we can single handedly stop the increase of violence in our future generation. Also, Mothers and future mothers can take this information in to account for when they raise their children and the methods of discipline they will choose in order to correctly imprint lessons and values without the risks of potentially negatively effecting the behavior of their child to be aggressive. The American Academy of pediatrics recommends the use of other effective and less risky discipline strategies instead of the use of CP. While conducting this study the researchers did however encounter confounds and limitations to their data. These include the studies focus only on the mothers use of CP and not fathers or other caregivers and the design type that was choose for this study that relies on the honesty of the mothers self-report. Although this design type creates limitations to the study, it is what makes this study ethical. By using observational studies instead of experimental studies is what makes this study ethical and able to be performed and approved by the IRB. This is because unlike in experimental studies where you would have to manipulate and spank the child that could potentially harm the child and create long term effects to receive data, observational studies are used to observe behavior without manipulation. This study is also ethical because it follows the IRB regulation and laws by having the approval of the parents since children are considered to be in the sensitive group where extra pr otection is needed since the children are cognitively unable to give consent. Also, the information received from the mothers are self-reports, so they are voluntary and free from coercion. The American Academy of Pediatrics precisely conducts this study which is why so many people have cited this article and journal publisher the past couple of years with an impact factor of 5.515, which is the highest impact factor of the other 124 pediatric journals in the 2018 Citation Report.

Quine Writes s Two Dogmas Of Empiricism - 1691 Words
Elisabeth Daigle Massey Contemporary Philosophy 8 December 2015 Contemp. PHL Paper Draft Quine writes ââ¬Å"Two Dogmas of Empiricismâ⬠critiquing two parts of empiricism separate from the rest of what empiricism entails. These two dogmas are: a) there is a principled distinction between analytic and synthetic propositions, and b) reductionism is true. Quine also explains undetermination and its uses. His application is that anyone can believe anything if they are willing to let go of some background knowledge which could refute it. Commonly said as, believe x, come what may. Laudan has set out to demystify underdetermination because Quineââ¬â¢s use has been oversimplified and misused by many. It will be helpful to first define dogmas, reductionismâ⬠¦show more contentâ⬠¦One of the dogmas that Quine addresses is ââ¬Å"reductionism.â⬠Reductionism refers to the empiricist claim that the meaning of a proposition is its verification conditions. The belief that each statement is equivalent to some logical construct upon terms which refer to immediate exp erience, observations. Underdetermination is the thesis explaining that for any scientifically based theory there will always be at least one rival theory that is also supported by the evidence given, and that that theory can also be logically maintained in the face of any new evidence. This theory allows for conflicting things to coexist, they might be consistent by they are not necessarily rational. The Quine-Duhem thesis involves the idea that a ââ¬Å"physicist can never subject an isolated hypothesis to experimental tests, but only a whole group of hypotheses.â⬠This is to say that when an experiment is conducted and fails, the conductor cannot say I will test ââ¬Å"xâ⬠and prove that ââ¬Å"it was x that was in disagreementâ⬠because all he knows is that at least one variable, one hypotheses, in the group is unacceptable and therefore must be changed. The experiment does not flag the culprit, the reason the whole failed. Instead the entire hypothesis is put int o question and can, in itââ¬â¢s entirety be tried again. This would seem to be analogous, though on its face it is not clearly analogous, to all theories and hypotheses, not just

All of these are false ââ¬â and true, or at least a nugget of truth is in them. In order for us to understand their factual basis, we must first make some distinctions, because not all bilinguals are the same! Factors or dimensions in bilingualism and SLA: * Sequential vs. Simultaneous Acquisition * Compound vs. Coordinate Input * Dominant vs. Balanced Bilingualism * Contextualized vs. Decontextualized language use for L1 and L2 Truth behind the myths Linguistic Confusion ââ¬â this occurs only for simultaneous acquisition, and only for a few months early in the life of a child. It is not a large degree of confusion, and it quickly is overcome (and some researchers propose that it is never really confusing at any stage of acquisition). L1 takes away L2 ââ¬â this is only true in the sense that INPUT MATTERS, and the amount of input of L2 is important ââ¬â how much L1 is not important. However, the better foundation of L1, the easier time people have getting into L2, at least in the early stages of L2 acquisition in terms of oral language.

Levels of Second Language Proficiency BICS and CALP ( http://www. iteachilearn. com/cummins/bicscalp. html ) Basic Interpersonal Communication Skills (BICS) is a level of second language proficiency that can be acquired within 1-2 years of immersion or exposure. ââ¬Å"It is the day-to-day language needed to interact socially with other people. English language learners (ELLs) employ BIC skills when they are on the playground, in the lunch room, on the school bus, at parties, playing sports and talking on the telephone. Social interactions are usually context embedded. They occur in a meaningful social context. They are not very demanding cognitively. The language required is not specialized. These language skills usually develop within six months to two years after arrival in the U. S. â⬠Judy Haynes, retrieved May 4, 2010, www. everythingESL. net Cognitive Academic Language Proficiency (CALP), on the other hand, is a level of second language proficiency that requires more specialized grammar, vocabulary, and language use ââ¬â for literacy, reasoning, school work and academic conversations. It can take up to 5-7 years of immersion and exposure ââ¬â 7-10 years if the child does not have previous experience in school or using their first language in academic/cognitive contexts and activities. - Cognitive Balanced bilinguals, especially those using both languages for decontextualized language uses, have cognitive benefits: Earlier metalinguistic awareness * Earlier executive functions * Earlier creativity ââ¬â divergent thinking Otherwise, Dominant bilinguals appear to have no advantage or disadvantage over monolinguals.

Internet1 Essay Example For Students
Internet1 Essay Beam me up, Scottie. This popular line from Star Trek was a demonstration of the advanced technology of the future. Though it was a fictional story, Star Trek became the universal vision of the future. As always reality tends to mimic fiction. Though our society has not quite resulted to living in space, we have made life easier with technology. Economic survival has become more dependent upon information and communications bringing forth new technology of which was never thought possible. Just a mere thirty years ago a computer occupied a whole room compared todays palm sized computers, which are faster and perform more functions. Cellular phones, now light and compact, were bulky just ten years ago. The most incredible invention, the Internet, is bringing infinite amount of information to your desktop. In the world of the of the Internet there exist a world blind to skin color and other physical appearances. The Internet while still young in age has grown rapidly, spreading to coun tries world wide and connecting 50 million users. With its popularity, it is incumbent upon our society to recognize how the Internet works and to be aware of its advantages as well as disadvantages. While seemingly high tech the Internet concept is rather simple. Computers speak to one another and send information. This is accomplished by sending and receiving electronic impulse, and then decoding them into a message. In order to communicate with one another they are linked up in a network. They are then able to access information from thousands of other computers. The network acts like one large computer storing information in various places, rather than in one physical structure. Users tap into the Internet to access or provide information. Internet technology allows one to surf the World Wide Web or send e-mail. The vision of the Internet that would revolutionize the computer and communications belonged to JCR Licklider of MIT (Leiner n. page). In August of 1962 he envisioned a globally interconnected set of computers which would allow everyone to quickly access data and programs (Leiner n. page). A government sponsored project at Defense Advanced Research Projects Agency (DA RPA) started in October (Leiner n. page). The race for discovery of such technology raged between the Soviet Union and The United States of America. Both countries wanted control of the possibly powerful tool. Then in 1968, The National Physical Laboratory in Great Britain set up the first test network, which prompted the Pentagons ARPA to fund a larger project in the USA. (Sterling n. page)However the race was not limited to just nations but also companies. In 1965, working with Thomas Merrill, Lawrence G. Roberts created the first wide-area computer ever built. These experiments proved that computers could work together running programs and retrieving data as necessary on remote machines. Roberts put together his plan for ARPANET, published in 1966. At that time he learned of Donald Davies and Roger Scantlebury of NPL and Paul Baron and others at RAND. Research at MIT (1961-1967), RAND (1962-1965) and NPL (1964-1967) while parallel had no knowledge of one another. In August of 196 8 an RFQ, a refined model of ARPANET was released for the development of one of the key components, the packet switches Interface Message Processors (IMP). Bolt Beranek and Newman (BBN) installed the first IMP at UCLA and the first host computer was connected. By the end of 1969 four host computers were connected together into the initial ARPANET and the Internet was off the ground. In 1977, electronic mail was introduced. (Leiner n. page)As the Internet quickly grew, changes were necessary. The Internets decentralized structure made it easy to expand but its NCP did not have the ability to address networks further down stream than the destination IMP. Bob Kahn decided to develop a new version of the protocol which eventually became known as the Transmission Control Protocol / Internet Protocol (TCP/IP). Compared to the NCP which acted as a device driver, the new protocol was more like a communication protocol. In order to make it easier to use, Host were then assigned names, replac ing numbers. A group of scientist then set out to show that a compact and simple implementation of TCP was possible. They succeeded, allowing it to run on desktop computers. (Leiner n. page). Original uses of the Internet included government communications and a forum for scientist to share ideas and help one another in research. In the 1980s the Internet grew beyond its primarily research roots to include a broad user community and increased commercial activity. In present day it has become a tool for conducting research and finding information, as well as communications with others. Electronic mail, amazingly popular, with chat rooms and discussion groups makes the Internet a popular place for meeting new people. (Leiner n. page). Macbeth: Describe Macbeth As A Tragic Hero EssayHowever, the Internet being so free and uncensored presents many problems. Acknowledgment of children using the Internet has fueled a fight for regulation. Parents can not always monitor their children, therefore the Internet needs to be a safe place for the children. Children have access to the Internet in schools, libraries, and just about everywhere. In schools it is nearly impossible for a teacher to watch all the children, and in libraries it is not the librarians job to monitor them. Computers and the Internet are for everyone, including children, thus it has become an immense problem. Access to pornography has been one of the greatest concerns among parents. Surprisingly, pornography is easy to access and children will. Children are naturally curious and love to explore. Minors are also targeted by advertisers. Just like on television advertisers try to lure children in with pictures and web sites which include games and chat rooms. However the biggest danger is not what they find on the Internet but who they find. The information they access is not as dangerous as the people they meet. There have been many cases of molesters and kidnappers searching for pray on-line. Nicknames are used to protect the identity of the children but can also be used to mask adults. They enter childrens chat rooms and coax the children to trust them. Nonetheless, denying the children access to the Internet is not the solution, perhaps software is. However software limiting childrens access to web pages have not been successful. In some case the software does not filter out all inappro priate pages but filters out non-objectionable pages. (Should children be kept off-line? n.page)Molesters and kidnappers are not the only people with access to the Internet we should fear. Those mischievous thinkers also pose a threat. Known as hackers or crackers, they search for vulnerable computer systems then strike. Businesses can lose trade secrets, and the damages can be a disaster. In 1996 Dan Framer, a security consultant, tested 2,000 computers networks, and of those 65% had security holes large enough for an intruder to enter (Freedman 280). Government computers are just a vulnerable as teenagers have recently demonstrated. Teenagers working out of their home with guidance from a 18 year old broke into government classified information. Though they were caught, it bought alarm to the possible dangers of information leaks. The United States enemies could have access to military codes and top secret files. Although the average person is not targeted by hackers they are in danger of fraud and con-artists. Stolen credit card numbers have been rumored to be a major problem. The chances of it happening are not as great as the media makes it to be, but nevertheless it is a problem. The criminals easily get away with such a crime. They get the number of a credit card and charge ridiculous bills, but by the time the bill comes they have moved on to the next victim. Many schemes come in the form of junk mail. They offer deals that sound too good to be true and chances are they fake. They only ask for a small sum of money up front, next they cash the check and move on. ( Anarchy Online 98)Secure passwords can prevent hackers from accessing computers. Passwords should consist of numbers, letters and symbols: an example P11++69. No matter how secure and high tech the computer security system, all it takes is a simple , stupid password like hello to render the whole system worthless. (Freedman 279 )Though the Internet has its advantages it also has disadvantages, therefore users should educate oneself on the revolutionary tool. With over 50 million users the Internet is rapidly growing and is to the 90s what the personal computer was to the 70s. New usages are springing up everyday, making it impossible to predict the future of the Internet. One thing certain is that the Internet has revolutionized the computer and communications. The Internet is a world wide broadcasting capability, a mechanism for collaboration and interaction between individuals without regard to geographic location. (Leiner n.page)Bibliography:
