Network Infrastructure For E Commerce Information Technology Essay

Network Infrastructure For E Commerce Information Technology Essay   E-commerce or eCommerce is basically Electronic commerce that deals with buying and selling of services and products over electronic systems such as Internet and other Computer networks. E-commerce is commonly known as electronic marketing. With the extensive use of Internet, the amount of trade carried out electronically has developed tremendously. E-commerce (electronic commerce or EC) is the buying and selling of goods and services on the Internet, especially the World Wide Web. In practice, this term and a newer term,  e-business, are often used interchangeably. For online retail selling, the term  e-tailing  is sometimes used. Electronic commerce is generally considered to be the sales aspect of e-business. It also consists of the exchange of data to facilitate the financing and payment aspects of the business transactions. REQUIREMENTS FOR E-COMMERCE: Authentication PrivacyMessage Integrity Non-repudiation NETWORK INFRASTRUCTURE FOR E-COMMERCE: Global information distribution networks are the infrastructure that are connecting countries and continents. Extranets, Intranets and the Internet, the above parties are spread over diverse locations, extranets use the internet as a network to reach out to these parties. A company typically has multiple dedicated extranets for different parties depending on information needs and nature of relationship. Extranets can sometimes also be seen as an extension of the company intranet or internal network where external parties are brought into the fold of the companys private network with access to specific areas or information. Internet This is  the world-wide network  of computers accessible to anyone who knows their Internet Protocol (IP) address the IP address is a unique set of numbers (such as 209.33.27.100) that defines the computers location. Intranet This is a network that is not available to the world outside of the Intranet. If the Intranet network is connected to the Internet, the Intranet will reside behind a firewall and, if it allows access from the Internet, will be an Extranet. The firewall helps to control access between the Intranet and Internet to permit access to the Intranet only to people who are members of the same company or organisation.   Extranet An Extranet is actually an Intranet that is partially accessible to authorised outsiders. The actual server (the computer that serves up the web pages) will reside behind a firewall. The firewall helps to control access between the Intranet and Internet permitting access to the Intranet only to people who are suitably authorised.   EXTRANET: An extranet is a private network that uses Internet protocols and the public telecommunication system to securely share part of a businesss information or operations with suppliers, vendors, partners, customers, or other businesses. An extranet can be viewed as part of a companys Intranet that is extended to users outside the company. The same benefits that Web technologies have brought to corporate Intranets are now starting to accelerate business between businesses. Extranets can be used to exchange large volumes of data, share product catalogues, share news with trading partners, collaborate with other companies on joint development efforts, jointly develop and share training programs with other companies, provide or access applications between companies, and much more. It may sound like a technology for geeks only. But many people use extranets every day without realizing itto track packaged goods, order products from their suppliers or access customer assistance from other companies. An extranet is a mechanism based on Internet and Web technology for communicating both privately and selectively with your customers and business partners. USES OF EXTRANET: When done correctly, extranets provide a safe way to allow transactional business-to-business activities and can save your company some serious time and money. The automotive industry uses extranets to cut down on its redundant ordering processes and keep suppliers up to date on parts and design changes, allowing quicker response times to suppliers problems and questions. Suppliers can receive proposals, submit bids, provide documents, even collect payments through an extranet site. An extranet has restricted (password-protected) access, so it may be connected directly to each partys internal systems. DISADVANTAGES: The benefits of extranets, such as reduced time to market and cost of doing business, and faster access to partner information, may be outweighed by the costs-security, Web servers and development, legacy systems integration, ongoing support and maintenance. Extranets require a large amount of IS time and energy, much more than what it takes to get an intranet or Web site up and running, which may place it at the bottom of the IS groups to-do list. CONCLUSION: A mix of each is most likely, Connect to partners, suppliers, customers in the best way that supports your specific business model. extranet is helpful conversationally when considering giving external parties access to enterprise systems. The term should engender a deeper level of consideration and concern regarding maintaining security and managing external relationships.

Friendship and Facebook Essay

Facebook started out as a simple social networking site, and has now grown to be one of the biggest companies in the world. One would typically join the site to be social with others, but it seems like it is almost distancing people from one another. Facebook users tend to have hundreds of friends, but how many of those can actually be considered real friends? The meaning of friendship seems to be forgotten when it comes to Facebook. Facebook is affecting friendship in society today because people use it too much, have too many â€Å"friends†, and do not put as much effort in to their â€Å"real life† friends. The idea of Facebook seems like it would be a great way to maintain social relationships, but because people are using it so much it is actually isolating them more than anything. If Facebook was used in moderation, it would probably bring people a lot closer than it does now. Many of the millions of people that have a Facebook tend to check their page multiple times a day. It has become a new addiction for people, and for some, a very serious addiction. Many people today can spend countless hours accessing the site, even when they are out in public! When out in a social situation, take a look around the room and notice how many people are glued to their phones. It’s absolutely absurd. Before the use of smartphones and Facebook, people actually socialized with one another when they were together. Now it seems like people are letting it take over their lives, and not looking around to see what’s going on right in front of them in the real world. Friends don’t spend as much time together because they are too busy tagging each other, or looking at the other’s comments or pictures. If people used Facebook less, it would have a more positive effect on friendship. Most people in the world do not have hundreds or even thousands of friends, but on Facebook that is the norm. It has almost become like a popularity contest to see how many friends one can acquire. The more people one becomes friends with the harder it is to stay in touch with all of them. By having all of these â€Å"friends†, it seems like people aren’t focusing on what it means to really be a true friend. Junghyun Kim and Jong-Eun Roselyn Lee did a study on the effects of the number of Facebook friends one has: Having too many Facebook friends, on the other hand, will not necessarily increase social support one can receive, for most of the ‘friendships’ may be superficial at best. It takes much time and effort to build and maintain mutual companionship with friends. Given the average number of close offline friends is only nine, it is not surprising that Facebook users maintain close connections with less than 3% of their Facebook friends. It is likely that the larger one’s Facebook network becomes, the less time and effort can be invested in each individual (Kim and Lee). People shouldn’t refer to Facebook friends as â€Å"friends†, because most of the time those people aren’t true friends. A friend is someone who is always there, and is an important person in life that is trustworthy. It seems like people today are more focused on commenting on someone’s post, rather than actually taking the time to spend time with them. People need to take the time to realize who their true friends are, and try to make sure they stay close with them. Facebook actually has a maximum number of friends one can have at a time. Amy Dempsey stated â€Å"Holding on to old friendships via Facebook may prevent us from forming new connections in the real world† (Dempsey). Amy later goes on to quote Oxford University professor Robin Dunbar, â€Å"According to Facebook, the reason for the 5,000-friend cap is that anything beyond that can make it too difficult to maintain an environment where you can stay engaged with your friends in a meaningful way†(Dunbar). It seems like the quality of friendship is diminishing in this society. People do not have the time to keep in touch with hundreds of people and actually have a close relationship with all of them. It shouldn’t matter how many friends one has, the quality of the friendship is much more important. Since people are using this site so much, their important relationships are suffering. Facebook may seem like it is bringing friends closer together, but it is actually just doing the opposite of that. Facebook is becoming detrimental to friendships because people are using it too much, are acquiring too many friends, and therefore are letting it affect their meaningful friendships. Life is so short, and people should take the time to appreciate their true friends who are right in front of them, rather than to try to keep in touch with people that they may barely even know. If Facebook keeps on growing and continuing the way that it is, it does not look too good for meaningful friendships. It really is simple, spend more time with friends and less time on Facebook.

Demography and Stable Fertility Replacement

A century is quite long; anything and many things could change in 100 years. Our world population and fertility rates for one thing. Currently developed countries either have a declining population or a mostly stable fertility replacement level. However, most developing countries still have an ever-increasing population, which has quite a few negative effects on health, economy, etc. Will they stabilize in the next hundred years? I believe there is a huge possibility for them to indeed stabilize.With an ever-increasing global village, thanks to social networks, different people in different countries are becoming more and more like-minded. These developing countries have more access to the media and the over all mind sets of developed countries. I am originally from Arizona in the USA, but have been living in South Africa for the past 4 years. I can sense a dramatic change between the thought patterns among older generations of this country and those of the youth.Even those living in the impoverished townships have complete access to current Hollywood movies, Internet, and current music. This access allows all of them to speak English along with think with a more westernized mindset. Where the older generations want as many children as possible so that their children will take care of them in old age, and because of lobola (where a potential husband must pay his fiance’s parents roughly $5000 to marry her).But the youth nowadays want to get secondary educations, and want to have smaller healthy families, because they desire to be more like Americans. If such access is available in other developing countries I believe they will have a more stable fertility rate at some point in the next 100 years. These governments however will need to have active policies. It is no use knowing you need contraceptives, when you cannot get contraceptives. Without the support of governments and health facilities, woman and couples just may give up trying to plan their child ren.While keeping independence in tact, governments need to have simple policies that allow for choice. Basically just giving the availability of contraceptives, family planning, and health facilities (some forced things could be sexual education in school). Freedom of choice should not be taken from them; rather policies to increase their choices so they can better take control of their individual lives and that of their families or planned family.

Anna Karenina, Death Foretold essays

Anna Karenina, Death Foretold essays The Understanding of Characters Through Relationships Relationships create strong holds in novels. They give a sense of what to base a character's acts and decision's on. Through how the author uses their tone and descriptions, relating to relationships, a sense of characterization can be developed. "Anna Karenina", by Leo Tolstoy, translated by Joel Carmichael, and "Chronicle of a Death Foretold", by Gabriel Garcia Marquez, translated by Gregory Rabassa, are no exception to this clause. Relationships form throughout these novels, by incorporating literary elements like characterization romanticism and realism, giving characters a sense of who they are, and the reader a sense of their role and reference to the story. In "Anna Karenina", relationships are built throughout the story helping for the reader to understand characters and who they are. One of the two major relationships taking place in the novel is between Anna Karenina and Levin. Anna Karenina, arguably the most important character to the novel, gets many of her key traits brought forth by relationship problems. Anna's search through her quest for love is purely emotional, and at the end of her character's life Anna's reason fails her. She has too much feeling and emotion, a trait shared by many of Tolstoy's characters. Her feeling from her relationship tend to overpower her thoughts and opinions, giving the novel a sense of romanticism. She becomes disgruntle. In the end, Anna can't hold her own wits. Tolstoy uses characterization to present Anna, through the relationships she has it can be understood her attitude and personal qualities. Levin, one of the main partners in a relationship with Anna, is the hero of Anna Karenina. Through Tolstoy's tone and description in the interaction between Anna and Levin it is almost gathered that Levin was created to merely point out his superiority, and his relationships with Anna does directly that. Where Anna continually m...

Word Order in English Sentences

Word Order in English Sentences Word order  refers to the conventional arrangement of words in a phrase, clause, or sentence. Compared with many other languages, word order in English is fairly rigid. In particular, the order of subject, verb, and object is relatively inflexible. Examples and Observations I cant see the point of Mozart. Of Mozart I cant see the point. The point of Mozart I cant see. See I cant of Mozart the point. Cant I of Mozart point the see . . . I cant see the point of Mozart.  (Sebastian Faulks, Engleby. Doubleday, 2007)[A] characteristic of modern English, as of other modern languages, is the use of word-order as a means of grammatical expression. If in an English sentence, such as The wolf ate the lamb, we transpose the positions of the nouns, we entirely change the meaning of the sentence; the subject and object are not denoted by any terminations to the words, as they would be in Greek or Latin or in modern German, but by their position before or after the verb.(Logan Pearsall Smith, The English Language, 1912) Basic Word Order in Modern English Assume you wanted to say that a chicken crossed the road in Modern English. And assume you are interested only in stating the factsno questions asked, no commands, and no passive. You wouldnt have much of a choice, would you? The most natural way of stating the message would be as in (18a), with the subject (in caps) preceding the verb (in boldface) which, in turn, precedes the object (in italics). For some speakers (18b) would be acceptable, too, but clearly more marked, with particular emphasis on the road. Many other speakers would prefer to express such an emphasis by saying something like Its the road that the chicken crossed, or they would use a passive The road was crossed by the chicken. Other permutations of (18a) would be entirely unacceptable, such as (18c)-(18f). (18a) THE CHICKEN crossed the road[Basic, unmarked order](18b) the road THE CHICKEN crossed[Marked order; the road is in relief](18c) THE CHICKEN the road crossed*(18d) the road crossed THE CHICKEN*[But note constructions like: Out of the cave came A TIGER.](18e) crossed the road THE CHICKEN*(18f) crossed THE CHICKEN the road* In this respect, Modern English differs markedly from the majority of the early Indo-European languages, as well as from Old English, especially the very archaic stage of Old English found in the famous epic Beowulf. In these languages, any of the six different orders in (18) would be acceptable . . ..(Hans Henrich Hock and Brian D. Joseph, Language History, Language Change, and Language Relationship: An Introduction to Historical and Comparative Linguistics. Mouton de Gruyter, 1996) Word Order in Old English, Middle English, and Modern English Certainly, word order is critical in Modern English. Recall the famous example: The dog bit the man. This utterance means something totally different from The man bit the dog. In Old English, word endings conveyed which creature is doing the biting and which is being bitten, so there was built-in flexibility for word order. Inflection telling us dog-subject bites man-object allows words to be switched around without confusion: man-object bites dog-subject. Alerted that the man is the object of the verb, we can hold him in mind as the recipient of a bite made by a subject we know will be revealed next: dog.By the time English evolved into Middle English, loss of inflection meant that nouns no longer contained much grammatical information. On its own, the word man could be a subject or an object, or even an indirect object (as in The dog fetched the man a bone). To compensate for this loss of information that inflection has provided, word order became critically important. If the man a ppears after the verb bite, we know hes not the one doing the biting: The dog bit the man. Indeed, having lost so much inflection, Modern English relies heavily on word order to convey grammatical information. And it doesnt much like having its conventional word order upset.  (Leslie Dunton-Downer, The English Is Coming!: How One Language Is Sweeping the World. Simon Schuster, 2010) Adverbials One way to find out whether a sentence part is a subject or not is to make the sentence into a  question. The subject will appear after the first verb: He told me to add one tablespoon of honey per pound of fruit.Did he tell me . . .?We spread a thin layer of fruit on each plate.Did we spread . . .? The only constituent that may occur in many different places is an adverbial. Especially one-word adverbials like not, always, and often may occur almost anywhere in the sentence. In order to see if a sentence part is an adverbial or not, see if it is possible to move it in the sentence.(Marjolijn Verspoor and Kim Sauter, English Sentence Analysis: An Introductory Course. John Benjamins, 2000) The Lighter Side of Word Order in Monty Pythons Flying Circus Burrows: Good doctor morning! Nice year for the time of day!Dr. Thripshaw: Come in.Burrows: Can I down sit?​Dr. Thripshaw: Certainly. Well, then?Burrows: Well, now, not going to bush the doctor about the beat too long. Im going to come to point the straight immediately.Dr. Thripshaw: Good, good.Burrows: My particular prob, or buglem bear, Ive had ages. For years, Ive had it for donkeys.Dr. Thripshaw: What?Burrows: Im up to here with it, Im sick to death. I cant take you any longer so Ive come to see it.Dr. Thripshaw: Ah, now this is your problem with words.​Burrows: This is my problem with words. Oh, that seems to have cleared it. Oh I come from Alabama with my banjo on my knee. Yes, that seems to be all right. Thank you very much.​Dr. Thripshaw: I see. But recently you have been having this problem with your word order.Burrows: Well, absolutely, and what makes it worse, sometimes at the end of a sentence Ill come out with the wrong fusebox.Dr. Thripshaw: Fusebox ?Burrows: And the thing about saying the wrong word is a) I dont notice it, and b) sometimes orange water given bucket of plaster. (Michael Palin and John Cleese in episode 36 of Monty Pythons Flying Circus, 1972)

France's Resistance to the Membership of Turkey in the European Union Essay

France's Resistance to the Membership of Turkey in the European Union - Essay Example Since 1963, Turkey has had the privilege of being an associate member of the European Union. (ARIKAN, H. 2006). On 14 April 1987, Turkey officially forwarded an application to accede to the European Union. The events that followed the membership bid, has become a major controversy over the last two decades. Turkey, apart from the ten founding members, was one of the first countries to become a member of the Council of Europe in the year 1949. Furthermore, Turkey was also one of the founding members of The Organization for Economic Co-operation and Development (OECD). (JOSEPH, J. S. 2006). Since 1992, Turkey has had an associate membership with the Western European Union. Moreover, Turkey also fulfills its services in the United Nations, as a member of the Western Europe branch of the Western European and Others Group (WEOG). (BELKE 2004). In 1995, a Customs Union Agreement was signed between Turkey and the European Union. At European council’s summit held on 12 December 1999, Turkey was recognized as a candidate for membership in the European Union. Despite the fact that Turkey has contributed tremendously for the welfare of European countries, ironically its accession to the European Union remains at a standstill. Furthermore, France has always resisted Turkey’s membership in the European Union. (JUNG, D. et al 2008). The motive behind the resistance is not entirely based upon religious affairs. Moreover, the resistance has not stemmed due to a single reason, it is however, a cumulative result of numerous underlying issues. This Paper includes an overview on the ongoing enlargement process of the European Union and attempts to throw light at some of the major reasons forcing France to neglect strong Europe-Turkish ties and fiercely resist Turkey’s accession to the EU. The paper also attempts to weigh Turkey’s chances of accession to the European Union. Furthermore, the paper also attempts to speculate on whether France’s resi stance is justified. Overview: The long awaited accession negotiations finally opened on 3rd October, 2005. Turkey embarked on a long difficult journey of negotiations and it might take a decade before a decision is finalized. (ARIKAN, H. 2006). The terms of accession and the future benefits that turkey could give to the European Union, if its membership is confirmed, are two issues which have created an unclear and perplexed scenario. (JUNG, D. et al 2008). In order to become a member country, Turkey has to make tremendous efforts to fulfill the Copenhagen Criteria. Firstly, Turkey has to stabilize its political conditions by creating stable institutions which would ultimately guarantee and follow a democratic system and fulfill all the norms of a full European democratic country. Secondly, Turkey must transform into an economically strong country by creating a sound functioning market economy. Moreover, the EU expects Turkey to adopt and strictly adhere to the â€Å"acquis commun autaire† i.e. a set of EU laws. Thirdly, Turkey must reform its foundation in an effort to fully adopt and implement the political, economical and monetary Laws of the European Union. (TOGAN et al 2005). Opponents of turkey consider the country to be too big and too poor to join the European Union, on the other hand, some opponents consider Turkey to religious to be allowed to become a part of the European Union. Proponents of Turkey consider such opponent claims to be nothing but dubious notions because they recognize Turkey as an economically strong nation. Furthermore, they recognize the fact that Turkey is not bounded by a single religion as the Nation has no official religion thus, the issue of religion should not be treated as a major stumbling block to Turkey’s dream of accession to the European Union. (ENGERT, S. (2010). Turkey’s accession to the EU-A long, troubled journey: Since 200 years, Turkey has been trying to

Alzheimer's disease and relationship to nutrition and hormone Essay

Alzheimer's disease and relationship to nutrition and hormone - Essay Example Alzheimer is mostly seen in individuals who are above the age of forty five and it principally develops into dementia in its latter stages. It is characterized by loss of cognitive abilities which occurs due to the loss of normal brain functions. In the latter stages of Alzheimer Disease the sufferer becomes totally disoriented and shows memory loss such that he is not able to recognize his very close family members. (Evans et al, 1989; Gao et al, 1999). The primary feature of Alzheimer Disease is the atrophy of the cortex. But in some cases it is seen that neuritic processes may accumulate, abnormalities in cerebral nucleus may occur or amyloid angiopathy may be seen. The question now stands as to why Alzheimer disease onsets in an individual. To answer this question many aspects of the disease are analyzed. Nutrition is presumed to be directly related to the onset of Alzheimer’s disease. Research done on the relation of the nutritional status of an individual has shown that Vitamin D may have a direct relation with the onset of Alzheimer. A research by Dr Grant proves that Alzheimer’s may be related to low serum levels of Vitamin D. It is said by Dr Grant that old people usually have the deficiency of Vitamin D because of which dental caries, diabetes mellitus and depression may arise in individuals. And all these diseases together are presumed to be a cause for Alzheimer Disease. Relating nutrition to Alzheimer has paved way for many researches to be done on this issue (Drug Week, 2009). Such a research was done to find the relation between folate and the risk of Alzheimer Disease. It was seen in this research that individuals who consumed folate were greatly reducing the risk of acquiring Alzheimer Disease. The incidence rate was calculated to be 45% as the individuals consuming folate were decreasing their risk of acquiring Alzheimer by 55%. The research compared the individuals who were taking folate regularly to those who were not and it was
