Frankenstein 72 Essays - Frankenstein, English-language Films Frankenstein 72 In agreement that Mary Shelly's novel, Frankenstein takes its meaning from tensions surrounding the cultural concerns of human nature, its potentials and limits and forces that go into the making. The following will support this statement and tie traits from the book to today's society. Many lessons are embedded into Mary Shelleys Frankenstein, including how society acts towards the different. The monster fell victim to the judging of a a person by only his or her outer appearance. Whether people like it or not, society summarizes a person's characteristics by his or her physical appearance. Society has set an unbreakable code individuals must follow to be accepted. Those who don't follow the standard are hated by the crowd and banned for the reason of being different. When the monster ventured into a town he had hardly placed [his] foot within the door before the children shrieked, and one of the women fainted . From that moment on he realized that people did not like his appearance and hated him because of it. If villagers didn't run away at the sight of him, then they might have even enjoyed his personality. The monster tried to accomplish this when he encountered the De Lacey family. The monster hoped to gain friendship from the old man and eventually his children. He knew that it could have been possible because the old man was blind, he could not see the monster's repulsive characteristics. But fate was against him and the wretched had barely conversed with the old man before his children returned from their journey and saw a monstrous creature at the feet of their father attempting to do harm to the helpless elder. Felix darted forward, and with supernatural force tore [the creature] from his father, to whose knees [he] clung... Felix's action caused great pain to the monster. He knew that his dream of living with them happily ever after would not happen and with the encounter still fresh in his mind along with his first encounter of humans, he declared everlasting war against the spe cies, and more than all, him who had formed the creature and sent him forth to this misery. The monsters source of hatred toward humans originates from his first experiences with humans. In a way the monster started out with a childlike innocence that was eventually shattered by being constantly rejected by society time after time. His first encounter with humans was when he opened his yellow eyes for the first time and witnessed Victor Frankenstein, his creator, rush out of the laboratory. Would this have happened if society did not consider physical appearance to be important? No. If physical appearance were not important then the creature would have had a chance of being accepted into the community with love and care. But society does believe that physical appearance is important and it does influence the way people act towards each other. Frankenstein should have made him less offending if even he, the creator, could not stand his disgusting appearance. There was a moment however when Frankenstein was moved by the creature. He felt what the duties of a creator towards h is creature were and decided that he had to make another creature, a companion for the original. But haunting images of his creation (from the monster's first moment of life) gave him an instinctive feeling that the monster would do menacing acts with his companion, wreaking twice the havoc! Reoccurring images of painful events originating from a first encounter could fill a person with hate and destruction. We as a society are the ones responsible for the transformation of the once childlike creature into the monster we all know. The public doesnt realize that our society has flaws, and that they must be removed before our primal instincts continue to isolate and hurt the people who are different. With such a large amount of technology among us, some people may wonder why such an advanced civilization still clings on to such primitive ways of categorizing people. Victor Frankenstein, as he huddled in the corner of his room, with only bed sheets to offer a hint of security, plagued himself with questions as to how he could create

CANGO THIRD ANALYSIS REPORT - Essay Example It can be especially difficult to provide direct feedback to an under-performing subordinate in a face-to-face meeting. Managers are well aware that reactions to negative feedback are hard to predict. Some employees may realize the need for improvement while others may get very upset when they hear that their job performance is considered to be unsatisfactory. Imagine you are a manager and you are faced with the prospect of telling a poorly performing subordinate that he or she must improve. How would you go about doing this? What if your subordinate reacts badly and blames you for his or her poor performance? What if he or she refuses to sign the performance appraisal form leading to a review from the director of human resources management department? You could give this person a good rating, but then what would the rest of your subordinates think of your abilities as a manager? Heres another possibility: suppose you are a manager and you have developed a friendly relationship with your employees. How easy do you suppose it would be to sit down with one of these employees and tell them that they are performing poorly? Warren is faced with this very problem in the Introductory Video. He must appraise the performance of a poorly performing subordinate, a task with which he is clearly uncomfortable. Watch the video now and consider what you would do in this situation.

Dells Competitive Strategies And Supply Chain Dissertation

Dells Competitive Strategies And Supply Chain - Dissertation Example Founded by Michael Dell in the mid-1980s, Dell computers is one of the leading computer technology corporations in the world. At the height of the technology boom of the early 1990s, Dell reached a level where it had grown too large too fast to a point that it had to make radical internal changes to stay profitable. The company’s rock bottom was in 1993 when it lost a considerable portion of its market share, saw its cash flow and net income drop to $20 million and negative $ 40 million respectively. This called for rapid strategic changes to keep the organization afloat.  The company created a lasting profitability strategy through three major elements of; virtual integration, true value customer service features and having tailor-made manufacturing to meet specific customer needs. When Dell initiated computer sales through its website in 1996, it was an industry first, and when it expanded its line of products to include televisions, printer and audio players in 2002, the company had, in essence, the path of diversification aimed at sustaining profitability.   These events coupled with the organization’s three pillars of sustainable profitability saw it hold the spot of the largest seller of PCs worldwide in 2004 at 17.9% in 2004 up from the previous year’s 16.7%, followed closely by HP at 15.8%.

This called for rapid strategic changes to keep the organization afloat and that is exactly what Dell did. The company created a lasting profitability strategy through three major elements of; virtual integration, true value customer service features and having tailor made manufacturing to meet specific customer needs. When Dell initiated computer sales through its website in 1996, it was an industry first, and when it expanded its line of products to include televisions, printer and audio players in 2002, the company had in essence the path of diversification aimed at sustaining profitability. These events coupled with the organization’s three pillars of sustainable profitability saw it hold the spot of the largest seller of PCs worldwide in 2004 at 17.9% in 2004 up from the previous year’s 16.7 %, followed closely by HP at 15.8%. For a company that saw negative net income 10 years ago, this market share was quite impressive. Chapter 2: Theory of business and competitive strategy A macro-environment is the total sum of external factors that have influence on a business. These factors are usually beyond the control of an organization’s management and range from demographic, political, and technological to economic forces. Economic forces in this environment include demand and supply, the amount of competition in a market segment, economic resources available and the efficiency of production methods adopted by an organization (Hatten, 2012: P91). Each of the mentioned economic forces have an impact on both an organization’s production output and possible profit margin from the goods

The Canterbury Tales Essay Example for Free

The Canterbury Tales Essay What do we learn about religion from studying the general prologue of The Canterbury Tales, With reference to two of the characters, the prioress and the Monk? Geoffrey Chaucer was born in 1340, his family were from London. Chaucer became a page in royal court and was educated with highly experience of people around him from the very rich to the ordinary working man helped him to write the Canterbury Tales. The Canterbury Tales is a framework story. It is about a group of pilgrims who go on a pilgrimage to Canterbury. While at the Tabard Inn, on the night before the journey, Chaucer describes them, The Monk and the Prioress are two of the pilgrims travelling with Chaucer. Using irony, Chaser seems at first to be compliment them. This is when his character he realises he is pointing out their fault and the criticising the church. The prioress was a Nun who travelled with Chaucer to Canterbury. While in the Inn Chaucer describes her, saying, That of hie smylyng was ful simple and coy. Chaucer also writes, hir gretteste ooth was by saint Loy. Nuns are meant to be holy, they have committed there lives to God, they are meant to follow the commandments given to Moses, not even to swear a little bit is acceptable let alone to swear at all. Chaucer also writes, Ful;wel she song the survace divine, She was singing not to please God but to catch the eye of the other people in the church. Chaucer says that the prioress ate her meal with elegance, he said she had beautiful manners and that she was entertaining to watch, Mate wel y taught was she with alla, Amyable of port. Later on in the text Chaucer comments about her beauty on a number of occasions. Nuns have to take a vow of poverty and should not have any possessions. Clearly she possesses make-up and fine clothes. God should be the Centre of her life and she should only be doing things he wants her to do. Chaucer thinks that the prioress isnt acting and behaving as she should and that she should forget about the pilgrimage to Canterbury and start to learn once again about being a nun. The Monk was according to Chaucer a fine looking man, Fair for the mainstrve, This man was not just a monk but an outryere. In those days lots of irony was used and an outrider was a person who could go out of his monasteries to do work for the church. Chaucer also sats that this monk, lovede Venerye and Ful many a deyntee hors haddle he in stable. The monk had taken a vow of poverty just like the prioress, so this monk shouldent have any possessions. Chaucer also writes about his brydel which was Gynglen in a whistynge waynge wynd. This monk was also drawing attention to himself while he was meant to be out doing the work of the church; he was treating this work like a holiday. This monk was fashionable and enjoyed best quality food. A fat swan love he best of any roast. Swans were very expensive, so he must have eaten this while he was out doing the work of the church. He was caring for his freedom, not commitment while he should have been caring for the poor not indulging himself. Although Chaucer wrote the Canterbury Tales about 600 years ago, it is still valid today. The nun and the Monk speak for themselves, they say that human nature doesnt change and that some people will always be greedy and selficha dns some people will be nice and kind, this was Chaucers job, to show them up in his writings.

The Godmother of All the Pretty Horses Essay -- Essays Papers

The Godmother of All the Pretty Horses In analysis of the character, Duena Alfonsa, in the novel All the Pretty Horses by Cormac McCarthy, facets of her character are clearly revealed. From her physical deformity to her feelings of her father keeping her exiled in her own country, seventy-two year old Alfonsa is filled with a lifetime of complex situations. Her character was consistent and motivational in wisdom and provided greatness in her role in the novel. She is a grandaunt and godmother of Alejandra, a young teenager still in school. The Duena, one could say, is the "Godfather" of the novel. She literally "goes to the mattresses" in protecting her grandniece from a man. After seventy-two years of life, Alfonsa speaks of her life's experiences at an elevated level of knowledge. She is formal, polite, and full of assuredness. McCarthy describes Alfonsa's appearance as an "elegance chilling" (McCarthy 227). Her knowledge came from reading books. McCarthy writes of Alfonsa, "By the time I was sixteen I had read many books and I had become a freethinker" (McCarthy 232). Alfonsa's complexity included her physical deformity. She describes the loss of her last two fingers of her left hand in a shooting accident when she was seventeen years old where the barrel of the gun exploded while she was shooting for live pigeons. This placed her with several perspectives. Two of her perspectives in becoming deformed were, first, it lead her to the feelings...

The structure of the play Blood Brothers

At the start of the play , w see the end of the play , a flash back, although at this point we do not know its the end , all we see is 2 men dead on the floor and a very mysterious and creepy music can be heard , leaving the audience wondering what is going on. Then we learn of what is going on as the narrator recites a passage that we here a few times in the play â€Å"As like each other as two new pins, of one womb born on the self same day, how one was kept and one given away? An did you never hear how the Johnston's died, never knowing that they shared one name till the day they died, when a mother cried, my own dear sons lie slain† this passage tells the audience what's happening and gives away the plot, but it doesn't ruin it for the audience as there is still information they do not know for example, how did they die? Why did they not know they were brothers? And lots more questions, causing them to be more indulged in the play. Complication The complication in the play is when Mrs. Johnstone is forced to give up one of her sons to Mrs. Lyons to avoid losing them both to social services or going into so much debt that she just couldn't look after them. If this part of the play didn't happen, there really would be no play as it would mean Eddie and Mickey wouldn't have to meet and they would never become blood brothers, Eddie wouldn't go to university because he wouldn't of been able to afford it and Eddie wouldn't of had the good job and been able to give Linda money later on in the play and give Mickey a job. Rising action Other small complications in the play that are added in to make it more interesting and add more action are important to the play also. The love triangle between Mickey, Eddie and Linda, without this part of the play Linda wouldn't have cheated on Mickey causing Mickey to get jealous and seek out Eddie to kill him at the end of the play. But another complication which was vital and the reason that Linda cheated was Sammie shooting the man and Mickey going to prison for it , if this didn't happen Mickey wouldn't of got depressed had to take his Tablets , he wouldn't of slowly pushed Linda away, and as I said , Linda wouldn't have cheated. Climax The climax of the play is obviously the end sequence which starts with Mrs Lyons who at this point in the play has become a paranoid wreck showing/telling Mickey that Edward and Linda are together, This is a catalyst for the ending everything in the play after this point speeds up (the music, the speech the movement) Mickey is outraged by what he now knows about his wife and Ex best friend so he runs home finds the gun that Sammie used to shoot the man earlier in the play and goes in search of Eddie , during this he the female characters realise what's about to happen and emotions hit there peaks â€Å"he's †¦. Mickey†¦. Mickey's got a gun† (Mrs. J) (p97) the tension and speed increases more and more as we get closer to the end. Shouting and screaming increases the tension, Mickey reminds the audience of what has happened throughout the play â€Å"FREINDS! I could kill you. We were Friends weren't we? Blood brothers, wasn't it? Remember?† then it finally hits the peak when Mrs Johnstone tells them there brothers and they both are shot, Mickey by the police officer then Edward by Mickey. Solution The solution, although sad is the two twins dying, if it wasn't for them not knowing they were twins the play would never have been, but nothing could be peaceful and right until the problem made at the start which was them, was taken away. The secrets and lies had to come clean for the play to be ended and that meant Mrs Johnstone had to learn from her mistakes, she had to be punished for her mistakes and the superstition which pays such a key part in this play had to come true. Finally we end the Play how it started with the mysterious Narrator repeating the passage said at the start â€Å"Did you ever here the story of the johnstone twins , As like each other as two new pins, of one womb born on the self same day, how one was kept and one given away? An did you never hear how the Johnston's died, never knowing that they shared one name till the day they died, when a mother cried, my own dear sons lie slain†. The narrator The narrator in the play plays a very important character in the play, like most narrators he tell the story, but this narrator is slightly more mysterious and complicated than most. He is a ghost like figure; He seems to always be there, but is never seen by the characters, he is truly like a ghost , in some parts of the play he touches the characters they turn round to see who it was but they seem to see nothing although the audience see him there. I have said that the narrator plays a ghost like figure other interpretations of him would be an evil spirit or the devil, I wouldn't Say he was ever like a guardian angel though because all his references are to bad things in the play, he is never really around when happy and comical parts of the play E.G when there children are playing guns but is ever present when tension and anger is involved in the scene , also his song â€Å"The devils got your number† suggests he may be the devil or an evil spirit in connection with the devil. The narrator also continuously refers back to superstition reminding the audience of a very key factor in the play. His lines are never blunt and straight to the point either, they usually are in riddles to make the audience think. Themes The themes in Blood brothers are constantly referred to and gone back to throughout the play, usually reminded to the audience by the narrator but also quite obvious in the play. The first is fate this is mainly shown through the flash back, we see what the ending is like and we are also told by the narrator so throughout the play we know its going to end up like the start. The second and proberly most important theme is superstition â€Å"new shoes on the table, take them off† this theme is a main factor of fear in the play , Mrs johnstone is forever scared to let Mickey and Eddie play and be friends as she is scared if they find out they are brothers they will both die , like Mrs. Lyons said. The final theme is love, love pays a key part and links with superstition Mrs Johnstone loves both her sons and doesn't want them to die , But due to the love triangle between Linda , Eddie and Mickey she has to tell them showing how destructive love really is. The love of different class's is also shown in the play, we see Mrs Lyons and upper class citizen being very over protective of Eddie because she loves him so much she doesn't want him getting hurt in comparison to Mrs johnstone who would rather show her love by letting Mickey enjoy himself and have fun. Dancing Dancing is referred to a lot in the play especially in a lot of the songs, were Mrs. Johnstone refers to a lover taking her dancing or not taking her dancing. Again dancing is compared in the two social classes in the play Mrs Lyons teaches Edward to dance in a very traditional way E.g. a Waltz, were as Mickey Dances to a disco music and Rocky music reflecting on the character as Edward dances a more mature and educated dance and Mickey dances a more playful Un educated dance which doesn't have much structure. Dreams and ambitions Every Character in the play has there own dreams and ambitions again these are Very different over the two social classes. To start though Mrs Lyons has the dream of having a child, so when Mrs. Johnstone comes to her with twins that she doesn't think she can look after Mrs Lyons jumps at the opportunity. In Mrs. Johnstone case she dreams of getting a new husband, moving house, Getting money, she also gets all the things she wants†¦ but these things seem to all cause problems later on in the play , for example Mrs Lyons gets her Child but ends turning into a paranoid wreck because she feels the burden of the secret of adopting Mrs J's baby illegally is always upon her. In Mrs Johnston's case moving house and getting a new man is really ruined as they move to were The Lyons family have escaped to and Mickey and Eddie grow up together, if this wouldn't of happened they proberly would of forgotten each other preventing both there deaths. Both Mickey and Eddies dreams and ambitions also cause destruction there dreams to be like the other seems to cause jealousy which eventually causes Mickey to shoot Eddie, Eddie's dreams of university separates the 3 friends leaving Mickey to fend for himself and make the wrong choices. So to sum up every ones dreams and ambitions seem to come true in the play but they all seem to backfire on the characters. Toy guns Toy guns is an issue covered in the play which causes many problems, when the characters are kids they play with toy guns as said in the song they can get up after a count to ten , they cant die when they play with toy guns they don't understand the dangers of guns , this lack of understanding is carried out into there adulthood and it results in Mickey being put in prison when Sammie pulls the trigger and shoots someone , but still Mickey does not learn his lesson, in the final scene when Mickey holds the gun to Eddie I don't think he means to shoot him , I think he is using it to scare Edward and due to his naivety when he shoots Eddie he kills him , he kills his own brother and best friend. He has never grown up, he is still a kid inside, but the weapon he holds has.

The Great Permian-Triassic Extinction

The Great Permian-Triassic Extinction The greatest mass extinction of the last 500 million years or Phanerozoic Eon happened 250 million years ago, ending the Permian Period and beginning the Triassic Period. More than nine-tenths of all species disappeared, far exceeding the toll of the later, more familiar Cretaceous-Tertiary extinction. For many years not much was known about the Permian-Triassic (or P-Tr) extinction. But starting in the 1990s, modern studies have stirred the pot, and now the P-Tr is a field of ferment and controversy. Fossil Evidence of the Permian-Triassic Extinction The fossil record shows that many lines of life went extinct both before and at the P-Tr boundary, especially in the sea. Most notable were the trilobites, the graptolites, and the tabulate and rugose corals. Almost completely exterminated were the radiolarians, brachiopods, ammonoids, crinoids, ostracodes and conodonts. Floating species (plankton) and swimming species (nekton) suffered more extinctions than bottom-dwelling species (benthos). Species that had calcified shells (of calcium carbonate) were penalized; creatures with chitin shells or no shells did better. Among the calcified species, those with thinner shells and those with more ability to control their calcification tended to survive. On land, the insects had severe losses. A great peak in the abundance of fungus spores marks the P-Tr boundary, a sign of massive plant and animal death. Higher animals and land plants underwent significant extinctions, though not as devastating as in the marine setting. Among the four-legged animals (tetrapods), the ancestors of the dinosaurs came through the best. The Triassic Aftermath The world recovered very slowly after the extinction. A small number of species had large populations, rather like the handful of weed species that fill an empty lot. Fungus spores continued to be abundant. For millions of years, there were no reefs and no coal beds. Early Triassic rocks show completely undisturbed marine sediments- nothing was burrowing in the mud. Many marine species, including the dasyclad algae and calcareous sponges, disappeared from the record for millions of years, then reappeared looking just the same. Paleontologists call these Lazarus species (after the man Jesus revived from death). Presumably they lived on in sheltered places from which no rocks have been found. Among the shelly benthic species, the bivalves and gastropods became dominant, as they are today. But for 10 million years they were very small. The brachiopods, which had completely dominated the Permian seas, nearly vanished. On land the Triassic tetrapods were dominated by the mammal-like Lystrosaurus, which had been obscure during the Permian. Eventually the first dinosaurs arose, and the mammals and amphibians became small creatures. Lazarus species on land included the conifers and ginkgos. Geologic Evidence of the Permian-Triassic Extinction Many different geologic aspects of the extinction period have been documented recently: Salinity in the sea fell sharply during the Permian for the first time, changing oceanic physics to make deep water circulation more difficult.The atmosphere went from very high oxygen content (30%) to very low (15%) during the Permian.The evidence shows global warming AND glaciations near the P-Tr.Extreme erosion of the land suggests that ground cover disappeared.Dead organic matter from the land flooded the seas, pulling dissolved oxygen from the water and leaving it anoxic at all levels.A geomagnetic reversal occurred near the P-Tr.A series of great volcanic eruptions was building up a gigantic body of basalt called the Siberian Traps. Some researchers argue for a cosmic impact at P-Tr time, but the standard evidence of impacts is missing or disputed. The geologic evidence fits an impact explanation, but it does not demand one. Instead the blame seems to fall on volcanism, as it does for other mass extinctions. The Volcanic Scenario Consider the stressed biosphere late in the Permian: low oxygen levels restricted land life to low elevations. Ocean circulation was sluggish, raising the risk of anoxia. And the continents sat in a single mass (Pangea) with a reduced diversity of habitats. Then great eruptions begin in what is Siberia today, starting the largest of Earths large igneous provinces (LIPs). These eruptions release huge amounts of carbon dioxide (CO2) and sulfur gases (SOx). In the short term the SOx cools the Earth while in the longer term the CO2 warms it. The SOx also creates acid rain while CO2 entering the seawater makes it harder for calcified species to build shells. Other volcanic gases destroy the ozone layer. And finally, magma rising through coal beds releases methane, another greenhouse gas. (A novel hypothesis argues that the methane was instead produced by microbes that acquired a gene enabling them to eat organic matter in the seafloor.) With all of this happening to a vulnerable world, most life on Earth could not survive. Luckily it has never been quite this bad since then. But global warming poses some of the same threats today.

Business Algebra Discussion. Business Algebra DiscussionIn order to have a good understanding of the forthcoming topic on Business Algebra, it is imperative to have a good grasp and understanding of previous topics before. The most significant is the graphical representation and interpretation of a given set of data. This is because graphical interpretation of data is widely common in business algebra and it cannot be avoided. Hence, if there are and difficulties in the plotting of a data set, and in its interpretation, then the understanding and utilization of the product output would be futile. It is therefore important to have a good knowledge of this area. Linear equations provide information on how quickly data is rising or falling, and this is known as the slope or gradient of the equation. The gradient is usually a quotient of the values on the x-axis and the y-axis, with the x-axis values as the numerators. The slope of the graph is a representation of the change in values of the given data set. Linear equations are usually in the form of y= mx+ c, where y represents values on the vertical axis of a graph and x the values on the horizontal axis, m is the gradient or slope of the graph and it can be positive or negative whereas c represents the point where the lie graph intersects the y-axis. A real life application of the linear equation would be in the population demographics of a country in population census analysis. The population of a country may be analyzed for the many times that a census has been carried out. In this case, the population, say in millions of people, would lie on the y-axis while the years would be on the x-axis. By plotting the population value of a given census interval for the number of census done, a linear graph would be obtained. This would not pass through the origin and a linear equation in the form of y= mx+ c would be obtained. In this equation, the y-value would represent the population number at a given time (year) represented by x-value. Therefore, the population of a country at any given year can be predicted. The slope of the graph, m, would in this case give the rate at which the population is increasing with time, and it can be used to project the expected population of a country in the future, assuming that all other constants are maintained. This may then help the government for example on budgetary allocations. A positive slope would represent an increase while a negative slope shows that there is a decrease in the population.

The Athlete's Shack Wireless Upgrade Term Paper

The Athlete's Shack Wireless Upgrade - Term Paper Example 2 Assessment For catering the needs of the business for TAS, there is a requirement of secure and effective wireless network connectivity for all the 10 stores within the same area. There are no requirements for establishing connectivity on long distant stores. However, security is a primary concern, as data channels will be established in the environment. For addressing the security issue, Cisco provides rich features and adds an extra layer of security on the wireless networks. The embedded security technologies on a wireless architecture are now standardized, as they are available by default in all vendor manufactured wireless devices. Some of these technologies are WEP, WPA etc. Moreover, after securing the data in transit by encryption, we have also proposed a wireless intrusion prevention system that will continuously monitor and prevent the network from cyber threats. However, there is no guarantee of the network security, if the iPads are misused and stolen or snatched from o ne of the employees of TAS. For addressing human threats, acceptable use policy and password policies will be implemented. 3 Solution As the TAS environment requires wireless connectivity, ‘access points’ are required. ‘Access points’ are the device which is used to connect devices equipped with wireless technology. ‘Access points’ transmits and receive radio signals adjacent to a network hub over a limited distance. However, distant varies from different model types and wireless technology adopted. The TAS requirement is to provide access of network resources to the staff for connecting the iPads. Cisco delivers a borderless mobility experience which gives users access to the information and resources with the quality and performance. 3.1 Wireless connectivity of TAS sites TAS haw 10 stores within the same area, and there is no information regarding the distance of each of these sites with each other. When designing a wireless point to point c onnectivity, the distance is always considered due to limitation of wireless technology. Cost is also a major factor when implementing and designing a wireless network. There are two methodologies which can be adopted for connecting all 10 sites to provide Internet connectivity. 3.1.1 Wi-Fi 802.11/y It is a relatively new wireless standard defined by IEEE 802.11 standards with more enhanced capabilities as compared to 802.11n. It operates on 3.6 to 3.7 GHz on 54 Mbps with the distance of 3 miles (Parsons & Oja, 2009). The distance which is required to connect all of these 10 sites can be achieved by connecting via 802.11y Wi-Fi technology. However this technology is currently available only in United States of America. The hardware which is required to connect all these 10 sites is relatively of low cost. This is a low cost solution but it has certain limitations as it is available only in the United States. There are very few IEEE 802.11y complaint devices available. The router can be installed at any one end of either side to broadcast the signals

Wireless Security - Research Paper Example On the other hand, there are countless security and privacy issues also emerging in wireless networking environments. Though, the new technologies require more and more high level application of wireless communication networks, but such implementations are being established without giving significant concentration to privacy and security related issues. Consequently, the majority of wireless networks around the world are in danger regarding security and safety. Thus, there are a lot of chances that someone with appropriate equipment could be able to spy network traffic. In this scenario, they can get access to users’ passwords and other data (Gerkis, 2006; The State University of New Jersey, 2006). In addition, these security issues and attacks are not immediately theoretical. Additionally, techniques and tools to tap near wireless networks are extensively accessible, even for palmtop devices (Gerkis, 2006; The State University of New Jersey, 2006). In this situation there is vital need for implementing wireless security. Wireless security management has turned out to be a hot issue in literature. This paper presents a detailed analysis of wireless security related issues and their management. This research will analyze some of the important aspects of wireless security, main challenges and possible mitigation techniques. TECHNOLOGY INVOLVED IN WIRELESS NETWORKS Consider the fact that users of WLAN (wireless local area network) are able to travel along with their laptop computers and other devices from one location to another inside their offices or houses without breaking the link with the network. Thus, many corporations and general public at the present think that wireless communication based devices are very useful, efficient, and easy to operate. On the other hand, personal networks based on wireless technology help users receive and distribute data, as well as software applications, by making use of network systems and other users of the network with well-matched devices, without establishing a connection to printer cables and other secondary device links. In fact, with wireless networking users of small PDA, hand-held devices and cell phones can effectively coordinate data and information among PDAs and personal computers, as well as are able to effectively make use of internet based services l ike that web browsing, email and internet access. In addition, wireless communications can help individuals and business firms reduce their networking or wiring costs (Radack, 2011; Gerkis, 2006; css-security, 2010). In this scenario, Information Technology Laboratory established by NIST (National Institute of Standards and Technology), presents various standards and measures which can be adopted to enhance safety and security of wireless communication networks. Additionally, National Institute of Standards and Technology Special Publication (SP) 800-48,  Wireless Network Security, 802.11, Bluetooth, and Hand-held Devices, whose authors were Les Owens and Tom Karygiannis, outlines 3 main and fundamental aspects of wireless security: (Radack, 2011; Ge
