Wireless Network Security - Research Paper Example These days wireless networking has become an attractive trend and the professionals in all over the world are adopting wireless network security with advance trends and new features in order to protect their networks from various security threats. In other words, it can be said that these  networks  have the capability to launch interconnection among various devices. In this scenario, the main advantage that we gain from wireless networks as compared to other networks is that this technology releases us from the use of wires. In view of the fact that the communication among several nodes is established through radio waves thus there is no need of wires for establishing a network. Additionally, the wireless adapter which is located inside the machine transforms data into the radio frequency transmission and later on broadcasts it. In addition, wireless  technology is normally acknowledged as Wi-Fi technology or simply WLAN technology. In this scenario, the wireless security is t he main feature that we discuss throughout wireless networks   (Makker; Moran; Turban, Leidner and McLean). Another  advantage  of these  networks  is that users of this network are not bound to limited location despite of its usage where they have facility of signals. Hence it decreases the  expenditure required for cabling or wires that is required in wired  networks. In addition, wireless technology helps us to release from the copper wires. Here one important thing to remember is the wireless security for Wi-Fi applications.... Hence it decreases the  expenditure required for cabling or wires that is required in wired  networks. In addition, wireless technology helps us to release from the copper wires. Here one important thing to remember is the wireless security for Wi-Fi applications. In this growing era where technological aspects are growing with users of economy related needs, we have to fulfill all the essential requirements for establishing an effective wireless network. Thus, the wireless network security is a major issue that is to be considered while establishing wireless networks (Weber and Bahadur; Makker). Why wireless security is Important? †¢ It is important due to the fact it is now accessible everywhere, and hardware required for it has a low cost that will facilitate a common user to purchase it from market (Asadoorian). †¢ The aspect of Wi-Fi is used in almost every advanced application round the globe. Hence flexibility increases. We can observe that this innovative techno logy is now available easily in everything. We have example of those things that we use in our daily life like mobile phones to our daily life usage appliances (Asadoorian). †¢ Although it is a true fact that the fame of Wi-Fi technological hotspots are enhancing. In most of applications wireless security is not implemented properly (Asadoorian). †¢ As we know that Wi-Fi technology could pass through long distances thus security needs are essential for making our communication secure (Asadoorian). †¢ An important perspective of Bluetooth is that this technology is spreading and almost used in every spot round the world but this one is vulnerable to attack (Asadoorian).

Brave New World Essay Example for Free

Brave New World Essay Aldous Huxley was a writer of several novels, including the most famous Brave New World. He was born on 1894 and died on 1963. His interest includes politics, philosophy, parapsychology, psychology and mysticism. He was known to have close relationship to several people who have inclinations towards science. He has a botanical father and had worked in a chemical plant. Brave New World was written during an era where psychology and genetics play a vital role in explaining human behavior and reactions. It is then not impossible that there will come a time that humans will be experimented using psychology and genetics to be able to determine the extent of its effect. 1)Identify the characteristics (dimensions) of the narrative. A narrative is about telling stories, thus, it consist primarily of a plot structure, conflict, characters, setting, theme and point of view. The plot structure is basically the outline or the framework of the whole narrative; it includes the introduction followed by the rising action and the climax and then the falling action and finally the resolution. The conflict on the other hand is the disagreement in the narrative; usually it is where the whole plot revolves. The characters are the players or those who perform in the narrative. The setting is where the narrative takes place. The theme is the topic or the issue/s being portray or shown as the narrative progresses. The point of view is what the characters or the author seems to think from their perspective. 2)Discover an explanation for how the narrative creates meaning. The narrative creates a meaning by putting all of its dimensions together. Weaving one with another, it generates an idea that later result to a series of story which are connected with one another. 3)What is the setting? Where does the story takes place? Brave New World starts in ‘Central London Hatchery and Conditioning Centre’, there is a tour in the Hatcheries. The director is explaining to the students the process of reproduction of ‘customized’ human beings. The story takes place during A. F. otherwise known as After Ford. 4)Who are the characters? Are they human? Fleshed out? Known and unknown traits. The first character to be shown was the ‘Director’ Tomakin. He was the director of Central London Hatchery and Conditioning Centre. As the story succeeds, he was shown to be a part of a scandal involving his impregnation of Linda, a second caste or Beta and having a son with her named John, some 25 years ago. The next character was Linda Crowne, she is another Beta which depicts the typical female in the Brave New World. She is nineteen years old and is a lab worker at the Conditioning Center. She is Bernard’s love interest and she also like Bernard. Bernard is the main character in the story, he works as a psychologist in the Conditioning Centre and belongs to the Alpha class or the first class. He is the one to expose the son and wife of Director Tomakin. John or more commonly known as ‘the savage’ is the son of Linda and Tomakin. He lives in the savage Reservation along with her mother. He causes the big embarrassment for the director. He found his mother in the dying bed. He serves as the character who lives in the old world or something like that. Mustapha Mond is one of the World Controller. At the beginning of the narrative he told the students who are touring the Control Center about monogamy and the bond between mother and child, which he remarked as ‘horrifying’. Helmholtz Watson looks like Bernard’s Bestfriend and adviser. He like Bernard is not in favor of the ‘new order’ he thinks that there is something that is not right in the system. Ford is another term or shortcut for Freud which serves as the new ‘God’ as revealed in the story by Mond. Other characters are just minor characters. Among the characters, ‘the savages’ are the only one who is really humans’ or those who become humans in the natural sense. Other characters are fleshed out. Although they are till humans are homo sapiens, they are not created in the normal process. As stated above, they are somehow, customized. 5)Who is the narrator? Attitude toward story? Powers available to narrator? Characteristics? Trustworthy reliable? The narrator is actually not among the characters thus he/she have the capability to tell the readers what is actually taking place in the narrative. The narrator’s attitude is somehow against the world order but it seems that the narrator is curios of what will happen after things are going this and that way. I could not say for sure if the narrator is trustworthy and reliable since there are instances wherein he/she tries to guess part of the story. Also, since the narrator is not an actual character it is hard to tell how much is his/her if his/her interpretations are coherent. 6)What are the events? Which are important for the story’s development? Which flesh out the story? The first three chapters generally describe that ‘brave new world’. The tour in the Control Center gives us a brief overview of the workings involved in the conditioning and reconditioning of the people, from conception to old age. Then the presentation of Lenina as the typical human being during that time in contrast with Bernard who seems to deviate with what is foreseen as natural. The visit to the Savage Reservation which shows the members of the old world and how they live corresponds to the presentation of a small part or population who still live in the ‘old system’. Meeting John and Linda who turns out to be the Director’s family, John being a child conceived through normal sexual intercourse which the new society or the Fordian society believes to be obscene. The presentation of John as the son followed by the fame of Bernard that was only short-lived since John did not show up in the conference which was arranged to confirm his identity. Then it shows the Shakespearean love that John felt for Lenina while Lenina shows the love she knows, this leads him to beat her. It was then followed by Linda’s death which leads to a riot at the hospital. This leads to the arrest of Helmholtz, Bernard and John. Bernard and Helmholtz were sent to another island far from England. John on the other hand was permitted to live n England. The people in England seems to drive John crazy, thus at the end, he killed himself. 7)How are events related in time? How are they told in the story? (Flashbacks? ) What is the speed or pace of the story? The events are related as the story progresses however there are indeed some flashbacks especially the scenes with John in the savage Reservation. The speed of the story is fast paced but there are enough explanation for every scenes. 8)What are the causes and effects? Are causes human? Supernatural? Are effects caused by accidents? Forces of nature? The Causes are the humans as can be seen since it is the humans who create the ‘brave new world’. Accordingly, the world is patterned to how Freud had conceived family as a disintegration of individual. The new order also aims to promote happiness by controlling everything in the human life. The effects are not merely accidents but an understanding of a ‘utopian’ view. 9)Who is the audience? What can we tell about the audience’s knowledge, personality, and abilities, on the basis of the speaker’s attitude toward audience? The audience is basically the reader which is also the spectators who are looking forward the development and progress in the narrative. The speaker speaks of the audience as someone who wants to join or be included in the ‘utopian like’ world where everything is equal yet individuality is missing. 10)What is the theme? It may be an underlying truth or saying. How obvious and clear is the theme? â€Å"Community, Identity and Stability has been the central theme of the whole novel since it is even the motto of the ‘new order’. The theme is very obvious since it is discussed in the novel. Stability is always mentioned with its reference to control and less conflict. Science seems to be the central source of power in the ‘brave new world’, science is used to provide less conflict through conditioning and minimizing conflicts. 11)Does the narrative fulfill its creator’s purpose? I believe it has fulfilled its creator purpose of delivering a novel that shows a future society if it will be designed or patterned to a ‘communal, scientific capital system’. Everyone will be treated in the same way. People do not experience loneliness because they are conditioned to be like this and do that. People are treated as mechanisms and/or things that can be rejected if it does not suffice its purpose. People live and die with the purpose of living together harmoniously in a fake reality. 12) Does the narrative provide useful ideas for living your life? Yes, it had me thinking of my own view regarding Utopia. It also gives me an insight about the way society has effects on the individual. The way the society can shape and somehow manipulate what an individual will think and how he/she will react. Also, it shows that although science, in general and genetic engineering in particular, may be used to treat illnesses and can improve life, it might also result to artificial human beings which are created in laboratories.

American Society Portrayed in Tolkins The Player and Among the Dead :: Tolkin Player Among the Dead

A Fractured American Society Portrayed in Tolkin's The Player and Among the Dead The novels 'The Player' and 'Among the Dead' are not simply tales about any given character, as it would appear, but in fact they represent Tolkin's own personal vision of what he thinks American society is becoming. Namely, that it is a fractured society built on false values, where people have difficulty dealing with the truth of feelings or situations and where people will do anything to make money. The individual plots are realistic though, and they seem to work as both true-to-life dramas and broader social commentaries. This gritty realism becomes apparent after a brief look at the events of each novel. Part of a major Hollywood executive's job is to reject writers in the polite 'don't call us, we'll call you' fashion. But when 'The Players' Griffin Mill starts to receive death threats from an anonymous writer, he panics. In an attempt to clear his conscience of not replying, he contacts a writer at random from his old diary, who he can't even remember, and chases him down to apologise and offer him a job writing a new film. But when the writer laughs in Griffins face, Griffin goes mad with frustration and murders him. The rest of the story involves Griffin's slow breakdown involving: knowing he'll get caught; his romantic attachment with the writer's widowed girlfriend; his realisation of knowing he's getting older and a new young hot-shot producer threatening his job, and the real death-threatening writer still trying to kill him. This also acts as a broader social commentary on the way American society, particularly Hollywood, is made up of lies, false values and dishonesty to th e point of absurdity. 'Among The Dead' begins with another executive, Frank Gale, writing a letter. This letter is a carefully crafted 'forgive-me' note in which he confesses to an affair he's been having. The plan is to take his wife on holiday and give her the letter and then spend the rest of the time trying to sort out their marriage. But Frank takes too long saying goodbye to his mistress and he ends up missing the plane, which then crashes killing everybody on board, including his family. The book then follows Frank dealing with his wife and daughter's death and the way in which the Airline company find Frank's letter in the wreckage, and sell it to create a sensational news story and also in defence against a law suit from the victims of the crash's families, as blackmail against Frank.

Analyse the ways that the director builds suspense and scares the audience in the film JAWS

After the horrifying release of Steven Spielberg's classic ‘Jaws', the word has since then been associated with the monstrous killer in the ocean, the 20 foot great white, teeth covered in the flesh of an unsuspecting victim, swimming in a pool of blood. Steven Spielberg uses a variety of tricks and techniques to build suspense. Different camera angles, zooms, music and many other ways are used by Spielberg to create the tense atmosphere that is Jaws. These tricks and techniques all helped steady the bricks of Spielberg's masterpiece. Without these techniques, the impact that Jaws had imprinted upon the audience would not have been present. These tricks and techniques will be critically analysed to see how they had been used so efficiently to create an unwavering tower of suspense and drama. Jaws is set in the beautiful tranquil island of Amity. The air is calm and peaceful. Kids can be seen in the distant, splashing up and down in the deep blue ocean. You can see the tension relax as people lie in the hot summer sand, eyes drifting into their own world. Amity Island: the perfect holiday. However, the serene atmosphere is twisted apart when the ‘jaws' of a Great White appears. After the merciless deaths of four people, our protagonist, Chief Brody, must take action to stop the murderous beast from feeding once more upon the people of amity. Teamed with the marine biologist Matt Hooper and the crazed fisherman, Quint, they must set off to hunt down the Great White. Jaws is set on Independence Day, a national American holiday on the 4th of July. This was the day that the US formally adopted the Declaration of Independence from the UK. This would make the perfect scenario for Jaws. Teamed with the hot summer weather typical of July and the bustling holiday, the beach created the perfect scene for a Great White shark to attack. People would gather at the beach, the mood would be joyful. One Great White shark and the chaos that would form would be uncontrollable Music plays an important role in Jaws. Without the music, the suspense would all break down. Steven Spielberg uses music in a special way. He links a certain piece of music to the shark, which essentially becomes the sharks theme. Whenever this theme is played, the audience's first thoughts would be of the shark. The audience is in constant caution of the shark's presence, not knowing when or if it actually will attack. This not only creates suspense, but also creates the fear of knowing that the shark is most likely present. However, with this, Spielberg can also create false alarms. Due to the fact that the music is affiliated to the shark, the music can be used to create the illusion of an attack when there is nothing. This creates doubts in the audience's mind, who were sure that there would have been an attack. This also creates tension because of the fact that Spielberg can then surprise the audience with an actual shark attack. The main theme is also really simple; just two notes, forming something similar to a ‘duh dah' sound. With this simple rhythm, Spielberg can increase the speed of the two notes creating a faster sense of suspense and danger. Spielberg makes the notes fade into the scene as a ‘non-diegetic' sound. This means that the sound is present outside of the scene, only detectable by the audience and not the characters. Because it is non diegetic, only the audience will hear the theme, thus making them more nervous/tensed due to the fact that the characters remain clueless of the fate that may await them. The music starts of slow. It speeds up as the action gets more intense and it halts suddenly. The audience will have no idea what is going to happen. At this stage, Spielberg does two things. Create a false alarm, and nothing happens or he makes an attack. The audience will not know whether it will be an attack or a feint, which is why the music is so effective. What is also effective is the lack of music. Or any sounds at all. This creates a sense of emptiness. The lack of any non-diegetic sounds mixed with diegetic sounds such as the screaming of a victim creates a sense of fear. We hear it not as an audience, but from the ears of the victim, which is what scares us the most. Diegetic sounds are also used by Spielberg. Diegetic sounds are sounds outside the scene. These could include many things such as the waves crashing, the chatter of the characters or the music playing in the scene such as an instrument or radio. With this, we can feel the emotions/feelings of the character in more depth, because we are hearing what they hear, not something created outside the scene. But what may also be effective are camera techniques. These can be camera shots that are moving, still, from a certain angle or even from the perspective of someone/thing in the scene. Camera techniques are used most efficiently in an action scene, such as in the first attack with the young girl called Chrissy. This scene starts off with the camera focusing on the whole group of teenagers. We can hear the Diegetic sounds such as guitars, the waves and even the crackling of the fire. The young girl, Chrissy, and a young boy move away from the scene. The camera follows them. Soon, they arrive at the oceans end. The camera isn't clear and the scene is dark. This creates a relaxed but mysterious atmosphere. The young girl goes into the ocean as the boy is getting ready to go in. The camera then focuses on the young girl in the ocean. As we see her swimming, suddenly, a certain theme appears causing tension. This theme is the theme that symbolizes the shark. It starts off lightly, as the girl is still swimming, unwary of any dangers. Soon, the music becomes faster and louder. The camera angle then changes. It appears under the water. We see the view from the camera from under the water to above, as if it were from the perspective of something. Soon, the audience realizes that there is something in the water, which is the shark. We see from the shark's POV as it gets closer to the young girl, the tempo of the music gets louder and faster. And soon, the shark is near attacking distance of the girl. Suddenly, the camera goes above water and points at the lone girl, swimming. All non-diegetic sounds stop, as we hear only the waves and the girl. And then, all of a sudden, we see the girl pulled down. We hear just the screams, which causes a greater sense of fear. The girl struggles, only to show and flatter the strength of the shark. The girl is then pulled under the water and all of a sudden, the screams disappear. All we can hear are the waves. The camera then becomes still, pointing at the distance in the ocean. All is silent apart from the waves. All this is to emphasize what had just happened, as all we can think about is the scene that had just occurred, as the camera movement is still, pointing to ‘nothingness'; just the plain ocean. The sun then rises, symbolizing the time passing. What we need to realize is not once was the attacker, the shark, shown in clear view. All we saw was the view from the eyes of the shark, and the view of the young girl being attacked from something cloaked by the ocean. This is to create more fear in the shark and create more tension. The second attack is against a young child called Alex. In this scene, we are at a lively beach. There is a happy atmosphere. We can hear children playing, water splashing, waves crashing. It's a fast pace. However, we know something is going to go wrong. We see chief Brody on the beach. His worried face and constant suspicions create fear and tension in our minds, thinking about the shark. Chief Brody's fear deeply contrasts with the whole beach's excitement, creating unwariness in the scene, due to the main focus being on Brody and the outside focus being on the beach. Brody, being on the constant lookout, is being cautious of every single detail, causing great exaggeration in small details. This creates suspense, as we don't know what will happen due to all the false alarms that go on in this scene. We see a wide shot on all of the people in the ocean. Chief Brody is paranoid, causing the smallest things to seem as if they have a large effect. The first example of this is the girl screaming. This scream causes the audience to become paranoid due to the contrast in Brody and the atmosphere. Brody is distracted, causing him to become more anxious to see what was going on. However, the scream was meaningless, which was the first false alarm. The second false alarm was the old man and woman. The old man swam underneath the water and slowly rose, causing Chief Brody to think it was a shark, only to be relieved and slightly frustrated at the fact that it was just a person. This all creates a sense of unpreparedness to the actual attack due to the false alarms. The false alarms create a feeling of reassurance. Chief Brody's wife starts to relax him, allowing him to ease his paranoia of the shark. Then suddenly, the atmosphere changes. The familiar music plays. The disappearance of a dog into the water highly implies that something is there. The audience is now aware of something being there, however, Brody is unfocused and the whole beach has now idea what was going to happen. And all of a sudden, as the theme gradually becomes louder and faster, the camera shot goes underneath. The POV is now from the sharks. We see several vulnerable children from under the ocean, their legs sticking out. However, the shark goes closer and closer to a single person. As the shark goes closer, the music speeds up and tension rises. And soon, the shark attacks. The people on the beach have no idea what's going on, and the sudden atmosphere change causes a chaos. Brody notices too late. Soon, everyone evacuates, however, one person is still searching desperately for someone. As the scene ends, a young boy's life jacket appears on the shore and the camera focuses on it completely, torn and slightly covered in red. The audience realizes that whoever owned that jacket was the victim. The shark is the main object of fear in Jaws. It appears out of nowhere, shocking the audience. The fact that it doesn't show the shark directly creates uneasiness and a feeling of defencelessness. It makes it seem menacing that it attacks, creeping through where no one can see it. The unusual size and the intimidating pictures that are shown to study the shark creates a scary image, due to the fact that the actual shark itself isn't shown until later. And the music, it creates a sort of stealth for the shark. If the music is on, the shark is assumed to be there. If the music is not on, the shark is not assumed to be there. The false alarms were all created for one purpose, the real attack. The false alarms led to the audience easing up, but then to be surprised by the actual attack. Near the end of the film, the jetty used to capture the shark is small and unstable. Compared to the shark, it is miniscule. The phrase ‘we're going to need a bigger boat' said by Brody shows that it's in vulnerable to the shark's giant size. It isn't sufficient enough. The feeling of breaking down and falling into the ocean, where you are practically food for the shark creates suspense. It could break down any time. Overall, Jaws was an excellent film and the techniques by Steven Spielberg completed it. The scariest parts were no doubt, the unpredictable shock. They came out of nowhere and broke apart the suspense with no warning. The film was a big success and appealed to me greatly.
