Wi-fi Wireless Technology

Wi-fi Wireless Technology Business data network and telecommunications Wi-fi has entered in to our lives some years now. It solves some problems that wire networks have but generate new. At the moment there are few advantages and a lot of disadvantages. Wi-fi can be very useful in many cases and I think it deserves a deep look in to it. Also wi-fi has many prospects for further development. Wi-fi needs specified devices in order to work properly. History The term wi-fi (wireless fidelity) is used in order to determine the appliances that are based on specification IEEE 802.11 and faction of ISM band, that is frequencies 2.4Ghz for Europe .Wi-Fi uses single carrier DSSS (direct sequence spread spectrum) radio technology but also multi-carrier OFDM (Orthogonal Frequency Division Multiplexing) radio technology. These regulations that enabled the development of Wi-Fi, are HomeRF, and Bluetooth. Unlicensed spread spectrum was available for first time by the Federal Communications Commission in 1985 and the FCC regulations were copied later with some changes in other countries and made the use of this technology enable in all major countries. Michael Marcus of the FCC staff proposed the FCC action in 1980 and the subsequent regulatory action in 5 more years. It was part of a proposal to allow civil use of spread spectrum technology and was opposed by the mainstream equipment manufacturers and many radio system operators. (Federal Communications Commission. 1985). The Wi-Fi was invented in 1991 by NCR Corporation/ATT. Initially the use was for cashier systems. The first wireless products that were brought on the market was under the name â€Å"WaveLAN† with speeds of 1 Mbit/s up to 2 Mbit/s. Vic Hayes, was involved in designing standards such as IEEE 802.11b, and 802.11a. He has been named as â€Å"the father of Wi-fi†. (Vic Hayes at 1st Home Networking Conference, 2007). Uses A device with Wi-Fi enabled, such as a PC, PDA, cell phone, game console, or MP3 player can connect to the Internet within the range of a wireless network connected to the Internet (Access point). The interconnection between one or more access points in a certain area is called a hotspot. Hotspots can cover a single room up to many squares covered by overlapping access points. The devices can network each other and connect to the Internet, share files and digital cameras can transfer video wirelessly. Wi-Fi also allows devices to connect directly with each other (peer-to-peer mode). This connectivity mode is useful most in gaming applications. When the technology released in the market there were many problems because consumers were not sure if the products from companies would work together. The Wi-Fi Alliance began as a community to solve this and to address the needs of the end user and allow the technology to mature. The Alliance created the branding Wi-Fi CERTIFIED to show to the consumers that products are interoperable with other products displaying the same branding. (Wi-fi alliance, 2000). Routers and Wi-Fi access points are used most in homes to provide Internet access and networking to all devices that are connected wirelessly or by cables into them. Devices can also be connected in ad-hoc mode for client-to-client connections without using a router. In Business and industrial environments, as increasing the number of Wi-Fi access points we get faster roaming and increased network capacity by creating smaller cells or by using more channels. Wi-Fi can enable wireless voice applications such as WVOIP. Wi-Fi installations can provide a secure computer network, firewall, DHCP server and other functions. In addition to home and office use, Wi-Fi is publicly available also at Wi-Fi hotspots provided either free of charge or under a certain price. Sometimes free Wi-Fi is provided by organizations or authorities who wish to promote business in their area. Metropolitan-wide WiFi (Mu-Fi) already has more than 300 projects in process. (Muniwireless, 2007). Standard devices Wireless access points can connect wireless devices to a wired LAN. An access point is something like an Ethernet hub, relaying data between the connected devices. Wireless adapters are connecting in the devices, externally or internally such as usb, pci and allow devices to connect to the wireless network. Wireless routers integrate a firmware application that provides IP Routing, NAT, and DNS forwarding through an interface. Wireless range extenders (repeaters) can extend the range of the wireless network. Ig the repeaters are placed in the area smart then the signal can be excellent. The devices that are connected through repeaters may have an increased latency for each hop. Each device will get signal from the device that gives better signal. With wireless bridges we can connect two or more networks between them. This is different from an access point because an access point works at the data-link layer. We can use two wireless bridges when a wired connection may be unavailable, such as a connection between two separate buildings. Most devices (routers, access points, bridges, repeaters) are designed for home or business environments. Pci cards use antenna connectors and usb only have internal antennas while some have external connections in addition to an internal antenna. In laptops it is commonly used mini pci cards. In a network between two buildings that the distance is a matter it is usually used big antennas in the roof of the buildings, so the signal can be remain strong enough. Advantages of Wi-Fi Wi-Fi allows LANs to be deployed while it reduces the cost of the network deployment. WLANS can be hosted in areas that cannot be run by cables, such as outdoor areas or even historical buildings. The prices for wireless products continue to drop, making it a fair networking option. Wi-Fi has become widespread and more and more devices obtain wi-fi technology. Wi-Fi is a global set of standards. Products designated as Wi-Fi Certified by the Wi-Fi Alliance are backwards inter-operable. Except mobile phones, any device with wi-fi standard will work anywhere in the world. Wi-Fi use WPA encryption and it is not easily cracked if the passwords are strong enough. Nowadays it is used WPA2 also, an encryption that has no known weaknesses. A new protocol for Qos is WMM and makes Wi-Fi better for voice, video applications, and power saving methods. To make enable the WMM feature all devices in the network must support it. Disadvantages of Wi-Fi Wifi in Europe use for the 2.4 GHz band (1-13) channels, in US (1-11) and Japan (1-14). A Wi-fi signal occupies around five channels in the 2.4 GHz resulting in only 3 non-overlapped channels in the US: 1, 6, 11, and four in Europe: 1,5,9,13 Power consumption is too high compared to with other low bandwidth standards, such as Bluetooth, making a concern about devices batteries life of the. WEP (Wired Equivalent Privacy) is the most usual wireless encryption standard that is used, but shown that can be easily breakable. Wi-Fi Protected Access (WPA, WPA2), solved this problem and its available on most products. Most Wi-Fi Access Points have default the security disabled thought, providing open wireless access to their LAN. You can always turn on the security by configuring the device, usually via the graphical user interface (GUI) of the router/access point. Unencrypted networks can be used to read and copy data that are transmitted over the network, unless we have a security method to secure the data, such as VPN The wireless networks have limited range. A typical Wi-Fi home router using 802.11g with a stock antenna might have a range of 35 m indoors and 95 m outdoors. Range also varies with frequency band. Wi-Fi in the 2.4 GHz frequency block has slightly better range than Wi-Fi in the 5 GHz frequency block. Outdoor range with improved (directional) antennas can be several kilometres or more with line-of-sight. IEEE 802.11g-(2003) When the range increases the performance of a wireless network is decreased. Ethernet or other cables are more reliable then wi-fi. An Ethernet connection can reach speed up to 1Gbit/s and in the other hand 802.11g networks have a maximum of 54 Mbit/s. Protocol 802.11n try to improve the speeds, but still does not achieve Ethernets reliability. People with adsl2+ can understand an increase in performance using wired connection rather than WiFi. Wi-Fi in many cases has problems with the signal-to-noise ratio (SNR). SNR compares the level of the desired signal to the background noise. This can be a huge problem in high-density areas. All the devices must support the same protocol for example 802.11g. And in case there are other access points in the network, the name (SSID) must maintain the same. In Wireless networks there are many times incompatibility problems between brands. Different standards may disrupt connections or low speeds. The new protocol 802.11n use 5 GHz band and have more channels available. Each node (access point, repeater) on the network is able to see the communication between other devices, allowing network traffic to be easily captured. When a WiFi network is not encrypted it is vulnerable to attacks. Wi-fi is a new technology and still under development. Many people may adopt it cause it produce a non wire environment and others not. I think wi-fi will give better quality in the future and maybe it will get pass some main problem that it have at the moment.

Balanced And Well Rounded Education Education Essay

Balanced And Well Rounded Education Education Essay According to the mission of Singapore Education, the purpose of Singapore Education is to provide our children with a balanced and well-rounded education, develop them to their full potential, and nurture them into good citizens, conscious of their responsibilities to family, society and country. (http://www.moe.gov.sg/about/yearbooks/2005/pdf/mission-vision.pdf) Eventually, they would become the future leader who would make the right decision for their nation in future. Thus, the Desired Outcomes of Educations (DOE) is being introduced at 3 key stages, namely primary, secondary and post-secondary. It acts as a checklist or common purposes for the educators to help students strive towards the mission of Singapore education. To better achieve the desired outcomes of education, Teach less, learn more (TLLM) comes into picture in 2005. At the National Day Rally in 2004, Prime Minister Lee Hsien Loong called on our teachers to teach less, so that our students could learn more. (http://www.moe.gov.sg/about/yearbooks/2005/teach.html). This policy is focusing on improving the quality of interaction between teachers and students. The aim of this policy is to drive Singapore education to a direction where teachers only act as a facilitator, nurturing students to become self-directed learners and individuals who are capable of think independently. Teach Less, Learn More is a call to re-examine the fundamentals of teaching and learning why we teach, what we teach and how we teach. (http://www3.moe.edu.sg/corporate/contactonline/2005/Issue13/glossary/glossary.htm#ttml) TLLM reminds teachers that their responsibility is to stimulate the students passion in learning so that students are willing to take up challenges that come to them. Disseminating the information to the students should not be the only way to teach. Teachers should always check for the understanding of students by relating them with the materials. Other than that, teachers should help students learn that they are taught to live the tests of their lives, not to learn that their lives are full of tests. The TTLM initiative also calls on teachers to focus on the whole child instead of the subject. Teachers should put more emphasis on the teaching of good values and attitudes to the students, not their grades. In addition, teachers need to help students learn that the learning process is far more important than the results or the end product. Before jumping into the answers, teachers should treasure the teachable moment by throwing the questions to the students. Let them think and encourage curiosity. TLLM urges teachers to engage student more in learning and depend less on drill, practice and rote learning. Teachers should do more guiding, facilitating and modelling and do less telling so that students could take ownership of their own learning. Every student is different. Therefore teacher should apply various differentiated pedagogies to suit students learning. Student should be accessed more qualitatively over a period of time, and less quantitatively through one-off and summative examinations. Lastly, teachers should promote the spirit of innovation and enterprise among students. I come across one journal that was published in 2005 mentioned that in response to the TLLM policy, MOE was going to provide more time and space to teachers to do the right things for the students. To date, MOE has really made some moves to provide teachers more time; such as assigning a Co-curricular Programme Executives to each school, hiring more new teachers and introduced the adjunct teachers programme. However, we still see teachers rushing for syllabuses and busy preparing students for all sorts of exams. Not to mention the large class sizes and the accompanying heavy marking load, how could teachers stay fit physically and mentally with so many workloads? I do believe that most of the teachers would like to make their lessons livelier and have more flexibility in choosing the materials and teaching methods. I also believe that teachers do not wish their students go for tuitions. Euphemistically, the textbooks, syllabuses and teachers handbooks are said to guide teachers in teaching. As a matter of fact, these materials confine teachers way of teaching. Time allocated to each subject in school is just enough for teachers to run through the concepts and basics due to the tight syllabus. Eventually students would need to sit for the standardized tests, which decide their future. To score high for the standardized test, frequent and repeated practices based on the concepts and basics taught are inevitable. And this is the main reason for the increase of tuition centers in Singapore. A lot of parents have the habit of paving the way that would grant successfulness for their children. These include house moving and become school volunteers to get their children admitted into a good school; send their children to enrichment classes and tuitions in hope that their children could pass standardized test with flying colours. Eventually, their children could get admitted into the university, studying a popular subject which promise good prospect. For most of the students, they bow to the reality at a very young age. Since young, under the influence of the media, friends, community, teacher, school and parents, they got the impression that only by doing well academically; they could have a bright future. If they find the subject or what was taught is not going to help give them promising future, even though they know that is their strength or they have passion on that, they would not pursue them. Students rather give up their passions than face failures. Civic and moral education (CME) is supposed to be the subject that helps students develops their characters and values. Good values, attitudes and characters could also be taught in other subjects; but character development and values education are not their emphasis. Recently, MOE has just completed revising the CME materials, which claim to be more interesting and could engage students more. However, a lot of people do not see the importance of the CME subject; probably because of it is not examinable. Many mother tongue teachers have experienced their CME classes being hijacked by the math and science teachers to rush for syllabuses or to prepare students for exams. The hijacking becomes more frequent especially when the exam period is approaching. School leaders are aware of that but turn a blind eye to it. This indirectly acknowledges that the schools are still more prone to grades-centric instead of values-centric. Thus, it is not surprising that students would have the percept ion that CME is the least important subject and they are less likely learn the subject by heart. Singapore is a country that adopts a highly centralised education system and a strong top-down approach in policy-making. (Catherine Chua Richard, 2007) Changes made at the national level often may be difficult to put into practice at the school level. TLLM is one of them. Catherine Chua and Richard (2007) did a study by comparing the science curriculum between two top schools and two mid-level schools. The top schools appear to exercise more flexibility in their curriculum by introducing a more diverse programme. They are placing greater emphasis on research-based and higher order thinking skills, acquiring beyond the basic knowledge. This is in line with the MOEs initiative. The middle category schools are also embarking on introducing and reinforcing some incentive programmes in their schools, especially for those less able students. However, an important observation shows that there was no corresponding decrease in the number of topics taught in class. On the contrary, the numbe r of periods allocated for the science lessons increased in 2005. They also found that the programmes offered by the top schools are more intensive and research oriented than those offered in the middle category schools. By introducing more intensive programme and increase the number of periods, both top schools and middle level schools actually did not put TLLM into practices. These schools rather play safe by teaching more, and add more to the curriculum. This can has negative impacts on the school climate, as teachers will have less time to prepare, teach and interact with their students. Sooner or later, teachers would develop resistance towards government initiatives. (Catherine Chua Richard, 2007) PSLE test is the ultimate test for all the primary students. This test focus on the end result rather than the process of learning. From time to time, different initiatives, including TLLM are being introduced by MOE to better achieve the purposes of Singapore Education. However, PSLE tests on the whole remain untouched. School principals, teachers, parents and students know that no matter what the changes that will take place, at the end, it is the examination that matters. Thus, when MOE first introduced TLLM, many of the principals and teachers would just take that as another initiative that will come and go. In 2009, MOE announced that semester exams for Primary 1 2 would no longer exist. But later announced that mini test would be in place so that teachers could provide regular feedback on pupils learning to parents. So that is a good change or a bad change? Mini tests are still TEST. They could be the replicas of semester test and could end up having few of them throughout the semester. Students stress over exam is still there and hardly reduced. After six years of study, students still need to sit for the PSLE test. This also means that the pace of preparing the PSLE test would be increased once students step into Primary 3 seeing that the time given has been shortened by 2 years. The aims of education policy are to ensure that students not only master scholastic knowledge, but that they are equipped with the knowledge needed to perform well in the globalised economy (Seaton, 2002). In Singapore Education, the decision-making in curriculum policy always lie in the hands of the government. Thus, we can say that Singapore educational policies are the mirrors of the social, economic and political needs of a society. (Catherine Chua Richard, 2007) From the TLLM policy, we can see that Singapore government would like to mould the future leaders in becoming a confident person, a self-directed learner, an active contributor and a concerned citizen. Although TLLM encourages teachers to teach less so that student could learn more, what students actually learn are still very much depends on what would be assessed finally. We still see some schools hesitating to put TLLM into practice. Thus, I would like to comment that TLLM would be just another MOEs attempt to change the direction of education in Singapore school if MOE still continue its traditional reluctance to let go or downgrade the position of the examination system. Education in Singapore is not education but just a huge examination preparation exercise, namely, the high stakes examination system.

Anti-Semitism in The Merchant of Venice :: Merchant of Venice Essays

Anti-Semitism in"The Merchant of Venice" Anti-Semitism in "The Merchant of Venice" Throughout the play, "The Merchant of Venice" William Shakespeare portrays anti-Semitism through many of his characters. Audiences today may interpret the play to be offensive, where as people of Shakespeare’s time would have accepted the play as part of everyday life. The majority of London’s population at the time was anti-Semitic because there were very few Jews living there. Shakespeare’s "The Merchant of Venice" supports anti-Semitism actions and thoughts and therefore it is an anti- Semitic play. Anti- Semitism is demonstrated very strongly through the character of Antonio. It is clear that Antonio is prejudice towards Jews. Shylock confronts Antonio for spitting on his gabardine, calling him a ‘dog’, and scolding him in the Rialto about his moneys. Antonio replies with, "I am like to call thee so again, To spet on thee again, to spurn thee, too"(1.3.140-141). Antonio does not deny his actions and instead of apologizing he says he will do them again. He does not hold back his feelings for Shylock and in a broad sense his feelings toward Jews. In the second act, Launcelot is debating whether or not he should seek a new employer. His problem is that he works for Shylock, who is Jewish. Launcelot thinks to himself, "Certainly the Jew is the very devil incarnation" (2.2.24). Eventually, he decides to run away from Shylock rather than continue working for a Jew. He then presents the argument, "I am a Jew if I serve the Jew any longer" (2.2.104) to his father. Before accepting the new job, Antonio discusses the matter with his father and reminds himself that Bassanio is much poorer than Shylock, b ut that he would much rather work for a Christian than a Jew. Lorenzo harshly insults Shylock when he tells Jessica that if her father ever makes it to heaven, it is only because Jessica converted to Christianity and that is portrayed through the line, "If e’er the Jew her father come to heaven, It will be for his gentle daughter’s sake" (2.4.36-7). Lorenzo describes Jessica using the word gentle. The word gentle in Shakespeare’s time can also be pronounced gentile which means against Judaism. In this quote and later on in the play through the line, "Our house is hell, and the, a merry devil"(2.3.2-3), Shakespeare is informing the reader that Jessica dislikes her father and that the house she has lived in with him is hell.

Race Relations in Modern American Society Essay -- Papers

Race Relations in Modern American Society Race relations are an ever prominent issue in American society. Controversies focusing around race are a commonly seen smeared across the front page of the newspaper or headlining on the evening news. The opposition is usually between a minority group and "The Man," a colloquialism used by many Blacks to refer to the overwhelming power stemming from white racist tendencies. This racial tension can sometimes can cause the oppressed to band together against the oppressor. Many times, the most prevalent link is between the African American community and the Latino community. Here we find two groups of people with very similar lifestyles who find camaraderie between themselves when dealing with America’s racism. Although the specifics may differ, the experiences of Blacks and Latinos, specifically Mexican Americans, has impacted the two communities very similarly. For example, many sociologists agree that the slavery experience is the cause of many problems Black America has today. Things such as "Black on Black" crime, broken homes, high poverty levels and drug problems are believed to have links back to slavery. Much like Blacks, Mexican Americans have problems in their communities today that stem from their dealing with immigration in this country. Their problems still exist greatly because immigration is still going on between Mexico and America. The affects of slavery and illegal immigration began many years ago, continued throughout history and continue into today’s culture. In the late 19th century and early 20th century, Blacks were oppressed with the use of Black Codes followed by the implementation of Jim Crow laws and segregation. These acts of racism have since be. .. ...welfare, those who are gang affiliated, the drug users and those that live in run-down, crowded tenements who suffer from tuberculosis and depression. It forgets the many who are forced to work in sweatshops and live below poverty level. Secondly, the Model Minority Myth is a dangerous concept because Asian Americans are alienated from the majority race as well as the minority race pool. They are still perceived by white America as outsiders yet are set up for resentment by other minorities. This makes life hard for the Asian American that achieves because he is almost forced to turn against his other brothers and sisters of color. This is detrimental to the well-being of the Asian American in this country. This concept should not be used to describe the modern Asian American and should be recognized as a stereotype like any other in our society.

Drug Addiction :: Social Issues, Drug and Alcohol Abuse

According to Webster's New Worldâ„ ¢ Medical Dictionary, 3rd Edition, Addiction is a chronic relapsing condition characterized by compulsive drug-seeking and abuse and by long-lasting chemical changes in the brain. Addiction is the same irrespective of whether the drug is alcohol, amphetamines, cocaine, heroin, marijuana, or nicotine. Every addictive substance induces pleasant states or relieves distress. Continue use of addictive substances induces adaptive changes in the brain that lead to tolerance, physical dependence, uncontrollable craving and, all too often, relapse. Dependence is at such a point that stopping is very difficult and causes severe physical and mental damage from withdrawal (WILLIAM C. SHIEL JR., 2008). Over the past two decades, many researchers have identified subgroups of alcohol and drug user based in similarities like drinking style (Kevin M. King, 2009), behavior problems, etiology, outcome, and other clinically significant phenomena; making the most predominant the antisocial, primarily neurotic, mixed neurotic and antisocial, and psychotic (Malow, 1989). But the antisocial features have been the most prominent between all the subtypes; especially on drug user. This literature will review these thru the following questions: 1. How addiction impact family and social relationships? 2. Do alcohol and drug addictions have relationship with crime? 3. What is the economic cost related to alcohol and drug addiction? How addiction impact family and social relationships? Drug and alcohol abuse is a large problem for adults in our world today. It is destructive, not just in terms of its effect on the addict but for the suffering it inflicts on the loved ones and family (Sadava, 1987). Though the addict may have no conscious intention of harming his companions and relatives, his self-destructive actions are a source of anguish for anyone with genuine affection for him/her. One of the most common situations is when the partner tries to hide the addict’s behavior from family member, co-workers, employer or general public. This type of behavior is known as Codependence (Malow, 1989). A codependent partner will make up excuses for the addict’s work absences or a car accident; even will tries to clean up any legal messes resulting from the addict’s behavior; allowing the addict to continue his destructive path without dealing with its consequences. Consequences that can go from continuous fights to elevated levels of dome stic violence. Most the time related to financial hardships, causes by the addict’s need to buy drugs, as well as from his inability to find consistent employment.

Modern Day Hero Essay

When you head the word ‘hero’ most people picture a buff man, wearing a cape; like Superman and Batman. A hero can be anyone from a family member to someone in the community. I believe my mother can be portrayed as a hero. She volunteers in her spare time, is a teacher, and is a friend to everyone she meets. My mother has a tendency to volunteer for anything, but it’s usually within the school she works at. Before we moved here, she was head of the P.T.A., always finding ways to raise money for the school. She even got a new playground for the school so the kids could enjoy recess without having to worry about injuries. She has also organized many walk-a-thons for kids with Autism at her school. She takes action and is really god in what she does. My mother is also a teacher. She teaches kids with Autism, which I think is great. Especially because she has a lot of patience with those kids. She teaches each kids one-on-one, at their own pace. She takes her time to make sure that each student has an understanding of what is going on. She also makes a connection to her students’ families, and makes sure the parents are involved with their child. She is really good at what she does. My mother can befriend anyone she meets. You can be a complete stranger and she will compliment you, no matter what. This one time we were at shopping at the mall when we saw this lady drop $100 on the floor. My initial thought was to keep it, but then my mother picked it up and gave it back to the lady. In return, the lady brought us all a coffee. Leason being, what goes around comes around. Most people think of hero’s as someone famous and important. I believe my mother is a hero for many reasons. She’s a teacher, can befriend a complete stranger, and loves to volunteer. In my eyes, my mother is what I call a hero.

Poem of William Caslos William Essay

William Carlos Williams is a pioneer who creates a whole new realm in American poetry. He is regarded as an important and influential poet because of his unique and usually plain style. The poem â€Å"Poem† is one of the most prominent poems reflecting Williams’ style of writing. In this piece of work, Williams discusses a central contrast between the mortality of life and immortality of art through the image of two roses – in nature and in poetry. It can be said that life is symbolized by the rose, the central image and also the main theme of â€Å"Poem†. The real rose and unreal one are skillfully used to represent two factors: the reality and the art. In nature, a rose which cannot avoid the cycle of time undergoes stages of nature rules. First, it germinates from a seed. Then, it grows up and blooms or blossoms. Next, it fades or discolored. Finally, it dies. â€Å"The rose fades – And is renewed again – By its seed naturally† (Williams, 1983). The issue of the rose fading show that life, no matter what forms, follows the nature changing rule and eventually fades away. Meanwhile, Williams uses the image of the rose in poem to respect the art because the real rose will fade naturally but the rose of art keeps an ever-lasting beauty: â€Å"Save in the poem – shall it go – to suffer no diminution – of its splendor† (Williams, 1983). Generally, the whole poem presents the central contrast of nature versus art, death versus life and cycle of time versus perfection that lasts forever. With respect to the highlighted image of the rose in poetry, it can not be touch but lives forever and remains perfect, fresh, young, and beautiful regardless of time. It has the empowerment of splendor, perfection, and immortality. In fact, Williams’ intention after his words of praising the power of the rose in poem is to advocate the power of art in general. It seems that the poet gives prominence to art whose role is to inspire and guide people through curves of life thanks to its beauty and significance of teaching truth, giving beauty and pleasure, shaping moral characters, showing power of language and showing human experience.
