Essay about Security Wi Essay about Security: Wi-fi and Wireless Access Point Thesis What is my project (statistics.gov.uk/cci/nugget.asp?id=8) The UK has a very intensive Rail network system which spreads out across the whole country. It is used by millions of users. There is currently 21000 miles of track lied out across the network. According to statistics.gov.uk in the year 2010 1.32 billion people used the trains. This is statistic show the magnitude off the rail and that there is hugh potential in using is client base. According to national statistics 30.1 million adults in the UK where using internet every day, this is more then 60 percent of the adult population. In line with the amount of users now online they has also been a rise in users watching TV and Listening to the radio over the internet which in 2010 reached 17.4 million a day. Social networking has also risen in popularity with more then 65 percent of those online users using different types of social networking websites, chat rooms and blogs. What this shows is that we are living in the digital age were 70 percent of us need to be able to access information from the web. Now we now that there was 1.2 billion user of the rail network and we also now that more then half of the UK adult population use internet daily. We therefore argue the point that more then half of the rail network users use internet which means more then 600 million users of the rail network are internet users. Another statistic tells us that a recent study has shown that more then 80 percent of the adult population carry a mobile phone and 40 percent of those are wifi enabled. While on a trains user mostly access the internet via their mobile network provider, and this service is not great while on a fast moving train. User encounter loss of signal poor reception and rarely seem to have a good connection at all. The aim of my project is to provide a constant internet signal on a moving train utilising wireless connectivity. This will aloow users to connect to the internet while on the train using any wireless enabled devices such as Tablet Pc, mobile phone, laptop exe.... As wifi signal from one router is limited I will be intending to use many routers which will run along the train track. Power to them will be provided by the power terminals already existing along train track and phone-line. This will provide train customers to access internet constantly through out their journey with no loss of signal and speed. What will I use: Types of technology available for accessing the internet (http://en.wikipedia.org/wiki/Broadband_Internet_access) accessed on 16-02-2011 Mobile Broadband (explainthatstuff.com/mobilebroadband.html) There are two ways in which you can connect to a mobile broadband, if you have a smart phone which has HSPDA you can access fast mobile broadband or you can purchase a USB Dongle from most mobile network providers. Most major cities in the UK are covered by the 3G network Advantage The advantage of using mobile Broadband is that it has a larger coverage then wireless network. Where ever you can get a reasonable mobile connection you are more than likely to get a good mobile broadband connection. Disadvantage Mobile broadband has its downsides, as you are using the mobile phone provider’s network the quality of the signal you receive can vary from a good signal to a very poor signal, thus loss of connection occurs. When using mobile broadband on a train you can expect to lose connection very often as trains go under tunnels and bridges, this makes for a bad user experience. Satellite Broadband (http://computer.howstuffworks.com/question606.htm) (pcworld.com/article/17617/how_it_works_satellite_internet_access.html) High speed internet that uses a satellite dish on the receiving side similar to what satellite TV uses. The way in which internet is accessed is very similar to how Satellite television is received, a BIRD orbiting the earth beams down data to your dish. The way it works is you

Breaking Down The CompTIA Security+

Breaking Down The CompTIA Security+ Over the last decade or so, IT security has exploded as a field, both in terms of the complexity and breadth of the subject matter, and the opportunities available to security-focused IT professionals. Security has become an inherent part of everything in IT, from network management to web, application and database development. But even with the increased focus on security, there is still much work to be done in the field, and opportunities for security-minded IT professionals aren’t likely to decrease any time soon. The Importance of Certifications For those who are already in the IT security field, or are looking to enhance their career, there is a range of certifications and training options available for those who want to learn about IT security and demonstrate that knowledge to current and potential employers. However, a lot of the more advanced IT security certifications require a level of knowledge, experience, and commitment that might be outside of the range of many newer IT professionals. A good certification to demonstrate basic security knowledge is the CompTIA Security certification. Unlike other certifications, such as the CISSP  or the CISM, the Security doesn’t have any mandatory experience or prerequisites, though CompTIA does recommend that candidates have at least two years of experience with networking in general  and security in particular. CompTIA also suggests that Security candidates obtain the CompTIA Network certification, but they don’t require it. Even though the Security is more of an entry-level certification than others, it’s still a valuable certification in its own right. In fact, the Security is a mandated certification for the US Department of Defense  and is accredited by both the American National Standard Institute (ANSI) and the International Organization for Standardization (ISO). Another benefit of the Security is that it’s vendor-neutral, instead choosing to focus on security topics and technologies in general, without limiting its focus to any one vendor and their approach. Topics Covered by the Security Examination The Security is basically a generalist certification – meaning that it evaluates a candidate’s knowledge across a range of knowledge domains, as opposed to focusing on any one area of IT. So, instead of maintaining a focus on application security only, say, the questions on the Security will cover a broader range of topics, aligned according to the six primary knowledge domain defined by CompTIA (the percentages next to each indicate the representation of that domain on the exam): Network Security (21%)Compliance and operational security (18%)Threats and vulnerabilities (21%)Application, Data, and Host Security (16%)Access control and identity management (13%)Cryptography (11%) The exam provides questions from all of the domains above, although it is somewhat weighted to give more emphasis on some areas. For example, you can expect more questions on network security as opposed to cryptography, for example. That said, you shouldn’t necessarily focus your studying on any one area, especially if it leads you to exclude any of the others. A good, broad knowledge of all the domains listed above remains the best way to be prepared for the test. The Exam There is only one exam required to earn the Security certification. That exam (exam SY0-301) is comprised of 100 questions and is provided over a 90-minute period. The grading scale is from 100 to 900, with a passing score of 750, or roughly 83% (although that’s just an estimate  because the scale changes somewhat over time). Next Steps In addition to the Security, CompTIA offers a more advanced certification, the CompTIA Advanced Security Practitioner (CASP), providing a progressive certification path for those who want to continue their security career and studies. Like the Security, the CASP covers security knowledge across a number of knowledge domains, but the depth and complexity of the questions asked on the CASP exam exceed those of the Security.​ CompTIA also offers numerous certifications in other areas of IT as well, including networking, project management and systems administration. And, if security is your chosen field, you might consider other certifications such as the CISSP, CEH, or a vendor-based certification such as the Cisco CCNA Security  or Check Point Certified Security Administrator (CCSA), to extend and deepen your knowledge of security.

Total SA Essay Example | Topics and Well Written Essays - 2750 words

Total SA - Essay Example The investors generate dividends from their investments. Investors receive dividends based on the prior year’s net income performance. With higher net income, the investors will automatically receive higher dividends (Warren, 2009). Further, the investors can also generate gains from the selling of their TOTAL SA investments (Crosson, 2011). If the investors are able to sell their investments at a bid price that is higher than the investors’ cost of investing in the TOTAL SA stocks, the investors generate gains. When economic depression or unfavorable economic constraints crop up, the investors may be persuaded to sell their investments in TOTAL SA investments at prices at an amount that is lower than the investment price. When this occurs, the investors generate stock exchange losses (DuBrin, 2009). TOTAL SA Company’s structure in relation the organisation’s goals, aims and objectives. The TOTAL SA organisation structure fittingly enhances the accomplishm ent of organizational s goal, aims and objectives (Daft, 2011). With more investors, the amount of investment is higher. The investors’ money plus TOTAL SA Company’s use of long term loans increase the amount of assets. The TOTAL SA Company maximizes the total assets to generate revenues (Weetman, 2006). Further, the stockholders’ investments and loans ensure accomplishment of the company’s goal, aims and objectives (Ferrrell, 2010). The company is able to establish oil and natural gas exploration development contracts in different strategic locations around the world. The cash inflows from loans and stockholders’ investments are successfully used to refine petrochemicals. The same finance amounts are used to manufacture the chemical product needs of the TOTAL SA Company’s current and future customers (Nutt, 2010). Specifically, the TOTAL SA Company specicalises in selling elastomer-based products (Total, 2012). The company also sells adhesi ve products. Another major product of TOTAL SA Company is classified as electroplating items. The bulk of the company’s profitable products falls under the petroleum market segment. The investments are used to foster company’s trading and shipping of petroleum chemical finished goods (products). Moreover, the investments and loan amounts are used to sell the finished goods (Baumol, 2009). The raw petroleum extracts are processed into finished goods. The TOTAL SA Company finished goods include the top selling Liquefied Petroleum Gas products. Another finished product is home heating gas. A third finished product is asphalt petroleum products. The fourth finished good type, asphalt, is used in the paving of the highways and smaller roads. The fifth finished good classification, lubricants, is a very popular lubricating product group (Total, 2012). Further, the investments and loans are used to generate a big share of the global energy market segment. The funds are used t o realize generating an increase of 2.5 percent production output every year (Total, 2012). The funds are used to maximize the company’s scarce asset resources. The scarce resources are used to expand the oil production facilities (Fabozzi, 2011). The company continues to set up new oil production facilities in new oil fields. The investments and loans are used to quickly set into motion cost reduction activities. With cost reduction, the

The needs of future generations are being met by current policies of Essay - 2

The needs of future generations are being met by current policies of sustainable development. To what extent do you agree with this statement - Essay Example It defines it as the development that satisfies the current human needs without reducing the availability of the resources to the future generations. It breaks it into two concepts. The first concept concentrates on the needs and in particular the needs of the poor. Its second approach is on limitations. Its approach on limitations focuses on social and technology factors, and their ability in ensuring that environment use meets the present and future generations wants (Dobson & Lucadrie 2002, p. 85). It further defines development that is sustainable as the progressive transformation of the society and economy (Dobson & Lucadrie 2002, p. 85). It is, therefore, vital to concentrate on the three pillars of sustainable development; social, political, and economic factors to ensure the continuity of future generations. Researchers are of the opinion that governments still believe on the old development paradigms. They emphasize on economic growth while believing that other industrialized countries have made no changes to their patterns of production and consumption that threaten global resources. Meeting the goals of sustainable development require genuine institutional and political will by governments in all countries. The countries should contribute to it regardless of whether they are developed or not (Purvis & Grainger 2013, p. 177). Weak law enforcement, corruption, and ineffective governments are obstacles in achieving sustainability. Limited policy capacity, lack of information, and incompetent decision makers are some of the reasons for the minimal cooperation by governments. The World Summit discussion on Sustainable Development held in 2002 in South Africa maintained that the sustainable development has not evolved out of its roots. Focusing the issue on an environmental direction rather than integrating with an all-round development perspective is a mistake. The political agenda replaces

Ferris Bueller: Possible or Not? :: essays research papers

Ferris Bueller’s Day Off Possible or Not?   Ã‚  Ã‚  Ã‚  Ã‚  Ferris, Sloane, and Cameron spend one amazing day ditching school, exploring the great city of Chicago and take time to visit many landmarks and take part in many exciting activities. The day depicted in the movie would be a great and exciting day for anyone, but is it possible for them to have done all of the things they did in one day? I believe it is reasonable to believe that Ferris and company may have been able to do all the things they did in the movie in one day.   Ã‚  Ã‚  Ã‚  Ã‚  The first thing that needs to be looked at is where Ferris lives. Ferris most likely lives within 10 minutes of his school considering he lives in the Chicago area and there are many high schools, he wouldn’t live too far from his high school. That is all just logic. Ferris’ school was shot at Glenbrook North High School which is at 2300 Shermer Road Northbrook, IL 60062. Using this site and assuming Ferris’ house is ten minutes away the journey begins. It is assumed that Ferris and Cameron pick up Sloane at 10 a.m. from school so this is when the timing starts. From school they head to downtown Chicago in Cameron dad’s 1961 Ferrari GT California, which has a top speed of 155 mph . Despite this we can assume that with Ferris driving, and him being a very daring and confident teenager, he was likely driving between 80 and 90 mph on the open freeways to downtown. Ferris had to travel about 22 miles to the parking garage in downtown Chicag o, 18 of which were on a freeway. Assuming Ferris drives about 80 mph it would take him less then 15 minutes on the freeway and probably another 10 minutes on surface streets to get to the parking garage. The parking garage was located on the corner of Madison and Wells in downtown Chicago. This would make the time about 10:25 a.m. when they reached the parking garage to drop off the Ferrari.   Ã‚  Ã‚  Ã‚  Ã‚  From the parking garage Ferris and his friends go to the top of Sears Tower and look down. It is approximately a half of a mile from the parking garage to Sears Tower. Walking briskly because they are excited about ditching school it can be assumed it took them about 10 minutes to walk that half mile.

This semester music class has taught me a lot on basic functions of musical sound, elements of music, and what a common beat is. When we first started class we discuss all this information and I received a lot of knowledge from it. For example duple means 2 beats per minute, and triple means 3 beats per minute. Understanding these elements enhances our listening, provides vocabulary for discussion, and increases our capacity to enjoy music. What stood out to me the most in class is how each musician we talked about had a story to tell through their music. For example Woody Guthrie with the song â€Å" This land is our land† was a great protest song. It was written in reaction to the great depression and how people couldn’t find work. This†¦show more content†¦Evelyn made history for every musician with a disability to go out in the world and follow his or her dreams. Evelyn was deaf but she could play better than most musicians that weren’t deaf, she re ally stood out because people were shock of how good she played being deaf. Evelyn’s drive and motivation to do something no matter how much people said she couldn’t do it she did it anyways. Which makes me feel comfortable to do anything I want to do in life. Regardless of how people may look, think, or even judge you. Looking at the video we had to watch outside of class you could tell she just loved what she was doing. If I never knew anything about this lady I couldn’t even guess she was deaf because how good she plays and interacts with her audience. Being in this class has defiantly given me a new perspective on art and music. With me I only listen rap and never was interested in trying other selections of music until this class. Being able to get a better understanding and background information of country, classical music, and rock and roll makes me appreciate the music a lot more. What I have enjoyed more than before is modern jazz. I love the peacefuln ess of the jazz music. It’s a lot more soothing than rap music I must admit. Sometimes I need that music that allows you to escape from all the frustration, anger, and sadness that may have been built up and turn to modern jazz which has been my problem solver.Show MoreRelatedStatement of Purpose23848 Words   |  96 Pages................................................. 36 Ohio Wesleyan University Writing Center  © 2011 IV.
